The main problem is that they're hot as hell, you'd have to let them cool down to do any maintenance, Tesla's grid storage you can just open up an box and replace some bits, they probably did a bunch of times already, how much would this have cost with liquid metal batteries?
I bought us a roborock s4, I think? It's honestly our favorite thing. Our kids make messes all the time and we wake up every morning to a clean floor. We nicknamed it "Dusty".
I would suggest anyone interested in this battery tech go and watch Dr Sadoway talking about it. My favourite takeaway is his statement, "if you want it dirt cheap, make it from dirt".
He has been pitching his ideas (8+ years) for a long time and nothing has come of it. You can look at his old YT videos and see my comments from years ago asking when we will see this in production. It is always "a year or two away". Professors do "research" as a way to make extra money and we are talking big bucks. They have their undergrads and post grad researchers doing the work and they take piece of the grant money for the "advising" they do research.
I think people have to get away from the "one size fits all" approach. Stationary large battery banks for grid buffering, house batteries and vehicle batteries have different requirements. Drivetrain requirements are different for different vehicle classes etc. We should be open minded and develop the solutions that are most efficient for their use case.
@@contradictorycrow4327 Well it depends on what "Monopoly" or "Oligopoly" you talk. Why are all trucks diesel? Why is the default for individual mobility an automobile? Why is electric energy storage LiPo? one size fits all is not a sustainable answer.
@@TheCloudhopper But people like simple Questions and Answers. What is best is the most asked question and the Answer is treated like a religion. There is no place for "...for that specific purpose" in this question, as there is no place for a second good in Judaism and it's two big offsprings.
Of course there are different needs at different scales. Dr. Sadoway tossed out the idea of scaling up lithium ion batteries from iPhones right from the beginning. He started from a crisp sheet of blank paper with what he knew: electro-metallurgy. Ambri has the potential to hit one out of the ballpark with massive grid-scale power storage in a few years and leave li-ion stuck on first base with smartphones, vacuum cleaners, EVs and Powerwalls.
@@ub59 I am very encouraged, I saw a video where he was interviewed and was asking myself: when do they announce the next stage ? Looks like they still have funding, they have the test projects for 2022, and the tech is not _that_ complicated so that could work. 30 % or 50 % drop in costs for robust batteries - that would be a game changer. Not only do they cost less, they would also work much longer (not sure if that was factored into the calculation at 10:50). Never mind even if they broke it down to storage costs per kWh over 10 years .... 30 or 50 % less is huge. That will speed up LARGE solar installation by people who have the space or want to invest in a community project. And the projects will be more viable while also reducing grid peak demand. (the large providers do not like that, they make more money with peak demand, some providers in Texas make ONLY profits because of A/C peaks in summer. The rest of the year they hang on. Which explains why no one "voluntarily invests in winterization of the Texan electricity production.
Yep we need to , but cost scaling via capitlism and globalism dictate that a homogenous product is cheaper overall so we get square peg round whole solutions for the most part
That looks like a viable technology for large installation grid storage. Would be especially useful with solar arrays in desert environments. Nicely done video
You know what would also work for half the environmental impact? A natural gas generator operating intermittently. Utility scale storage has the potential to make everything much cleaner.
I see great things ahead for liquid metal battery’s, and not just the main one you discussed today, but many different potential chemistries along the temperature gradient scale. This is very interesting technology and I pray that several of these can make it past the scaling issues and become useful as quickly as possible.
You didn't mention the biggest short-term challenge for Lithium-Ion: there's not enough production capacity for the necessary raw materials, and the producers might not be able to scale quickly enough. Complementary technologies that use different raw materials are extremely important. Liquid metal batteries are particularly interesting because they tolerate (and even benefit from) high environmental temperatures. Most types of Lithium-Ion degrade quickly when used at high temperatures. Unfortunately, the Ambri battery is in the very early stages of mass production. The first (and so far, only) planned project, the 250MWh battery in Reno, is planned to be delivered to the customer from 2021 through 2023. At that low, pilot scale production rate the technology is useless. If they can't scale production very rapidly it may never be economically competitive.
I always saw Reno as a way to show that it works. Seems to be metal cases stored in a small shipping container that hold the battery. The battery also go from a solid(discharged) to liquid (charged) so transportation is easier
You know lithium ion batteries come in many different forms. Lithium iron phosphate batteries kill everything. For home or grid scale storage Sodium may replace lithium one day. Then that's all that's needed until fusion can be achieved
@@tigertoo01 Yes, I know. But LFP, like all types of LIB still need battery-grade Lithium and Copper. Both of these could be scarce for a couple of years. Sodium Ion might be a great alternative/complement if it materializes quickly enough.
@@w0ttheh3ll Agree that its not just a given there will be enough of anything but just looking at the current production and known reserves there is enough lithium for 100's of millions of EV's with a 60kwh battery. With Telephony and the internet merging and optical fibre and wireless communication becoming more main stream, Copper uses have reduced so the EV demand on copper is not as great as some believe. Still we will need a billion + EV's on the road. Unless autonomous driving becomes real and lives up to promises then the number of vehicles on the road may drop significantly. I think we should plough on with building EV's with current battery tech and hopefully it will lead to significant breakthroughs not only in battery storage but recycling too.
@@tigertoo01 I'm not saying there isn't enough stuff to dig up, just that there will be short-term shortages because not enough digging is happening right now. Of course we should, and will, continue to build as many EVs as we can with the best tech we have available.
What future we all die we don't have a future, we have a limited life span,. Live your life for goodness sake. Future the oldest of us live for a hundred years but mostly we between 65 and 75 years and besides that at any given something can end our lives, which means we have to options be scared or live. You do have future neither do I or anyone else, the future the past only exists in your mind otherwise not.
@@beelot1511 lmao that guy is so mad his grammar started degrading he says no one has a future and I'm not going to argue that, but for sure he doesn't have a future as an english teacher, that much I can tell
Love it. Ambri has been at it for 12 years now, spent $100+ million. Battery chemistry is hard! And you have to prove lifecycle operation before anyone buys it. Cant wait to see these in operation.
Replacing “most popular” with “most popular for new installations” and “widespread” with “not geographically constrained” makes the statement true. He should be more accurate in word choice, and also explain in this video about grid scale energy storage the pluses and minuses of the major players, which MUST include pumped hydro, since it’s the clear leader in installed electrical energy storage in both GW and GWh comparisons.
That’s a good point. You could have this in a little shed at the foot of a small road with, say, 10-20 houses. Maybe it’s saving up that same street’s solar and/or wind and supplying it back as well.
The sheer amount of work that we need to do in order to make mass energy storage viable just goes to show that we also need to be reducing our power dependence wherever possible. This means building denser cities so we can walk and bike everywhere and take advantage of shared surfaces in apartments to reduce heat loss/heat influx so less cooling and heating is needed.
@@destiny_02 Not at all true. One, if it is in equilibrium with its environment, that means it environment is literally so hot that it is melting, so unless you are in a volcano you are not going to be in equilibrium. Two, even if it was in equilibrium, that's not where the energy storage comes from. The energy is stored by the transfer of positive ions from one end to the other, not thermal energy.
Great technology for grid energy and would free up lithium ion cell production capacity for other critical sectors like transportation. These two sectors are the largest in terms of emissions.
