It probably isn't a game-changer, but having a diverse set of competing energy storage technologies can only be a good thing.
at 1/10th the cost it is a game changer.
Adoption will take time.
@@lunatik9696 1/10th is a claim, not a reality. Well, I can guarantee you that it isn't 1/10th. The physical storage medium itself is only 1/3 of the equation. The other two big pieces are the megawatt-scale electronics and whatever the ongoing maintenance costs wind up being.
I would take a lesson from metal hydride hydrogen storage and fuel cell systems. The biggest cost is not the storage medium, but everything else required to make it work.
Same thing with chemical battery storage systems. A LFP battery and all related components are solid state. The same isn't true for hydrogen, fuel cell, flow batteries... or iron-air.
I would also note that in the Video, iron-air was compared against lithium-ion, NOT lithium-iron-phosphate which is much cheaper. He talked about nickel and cobalt, for example.... LFP batteries have neither.
Even if it is traditional batteries keep getting cheaper and better capacity. So by the time this ramps up 10x cheaper may just be a few times cheaper.
If it isn't a game changer, but is a good thing, then it will be a good thing until cost efficiency is not there because another product offers more savings. We are at a point when various products offer similar solution but time will tell what's most viable long term.
Yeah...but Sam mentioned Texas - and its retarded leaders disconnected the state grid from the federal grid as well as they didn't winterize renewables on purpose. Even without renewables they could have gotten electricity easily from the surrounding states.
I've been pushing for iron-air for last few years, writing to the gov't etc. The Queensland University of Technology iron-air project also needs our support. It is a technology that is IDEAL for the Australian grid.
Renewables were the last thing to go out on the Texas grid, especially wind turbines. There are a lot of videos on it.
If you want to make something dirt cheap, make it from dirt. I’ve been excited about iron-air batteries since i first heard of them. If the efficiency is good, they could solve a lot of problems.
...if...I hate speculation.
@@thyristo some are more educated and likely than others.
That's how research works.
The thing is that the efficiency can be rubbish, but if the cost is low enough they make a lot of sense for storing excess energy, which is basically free. This is the opposite of the current development of highly efficient/ light batteries for cars etc.
@@markthomasson5077 Yes, absolutely. I suspect we’re going to wind up with a power storage model that looks a lot like how cache memory works in a computer. There will be small caches of expensive, high speed storage, then increasingly slower but less expensive backups.
@@markthomasson5077I have read the efficiency is around 60%. Yes, it is excess energy that would be wasted but why not just split water, combine it with carbon dioxide, and then have a truly long term energy system.
Q: Who is 'Green Washing'?
A: Southern Company / GA Power.
Sam, I live in GA and GA.Power., and its parent company (So.Co.) have no interest in moving forward.
If you research this claim you'll find that they are actively holding back any and all progress to help reduce their captive ratepayers from benefiting from home solar.
Thanks for all you do.
Cheers
Stay blessed sam all my prayers for your spouse...
Thanks for keeping it real and providing great programming.
Glad you enjoy it!
thanks for the update on your wifes health man. I hope things will be better
Your daily doses of "game-changing" battery tech.
Have you noticed whether any games have actually changed?
3last week 3before last
When are these games coming into play? 2028 ? That’s often what happens to these promising technologies … a bit like Nuclear Fusion Generation …
😂😂
Its happening the trouble is no one seems to care
Been waiting for this. It always seemed a promising alternative for stationary storage.
On a slightly smaller scale this equates to a 5KW discharge rate and 500KWH capacity system. I wonder if the footprint of that would fit under a typical house. It would be great to have a built in 4 day electrical storage capacity for the roof top solar.
Tryin to get that put into th code as we speak
Based on your capacity description, I'd characterize this as a pilot scale facility.
The delay in building anything in the 🇺🇸 is due to regulation. In about half of 🇺🇸 states (e.g. Texas) regulations are being intentionally restructured against renewables in favor of fossil generation.
The same Republicans that are every hour every day talking against regulation and red tape.
Hypochrites as usual.
look at who finances the politicians election and you will find the petroleum industry.
