This will be great for off road (and I mean reeeeeally off road) routes, especially high up mountain passes. Refilling these hydrogen tanks can happen monthly, but how easy would it be to transport it there. It will double as a water station 😁😄
You wouldn't want to drink that water. If water is 100% pure it will pull minerals out of your body when it passes through you. You can get really sick. You'd have to mineralize it.
I have been very skeptical of hydrogen lately, but I can see that this could be useful. Still expensive to make and still a by-product of refineries for the most parts.
@@brushlessmotoring I'm hearing hydrogen and natural gas is a good mixture. It can safely transport through pipeline. With all the talk of GM and Ford working on new v8 engines. I could see a future of mobil recharging stations.
Interesting but $1/kwh was a bit painful to hear. I pay $0.11/kwh and I'm starting to see many DC fast charging stations lower prices to $0.28-$0.30/kwh. That's a good 10x more than home use and 3-4x more expensive than some fast chargers. I still only see hydrogen being a real value for long haul trucks myself.
Probably a good solution for military applications also, just need a clean water source (portable well drill?) and some rapid deployment solar panels, the base then has a means of producing it's own fuel for trucks/humvees, tanks, forward operating aircraft, fuel cells or Karno generators for electricity at night, no more being fuel constrained.

so, the concept is that you make the hydrogen from water using green power. The "hydrogen economy" doesn't involve fossil fuels.

Yes, you're sacrificing some energy efficiency, but you gain that long duration capability. Here in California, we generate significantly more solar than we need, but we haven't built enough storage for it to last us through the night. We have the largest battery system in the world, but it's still only 6 GWh; the goal is 53 GWh by 2050, but at the present rate, we'll have that in about seven years.

Greetings from southern Ontario Canada I really enjoyed the video i have put down a deposit for the chevy blazer ev 1LT and according to the Canadian website i known exactly when i will see it in my driveway
For almost 30 years we’ve been going down the wrong road! It’s always been hydrogen!!!! Imagine where we’d be if we’d put all the R&D into going hydrogen instead of electric cars?!?
It's not through lack of trying or investment, its the sheer physics of the problem that hold hydrogen back. It's only use now, is to distract and delay the public from EVs - the goal is not to get you into a hydrogen car, it's to keep you in a gasoline one. Truth be told, the investment in EVs has been lacking, not hydrogen. NASA spent billions in today's money on it, Toyota has sunk their entire reputation and future on it, but it just doesn't work as well as a battery - on every measurable quality - even filling time, when you average out ALL fills and mark charging an EV at work, home or hotel as the 10 seconds it takes to plug in and walk away, vs. the 5 to 10 minutes you spend every 200 miles filling a hydrogen car - and that's assuming no line up or hydrogen shortages. PEM Fuel Cells are an efficiency breakthrough that took us to the moon in late 1960's, auto manufacturers have been trying to make them make sense in a vehicle ever since, but if you want green hydrogen, the losses from the electrolysis and fuel cell combined give you back less than 33% of the electricity you put in, that's why it's so expensive, and will always be at least 3 times as expensive per mile than an EV.
Toyota has thrown a lot of r&d money at hydrogen, but there's a fundamental economics problem that they aren't going to be able to solve with any amount of technological advances.
@@AlRoderick The big problem Toyota had that Tesla solved was the filling station problem. Even if they had a system where all you did was hook up a garden hose to a filter in the car and plug it in at home to power an onboard electrolyser to fill up with H2 that would have been a better system. Then there are sealing problems, needing an electrolyte fluid fill for the electrolysis process, changing out said purification (most likely RO filter) and things get very complex very quickly. The battery solution is pretty decent for a commuting appliance, especially with the convenience of home or work charging. Still think the best solution for people who have a place to plug in daily is a PHEV though, at least until we get more battery factories and mines up and running. The generator is underutilized if ever used that much, modern fuels and lubricants are much more stable for longer storage lives, ICE tech has gotten to the point where it rarely has problems (it's usually the electronic gizmos that go wrong in cars these days), and modern batteries can take the abuse of many cycles, at least well past the time people typically keep their cars these days.