I've been waiting for more recent news about Ambri's work. I was concerned about their status, because their Wikipedia page talks about layoffs and reductions, but this is great news. For truly northern latitudes with truly brutal winters, these 'hot' batteries seem like a much better solution than lithium battery technology. That it has been done by this high-quality UwMF channel is just a bonus! Thank you!
Great video, as always! Addendum to deep-cycling Li-Ion batteries: If it's an Apple Ipad, deep cycling just a few times will kill it completely in a matter of weeks, forget about two years. Worst battery EVER. I had to get that off my chest. Thank you.
Best video so far on the liquid metal battery! It's worth noting that Ambri is comparing their active material cost to LCO ($51/kWh), which is the most expensive lithium ion chemistry. LFP (Iron) is much cheaper at $8/kWh active material cost. Nickel will achieve ~$20k in the next few years - which is near Ambri's $16/kWh. Furthermore: How much are the inactive material costs for Ambri? I'm assuming they require a lot of expensive thermal protection/insulation.
@@commentsboardreferee7434 You gonna pay for everyone, everywhere, to transition to "green" energy overnight? If so, great. If not, a slower transition is a vastly more practicable solution.
@@brianfhunter well, I must admin I had to where with at least some study that that girl had to say, but also disable disagree with all-around approach and general fundamentalism. We should definitely limit fossil fuels as much as possible but in no way IMMEDIATELY and as said here, there is no one single technology to save the day (no non-nicméně technology anyway). Edit: Plus I think internal combustion engines for personal transport should serve us for years to come (together with other solutions tailored to their specific purposes) instead of being showcase of how serious we are about climate change while doing nothing about other, more damaging but less visible industries.
At first I was disappointed by only 37 reviews but other products from the same company have thousands of reviews so it appears worthy of consideration.
At that price I’d highly consider the Dyson product this is cloning tbh. I don’t have anything against product cloning but if you’re almost the same.. but anyway I’ve got an older one of this style, the Dyson one, it’s actually good enough to replace a plug-in upright vac if your place isn’t huge. So that’s nice for storage reasons in an apartment. This is a god use for the power delivery of lithium batteries, to get the suction, so I can see this becoming an increasingly common form factor.
@J Hemphill yes I know the attributes and flaws of a robot vacuum, and you need to supplement manually its losses. But when 90% of vacuuming can be automatically done, and once you own one you realise how much time you save. All I'm saying is I had to laugh at someone trying to selling me a manual vacuum. btw, my robot spot cleans, doesn't bumble, and also mops my floor, all while I'm at work, does an excellent job and saves me 35 mins of mindless manual labour per week. Look I get it, hes just advertising his free vacuum and who wouldn't. But if you've going to spend that much, get a robot, because you wont regret it.
The down sides in using liquid metal batteries are efficiency (80%) and charge leakage. On the positive side are potentially low cost, stability, and longevity. Ambri is a clear competitor to Tesla in the market of grid level storage. I wish them well in their ramp to production.
It seems like it is fundamentally a cost / maintenance question. It feels like the core components are good, but all the components that need to interact with them are questionable. Anode, cathode, whatever heater is used to heat it up when necessary, and the casing. Few materials seem like they would do well sitting in a molten metal bath. And the failure modes if anything was punctured. But if the cost per VA is good and you have a stable installation it could be quite good. Less space than pumped water storage. Probably lower temperature than the molten salt designs for solar.
One of the stories told by the developer is of a US military group came to see the molten batteries. The first military guy immediately says, “ what happens if this thing gets hit by gunfire ? “ the second says “ the molten metal cools as it exits the hole and plugs it “ . Number one says “ so the battery is self sealing “
I don’t think you would put a resistance heater in a metal bath, the metal bath would cause a short , the resistance elements would be outside the bath with some thermal path to the metal.
I'm so excited for this technology in my home state of Arizona! It just seems like such an elegant solution for our solar advantages! I hope this technology continues to develop.
They sound rather dangerous running at high temperatures. So, maybe good for large grid storage, but not so much for home use where home owners would have to maintain it themselves.
Here in south africa battery theft is a big issue. Mobile networks often have their tower batteries stolen. The network operators build serious steel cages, concrete barriers and many things to make it as hard as possible to steal... but they are still stolen. Some batteries are in the concrete itself to protect it.
I get that this is intended for Grid level applications but It also seems like a good fit for home solar installations. Once installed, movement is also a non issue like for grid level energy storage and the deep cycling capability and projected reliability seem very compatible with solar installations on homes for off grid independence or emergency power during outages. Perhaps costs can become competitive in the near future for home use.
@@gregbailey45 so great for running the fridge, the stove, the AC, the heating (heat pump hopefully so roughly same electrical load as AC), the TV all day, etc etc
@@gregbailey45 In a home solar installation there would ideally be on average 12 hours of charge during the day and 12 hours of discharge after the sun goes down.
We need to convert gas stations to charging stations and use this type of tech to replace the holding tanks. Then the infrastructure for most cities will be properly engineered to be more renewable energy ready and sustainable. 3MW perstation would be appropriate storage.
@@UndecidedMF - check out LiNa Energy (lina.energy/) - solid state sodium battery technology - abundant raw materials, cheap, high performance and safe! We'd love to inform a sodium battery review...
Your reminders that there isn’t one technology to rule them all is a good one as it is so easy to become convinced that one technology in particular must be the solution. Thanks again for your insights!
Thanks, interesting stuff. However, I plugging for aluminium ion. Compared to lithium ion have 3 times the capacity Durability not there yet but improving and looks promising
It's worth noting that the thermal management of these systems is not anywhere near as problematic as it may sound. Blacksmiths have been working iron since Roman times, and getting iron to forging temperature means getting it upwards of 1300 degrees Celsius. And that's a furnace you're actually working next to, putting stuff in and out of, and straight up hitting the thing you've just pulled out of it with a hammer. Getting a battery you set up and largely forget up to less than half that should not be difficult for modern engineers to design safe insulation for.
I think this is a GREAT idea! We need to allow the incremental changes toward solving our problems get us to full, democratized energy freedom. These batteries are scalable enough to allow a small town in the middle of Iowa to go off-grid (air-storage batteries as another example). These solutions allow the town or coop to determine their own needs without big companies forcing their weight on them. Thanks for highlighting these!!
I have been watching Don Sadoway for years, and am waiting patiently for Ambri to provide a home battery. Being everything is liquid, no dendrites. I would think baffles could make the battery earthquake resistant.
There was a recent fire of an electric car in an archway below a station in London. That caused mayhem and caused the train station to be shut and trains to be rerouted and cancelled. It just shows how bad they can be.
@@HamRadio200 You haven't yet figured out the reality of global warming causing disruptive climate change, so you are not in a position to be critical of the research or sources of Matt.
I wish you had mentioned that the batteries maintain their own operating temperature through regular charge and discharge cycling. It is an important part of the conversation. People seem to assume there is a need to keep them hot to keep them liquid where as they are able keep them selves hot through regular use.
Since it's based on a liquid, how scalable is it? Could you theoretically have one giant pool of 'liquid battery', or is there a limit to how large/small it can be? I assume the distance between the anode and the cathode can't be too far, so this pool would have to be very long, but thin
This and "molten salt" batteries are better in multiple smaller cells than one big pool as the larger the cell the more difficult it is to keep a consistent temperature throughout.