Sad but true …….th deeply entringed heavily subsidized gas and oil companies are not going down w/outta fight
………..to kill as many people brain cells spreading th most noxious air as greedily possible with Mississippi legislators in their back pocket!!!
Is the electorate in Texas completely stupid? Are the legislators ideological morons? Remember it only took one religious nutter to put the entire Islamic world into reverse for a thousand years. Check it out!
What happened in Texas was a complete grid failure due to the power companies not wanting to winterize their systems. Nat gas, nukes and coal power plants froze over while renewables were taking the brunt of the energy demand and couldn't sustain power output.
I agree, there was no lack of wind in Texas, the wind turbines just froze up due to not being winterized.
Well gee that doesn't sound like Texas at all... there is absolutely zero corruption in Texas, they are as pure as the driven snow... oops!
These batteries seem to offer good pricing, engineering simplicity and safety all of which are important goals for a competitive big battery storage system.
But there are other important goals that go to the dynamics of a viable energy storage system. Multi-day dispatch of stored energy is great but it suggests a technical shortcoming. Controlled slow despatch of electrical charge is possible most likely because that is what Iron-Air batteries lend themselves to. Rapid dispatch of great amounts of power either isn't an available technical option or it must instead be achieved by the massive scale of storage rather than the technical attributes of the batteries per se. Iron-Air will need to be supplemented by other faster storage and despatch battery technologies.
I think I heard the same. Say there is a power outage, the other batteries can respond real time. Oh, that plant is out due to damage for a week, this kind can kick in. Still probably using the other kind as well.
But the costs have to be compared per Kwh.
What is the energy cost density factor?
Stationary storage
I am going to think of it as "Phase-Change-Storage". May not be correct, but gets one thinking about all the ways to collect "work" now... and burn it later. As simple as lifting a huge weight into the air, then letting it into a controlled fall, or pumping water up to a storage tank for later use. Melting wax in a barrel, or anything that harnesses the magic of changing form (like Solid to Liquid to Gas). Think about how efficient mini-split heat exchangers are. ... Major innovations are lurking in the corners. Most are not well known because they disrupt profit.
The Viking landed @ Melbourne Intl. airport just 30 minutes before estimated time after a flight of around 7300 km.
Well done!
For an extremely low 'source impedance' (a term in electronics, in electrics, it might be expressed differently) capacitor banks can be added to the mix. This would provide a 'peak' or 'surge' supply much greater than a slower discharge bank. The downside to capacitor supply is the short term of storage, the upside is for that short-term, supply can be massive. Think their use as nuclear detonators, and photoflash supply, albeit they can last for longer durations when used in bulk.
Together with iron-air and lithium-X, a more modest bank can appear much larger than it is in terms of long-term supply to satisfy transient and peak supply.
Irion-air batteries are not really a new idea. There are also zinc-air batteries that work much the same. You let oxygen turn a metal into an oxide to get the energy out and then use electrical power and chemistry to reduce the material back into a metal form. It is a good idea for storage if you can make it work because one side of the chemistry doesn't need to be stored.
All the variety of battery options is so confusing. I think I should hold onto my Diesel Merc for another year or two until the "winning" battery emerges.
All winners because solar is dc voltage
These batteries are not for use in cars.
There will “always” be new formulations coming; just a matter of when what is available in the cars at the moment is good enough 😀
You have a deep knowledge of everything. Amazing video
It will be using a former steel plant site. The big deal with this is 100 hour battery not 2 or 4 hour batteries. So it can supply for longer expected needs. If it works China will build 10 by the time we build a second one.
Probably more like 100 to 1, LOL.....and sell them at half the price!
50% is a milestone and evidence that you can go 50% again... my thoughts with you and your family Sam... it's curable, it's possible, have faith... and congratulations and best wishes... ( I had to go through 30 intros to find out what was going on with you and your family... thanks for sharing...) '; p
This battery may be cheap as dirt, but it takes a lot of it to be useful. The footprint of this technology is on the large side. Zinc-bromine (like Red Flow) takes up half the space for the same performance.