That was a great interview, definitely not "soft ball". Roman knows his sh*t (well, except for the "3-phase DC" comment) and this guy had to be on his toes. Good job!
reminds me of the interview to be Qualified in Submarines, except there's three people interviewing you, two of whom have specific training on the nuclear reactor (one is an officer, to a submarine warfare officer you need one year of calculus one year of physics using calculus, so basically you need a STEM degree), and they can ask you literally anything about the boat from the weight of the diesel to what kind of nuclear fuel we use. Officer and enlisted have the learn the same things (in the context of getting qualified). They'll have you draw the Trim and Drain system (how we move water around the boat), then say a fire has started and you have to not only walk them through how one would fight the fire, but show how water would move around on the diagram. It's a stressful interview, of course the whole thing is stressful duty....lol 🙂 The officer said he was impressed with my knowledge of the nuclear reactor, given that I was not a nuclear tech (I was a sonar tech). 🙂 Don't mind me I just felt nostalgic for a moment lol
Amazing. These could be put all over Wyoming and Montana without local power needs. They could fill fuel cell and evs. And heck sell the water to RVs coming through
It seems like it is much more difficult to generate H2 gas than to generate electricity from solar or wind, etc. Splitting water through electrolysis, for example, is very energy intensive. I think that the advantage of hauling H2 instead of a giant battery pack is energy density. But it seems like there may be more loss from doing this than from having a fuel cell vehicle. With this it does the extra step of converting from H2 to electricity, then storing that electricity in the EV's battery, plus the energy to haul the equipment. Sure, fuel cell vehicles have small batteries, but I think that is more to do regenerative braking, etc.
What they always fail to tell you is that hydrogen cost more than three time as much for the same distance in electricity. 95% of the worlds hydrogen production is grey hydrogen which is from methane reformation, coincidentally producing large amounts of greenhouse gasses. Not only super cost effective but also great for the environment.
Grey. Blue supposedly captures most of the carbon, but is not successful at scale. Most hydrogen is grey (methane) or black (coal) and emits all it's CO2 into the atmosphere.
- no that was included, this was touted as experimental proof of concept, not an economic solution - Diesel gensets are the current grid isolated solution to generate electricity in the absence of a solar or wind array..
@@kadmow Porsche’s battery truck for charging 10 Taycan’s at once at 350kW is an interesting solution too - obviously can’t be refilled in the same way this can, but a fleet of them being trucked to renewable charging and back to sites would also work. I doubt they are cheap either.
So charge your EV with fuel. How novel. Maybe natural gas, diesel or gasoline too? Maybe just start with a vehicle that uses fuel and skip the whole EV part? There are some significant losses with the switching back and forth. The amount of losses, back-end costs and infrastructure that goes into keeping these EVs running is mind boggling.
EVs are easy, we have electric most places. It's the power distribution that is problematic. More energy is coming from rural areas with solar and wind. Need more battery storage and high voltage transmission lines.
Actually .... EVs are very cheap to fuel directly from gird connected renewables. Charging stations are cheap as chips to add, and AC chargers are very cheap, an overnight fill is fine for a lot of use cases including the majority daily driving we all do. Don't conflate the complexity and cost of hydrogen with EVs - they have very little to do with each other. You can fill an EV from a Diesel generator if you have to, and that emits less CO2 per mile than a diesel combustion engine does due to the efficiency of the generator and the EV combined. (Bloke in the Australian outback did it as a test). This looks an awful lot like GM trying to avoid writing off their hydrogen costs as a complete loss. Something Toyota will eventually have to do too.
@@jghall00 - all the cars plugged into the grid most of the time will be the batteries everybody is looking for - every carpark will have a charge point at every bay at some eutopian point, those don't need to be very fast to recharge for the few miles of typical commute - then the houses can suck down whatever energy they need overnight (if the wind doesn't blow, while the sun doesn't shine) - leaving the next day to rinse and repeat. (Some time between now and 2050 we will actually sort out all the energy balances to see if there is any net reduction in pollution - or if bulk nuclear economies will offset the emissions im the places without nuclear.)