It probably comes down to operability, many smaller cells are probably easier to transport/maintain than a huge single cell. More modular as well, so it'd be easier to scale up over time. And, if one fails and is somehow destroyed, the others can be relatively isolated thanks to their enclosure. So there's probably a sweetspot, and going bigger than that doesn't make much sense for safety and maintenance.
@@Michelino_M5 The main advantage of being smaller is maintenance. Even if it was exactly the same efficiency at massive scale, operators would still choose smaller components that are strung together. If one little battery fails, you pull it out of the rack and lose a minuscule amount of power storage. If a massive battery fails, you may have to take a massive chunk, if not all, of the facility down for repair. And replacing an Olympic swimming pool of gallium is a lot harder than tossing a couple replacement units in a standard truck.
@@Beakerbite Yeah, that was the first thought that came to mind. But also consider how hard it would be to deploy such a huge pool of molten metal, from the factory to the site where it would be used.
I couldn't more highly recommend watching Donald Sadoway's MIT lectures on RUclips, on Solid-State Chemistry. He's the best teacher I've ever seen on the subject, hands down
“No, one technology to rule them all, having options…” agree, yes, options, like nuclear power that should recognized as a strong player in the fight against fossil fuels.
I agree. Replace fossil fuels with a highly energy-dense and practical solution until we have the time to *experiment* with a less-dense source (which is what we are doing as the situation gets deeper)
Safety and co$ts. Hippies didn't kill fission, cost & safety did. The need? Perfect fission to run safely + cheaply. Probable fix for this? Probably molten salt reactors. I ask, however, is this even doable?
@@gregbailey45 The insulation cannot completely avoid the loss of heat, but the hotter the surroundings the longer it takes. The heat in Tx (or in any environement that is not a volcanoe etc.) is s not nearly enough to keep the metal molten (imagine that !) we are talking 300 F or more as opposed to a hot summer day.
I've followed this technology for several years, but it is always nice to have another perspective. Thanks :-) One has to wonder why energy day-traders have not gotten into the grid storage game yet.
As long as it does not break ..... the layers separate themselves, you only lose one charge (and may not get much out of the battery when you would need it. But I doubt the disturbance would be that bad, that it upsets the layers a lot and if the earthquake is that strong it cracks the container, that is much more problems. Luckily there are lots of regsions where you do not have to expect heavy ! earthquakes. The container could be also placed on some shock absorbers.
Matt, Claiming solar and wind are “cost competitive, but battery storage is key” is Enron Pro Forma Accounting reinvented. You are excluding the two most expensive parts (intermittency and storage) of solar and wind to then claim they are cost competitive. They aren’t cost competitive in the least, which is why all the mental gymnastics are required in the first place. You have a responsibility to your audience to present the full context.
Isn't the real question is whether the required storage for renewables is so much more expensive than the peaker plants required for coal or nuclear that the ever lowering cost of producing power with solar/wind cannot make up the difference?
@@stevemickler452 The short answer is no, not even close. The battery storage required to power a modern economy would raise the cost of solar and wind by orders of magnitude…Which is why when Matt discusses cost, he only talks about fossil fuel dependent solar and wind.
@@lawsonhannah Extraordinary claim. Evidence? You do know about the Hornsdale wind farm right? Battery prices are falling toward $50.00/kw-hr. and you can save money today with solar/battery for your home v. buying electric power.
I probably need to do a video on just this aspect of energy storage. But costs for solar + battery are very competitive: www.energy-storage.news/news/bloombergnef-lcoe-of-battery-storage-has-fallen-faster-than-solar-or-wind-i
I love this channel. Ever consider staffing a comedy writer? Might help with those groan worthy moments and general appeal. They could also give some delivery and timing tips.
Actually, no. An internal short will increase the temperature, but not to the point of a phase change, so there's no explosion and the cell housing can easily handle the temperature rise. EDIT: It would leave the batteries discharged at the very moment they would be wanted to help deal with an emergency situation, though.
@@dmdeemer In a high voltage situation like that, the heat from the short will likely cause gas to form from the liquid in the cell. The cell will explode if that is the case. Never underestimate the power of a high voltage short.
If these things are really sensitive to being shaken then you would want to make sure that the facility storing them is also sufficiently earthquake resistant, which will add another cost to building.
When we talk about lithium ion batteries, we need to be critical of the CO2 footprint of their manufacture. This is the key reason we desperately need alternatives to Lithium battery chemistries, especially for grid scale storage
Beyound initial heating power requirements, it self maintains it idle and operating temps pretty easily. Motion sensitive at grid scale means tremors, earthquakes, meteor impacts...the worse reaction is a short and cool down. No fire. No explosion. No poison gas. Perfect solution. I hope the Ambri tean continues to improvecand grow. Awsome acheivement.
Beautiful, excellent. I like compressed air energy storage. Air is plenty and steel vessel plentyfull. I envision a big ship with a sail, underwater watermill (much smaller than a wind mill) A compressor drives air into floating steel pressure vessels. The pressure vessels can go autonomously to some facility to discharge the compressed air.
possibly stupid question.. if we're talking about grid scale .. why not have a huge well insulated tank with molten salt, which can be heated by energy suplus and used to run a turbine ran by water heated by the molten salt .. very huge energy storing potential and it produces AC not DC, so it can directly inject into the grid
I have had Ambri and Donald Sadoway on my radar for many years now. It's very promising to see them making more substantial progress in the form of medium scale test installations now. As you said, there won't be any single solution for a complex problem like energy storage. We'll need a healthy mix of different solutions for a sustainable future, but Ambri with their liquid metal battery seems to be a very likely candidate for short term energy storage and for grid-level load management.
there are many ways of storing energy.. gravity storage, inertial storage, heat storage (molten salts), pressure storage, chemical storage... but if you want to store electricity, the options narrow down a lot and things get a bit more costly and complex. Probably the most affordable and easier way for large storage capacity are *flow batteries*. This molten metal tech is also interesting, but seems a bit overcomplicated by comparison
It seems like the efficiency of these batteries would increase with use since maintaining a liquid state costs energy, they could be scaled up and buried with alternating charge/discharge cycles with the adjacent cells so that heat loss can be minimized.. Instead of a backup storage system they could be used all across the grid for cycle stabilization and efficiency, that would also allow any renewables to contribute to the grid from anywhere..
Why did AMBRI fail to deliver on promises for 2016, 2018..?? I know it's normal for new technologies to fail to deliver so early.. But if you could give details, much appreciate
Also Sodium is even more abundant than the mentioned Metals and NaS Batteries are a thing for quite a while now. I think the real problem is that, in the past,there was not really a market, for the type of energy storage we need for the Future.
Reading the Wikipedia, sodium-sulphur batteries have issues. The main difference is that Na-S used a solid electrolyte that degraded over time and the whole thing was corrosive and full of pure sodium (exposing that to air or water will result in a bad day) requiring a more complicated enclosure. Some of these issues will be shared with Ambri's batteries, but I assume that there's an improvement. Though only time will tell.
@@johnsmith34 well cycle stability is less of a concern for seasonal storage. Na-S Battaries are useless for private usage but I think pure Sodium can be stored savely in an indusriall envirement. The most limiting value in my eyes is price for roar material per MWh capacity. That makes Na look pretty good.
12:45 you neglected to mention that a sodium-potassium alloy Na-K is EXTREMELY REACTIVE to water. NA-K is much more reactive than Li-ion. Na-K is EXPLOSIVE on contact with water. Na-K has to be stored immersed in oil to prevent reaction with the water in the air.
