If you’re going to drive a fuel cell car, you need a way to carry around all that hydrogen. Currently, that’s done with big, bullet-proof gas canisters. But metal organic frameworks (MOFs) could someday be more efficient storage solutions. We talked about MOFs in our recent video on extracting gold from seawater: ruclips.net/video/j5eomDz4Z0E/видео.html
nice that was one of my questions. Pure H2 somehow brings some negaitve associations with it. Hindenburg Images sit deep even if containment procedures improved since then . Gotta have a look at that video than
One could use Armonía. It would contain even more H2 than H2 itself compared by volume. Also a German university created a gel like substance what could store H2 cheap and sustainable. One would then fuel the care with water and separately that paste. Interestingly, they claim that if one extracts the H2 from that paste actually H2 (from the water) is created as "waste" in addition. So one gets more H2 out of that paste than one stored in it. Which is also a brilliant way to lower H2 production costs. -- sadly I haven't heart anything new about Armonía or that H2-paste lately.
Just started looking at this subject and I found that you covered a large array of topics very succinctly making it easy to understand and consume. Thank you very much.
I wasn't expecting that fan to start up so quickly and spin so quickly as well! Very nice. Sure it used up all the hydrogen, but there wasn't very much to begin with, and at the power level shown it makes sense that it was used up fast!
Great video as always! Really engaging and with the right amount of detail to help understand the topic while still going straight to the point. Personally, exactly as I wouldn't give up on hydrogen even though (as for now) much of it is made from steam reforming, I also wouldn't give up on carbon as an energy carrier; I really hope that projects like Eni's Ecofining (hydrogenating oils up to actual green diesel) take off (as processes they go with a single reaction straight from biomass to fuel, so they are also quite energy efficient), but maybe some breakthroughs in mass oil production (like algal oil mass production) are still needed to render carbon-neutral carbon-based fuels an economically viable option!
This was super helpful to me, I'm into electronics and know quite a bit but I guess hydrogen fuel cells just passed me by. I never paid any attention to them thinking they were out of my realm of obtainability. I never knew I could just buy a small one to play around with and this was a very good in depth introduction 🤙
Learn that the center of a magnet is by far the most powerful part!! Just as it separates N and S it can also do much more. If VIBRATED at the correct frequency it can separate the H2O
I work for a transportation agency as part of a group researching our future fleet (alt fuel busses). Fuel cells have very appealing traits, but from the perspective of building out infrastructure, this technology has a lot of maturing to do. A transit agency using this to power a fleet would need either very convenient hydrogen stations nearby (3rd party operated), or the agency would have to build out infrastructure to make their own fuel. That raises questions about mission creep for a transit agency's role and quite a few sunk costs for safety provisions alone. Keep in mind as well, compressed natural gas busses must be re-certified by a qualified 3rd party before returning to service for any collisions over 4-5mph. I'd imagine similar safety requirements for vehicles carrying compressed hydrogen. That's just one more drop in the bucket where fuel cells' impressive initial features are 'watered' down in real world operating conditions.
Love your explanation and I feel like there are definitely optimizations we can do to make it efficient for hydrogen fuel cell unlike how a lot of people are being downers at Toyota investing into hydrogen without understanding. I like how you broke down the cost of producing and transporting hydrogen but if we could make those efficient, i think the future is looking amazing.
Great video. It's easier for regulatory agencies to stay on top of power plants than individual vehicles. Also in power plants we can capture / filter/ scrub pollution's from the plants much easier than individual combustion engines. Electric, hydrogen electric, renewable fuels like biodiesel are all what's needed. We have areas in the US the naturally exhausts a ton of hydrocarbon gas, might as well use it to produce power then to just have it gas off into our atmosphere. All in all leaving the O&G to shift it's focus into power or newable fuel generation is the absolutely correct thing we should have been doing decades ago instead of trying to immediately replace them. Especially with the fear of losing our hydroelectric dams in the water states of US.
I agree with you for most of it except for bio fuels. They are a scam! Seriously they are not eco family due to how much it takes to grow the corn. From water, to nutrients to the land it requires. It just isn't efficient or a good use of our resources even if they burn cleaner. There are better options overall.
The efficiency of the power plant is true but what she did not mention is that there are considerable transmission and distribution losses from electrical power plants. Their efficiency and a car’s efficiency wind up being about the same. Excellent video none the less!
This is a great video. I am in the auto supply industry and heavily involved in electrification. We are also tracking Hydrogen, as it will be more sustainable for long haul trucking. I would love to see a similar video breaking down the true carbon footprint and effect on the earth that EV is creating. We seem to only be looking at zero emission output from the vehicle, but ignore the impact on the front end.