Pure Oxygen actually does not burn. If it did everytime you lit a match the world would burn up. 😂 That is why we need gasoline etc fire needs fuel and oxygen.
The temporary site thing is probably the only use for this. Hope United Rentals, Sunbelt, etc. all get a few of these to move around the country for disaster relief.
JCB has a loadall, backhoe and excavator running hydrogen. Also have a genset running hydrogen. Anything running their JCB 4.4L engine can essentially be a near future hydrogen build.
This seems backwards or behind the times to me. They already have cars and stations that fill cars up with Hydrogen, then the cars convert the Hydrogen into electric. I guess this idea will be obsolete in a very short amount of time. Either charging stations will pop up to replace this or further out we will have hydrogen / electric cars everywhere.
I wonder if there is a realistic way to produce hydrogen at remote sites using solar or wind and electrolysis. If that were the case, this would have real potential essentially solving the intermittent problem we have with wind and solar. Since about 95% of the hydrogen produced these days is with steam methane reforming, I'm not sure I see the point. Why not just have a generator that runs off propane or natural gas if the total emissions are similar to those resulting from producing the hydrogen? Are there actual plans to expand production of "green" hydrogen?
You make a good point on the propane generator, if the hydrogen is grey (as most is), hydrogen is worse on CO2e per kWh, and propane is a lot easier to handle, and you can bring far more energy onsite in the same space. (Source EIA - US Electrical Generation) Propane 0.97lb per kWh - 439g per kWh. Grey hydrogen, 9 to 12 kg CO2 per kg of H2, at 14.5kWh per kg, 620g to 830g per kWh through a fuel cell. The problem with renewables going via hydrogen is you lose 66% of the input electricity, better to use a battery for multi-day storage, or overbuy on vehicles so you can have some charging while using others - most fleets have surplus vehicles to account for servicing downtime, a mix of wind and solar gives a somewhat consistent supply, and you may get overnight charging which is more useful, wind can break down though, being mechanical.
How do you figure? This truck has a 450 mile range- so $200 for 450 miles, thats over 44 cents/mile. My gas F150 will go over 600 miles on a 36 gallon tank- at $3.50/ gallon thats $126 for 600 miles, or 21 cents per mile.
I would think it would have great applications for disaster areas, to counter all those naysayers who say you could not charge your car if the grid is down due to a disaster.
Propane gen-sets already fill this need to be honest, and they can sit standby ready for years, unlike pressurized hydrogen. Interestingly, if the hydrogen is grey (made from methane) - and it most likely is - then the CO2 per kWh is lower from direct propane combustion.
Fuel power for EV charging. How logical. 🙄Oh wait, fuel can be used to just drive ICE and you don't need to have the additional costs. How to get EV charged out in the middle of nowhere w/out using fossil fuel? 🤔 Solar panels. Extra cost too. 🤔 Slow, but that is the name of the EV game. Slow everything down. 😉
A vast majority (95%) of hydrogen is currently made by steam reforming of natural gas. This is the cheapest process but it creates CO2, CO, etc. as waste byproducts. The production of hydrogen by electrolysis is much cleaner, but more expensive. Also, water does not want to be split, so this is a very inefficient process. Perhaps the price will come down so this will be the more affordable option. However, we are not there yet.
Solar and wind need to be advanced to make hydrogen cheap, so we have many options to make this viable. GM is looking at this seriously as an option for job sites shows there's change happening.
This is about as brilliant as the Chevy Volt’s ICE being used as a generator for its EV motor and NOT to help power the car. GM is amazing at wasting money on dead-end technology. The GOV better not bail them out again….
Why not just focus on the more practical solution of hydrogen fuel cell vehicles. Refill in the same time as gas and even more eco friendly than an EV due to reduced lithium requirements.
Wouldn't it just be better to run the vehicle off of hydrogen? With this setup you have the cost of a vehicle with big batteries, plus the cost of the hydrogen charging unit.
A solution looking for a problem. A reasonable sized battery with electric drive and a hydrocarbon range extender is the best combination for large vehicles.
What will they think of next? Maybe a solar charged battery that can then charge E Vs . Naw, that would never work, how would they sell all that hydrogen nobody wants.