You got me a little confused in the beginning, as I've never heard about "liquid metal battery". But yes, molten-salt battery is indeed one of the most advanced ideas and yes, it is being used already in several solar arrays. It's molten-salt battery, not molten metal. Yes, it's great for stationary applications.
Speed & scale (both in production & recycle phase) will solve everything, I think that is why Tesla is so focused on lithium Ion batteries. It is also most reactive to load changes.
I'm curious how this compares to the company that's making batteries out of shipping containers that are essentially salt water and iron. They've been around for a few years, but can't think of the name of them. But the battery they make is designed for large cap storage, and temperature wasn't supposed to be an issue.
There are actually a number of axes here that folks are not really hitting on. That said, the comments here that I read are quite astute. But the degrees of design freedom under consideration need to include: 1) The y = mx + b of scaling the technology 2) The availability of the materials and other economic uses of those materials (shadow prices)... that drive the value of the 'm' 3) The total amount of energy that such a system can store 4) The rate at which energy can be added or removed from the system, the dE/dt... 5) Latency and response time issues 6) Deep cycling issues (discussed, thank you...) 7) Design robustness / sensitivity to perturbations... how does a liquid metal battery deal with an 8.0 earthquake? 8) Whether or not the design is adiabatic or if not, what the heat is doing to the surrounding environment (there needs to be a Lagrange multiplier associated with any impact of this system on the local environment... look for 'Dantzig Wolfe Decomposition' on wikipedia) 9) MTBF / E[longevity] of the system 10) If there are any sensitivities to changing conditions in the environment. LIke not just earthquakes, but wildfires, snow, hail storms or whatever 11) Thermal stability, perhaps these are great for some deserts but not all. Or perhaps the performance becomes crappy in climates with cold winters 12) Is it possible for these liquid battery components to attack the walls of the containers they are in? Like having copper and steel pipes next to each other when water is running through the copper pipe? 13) Need to look at end-of-life issues and recycling of the components. All newly made systems need to be able to be reused / recovered losslessly... Or else humanity ends up a creek without a paddle.
Most high capacity/ Utility Scale storage has a serious KISSW factor. Simplre, Reliable and cheap and most techologies I see tend to fail that. The Sadoway battries tend to meet those requirements.
Molten Metal will be big in the future. Solar is best in warm regions, and Li-Ion that requires a ton of healing is really bad in those regions. Having a very large storage system at high temperatures, might also allow you, to recover some of the lost energy via a thermal power station. Its definitely warm enough for that.
I guess the less expansive way of energy storage would be: using a crane with a motor to lift heavy blocks up. For release of that energy stored would be to use the crane with a electric generator that would grab that heavy block and allow the gravity to pull the heavy block down that would spin the generator producing electricity.
you forgot mention that the melting point of Calcium is over 800C and that of antimony is over 600C. So a working cell will appear red-hot. You also did not say what is the size of the 1MWh cell stack; It will need 1ft thick insulation to maintain the temp above 800C. The real challenge will be the wires interconnecting the cells. And molten Ca can be really very corrosive.
sound like a good idea lit-ion is still the best on a small scale liquid metal would be the best if you need large capacity and fast reaction time (for power spikes) and liquid oxygen goes well with high capacity slow response time like storing power overnight
Speaking of cordless vacuums I bought an expensive Dyson cordless. It only runs for 3 minutes after a 12 hour charge and is really quite useless. I subsequently found thousands of people online were experiencing the same issue with their Dysons
Once perfected, I could see this being a great base load battery... I still think something like Solid State batteries for peak/impulse supply would be needed.
The High temp liquid metal storage batteries could provide ALL the heating needs for domestic water. It could also provide substantial support for HVAC heating if used with a heat pump.
this sounds better for the main powerplant to reduce the need for peaker plants. Energy storage on a longer scale like 2~3 week cycle time sounds more proper for sources like solar since rainy seasons will see the ignition of peaker plants with just a daily power storage.
but the main challenge remains: Seasonal energy storage. The problem is not, that the Sun does not shine at night. The Problem is, that it shines less in the winter. That does not sound as much of a problem, but run the numbers and you will sea, that every challenge of day to day energy storage is dwarfed by the problem of differences over the year.
@@nonec384 well we would talk about moving about 8 milliard people around. That is quite of an extreme measure. also I think that is an even greater challenge than finding a good solution for seasonal storage.
@@MusikCassette move the energy generation that is , i think it can alse be use to produce hydrogen that is co2 free and can be moved burned for energy or cars etc fuel
@@nonec384 hydrogen would be a propper solution for seasonal storrage (indipendent on where the energy is Produced) but it does come with its own bundle of challenges.
@@MusikCassette the hydrogen would be made more to bost the number in the winter season so there would less need to stock up on hydrogen that can also boost energy when there less sun on summer , or a nuclear or maybe fusion reactor
Not that I have anything really against this as a concept but would not flow batteries be better for base load storage? This sounds like it would be good for frequency stabilising because it wants cycling every day. Flow would be better for base load when the wind doesn't blow and the sun doesn't shine for days at a time as all you need to increase capacity is more storage tanks.
To solve the mobile vs stationary problem you just put it inside a spinning flywheel. The centrifugal force could be may times the shaking forces. Then make sure the flywheel never stops spinning. :-) Possible, but challenging.

I bought us a roborock s4, I think? It's honestly our favorite thing. Our kids make messes all the time and we wake up every morning to a clean floor. We nicknamed it "Dusty".
I prefer the carbon fiber wrapped flywheel battery over the liquid metal battery for grid storage.
I would suggest anyone interested in this battery tech go and watch Dr Sadoway talking about it. My favourite takeaway is his statement, "if you want it dirt cheap, make it from dirt".
ruclips.net/video/qXKxiSsIo_c/видео.html Advancing the Energy Revolution by Donald Sadoway
"Preferably, local dirt."
I have done so in the recent past after seeing another video on it but nothing was replied to me
Here's another one by Dr. Sadoway...he did at Stanford in 2016:
ruclips.net/video/pDxegcZqx_8/видео.html
He has been pitching his ideas (8+ years) for a long time and nothing has come of it. You can look at his old YT videos and see my comments from years ago asking when we will see this in production. It is always "a year or two away". Professors do "research" as a way to make extra money and we are talking big bucks. They have their undergrads and post grad researchers doing the work and they take piece of the grant money for the "advising" they do research.
I think people have to get away from the "one size fits all" approach. Stationary large battery banks for grid buffering, house batteries and vehicle batteries have different requirements. Drivetrain requirements are different for different vehicle classes etc. We should be open minded and develop the solutions that are most efficient for their use case.
@@contradictorycrow4327 Well it depends on what "Monopoly" or "Oligopoly" you talk. Why are all trucks diesel? Why is the default for individual mobility an automobile? Why is electric energy storage LiPo? one size fits all is not a sustainable answer.
@@TheCloudhopper But people like simple Questions and Answers. What is best is the most asked question and the Answer is treated like a religion. There is no place for "...for that specific purpose" in this question, as there is no place for a second good in Judaism and it's two big offsprings.