You are correct, these batteries need to be paired with lithium ion. They complement each other. Lithium ion is great for grid stability, iron-air and flow batteries are great for longevity. We need both.
Now Georgia has the right idea to have long term clean renewable energy sources
At this point, it's becoming irresponsible for companies to continue developing lithium-based stationary energy storage solutions. Lithium should be reserved for mobile applications such as cars, trucks, and airplanes. Stationary applications should be using sodium, iron, or other cheap and plentiful materials.
What does 100 hr get you, 100 hr of how many kwh or gwh or how many homes? I think projects like this are great but it would also make a lot of sense for utilities to be selling/installing a power wall type of system in every new building project at minimum and trying to sell/retrofit to all existing ones.
What is round trip efficiency? From Google it seems about 60 percent which is 95 percent for Li ion batteries.
At these ranges one should just split water and combine it with carbon dioxide to create a long term fuel storage option.
@@waywardgeologist2520 Power to hydrogen is 85 percent efficient, hydrogen to methan is 70 percent, methane back to power is 50 percent. You get roundtrip efficiency of 30-35 percent. Just use Li ion battery with nat gas peakers for longer term fluctuations. That is best option by far
The problem in Texas was nothing was built for cold snowy weather. Even the nuclear power plant shut down. Simply a case where regulations needed to have requir the grid to be built with the worse in mind.
Thx Sam, I learn so much from this channel!
Interesting as all get out
Happy to hear that!
Southern Company has has long generated power with a conventional mix of fossil, hydro and nuclear units, but has used energy storage systems (like pumped hydro) for quite a while to offset the expensive and less efficient running of peaking units. Of late, I heard that SoCo has committed to a strategy that is moving them toward carbon neutral generation and they have been dabbling in Solar and Wind. I'm encourage that SoCo seems to be going big into battery storage, as that is a critical tool to compensate for the variation inherent in wind and solar generation (as well as variation in load). I'm sure if SoCo determines that the batteries are cost effective, the PSC and any other regulatory bodies (FERC,NERC,SERC, etc) that could potentially interfere with deployment will get on board.
Reducing smog an carbon level of atmosphere
Actual data from Form Energy: $1-10 per kWh (I guess they use raw iron sand). It will supply 100 hours of power ( meaning 5 full days of backup, I guess there is a natural discharge rate giving that number? Or it is just an example and you could have as many days you want). A 10GWh battery can supply a 100MW.
Where did you get that number for 3kwh per m3. Iron air battery have theoretical densities of 1.2kwh per kg. So that comes to more than 1200 kwh per m3. Care to show a source?
Thanks for the important information that Sam should include in his videos to dramatically improve the value for his viewers...
@@Klargus Lol my bad (I will correct my statement, thanks), I was in bed reading without glasses. Thought I saw kWh but it was only kW. Data was from a presentation by "Reinventing the Iron-Air Battery for the Electric Grid" on youtube.
@@DarylOster Sorry I made a mistake, have corrected comment now. Disappointing the company can't just clearly tell us the real kWh/kg and kW/L values.
A lot of work going on in the metal air battery space.
A problem with iron is low cell voltage so batteries are very large.
Calcium and aluminium air look more promising for compact storage devices but also have problems requiring resolution.
Aluminium air in particular is looking promising for use in light aircraft where it could provide three to four hours operation. The fuel would be in the form of a cartridge of aluminium metal that would be replaced at refuelling stops.
Cost savings hopefully will incentivize innovation with this type of chemistry

It DEFINITELY is a game changer! I have shared on Sam's videos before the research report that only 50% of available roof space needs to be covered with solar cells to produce 100%of ALL energy usage world-wide. Continuity is the only remaining stumbling block. In jus a few years, every new home will have a 100-hour Iron-Air battery and solar - possibly some of the new, small wind turbines to top it off - AND WE CAN THEN ALL GET OFF THE GRID! Keep the grid around for once-a-year backup power, but - no coal plants needed for the small requirement, and no new power plants needed! Older homes will also find Iron-Air batteries affordable, along with solar cells, which continue to drop in price. FOOTNOTE: Texas drops in output from renewables during the blackout - was way smaller than fossil fuel electricity losses - by 10 Gigawatts! Propaganda against wind was so blatantly lying pervert poop, I'm surprised we were ever subjected to lies that awful.