It's a shame hydrogen cars never caught on. Yes they're inefficient, but I think it still combines the best aspects of ICE and EVs. Quick refilling and low running cost. Maybe a hybrid of ICE and hydrogen would be perfect
They leak. They don't' really talk about that part. You are not supposed to keep them in enclosed garage spaces as a leak pools around ceiling and is flammable from as little as 4% mix in air.
$1 per KW to fill up a 200KW battery is $200. That's not very affordable/practical at all. To fill up a 25 gal fuel tank with regular gas at $3.20 a gal is $80.00 in Texas. Gas stations are pretty much everywhere vs Hydrogen and or working EV chargers.
This isn't for your average EV driver, this is for special cases where you need DCFC but don't have a grid hookup, such as this in the middle of a field.
Because a hydrogen tank in the car is less optimal. It's an efficiencies of scale problem, and a bit of a safety issue. much like a hybrid vehicle you have both the battery and an engine. Which means you're paying for both.
This seems limited to events, there's not many places they don't have power that you could get this. I'd imagine the cost of showing somewhere and actually paying for this most people would opt for level 2 charging
Conversion losses and lack of infrastructure. Everytime you convert from one form to another you lose some of the energy. Better to just straight from wind or sun to the vehicle battery.
Too many unanswered questions but then can you create it at home using solar panels, no, who are you paying for the privilege, oil companies(again), where does most of the H2 come from currently fossil fuels, can you plug in anywhere even a 120V outlet to fill up, no. For passenger transport I just don't see this as a solution, long haul shipping yes, long haul flights yes, trains yes(those that aren't electric such as in the EU or places that understand trains and train systems).
Except it takes much more energy to produce the hydrogen. Put the electricity directly in the batteries. The infrastructure for hydrogen doesn't cost anything? 😅
Let’s make it more convoluted, that’s the American way. I think a diesel truck delivered all that equipment. Inflation deduction act…. Let’s spend money we don’t have. More government spending
This dad is so bad and such a mainstream guy. I hope, "Thomas" the sun gets out of TFL very quick, working with your dad must be so limiting for you, you deserve better!
They have solved a problem that didn't need to exist. This is like using a diesel generator to charge an EV. You're better off just driving a diesel car. The point is that it would be much more efficient to just use a hydrogen fuel cell vehicle and ditch the batteries. Anything to look like you're saving the planet right?
Hydrogen is dumb. It leaks. It's the universes smallest molecule and needs to be stored at 400 bar, 400 times atmospheric pressure for cars or this purpose. It doesn't stay put and is impossible to stop leaking. When it leaks, it rises so keeping your car in an enclosed garage is not allowed (if using it in a vehicle). It only needs to be a 4% mix with air to be flammable. People who work professionally with hydrogen, are very, very aware of the risk of using hydrogen and this generally scares them. A solar station powered mega battery pack is far more efficient can be truck mounted if needs be and uses the same batteries as vehicles so economics of scale are on your side. This setup is so limited in its application it's laughable.
"3 phase DC Charging" My head just exploded.
Wut Da?

With this it does the extra step of converting from H2 to electricity, then storing that electricity in the EV's battery, plus the energy to haul the equipment. Sure, fuel cell vehicles have small batteries, but I think that is more to do regenerative braking, etc.
What they always fail to tell you is that hydrogen cost more than three time as much for the same distance in electricity. 95% of the worlds hydrogen production is grey hydrogen which is from methane reformation, coincidentally producing large amounts of greenhouse gasses. Not only super cost effective but also great for the environment.
Grey. Blue supposedly captures most of the carbon, but is not successful at scale. Most hydrogen is grey (methane) or black (coal) and emits all it's CO2 into the atmosphere.
- no that was included, this was touted as experimental proof of concept, not an economic solution - Diesel gensets are the current grid isolated solution to generate electricity in the absence of a solar or wind array..
@@kadmow Porsche’s battery truck for charging 10 Taycan’s at once at 350kW is an interesting solution too - obviously can’t be refilled in the same way this can, but a fleet of them being trucked to renewable charging and back to sites would also work. I doubt they are cheap either.