Of course there are different needs at different scales. Dr. Sadoway tossed out the idea of scaling up lithium ion batteries from iPhones right from the beginning. He started from a crisp sheet of blank paper with what he knew: electro-metallurgy. Ambri has the potential to hit one out of the ballpark with massive grid-scale power storage in a few years and leave li-ion stuck on first base with smartphones, vacuum cleaners, EVs and Powerwalls.
@@ub59 I am very encouraged, I saw a video where he was interviewed and was asking myself: when do they announce the next stage ? Looks like they still have funding, they have the test projects for 2022, and the tech is not _that_ complicated so that could work. 30 % or 50 % drop in costs for robust batteries - that would be a game changer. Not only do they cost less, they would also work much longer (not sure if that was factored into the calculation at 10:50). Never mind even if they broke it down to storage costs per kWh over 10 years .... 30 or 50 % less is huge.
That will speed up LARGE solar installation by people who have the space or want to invest in a community project. And the projects will be more viable while also reducing grid peak demand. (the large providers do not like that, they make more money with peak demand, some providers in Texas make ONLY profits because of A/C peaks in summer. The rest of the year they hang on.
Which explains why no one "voluntarily invests in winterization of the Texan electricity production.
Yep we need to , but cost scaling via capitlism and globalism dictate that a homogenous product is cheaper overall so we get square peg round whole solutions for the most part
That looks like a viable technology for large installation grid storage. Would be especially useful with solar arrays in desert environments. Nicely done video
Yeah, the abundance of solar radiation makes keeping things hot a lot easier.
You know what would also work for half the environmental impact?
A natural gas generator operating intermittently.
Utility scale storage has the potential to make everything much cleaner.
👍
It will more realistic combined to solar concentrators
@@southeasegirl2329 Yes, these plants are amazing, their hot molten salts can be used at night then reheated during the day, rinse and repeat.
I see great things ahead for liquid metal battery’s, and not just the main one you discussed today, but many different potential chemistries along the temperature gradient scale. This is very interesting technology and I pray that several of these can make it past the scaling issues and become useful as quickly as possible.
You didn't mention the biggest short-term challenge for Lithium-Ion: there's not enough production capacity for the necessary raw materials, and the producers might not be able to scale quickly enough.
Complementary technologies that use different raw materials are extremely important. Liquid metal batteries are particularly interesting because they tolerate (and even benefit from) high environmental temperatures. Most types of Lithium-Ion degrade quickly when used at high temperatures.
Unfortunately, the Ambri battery is in the very early stages of mass production. The first (and so far, only) planned project, the 250MWh battery in Reno, is planned to be delivered to the customer from 2021 through 2023. At that low, pilot scale production rate the technology is useless. If they can't scale production very rapidly it may never be economically competitive.
I always saw Reno as a way to show that it works. Seems to be metal cases stored in a small shipping container that hold the battery. The battery also go from a solid(discharged) to liquid (charged) so transportation is easier
You know lithium ion batteries come in many different forms. Lithium iron phosphate batteries kill everything. For home or grid scale storage Sodium may replace lithium one day. Then that's all that's needed until fusion can be achieved
@@tigertoo01 Yes, I know. But LFP, like all types of LIB still need battery-grade Lithium and Copper. Both of these could be scarce for a couple of years.
Sodium Ion might be a great alternative/complement if it materializes quickly enough.
@@w0ttheh3ll Agree that its not just a given there will be enough of anything but just looking at the current production and known reserves there is enough lithium for 100's of millions of EV's with a 60kwh battery. With Telephony and the internet merging and optical fibre and wireless communication becoming more main stream, Copper uses have reduced so the EV demand on copper is not as great as some believe. Still we will need a billion + EV's on the road. Unless autonomous driving becomes real and lives up to promises then the number of vehicles on the road may drop significantly. I think we should plough on with building EV's with current battery tech and hopefully it will lead to significant breakthroughs not only in battery storage but recycling too.
@@tigertoo01 I'm not saying there isn't enough stuff to dig up, just that there will be short-term shortages because not enough digging is happening right now.
Of course we should, and will, continue to build as many EVs as we can with the best tech we have available.

"most popular and widespread energy storage is Lithium ion"
That's just not true at all, pumped hydro beats it by a very large margin
Replacing “most popular” with “most popular for new installations” and “widespread” with “not geographically constrained” makes the statement true. He should be more accurate in word choice, and also explain in this video about grid scale energy storage the pluses and minuses of the major players, which MUST include pumped hydro, since it’s the clear leader in installed electrical energy storage in both GW and GWh comparisons.
@@altosack yeah, changing every thing false or inacurate in the statement makes it true...
You have pumped hydro in your house
Ideal for small neighbourhood storage system. Particularly in semi rural areas.
And large scale too
That’s a good point. You could have this in a little shed at the foot of a small road with, say, 10-20 houses. Maybe it’s saving up that same street’s solar and/or wind and supplying it back as well.
The sheer amount of work that we need to do in order to make mass energy storage viable just goes to show that we also need to be reducing our power dependence wherever possible. This means building denser cities so we can walk and bike everywhere and take advantage of shared surfaces in apartments to reduce heat loss/heat influx so less cooling and heating is needed.
I have been following Don Sadoway and this technology for about 5 years. Very impressive. I also love his Canadian sense of humour.
The heat might be an advantage in hot environments.
Agreed - augment this with heat pumps (say for keeping a datacenter cool) and it seems like a huge advantage
It could also be a good source for home heating systems, if charge and discharge cycles generate excess heat.
Makes no diffetence.
But in hot environment, it's unusable energy because it's in equilibrium with environment
@@destiny_02 Not at all true. One, if it is in equilibrium with its environment, that means it environment is literally so hot that it is melting, so unless you are in a volcano you are not going to be in equilibrium. Two, even if it was in equilibrium, that's not where the energy storage comes from. The energy is stored by the transfer of positive ions from one end to the other, not thermal energy.

Great technology for grid energy and would free up lithium ion cell production capacity for other critical sectors like transportation. These two sectors are the largest in terms of emissions.
I didn't really want to drink the oil, water, and syrup beverage either. Thanks for another great vid! Dave J
Good call 😜. Glad you enjoyed the video.
I've been waiting for more recent news about Ambri's work. I was concerned about their status, because their Wikipedia page talks about layoffs and reductions, but this is great news. For truly northern latitudes with truly brutal winters, these 'hot' batteries seem like a much better solution than lithium battery technology. That it has been done by this high-quality UwMF channel is just a bonus! Thank you!
Great video, as always! Addendum to deep-cycling Li-Ion batteries: If it's an Apple Ipad, deep cycling just a few times will kill it completely in a matter of weeks, forget about two years. Worst battery EVER. I had to get that off my chest. Thank you.
Best video so far on the liquid metal battery!
It's worth noting that Ambri is comparing their active material cost to LCO ($51/kWh), which is the most expensive lithium ion chemistry. LFP (Iron) is much cheaper at $8/kWh active material cost. Nickel will achieve ~$20k in the next few years - which is near Ambri's $16/kWh.
Furthermore: How much are the inactive material costs for Ambri? I'm assuming they require a lot of expensive thermal protection/insulation.
Also, what will happen to the cost of antimony if this technology is deployed around the world at scale?
Was excited about this tech ten years ago.
We should immediately ban all fossil fuels because this is the technology that is going to save the planet.

"That vaccuum is cool. How much is that?"
'$50 off with coupon' 😐
$500 price tag 😑
It's pricey, but it's pretty awesome. My wife has said that numerous times since we got it.