How does this battery technology stack up against iron flow battery?
Form energy batteries can they be exposed to weather like I’m on property line they have all the solar panels I’d like it be connected to the grid
There is more scalable redux flow batteries potential looming. In the end scalability can be reached in so many ways that claiming one or another is just to early to tell without good understanding. And maybe it can differ per country based on specific parameters even.
But happy that multiple solutions are investigated :-)
Biggest draw-back of iron-air batteries is round trip efficiency of 50%, although this may not matter in many applications.
Lastly, how about giving us info on the characteristics of these batteries. Longevity, ability to use all the rated power and so forth. And is there any plans for them to manufacture home batteries.
Curtailing energy into gravity battery ???
Supposed to last a lot of cycles if properly designed, but you probably would not want them, as their performance for home would be poor and need to be paired with fast batteries anyway. They are slow to charge, slow to discharge (can only rust and in-rust so fast) and low round-trip efficiency. Large-scale installations are what they are good for.
Will form, energy or Iron air batteries be for consumers to or just commercial
Good information
Please somebody who knows better correct me if I'm wrong; but ..
Round-Trip Efficiency is 50%.
Cost is good, eventually $50/Kwh capacity but dunno what these georgia utility guys pay.
I can't help thinking that Sodium-Ion tec is not much more expensive, and 90+% RTE.
Also, if you can tolerate 50% RTE, why not do electrolysis and store huge tanks of hydrogen for months - inter-seasonal. The Fuel-Cell conversion back to electric releases huge - nearly 50% - heat (which can be sold), but then so does this Form Energy system.
Thanks and best wishes!
Many thanks!
Could consumers purchase from Solar companies
Bedankt
State officials including Republican governor Greg Abbott initially blamed the 2021 Texas freeze outages on frozen wind turbines and solar panels. Data showed that failure to winterize power sources, like wind turbines and natural gas infrastructure, had caused the grid failure. Texas's power grid has long been separate from the two major national grids to avoid federal oversight, though it is still connected to the other national grids and Mexico's; the limited number of ties made it difficult for the state to import electricity from other states during the crisis. Deregulation of its electricity market beginning in the 1990s resulted in competition in wholesale electricity prices, but also cost cutting for contingency preparation. Would have been easy for Texas to prepare and to get electricity from the surrounding states or the "United States of America". 🤦
Wow 👌 amazing
I’ve never heard of rust changing to metal plus oxygen. But it must work.
Yes it can be done and alo has potential for electrochemical conversion of iron ore to metallic iron, doing away with costly, polluting blast furnaces.
As always the trick lies in the detail of how to do it efficiently and sustainably. Those finding the solution stand to make a lot of money.
Fantastic
I’m still not convinced of this company in Gibraltar
Buteful video
omg another game changing battery , so much choice out there ! ...oh .
Is this the concept that has the silicon anode with the nano enhanced surface?
The U.S. has a permitting problem because our overall grid is too old and there are many fossil fuel companies paying off politicians to delay or prevent adoption.
If I were going to combine Iron-Air batteries with LiFePhosphate, I'd use the IronAir to continually recharge the LFP, which would have the power density to handle peak demand and get topped up during the night. If this one battery can provide 15 Mw, then two can provide double that. Given all the advantages of this technology, especially the abundance of the materials, there is no excuse, not to roll these out at a truly massive scale. Now!
Charging one battery from another is the height of stupidity. Loses are the only result
@@MegaWilderness If Li ion batteries are 85-90% round trip efficient and an Iron-air battery costs one tenth the price, I think that anything which allows you to reduce the expensive Li aspect of your battery storage, can only improve the levellised cost of storage. Energy losses (in my humble opinion) are not the most important aspect of any storage system. Basically, because electricity generation from renewables, is getting so, so cheap and storage is the eternal bugbear.