Very cool uses for hydrogen tech! 👍
"Pure water, but don't drink it"!....lol
So charge your EV with fuel. How novel. Maybe natural gas, diesel or gasoline too? Maybe just start with a vehicle that uses fuel and skip the whole EV part? There are some significant losses with the switching back and forth. The amount of losses, back-end costs and infrastructure that goes into keeping these EVs running is mind boggling.
EVs are easy, we have electric most places. It's the power distribution that is problematic. More energy is coming from rural areas with solar and wind. Need more battery storage and high voltage transmission lines.
Actually .... EVs are very cheap to fuel directly from gird connected renewables. Charging stations are cheap as chips to add, and AC chargers are very cheap, an overnight fill is fine for a lot of use cases including the majority daily driving we all do.
Don't conflate the complexity and cost of hydrogen with EVs - they have very little to do with each other. You can fill an EV from a Diesel generator if you have to, and that emits less CO2 per mile than a diesel combustion engine does due to the efficiency of the generator and the EV combined. (Bloke in the Australian outback did it as a test).
This looks an awful lot like GM trying to avoid writing off their hydrogen costs as a complete loss. Something Toyota will eventually have to do too.
@@jghall00 - all the cars plugged into the grid most of the time will be the batteries everybody is looking for - every carpark will have a charge point at every bay at some eutopian point, those don't need to be very fast to recharge for the few miles of typical commute - then the houses can suck down whatever energy they need overnight (if the wind doesn't blow, while the sun doesn't shine) - leaving the next day to rinse and repeat.
(Some time between now and 2050 we will actually sort out all the energy balances to see if there is any net reduction in pollution - or if bulk nuclear economies will offset the emissions im the places without nuclear.)
So, how are you running the compressor? Gas?
Electric motors, they've been powering compressors for over 100 years.
This is very usable on construction site
Right next to the welding station.
Pretty sure brains don't blow up from pure oxygen, but fires would go crazy
Pure Oxygen actually does not burn. If it did everytime you lit a match the world would burn up. 😂
That is why we need gasoline etc fire needs fuel and oxygen.
it's almost as if Rambling Roman doesn't know what he's talking about.
Could this be put in the bed of a truck as a range extender or a battery be placed in it as a range extender?
- yes with no load space to spare, lol.
The temporary site thing is probably the only use for this. Hope United Rentals, Sunbelt, etc. all get a few of these to move around the country for disaster relief.
Can’t wait to see one of those powering Heavy Equipment, excavator, etc.
JCB has a loadall, backhoe and excavator running hydrogen. Also have a genset running hydrogen. Anything running their JCB 4.4L engine can essentially be a near future hydrogen build.
This solved a problem, remote-location EV recharging. Might get a lot more calls for that than what I'm thinking.
How many people have solar farms?
This seems backwards or behind the times to me. They already have cars and stations that fill cars up with Hydrogen, then the cars convert the Hydrogen into electric. I guess this idea will be obsolete in a very short amount of time. Either charging stations will pop up to replace this or further out we will have hydrogen / electric cars everywhere.
Carvana is selling every compliance car. There are also a few others. What is the safest car and the safest year to buy from Carvana?
I'd be interested in seeing a race w/ this charging system vs. one with a diesel genset.
At 60kw it would take the same exact time. What do you mean by race?
"3-phase DC-charging" rofl...
I wonder if there is a realistic way to produce hydrogen at remote sites using solar or wind and electrolysis. If that were the case, this would have real potential essentially solving the intermittent problem we have with wind and solar. Since about 95% of the hydrogen produced these days is with steam methane reforming, I'm not sure I see the point. Why not just have a generator that runs off propane or natural gas if the total emissions are similar to those resulting from producing the hydrogen? Are there actual plans to expand production of "green" hydrogen?
You make a good point on the propane generator, if the hydrogen is grey (as most is), hydrogen is worse on CO2e per kWh, and propane is a lot easier to handle, and you can bring far more energy onsite in the same space.
(Source EIA - US Electrical Generation) Propane 0.97lb per kWh - 439g per kWh.