At first I was disappointed by only 37 reviews but other products from the same company have thousands of reviews so it appears worthy of consideration.
At that price I’d highly consider the Dyson product this is cloning tbh. I don’t have anything against product cloning but if you’re almost the same.. but anyway I’ve got an older one of this style, the Dyson one, it’s actually good enough to replace a plug-in upright vac if your place isn’t huge. So that’s nice for storage reasons in an apartment. This is a god use for the power delivery of lithium batteries, to get the suction, so I can see this becoming an increasingly common form factor.
@@UndecidedMF why would u but a manual vacuum when you can get a robot for same price??
@J Hemphill yes I know the attributes and flaws of a robot vacuum, and you need to supplement manually its losses. But when 90% of vacuuming can be automatically done, and once you own one you realise how much time you save. All I'm saying is I had to laugh at someone trying to selling me a manual vacuum. btw, my robot spot cleans, doesn't bumble, and also mops my floor, all while I'm at work, does an excellent job and saves me 35 mins of mindless manual labour per week. Look I get it, hes just advertising his free vacuum and who wouldn't. But if you've going to spend that much, get a robot, because you wont regret it.
The down sides in using liquid metal batteries are efficiency (80%) and charge leakage. On the positive side are potentially low cost, stability, and longevity. Ambri is a clear competitor to Tesla in the market of grid level storage. I wish them well in their ramp to production.
It seems like it is fundamentally a cost / maintenance question. It feels like the core components are good, but all the components that need to interact with them are questionable. Anode, cathode, whatever heater is used to heat it up when necessary, and the casing. Few materials seem like they would do well sitting in a molten metal bath.
And the failure modes if anything was punctured. But if the cost per VA is good and you have a stable installation it could be quite good. Less space than pumped water storage. Probably lower temperature than the molten salt designs for solar.
Ceramic casing and induction heating from the outside since its metal in the inside
One of the stories told by the developer is of a US military group came to see the molten batteries. The first military guy immediately says, “ what happens if this thing gets hit by gunfire ? “ the second says “ the molten metal cools as it exits the hole and plugs it “ . Number one says “ so the battery is self sealing “
I don’t think you would put a resistance heater in a metal bath, the metal bath would cause a short , the resistance elements would be outside the bath with some thermal path to the metal.
I'm so excited for this technology in my home state of Arizona! It just seems like such an elegant solution for our solar advantages! I hope this technology continues to develop.
A liquid metal battery is great for rural off-grid homes at the lowest cost and maintenance in the future.
They sound rather dangerous running at high temperatures. So, maybe good for large grid storage, but not so much for home use where home owners would have to maintain it themselves.
Here in south africa battery theft is a big issue. Mobile networks often have their tower batteries stolen. The network operators build serious steel cages, concrete barriers and many things to make it as hard as possible to steal... but they are still stolen. Some batteries are in the concrete itself to protect it.
Ambri!! Yeah, I always thought this was an excellent option for hot climates for grid storage.
For any climate!
@@gregbailey45 I only said that because I was thinking about the burning Tesla batteries in the desert.
Ha, I wrote a research paper on this at Uni and used his research as a reference. Fantastic to see this idea still going.
I get that this is intended for Grid level applications but It also seems like a good fit for home solar installations. Once installed, movement is also a non issue like for grid level energy storage and the deep cycling capability and projected reliability seem very compatible with solar installations on homes for off grid independence or emergency power during outages. Perhaps costs can become competitive in the near future for home use.
It needs to be cycled often to stay molten.
@@gregbailey45 so great for running the fridge, the stove, the AC, the heating (heat pump hopefully so roughly same electrical load as AC), the TV all day, etc etc
@@gregbailey45 In a home solar installation there would ideally be on average 12 hours of charge during the day and 12 hours of discharge after the sun goes down.
We need to convert gas stations to charging stations and use this type of tech to replace the holding tanks. Then the infrastructure for most cities will be properly engineered to be more renewable energy ready and sustainable. 3MW perstation would be appropriate storage.
Awesome explanation also Sodium Ion battery has been gaining popularity lately please give us a review.
It's on my list!
@@UndecidedMF - check out LiNa Energy (lina.energy/) - solid state sodium battery technology - abundant raw materials, cheap, high performance and safe! We'd love to inform a sodium battery review...
Your reminders that there isn’t one technology to rule them all is a good one as it is so easy to become convinced that one technology in particular must be the solution. Thanks again for your insights!
Thanks, interesting stuff. However, I plugging for aluminium ion. Compared to lithium ion have 3 times the capacity Durability not there yet but improving and looks promising
It's worth noting that the thermal management of these systems is not anywhere near as problematic as it may sound. Blacksmiths have been working iron since Roman times, and getting iron to forging temperature means getting it upwards of 1300 degrees Celsius. And that's a furnace you're actually working next to, putting stuff in and out of, and straight up hitting the thing you've just pulled out of it with a hammer. Getting a battery you set up and largely forget up to less than half that should not be difficult for modern engineers to design safe insulation for.
Thanks you! I really wanted to learn more about this tech
Glad it was helpful!
I think this is a GREAT idea! We need to allow the incremental changes toward solving our problems get us to full, democratized energy freedom. These batteries are scalable enough to allow a small town in the middle of Iowa to go off-grid (air-storage batteries as another example). These solutions allow the town or coop to determine their own needs without big companies forcing their weight on them. Thanks for highlighting these!!
I have been watching Don Sadoway for years, and am waiting patiently for Ambri to provide a home battery.
Being everything is liquid, no dendrites.
I would think baffles could make the battery earthquake resistant.
There was a recent fire of an electric car in an archway below a station in London. That caused mayhem and caused the train station to be shut and trains to be rerouted and cancelled. It just shows how bad they can be.
please make a video on the differences among of liquid metal battery vs solid state battery vs lithium ion battery
Probably a good video idea there. 👍
@@UndecidedMF And when you do, please do your research some other place than wikipedia.
@@HamRadio200 You haven't yet figured out the reality of global warming causing disruptive climate change, so you are not in a position to be critical of the research or sources of Matt.
@@xyzsame4081 In the past the earth was much warmer. Just do some research before you ask for a refill of the kool-aid.
I wish you had mentioned that the batteries maintain their own operating temperature through regular charge and discharge cycling. It is an important part of the conversation.
People seem to assume there is a need to keep them hot to keep them liquid where as they are able keep them selves hot through regular use.
Since it's based on a liquid, how scalable is it? Could you theoretically have one giant pool of 'liquid battery', or is there a limit to how large/small it can be?
I assume the distance between the anode and the cathode can't be too far, so this pool would have to be very long, but thin
This and "molten salt" batteries are better in multiple smaller cells than one big pool as the larger the cell the more difficult it is to keep a consistent temperature throughout.
It probably comes down to operability, many smaller cells are probably easier to transport/maintain than a huge single cell. More modular as well, so it'd be easier to scale up over time. And, if one fails and is somehow destroyed, the others can be relatively isolated thanks to their enclosure. So there's probably a sweetspot, and going bigger than that doesn't make much sense for safety and maintenance.
It's very scalable, but not by making one giant battery. It'd be racks and rows of the smaller batteries linked together.