Might be this is a good solution. For long time however there are stationary Redox-Flow-Batteries that perform quite well also in Australia. Are there comparisons between the systems already. However seemingly we have already enough technology but by big oil corrupted governments and politicians try all to block the use of these technologies by all means. E.g. in some cases there are still heavy regulation problems when you want to get independent from big grid. There is e.g. the PICEA system from Berlin that with about 25 square meters of PV can produce hydrogen to store in standard low pressure bottles. Here in middle-Europe by June/July you have enough for hard wintertime. But by August till October weather can be quite well and you have energy to sell or store redundantly in powerwalls. But also for heating a pool in autumn and of course fill your EVs. There are so many possibilities and the small system in the size of a refrigerator can easily scaled up for bigger houses needing more power. The investment is rather small and can come down when production is ramped up; today it makes your PV, HP, Heating and Cooling concept about 60‘000 USD/EUR more expensive. PICEA‘s process heat of course can be used too. There are quite no limits to design the optimized concept for any house in any region. I therefore think that more intelligent people who can afford to pay a little more should go ‚all in‘ to become FREE and independent from any energy company or only use excess when it’s offered cheaply, e.g. Tesla in Texas offering night wind energy at 30 USD per month. Also should we think intelligent small local grids, e.g. young people in Pakistan that developed simple nets for poor people helping them investing in PV and selling excess energy or getting some back with a simple computer like the basic PC Arduino. We need more adapted technologies for people and not more big business stealing from customers for the believe that they provide energy. But think, who cares when you are FREE and have your own energies made available individually. Sure that not everybody is in a perfect situation but those who are should take action and responsibility NOW! Climat changes today are really since industrialization men made and that is no joke of scientist. However the way to accept and change realities is hypocritical as we mostly get pressure from governments where they can easily make money without addressing the innate cause and effect. They always follow they money and go and teach the easiest way. The hidden agenda is make people dependent like drug dealers and pimps do that. So people should start thinking on themselves and check all their energy possibilities!🤔🤓🇨🇭
Iron is the cheapest most abundant metal. It's pennies a pound. If we make and scale batteries with it then costs will be as low as possible.
that is how all batteries work. It isnt strange at all.
Hi Sam
So glad things are improving for your wife
There are some really good RUclips doctors who discuss diet and cancer
There is also a Ted talk show where the guy says that eating a certain mushroom cured his mother of terminal cancer
With iron-air there's no need for LFP. With lower power, you just need more of them
Awesome 👏
Thank you! Cheers!
Honestly 'we' did think of doing this before. It's pretty much exactly what we're doing with the battery technology that is hydrogen, allthough with horrible efficiency.
Another game changer: airbags on the outside of cars in order to dampen impacts with other vehicles and people.
big car manfucaturers wont allow it, it eats into their bottom line of selling cars every year with minimal updates
@@hardkore360ZF already works on it.
A couple of things don't make sense. You (and others) talk about 4 hour batteries. Surly if in 4 hours you only used half of the power in your batteries, some time later - next day for instance - you would have the rest of the power available to use. Then you talk about the Fe - O batteries not being able to deliver large amounts of power. Surly you just connect more batteries in parallel. The amount of amperage you can draw increases with the number of batteries. For greater voltage, you connect these groups of batteries which are in parallel, in series with each other.
Other stationary batteris are cheaper than existing power generation... This one is on par with existing power generation, making it more expensive than existing options..?
Is Europe behind in giga battery storage and why or did I just miss the news?
Nice
there is no such thing as change everything. it always comes with trade offs. if you ask me why, I simply don't know. that's just the way it is.
Beautiful lovely ❤❤
I'm interested
Sounds great
How many cycles will it last?
Theoretically infinite. Iron-Air batteries have been in use since Edison stole the idea. Not enough energy density for transportstion other than on Locomotives as a back-up system. Not for EVs, just stationary power storage.
Lovely
problem is the iron turns into iron oxide and the reaction stops like the aluminium air battery
Well they have a way to reverse the oxidization to recharge, as he said I in the video. Rust to release charge, charge to remove the rust to store energy.
Yeah, that’s kinda how they work. You charge it by reversing the iron oxide reaction. It’s not fundamentally different than the chemical reaction in any other chemical battery.