WOW! I had no clue what the Hydrogen Fuel Cell looked like. Thank you. This video is the first! I thought it was these big contraptions where you feed it H; which probably would be case for "big projects" like a car ... But that small gadget you are holding can fit in my electric seated scooter...
I wonder... Have I ever watched a better explanatory video on any subject than this video??? I don't think so. At least, I don't remember one. Thank you for the amazing video!
Please more hydrogen fuel cell content!!! As methane is a greenhouse gas itself, are the CO2 emissions of the conversion process to H2 less than just burning the methane? If so, it could actually be an amazing tool to allow governments to convert gradually (ie. build bulk hydrogen fuel cell infrastructure, and supply it with H2 produced via methane conversion, but gradually convert your H2 production to solar/electrolysis and bio-production over time).
@@zoltanbognar5960 Electrical currents can also produce hydrogen and oxygen in water directly using a anode hooked to a electrical source. Now the big question would be if you say used a 16 gallon tank of water to produce the hydrogen to power the fuel cell how long would it take to use up the water in the tank if you were driving a hydrogen powered car?
I will call captain planet and Sue u 😂 if hydrogen become big just joking because hydrogen car produce nitrogen which is not good for ecosystem and rain acid rain will kill us either way both r not good but rather acid nitrogen is not good
Great Video, don't worry about the existing way we use H² clean ways are available and are scaling up rapidly. It will all be made using 100% Green methods eventually. This will take time but none the less we are finally heading in the right direction to 100% Green which is the ultimate goal! Renewable resources are growing everyday. Thanks for such a fun and great learning video.
The importance of hydrogen fuel cell is not just to make it cleaner; it is a very good power source. One day we will invent new sustainable methods of hydrogen production.
Very clear lecture! Question though: why not using the electricity produced from the solar panel to charge car batteries ? Is it less efficient than a fuel cell?
Another good outcome of replacing combustion engine cars with hydrogen fuel cell cars that wasn't mentioned could be reduced vehicle pollution within cities --> better health outcomes and quality of life. Maybe the future is to switch all shorter distance city driving to EV/hydrogen, but we keep combustion vehicles for long haul transportation. Thanks for the super informative video, in just 8 minutes you answered most of the questions I came with! Also loved the demo!
How much does that fuel cell cost? How many Watts were consumed when powering the fan? Given an infinite supply of hydrogen and oxygen, how long will that fuel cell last?
Hydrogen could probably bootstrap itself through grid-scale storage projects. The nature of storing hydrogen and the purity requirements for the fuel cell are something that wouldn't really matter a lot at a power plant (just another thing they have to monitor and control), but those requirements are a pain in a mobile application like in a car!
By pumping oxygen into oil wells we can oxidize the crude and separate hydrogen from carbon while its still in the ground. The hydrogen can be extracted through a filter and mineral ions can be added to the carbon dioxide to create a solid carbonate that just stays in the ground. Does anybody have any ideas to get rid of some billion dollar oil refineries?
How was your solar panel made and how will you dispose of it at end of life? How do you refine the materials for your battery , how do you dispose of the battery, how long does the battery last and how do you make the electricity to charge your battery right now.
EV batteries are recyclable, and there is plenty of lithium in the world. Making green hydrogen, and hydrogen fuel cells are much less efficient than just charging a battery with the same electricity. Hydrogen cars are electric cars, using a battery and motor for regen and even out the output of the fuel cell. Basically they are a terrible idea, with the only advantage being faster refuel time. Batteries being developed cut that advantage way down.
What a great video! I just found out about the Toyota Mirai and became interested. It uses a fuel cell, but I can't find why it can't be used in reverse, plugging it into the mains to produce hydrogen overnight. Anybody know more?
Added cost & weight to vehicle, added complexity and low efficiency vs industrially produced hydrogen. You can make oxygen at home technically very easy, look up "hho generator"
@ACSReactions, which pem has been used in your fuel cell ? I worked on Fuel cell in my University, will be happy to see more detailed video of fuel cell component kinetics.
It'd be added weight and complexity, but I wonder if it'd be viable to just build a closed loop hydrolysis system INSIDE the car that runs off of electric car chargers. You'd lose the refueling speed benefit, but you'd gain the benefit of a vastly greater network to refuel from. The extra weight might reduce your range a bit, and you may need to top up the electrolyte and water occasionally, but I think as long as the complexity and weight isn't too much it'd be a viable way to do hydrogen fuel cell cars.