@@Michelino_M5 The main advantage of being smaller is maintenance. Even if it was exactly the same efficiency at massive scale, operators would still choose smaller components that are strung together. If one little battery fails, you pull it out of the rack and lose a minuscule amount of power storage. If a massive battery fails, you may have to take a massive chunk, if not all, of the facility down for repair. And replacing an Olympic swimming pool of gallium is a lot harder than tossing a couple replacement units in a standard truck.
@@Beakerbite Yeah, that was the first thought that came to mind. But also consider how hard it would be to deploy such a huge pool of molten metal, from the factory to the site where it would be used.
I couldn't more highly recommend watching Donald Sadoway's MIT lectures on RUclips, on Solid-State Chemistry. He's the best teacher I've ever seen on the subject, hands down
I can't wait for the batteries installed in NV to prove themselves.
Hold your breath! Just wait for that one hot hot cloudy windless day. You'll be wishing you had a fossil fueled generation station near you.
If ambri ever goes public,I'd be buying some shares. This has great potential.
“No, one technology to rule them all, having options…” agree, yes, options, like nuclear power that should recognized as a strong player in the fight against fossil fuels.
I agree. Replace fossil fuels with a highly energy-dense and practical solution until we have the time to *experiment* with a less-dense source (which is what we are doing as the situation gets deeper)
Safety and co$ts. Hippies didn't kill fission, cost & safety did. The need? Perfect fission to run safely + cheaply. Probable fix for this? Probably molten salt reactors. I ask, however, is this even doable?
Finally, a technology that isn't just a novel way to push a turbine. The thermal to mechanical to electrical conversion losses are monsterous.
We need these in Texas…plus our heat can help with the molten state lol
Exyernal heat is not needed, and no advanyage.
@@gregbailey45it’s a joke
@@gregbailey45 The insulation cannot completely avoid the loss of heat, but the hotter the surroundings the longer it takes. The heat in Tx (or in any environement that is not a volcanoe etc.) is s not nearly enough to keep the metal molten (imagine that !) we are talking 300 F or more as opposed to a hot summer day.
I've followed this technology for several years, but it is always nice to have another perspective. Thanks :-)
One has to wonder why energy day-traders have not gotten into the grid storage game yet.
It was proven that Tesla lied about the sub 2 second speed.
Grid sized stirage is currently done using pump storage plants, which is very cheap in comparison and efficient
Great technology. Till an earthquake, then BOOM as everything mixes.
That's why they put it in nevada
As long as it does not break ..... the layers separate themselves, you only lose one charge (and may not get much out of the battery when you would need it. But I doubt the disturbance would be that bad, that it upsets the layers a lot and if the earthquake is that strong it cracks the container, that is much more problems.
Luckily there are lots of regsions where you do not have to expect heavy ! earthquakes.
The container could be also placed on some shock absorbers.
Matt,
Claiming solar and wind are “cost competitive, but battery storage is key” is Enron Pro Forma Accounting reinvented. You are excluding the two most expensive parts (intermittency and storage) of solar and wind to then claim they are cost competitive. They aren’t cost competitive in the least, which is why all the mental gymnastics are required in the first place. You have a responsibility to your audience to present the full context.
Isn't the real question is whether the required storage for renewables is so much more expensive than the peaker plants required for coal or nuclear that the ever lowering cost of producing power with solar/wind cannot make up the difference?
@@stevemickler452 The short answer is no, not even close. The battery storage required to power a modern economy would raise the cost of solar and wind by orders of magnitude…Which is why when Matt discusses cost, he only talks about fossil fuel dependent solar and wind.
You should make a video about that and post it here in RUclips.
@@lawsonhannah Extraordinary claim. Evidence? You do know about the Hornsdale wind farm right? Battery prices are falling toward $50.00/kw-hr. and you can save money today with solar/battery for your home v. buying electric power.
I probably need to do a video on just this aspect of energy storage. But costs for solar + battery are very competitive: www.energy-storage.news/news/bloombergnef-lcoe-of-battery-storage-has-fallen-faster-than-solar-or-wind-i
I love this channel. Ever consider staffing a comedy writer? Might help with those groan worthy moments and general appeal. They could also give some delivery and timing tips.
Under grid load, one good earthquake and KABOOM!
Wouldn’t anti-slosh baffles work?
Actually, no. An internal short will increase the temperature, but not to the point of a phase change, so there's no explosion and the cell housing can easily handle the temperature rise.
EDIT: It would leave the batteries discharged at the very moment they would be wanted to help deal with an emergency situation, though.
@@dmdeemer In a high voltage situation like that, the heat from the short will likely cause gas to form from the liquid in the cell. The cell will explode if that is the case. Never underestimate the power of a high voltage short.
If these things are really sensitive to being shaken then you would want to make sure that the facility storing them is also sufficiently earthquake resistant, which will add another cost to building.
When we talk about lithium ion batteries, we need to be critical of the CO2 footprint of their manufacture. This is the key reason we desperately need alternatives to Lithium battery chemistries, especially for grid scale storage
Beyound initial heating power requirements, it self maintains it idle and operating temps pretty easily. Motion sensitive at grid scale means tremors, earthquakes, meteor impacts...the worse reaction is a short and cool down. No fire. No explosion. No poison gas. Perfect solution. I hope the Ambri tean continues to improvecand grow. Awsome acheivement.
Earthquakes + liquid metal = rock and roll!
They would be filled to the brim, and if you have ever tried to shake a bottle of water that has nearly no air in it, it no longer sloshes around
Beautiful, excellent. I like compressed air energy storage. Air is plenty and steel vessel plentyfull. I envision a big ship with a sail, underwater watermill (much smaller than a wind mill) A compressor drives air into floating steel pressure vessels. The pressure vessels can go autonomously to some facility to discharge the compressed air.
A lot of moving parts for likely little energy
This sounds amazing from a maintenance, recycling, and reuse perspective.
possibly stupid question.. if we're talking about grid scale .. why not have a huge well insulated tank with molten salt, which can be heated by energy suplus and used to run a turbine ran by water heated by the molten salt .. very huge energy storing potential and it produces AC not DC, so it can directly inject into the grid
Three states of matter likewise three states of batteries but like food soft solids rule.
The technology looks well suited for large scale execution
I have had Ambri and Donald Sadoway on my radar for many years now. It's very promising to see them making more substantial progress in the form of medium scale test installations now. As you said, there won't be any single solution for a complex problem like energy storage. We'll need a healthy mix of different solutions for a sustainable future, but Ambri with their liquid metal battery seems to be a very likely candidate for short term energy storage and for grid-level load management.
there are many ways of storing energy.. gravity storage, inertial storage, heat storage (molten salts), pressure storage, chemical storage... but if you want to store electricity, the options narrow down a lot and things get a bit more costly and complex. Probably the most affordable and easier way for large storage capacity are *flow batteries*. This molten metal tech is also interesting, but seems a bit overcomplicated by comparison
It seems like the efficiency of these batteries would increase with use since maintaining a liquid state costs energy, they could be scaled up and buried with alternating charge/discharge cycles with the adjacent cells so that heat loss can be minimized.. Instead of a backup storage system they could be used all across the grid for cycle stabilization and efficiency, that would also allow any renewables to contribute to the grid from anywhere..
Why did AMBRI fail to deliver on promises for 2016, 2018..?? I know it's normal for new technologies to fail to deliver so early.. But if you could give details, much appreciate
Also Sodium is even more abundant than the mentioned Metals and NaS Batteries are a thing for quite a while now.