Grey hydrogen, 9 to 12 kg CO2 per kg of H2, at 14.5kWh per kg, 620g to 830g per kWh through a fuel cell.
The problem with renewables going via hydrogen is you lose 66% of the input electricity, better to use a battery for multi-day storage, or overbuy on vehicles so you can have some charging while using others - most fleets have surplus vehicles to account for servicing downtime, a mix of wind and solar gives a somewhat consistent supply, and you may get overnight charging which is more useful, wind can break down though, being mechanical.
Even at the current cost quoted in the video, the cost per mile is lower than gas
How do you figure? This truck has a 450 mile range- so $200 for 450 miles, thats over 44 cents/mile. My gas F150 will go over 600 miles on a 36 gallon tank- at $3.50/ gallon thats $126 for 600 miles, or 21 cents per mile.
I would think it would have great applications for disaster areas, to counter all those naysayers who say you could not charge your car if the grid is down due to a disaster.
Propane gen-sets already fill this need to be honest, and they can sit standby ready for years, unlike pressurized hydrogen. Interestingly, if the hydrogen is grey (made from methane) - and it most likely is - then the CO2 per kWh is lower from direct propane combustion.
We pay 5 cents per kWh, off peak , 10 pm to 6am
Charging at 60 kW for one hour equals 60 kWH per hour (not per minute).
6:44. He said 1KW per minute
Fuel power for EV charging. How logical. 🙄Oh wait, fuel can be used to just drive ICE and you don't need to have the additional costs. How to get EV charged out in the middle of nowhere w/out using fossil fuel? 🤔 Solar panels. Extra cost too. 🤔 Slow, but that is the name of the EV game. Slow everything down. 😉
This is a great idea for remote locations without a lot of electric infrastructure. Just drop a trailer full of hydrogen when it runs low.
A vast majority (95%) of hydrogen is currently made by steam reforming of natural gas. This is the cheapest process but it creates CO2, CO, etc. as waste byproducts.
The production of hydrogen by electrolysis is much cleaner, but more expensive. Also, water does not want to be split, so this is a very inefficient process. Perhaps the price will come down so this will be the more affordable option. However, we are not there yet.
People seem to forget you can use sound to make electricity as well, and cities are noisy.
??
Solar and wind need to be advanced to make hydrogen cheap, so we have many options to make this viable. GM is looking at this seriously as an option for job sites shows there's change happening.
Ever heard of a Tesla Megapack? 3,9 MWh and can be charged from solar...
This is about as brilliant as the Chevy Volt’s ICE being used as a generator for its EV motor and NOT to help power the car. GM is amazing at wasting money on dead-end technology. The GOV better not bail them out again….
Imagine how bad inflation would be if the government wasn't spending billions of taxpayer dollars on this!
Why not just focus on the more practical solution of hydrogen fuel cell vehicles. Refill in the same time as gas and even more eco friendly than an EV due to reduced lithium requirements.
Roman: “What is this? What is that? How does that work with this?”
Wouldn't it just be better to run the vehicle off of hydrogen? With this setup you have the cost of a vehicle with big batteries, plus the cost of the hydrogen charging unit.
1st....Have a good day everyone ✌️
A solution looking for a problem. A reasonable sized battery with electric drive and a hydrocarbon range extender is the best combination for large vehicles.
So now I would need to purchase two trailers along with the ev truck…. How can anyone make financial sense out of this.
This is a blody marriage of AC and DC.
Where a 3phase AC compressor doing mechanical work to generating DC from Chemicals.
another painful video to watch with Rambling Roman. Roman, just stay in the office.
What will they think of next? Maybe a solar charged battery that can then charge E Vs . Naw, that would never work, how would they sell all that hydrogen nobody wants.
It's a shame hydrogen cars never caught on. Yes they're inefficient, but I think it still combines the best aspects of ICE and EVs. Quick refilling and low running cost. Maybe a hybrid of ICE and hydrogen would be perfect
They leak. They don't' really talk about that part. You are not supposed to keep them in enclosed garage spaces as a leak pools around ceiling and is flammable from as little as 4% mix in air.