This is a great video, I would love to learn your view on the lifetime carbon impact of the production of an electric vs hydrogen vs traditional combustion vs PEHV I have seen videos and articles claiming that if you take into account manufacturing and recycling costs traditional combustion and PEHV are the best over their lifetime. Electric being the worst? I have no opinion or data on this, would love to hear more information on this topic that is unbiased.
Hydrogen could simply be made at any hydro electric dam like James bay or Hoover dam through electrolysis. The hydrogen could then be sent through an additional cables system with the existing infrastructure of the power lines than sold to hydrogen stations at gas stations or to individual houses for profit for the power plants and then taxed for the Government.
Does the fuel cell contain iridium and platinum? If so, would scaling this technology be possible with the availability of these exceptionally rare metals? If this is a real problem, would it really help if the hydrogen was "greener"?
Looks at clear liquid: "Oh, I can tell that hydrogen is going into this container and oxygen is going into this other container". Her ability to see molecules is amazing, lets disect her and study her retinas.
Designing a wet or dry cell, U must make them, perform, in it own area. So to do this, it must have the most area, of surfaces, and facing the right way.
So you are going to need to depressureize it constantly, or use low pressure = less torque. In the event the depressureizers get clogged/fail, you want a backup, because if the hydrogen goes past a certain temperature, 50 molecules = 3 mile blast radius, and what you would be using is a lot more than 50 molecules
I am a hydrologist and I will say she is spot on with everything within her video outside of the concept , admittedly unspoken, that natural gas is dirty. Natural gas is actually extremely clean and is the cleanest of all fossil fuel types which is why it is used so heavily within the industry. Hydrogen cars compared to electric cars within all supply chains considered , electric cars are very “dirty “ especially through the mining process and still using gas to produce the electricity at every fill up. Hydrogen technology has greater potential to be cleaner throughout the entire process
I just purchased a Mirai and I believe that the future is going to catch up with Hydrogen cars as it has done with other forms of energy for cars. Gas cars are on the way out and hydrogen and battery cars are the way in. I know it's not perfect at this time, but it is going in the correct direction. Gas cars have been around for over 120 years, hydrogen cars for about 7 years. Think where it can be given enough time and development.
If we used nuclear and fuel cells it would be golden. Huge problem with electric cars is that the electric grid is really inefficient. A lot of electricity is lost from resistance in the lines. If u are just simply using fossil fuels then my geuss would be it's more energy efficient to just run gas cars... But smaller more scale reactors and this storage tech would be a great solution
4:02 "...natural gas is reacted with high pressure steam..." The process actually favors low pressure. Low pressure gives higher conversion. Take a look at Le Chatelier's principle.
Hydrogen fuel cell cars don’t have a water reservoir, they have a hydrogen gas tank and an air intake Otherwise the water would need to first be broken down into hydrogen and oxygen before they can be used for power generation, which itself requires power usage and kinda defeats the point
pretty girl explaining some cool science 😊 it'll be interesting to see what they develope in the next 20 years as far as making these sorts of processes more efficient!
There are electric cars that use H/O fuel cells, as a battery, then there are internal combustion engines, that burn H2, usually stored in a metal hydride.
Ok here is a thought .Electric car takes several hours to fully charge and burn it rather quickly and must be charged to continue to travel . Hydrogen car takes seconds to fuel from station and can be fueled while driving if set up to do so .1 takes a very heavy load off the grid while the other puts a heavy load on a grid that is heavly loaded, now what makes more since. Just a thought, what will you do when a governor tells you not to charge your car do to an overload on the grid.
The problem with Hydrolysis is that it requires scarce and expensive materials, like platinum, but in theory, we could use nuclear reactors to directly power Iodine-Sulfur Cycle, then mixing this Hydrogen (Called Red Hydrogen) with atmospheric Nitrogen to industrially produce Ammonia through the Haber-Bosch Cycle (Called Red Ammonia), which can be mixed with water and easily transported there where it's needed, like metallurgical, chemical and fertilizers industries, seaports, airports, land transport terminals, and so on... That's what we call a Red Ammonia Energy Matrix... I'm actually working in an investigation project to simplify this Matrix and someday scale it up to industrial level, hopefully.....
yup, one method I know is by converting CO2 into CH4 (methanation), which is then the fuel used to generate electricity or produce heat. There are some companies that already make use of this technology.
Take a petrol generator with 110v and 240v output, from the 110v connect an invertor to use for the electrolysis cell to produce hydrogen/oxygen for the generator which can then run for free to produce 240v.
@@jamesvandamme7786 You obviously missed the point of what I stated. It starts on petrol then starts producing hydrogen/oxygen by its electrical output, the petrol is used up but continues to run on the gas it produces. A buck converter would be ideal for this.