Compared to peaker plants they are much cheaper and can be deplyed in smaller unit around a region allowing better and cheaper distribution. This of course goes against central control and current power providers wishes so you have one potential area of pushback. Secondly the financing for this is coming from those very same types, central control oligarchs and fuel and commodites companies who like the idea of controlling consumable products. It is the ultimate industry
How many charging cycles will they last compared to LFP? How is the cost compared to sodium ion?
And, it’s the software that makes megapacks or powerwalls unique.
How about the Bezos’ batteries?

lol Iron in Lithium Ion, :D nice :)
batteries aint cheap.Quote"The popular idea that we can use mostly or only solar/wind with sufficient battery backup is… economically absurd. Batteries are so expensive that just 3 days of global backup using Elon Musk’s Megapacks would cost $590T, about 6X global GDP"
So, what's the projected cost and cycle life for the Fe-Air battery, and how does it compare with the LiFePO4 and other alternatives?
Costs are projected to be 10% of lithium alternatives. Cycle life is almost immaterial as they can replenish with more iron pellets cheaply and easily.
The downside is size. Energy density is very low. But they are for stationary applications, especially solar farms where they can be placed under the panels.
@@johnb7430 Can you please provide a source that supports your statements about the cost being 10% of tge LiFePO4 alternative, given the LiFePO4 cell alternative is currently thought to be less than $70/kWh?

More volume
Sam: With all the "game-changing" tech announcements we encounter weekly, it's wise to be both intrigued and skeptical about all claims. Of course battery tech will keep improving; density will increase and prices fall. But who knows what the ultimate form will be, if there is such a thing? Just a caution about over-enthusiastic statements.
You said batteries sustained some spot for days; this is rarely done. You can look at it as - how long could you sustain a 500sq ft home on electricity alone, heating cooling, cooking, hot water. A 21 kWh Powerwall can sustain a small home running everything; for 2-3 days for just a couple. 8 kWh per day; not of course including charging a car, if you did - that might cover 1-2 days depending on commute. Want to power a city of 1 million multiply by 1 million - that is 21 Gigawhats; 1 Billion is 21 Tarawatts and 4 billion is 82 Tara watts - double or triple if you want all cars to be EVs. The Georgia Iron air battery is only 15 Mw - or enough for about 1000 homes for 2-3 days. Hence you'd need about 1 million of these JUST to power homes for 2-3 days not including industry and not including EVs - if you needed to also cove EVs and Industry - multiply but at least 5 - 5 Million such sites. Cost $200 million each? $10 Trillion would get you 2-3 days of power storage; not power; now you have to make 100x as many wind miles and solar farms - No problem a couple hundred trillion and this all sounds good for a couple days ; oh better plan for a week? OK 200 Trillion or so.. no problem just print it up ;).
👍👍👍👍👍

I read that they were aiming for 20 usd / kwh. If you take that number and calculate the 15MW/1500 Mwh it would be equal to a 15MW/60MW Tesla Megapack setup. So same money just 25x longer stories.
OK if you can get cheap land to house them but in some locations the cost of the land could outweigh the saving on the cost of the batteries.
Sam, dont get hard feelings about our regulations and permits. At least most of the time, they are helping to keep our water and air clean, our people safe and the environment overall protected. I remember the 70s when the air you say you dont like in Thailand was over most of our large cities. After the EPA (started amazingly by Nixon of all people) was established, things got a lot better. As for iron air, if i had the choice it seems like LiFeO4 would be better with its higher output.
The one thing I don't get is what do you mean by 100 hr. storage . That doesn't sound like a very long time
The 100 hour charge-discharge time is a big disadvantage. It needs to be cheaper to make up for this drawback.
Not really, you just have to make it bigger. If the battery is the size of 100MWh, there is still an out or input power of 1MW, that is the powerdraw of 100 households.
Massive and cheap are not compatible. 15mw is nothing
Omg..I’m so sorry about your wife’s condition…have you tried Rick simpsons oil?
Don’t tell me - this …………………..
It's a redox reaction...NiMH & Lead Acid batteries already do that....