I think the real problem is that, in the past,there was not really a market, for the type of energy storage we need for the Future.
Reading the Wikipedia, sodium-sulphur batteries have issues. The main difference is that Na-S used a solid electrolyte that degraded over time and the whole thing was corrosive and full of pure sodium (exposing that to air or water will result in a bad day) requiring a more complicated enclosure. Some of these issues will be shared with Ambri's batteries, but I assume that there's an improvement. Though only time will tell.
@@johnsmith34 well cycle stability
is less of a concern for seasonal storage. Na-S Battaries are useless for private usage but I think pure Sodium can be stored savely in an indusriall envirement. The most limiting value in my eyes is price for roar material per MWh capacity. That makes Na look pretty good.
12:45 you neglected to mention that a sodium-potassium alloy Na-K is EXTREMELY REACTIVE to water. NA-K is much more reactive than Li-ion. Na-K is EXPLOSIVE on contact with water. Na-K has to be stored immersed in oil to prevent reaction with the water in the air.
You got me a little confused in the beginning, as I've never heard about "liquid metal battery". But yes, molten-salt battery is indeed one of the most advanced ideas and yes, it is being used already in several solar arrays. It's molten-salt battery, not molten metal. Yes, it's great for stationary applications.
Speed & scale (both in production & recycle phase) will solve everything, I think that is why Tesla is so focused on lithium Ion batteries. It is also most reactive to load changes.
I'm curious how this compares to the company that's making batteries out of shipping containers that are essentially salt water and iron.
They've been around for a few years, but can't think of the name of them. But the battery they make is designed for large cap storage, and temperature wasn't supposed to be an issue.
Always interesting to hear about new power storage and creation technologies. Thanks for the excellent video.
I would be curious to see your take on Flow Batteries for grid scale applications.
There are actually a number of axes here that folks are not really hitting on. That said, the comments here that I read are quite astute. But the degrees of design freedom under consideration need to include:
1) The y = mx + b of scaling the technology
2) The availability of the materials and other economic uses of those materials (shadow prices)... that drive the value of the 'm'
3) The total amount of energy that such a system can store
4) The rate at which energy can be added or removed from the system, the dE/dt...
5) Latency and response time issues
6) Deep cycling issues (discussed, thank you...)
7) Design robustness / sensitivity to perturbations... how does a liquid metal battery deal with an 8.0 earthquake?
8) Whether or not the design is adiabatic or if not, what the heat is doing to the surrounding environment (there needs to be a Lagrange multiplier associated with any impact of this system on the local environment... look for 'Dantzig Wolfe Decomposition' on wikipedia)
9) MTBF / E[longevity] of the system
10) If there are any sensitivities to changing conditions in the environment. LIke not just earthquakes, but wildfires, snow, hail storms or whatever
11) Thermal stability, perhaps these are great for some deserts but not all. Or perhaps the performance becomes crappy in climates with cold winters
12) Is it possible for these liquid battery components to attack the walls of the containers they are in? Like having copper and steel pipes next to each other when water is running through the copper pipe?
13) Need to look at end-of-life issues and recycling of the components. All newly made systems need to be able to be reused / recovered losslessly... Or else humanity ends up a creek without a paddle.
Most high capacity/ Utility Scale storage has a serious KISSW factor. Simplre, Reliable and cheap and most techologies I see tend to fail that. The Sadoway battries tend to meet those requirements.
Water stored optimally at higher altitudes can be most affordable for storing electricity and water.
Wake up to a new video. Also need to get ready for my online class. I choose the new undecided video.
Ha!
Molten Metal will be big in the future. Solar is best in warm regions, and Li-Ion that requires a ton of healing is really bad in those regions.
Having a very large storage system at high temperatures, might also allow you, to recover some of the lost energy via a thermal power station. Its definitely warm enough for that.
I guess the less expansive way of energy storage would be: using a crane with a motor to lift heavy blocks up. For release of that energy stored would be to use the crane with a electric generator that would grab that heavy block and allow the gravity to pull the heavy block down that would spin the generator producing electricity.
you forgot mention that the melting point of Calcium is over 800C and that of antimony is over 600C. So a working cell will appear red-hot. You also did not say what is the size of the 1MWh cell stack; It will need 1ft thick insulation to maintain the temp above 800C. The real challenge will be the wires interconnecting the cells. And molten Ca can be really very corrosive.
sound like a good idea
lit-ion is still the best on a small scale
liquid metal would be the best if you need large capacity and fast reaction time (for power spikes)
and liquid oxygen goes well with high capacity slow response time like storing power overnight
The effective efficiency of lithium is closer to 80-85% when taking into account the DC to AC conversion, no?
Which does not impact any other battery technology, right?
Speaking of cordless vacuums I bought an expensive Dyson cordless. It only runs for 3 minutes after a 12 hour charge and is really quite useless. I subsequently found thousands of people online were experiencing the same issue with their Dysons
Stationary storage usually don't require a small footprint .
I see no problem with low power density solutions
Once perfected, I could see this being a great base load battery... I still think something like Solid State batteries for peak/impulse supply would be needed.
The High temp liquid metal storage batteries could provide ALL the heating needs for domestic water. It could also provide substantial support for HVAC heating if used with a heat pump.
The NaK electrode may be low temperature in operation but it's pyrophoric and would need to be chilled for transport.
this sounds better for the main powerplant to reduce the need for peaker plants.
Energy storage on a longer scale like 2~3 week cycle time sounds more proper for sources like solar since rainy seasons will see the ignition of peaker plants with just a daily power storage.
Small modula reactors could be used to power the batteries so the power could be more stable than renewables which depend on wind or solar.
but the main challenge remains: Seasonal energy storage. The problem is not, that the Sun does not shine at night. The Problem is, that it shines less in the winter. That does not sound as much of a problem, but run the numbers and you will sea, that every challenge of day to day energy storage is dwarfed by the problem of differences over the year.
it never becomes winte in the ecuador so just move closer to it
@@nonec384 well we would talk about moving about 8 milliard people around. That is quite of an extreme measure. also I think that is an even greater challenge than finding a good solution for seasonal storage.
@@MusikCassette move the energy generation that is , i think it can alse be use to produce hydrogen that is co2 free and can be moved burned for energy or cars etc fuel
@@nonec384 hydrogen would be a propper solution for seasonal storrage (indipendent on where the energy is Produced) but it does come with its own bundle of challenges.
@@MusikCassette the hydrogen would be made more to bost the number in the winter season so there would less need to stock up on hydrogen that can also boost energy when there less sun on summer , or a nuclear or maybe fusion reactor
Not that I have anything really against this as a concept but would not flow batteries be better for base load storage? This sounds like it would be good for frequency stabilising because it wants cycling every day. Flow would be better for base load when the wind doesn't blow and the sun doesn't shine for days at a time as all you need to increase capacity is more storage tanks.
am interested in this tech for a rural, off grid home - could it be scaled appropriately to individual homes that are using solar panels and such?
I think that will take quite a while. And because of the heat required it needs insulation and some limits on the minimum size to be efficient.
There is also Flow batteries like redflow that loves deep cycling and are already being put in place around the world.
To solve the mobile vs stationary problem you just put it inside a spinning flywheel. The centrifugal force could be may times the shaking forces. Then make sure the flywheel never stops spinning. :-) Possible, but challenging.