@@merlin1346 So, burn petrol in an engine, drive a generator that makes 240 VAC, feed an AC to DC power supply (with an ideal buck converter), run an electrolyzer to make hydrogen, then feed a fuel cell to make DC, then an inverter to make 240 volts AC? OK, now what kind of efficiency do you expect out of this?
I am a huge fan of hydrogen energy, and I appreciate how you explained its operation in the first part of the video. However, I would like to point out that the second part of the video contains some inaccuracies and misconceptions. There are methods to convert plastic waste, car tires, and other organic waste (from the oil industry) into hydrogen energy using a closed-loop process called Pyrolysis. If done correctly, this process will not harm the environment since there are no byproducts that are released into the air. Your video is a “fly in the ointment” since it takes a great concept and makes it look bad. Pyrolysis can convert oil spills or any products from fossil fuels into green energy using “Green Way” technology. This technology exists, but some corporations may want to create confusion around this great concept. Finally, we need to concentrate our resources on storing H2 in dry cells instead of liquid, this will resolve the storage issue and make it more convenient. As well as releasing it to the public.
Electrolysis process generate Oxygen along with Hydrogen. This hydrogen can be a source of fuel in power generation but what do we do with Oxygen produced?
A little off subject, why are we farming corn with diesel fueled equipment and then fermenting the corn which produces co2 as a byproduct. Then cooking it with energy to distill it to get the ethanol . Then we burn it with gasoline to save the environment
There is a membrane that is permeable to cations (positive ions), in this case H+, the positive hydrogen ion, but not to negative ions or neutral molecules. It's called a proton exchange membrane. When an electric charge is placed on the cell it splits the water and pulls the H+ ions through the membrane, reduces them (gives them electrons), and there is your H2 molecules. Using them for electrolysis is really running them in reverse, and I'm honestly not sure about the details, but that's the gist of it.
If you’re going to drive a fuel cell car, you need a way to carry around all that hydrogen. Currently, that’s done with big, bullet-proof gas canisters. But metal organic frameworks (MOFs) could someday be more efficient storage solutions. We talked about MOFs in our recent video on extracting gold from seawater:

What about mining the gas Giants for hydrogen
Metal hydrides shouldnt be so expensive, but still weighs less than a battery im sure. Hydrogen is the future

Hydrogen cars compared to electric cars within all supply chains considered , electric cars are very “dirty “ especially through the mining process and still using gas to produce the electricity at every fill up. Hydrogen technology has greater potential to be cleaner throughout the entire process
Why is anode negative and cathode positive? Arent they supposed to be the other way around?
Yep
How was it that the hydrogen remained in beaker (and didn't escape) as you disconnected the solar panel to connect the dc motor?
Thanks; liked & subscribed;
»»»»»that immersion of 2 electrodes directly from the solar panels into water to get the H and O2 may be interesting..
You have to compare apples to apples. What is the C02 release for battery production?
I just purchased a Mirai and I believe that the future is going to catch up with Hydrogen cars as it has done with other forms of energy for cars. Gas cars are on the way out and hydrogen and battery cars are the way in. I know it's not perfect at this time, but it is going in the correct direction. Gas cars have been around for over 120 years, hydrogen cars for about 7 years. Think where it can be given enough time and development.
how exactly do the protons power the electric motor? What happened there? Thanks!
Thanks for the video. I like to ketchup on renewable sauces.
Alright-I loled
If we used nuclear and fuel cells it would be golden. Huge problem with electric cars is that the electric grid is really inefficient. A lot of electricity is lost from resistance in the lines. If u are just simply using fossil fuels then my geuss would be it's more energy efficient to just run gas cars... But smaller more scale reactors and this storage tech would be a great solution
4:02 "...natural gas is reacted with high pressure steam..." The process actually favors low pressure. Low pressure gives higher conversion. Take a look at Le Chatelier's principle.
Great video! Thank you.
Why couldn't the water vapor that's produced go right back into where you're extracting Hydrogen from?!?! Like a closed loop?
Hydrogen fuel cell cars don’t have a water reservoir, they have a hydrogen gas tank and an air intake
Otherwise the water would need to first be broken down into hydrogen and oxygen before they can be used for power generation, which itself requires power usage and kinda defeats the point
Can you give us a like to where we can buy the tiny fues cell? What power can it output?
Av no idea how i ended up here but love it
Meanwhile. nuclear electrolysis is sitting over there in the corner just like uh bros hi
pretty girl explaining some cool science 😊 it'll be interesting to see what they develope in the next 20 years as far as making these sorts of processes more efficient!
I don't know if there's any reasons not to but why not use geothermal methods or heat from open volcanoes?
Very informative!