$1 per KW to fill up a 200KW battery is $200. That's not very affordable/practical at all. To fill up a 25 gal fuel tank with regular gas at $3.20 a gal is $80.00 in Texas. Gas stations are pretty much everywhere vs Hydrogen and or working EV chargers.
This isn't for your average EV driver, this is for special cases where you need DCFC but don't have a grid hookup, such as this in the middle of a field.
Why not just hydrogen powered EV’s?
High cost, low efficiency. Lack of places to fuel…
Because a hydrogen tank in the car is less optimal. It's an efficiencies of scale problem, and a bit of a safety issue. much like a hybrid vehicle you have both the battery and an engine. Which means you're paying for both.
This seems limited to events, there's not many places they don't have power that you could get this. I'd imagine the cost of showing somewhere and actually paying for this most people would opt for level 2 charging
Now they just need an onboard diesel generator to produce the H2, lol
Conversion losses and lack of infrastructure. Everytime you convert from one form to another you lose some of the energy. Better to just straight from wind or sun to the vehicle battery.
Too many unanswered questions but then can you create it at home using solar panels, no, who are you paying for the privilege, oil companies(again), where does most of the H2 come from currently fossil fuels, can you plug in anywhere even a 120V outlet to fill up, no. For passenger transport I just don't see this as a solution, long haul shipping yes, long haul flights yes, trains yes(those that aren't electric such as in the EU or places that understand trains and train systems).
Except it takes much more energy to produce the hydrogen. Put the electricity directly in the batteries.
The infrastructure for hydrogen doesn't cost anything? 😅
Its too energy intensive to make hydrogen, and nobody has figured out how to fix that. so it just isn't an answer.
Let’s make it more convoluted, that’s the American way. I think a diesel truck delivered all that equipment. Inflation deduction act…. Let’s spend money we don’t have. More government spending
Now let's remove the massive dumb batteries and just use hydrogen fuel cells, done.
What a massively inefficient means of creating power. Fuel cells are cool, this however is extremely silly.
With reference to Shakespeare.
"Complication"
Thy name is hydrogen cell fast charger.
Its another of first world problems.
😊
Lets just keep our gas powered at home with a bulk fuel tank as a proper farmer has
No need to convert to ev
you can breathe 100% oxygen.... but yes... long term there will be issues
This dad is so bad and such a mainstream guy. I hope, "Thomas" the sun gets out of TFL very quick, working with your dad must be so limiting for you, you deserve better!
Customers? Santa Class
Anyone want to bet its a million?
The gm engineer is upspeaking badly (every sentence is a question?)
GM many Years with this and it old tech too not new... Yet???? ;-D
Nope it will be stuck on the side of the road getting recharged by a gas or diesel generator as they usually do🤣
They have solved a problem that didn't need to exist. This is like using a diesel generator to charge an EV. You're better off just driving a diesel car. The point is that it would be much more efficient to just use a hydrogen fuel cell vehicle and ditch the batteries. Anything to look like you're saving the planet right?
Baloney. 3 gallons of fuel in our generator takes our EV6 from 10% charge to 100% charge. About 270 miles. Do the math.
@@Dive-Bar-Casanova You're still burning fossil fuels.
Where does this H2 come from? Diesel generator. Lol
@@Dive-Bar-Casanovathat's one hell of a generator. 3 gallons of gas charges it to 100% (from 98 % I assume)
Interesting 🤔 early stages just like everything new. Let’s wait and see what develops.
😂
Hydrogen is dumb. It leaks. It's the universes smallest molecule and needs to be stored at 400 bar, 400 times atmospheric pressure for cars or this purpose. It doesn't stay put and is impossible to stop leaking. When it leaks, it rises so keeping your car in an enclosed garage is not allowed (if using it in a vehicle). It only needs to be a 4% mix with air to be flammable. People who work professionally with hydrogen, are very, very aware of the risk of using hydrogen and this generally scares them. A solar station powered mega battery pack is far more efficient can be truck mounted if needs be and uses the same batteries as vehicles so economics of scale are on your side. This setup is so limited in its application it's laughable.