Why do the positively charged protons flow through the membrane to the positively charged cathode?
I would think electric motors are much more efficient than a reciprocating piston engine. This looks promising.
Charging a battery is much more efficient than electrolysis. So, no, it's not promising for EVs. Might find a niche somewhere.
Can you guys go a video on lithium mining and rare earth metals in general?
There are electric cars that use H/O fuel cells, as a battery, then there are internal combustion engines, that burn H2, usually stored in a metal hydride.
Ok here is a thought .Electric car takes several hours to fully charge and burn it rather quickly and must be charged to continue to travel . Hydrogen car takes seconds to fuel from station and can be fueled while driving if set up to do so .1 takes a very heavy load off the grid while the other puts a heavy load on a grid that is heavly loaded, now what makes more since. Just a thought, what will you do when a governor tells you not to charge your car do to an overload on the grid.
The problem with Hydrolysis is that it requires scarce and expensive materials, like platinum, but in theory, we could use nuclear reactors to directly power Iodine-Sulfur Cycle, then mixing this Hydrogen (Called Red Hydrogen) with atmospheric Nitrogen to industrially produce Ammonia through the Haber-Bosch Cycle (Called Red Ammonia), which can be mixed with water and easily transported there where it's needed, like metallurgical, chemical and fertilizers industries, seaports, airports, land transport terminals, and so on... That's what we call a Red Ammonia Energy Matrix... I'm actually working in an investigation project to simplify this Matrix and someday scale it up to industrial level, hopefully.....
can we use CO2 to make energy?
yup, one method I know is by converting CO2 into CH4 (methanation), which is then the fuel used to generate electricity or produce heat. There are some companies that already make use of this technology.
Take a petrol generator with 110v and 240v output, from the 110v connect an invertor to use for the electrolysis cell to produce hydrogen/oxygen for the generator which can then run for free to produce 240v.
As long as you steal petrol from somebody's gas tank, yeah, it's free.
@@jamesvandamme7786 You obviously missed the point of what I stated. It starts on petrol then starts producing hydrogen/oxygen by its electrical output, the petrol is used up but continues to run on the gas it produces. A buck converter would be ideal for this.
@@merlin1346 So, burn petrol in an engine, drive a generator that makes 240 VAC, feed an AC to DC power supply (with an ideal buck converter), run an electrolyzer to make hydrogen, then feed a fuel cell to make DC, then an inverter to make 240 volts AC?
OK, now what kind of efficiency do you expect out of this?
I am a huge fan of hydrogen energy, and I appreciate how you explained its operation in the first part of the video. However, I would like to point out that the second part of the video contains some inaccuracies and misconceptions.
There are methods to convert plastic waste, car tires, and other organic waste (from the oil industry) into hydrogen energy using a closed-loop process called Pyrolysis. If done correctly, this process will not harm the environment since there are no byproducts that are released into the air.
Your video is a “fly in the ointment” since it takes a great concept and makes it look bad. Pyrolysis can convert oil spills or any products from fossil fuels into green energy using “Green Way” technology. This technology exists, but some corporations may want to create confusion around this great concept.
Finally, we need to concentrate our resources on storing H2 in dry cells instead of liquid, this will resolve the storage issue and make it more convenient. As well as releasing it to the public.
Real science……. Thank you
"A hydrogen fuel cell is a lot like a sandwich." Actually, a hydrogen fuel cell is a lot more like a battery.
A fuel cell stack is also more like lasagna than a sandwich.
Electrolysis process generate Oxygen along with Hydrogen. This hydrogen can be a source of fuel in power generation but what do we do with Oxygen produced?
Thanks, very factual.
How much does this fuel cells cost?
And how much energy (in KWH) is produced from 1 kg of hydrogen.
This sounds perfect for stuff like wind and solar which arnt as reliable you can stockpile hydrogen and use it as needed
This helped me Alot!
A little off subject, why are we farming corn with diesel fueled equipment and then fermenting the corn which produces co2 as a byproduct. Then cooking it with energy to distill it to get the ethanol . Then we burn it with gasoline to save the environment
Hi could please send me the link of the fuel cell your using here as i desperately need it for conducting an experiment
Here is a question. At the point where the water is split into the two gasses how are the two gasses separated and sent to different sides?
There is a membrane that is permeable to cations (positive ions), in this case H+, the positive hydrogen ion, but not to negative ions or neutral molecules. It's called a proton exchange membrane. When an electric charge is placed on the cell it splits the water and pulls the H+ ions through the membrane, reduces them (gives them electrons), and there is your H2 molecules. Using them for electrolysis is really running them in reverse, and I'm honestly not sure about the details, but that's the gist of it.
