At best, he doesn’t understand what a Hybrid Car is.
Hydrogen comes from water. Oil comes from pits deep in the earth. To turn an engine: We make controlled explosions inside a steel chamber to turn a crank using refined oil. The theory of operation does not change for hydrogen powered cars, the process of extracting it does. Hydrogen: A truck pulls up to a beach - drop a hose - tank is full so wrap up the hose and drive off. For oil - first you need gigantic oil pumps, then you drill a massive damned hole in the ground. At this point hydrogen is easier. The absolutely insanely stupid statement of “they explode”, yeah you moron, so did the Gremlin when they got rear ended, you don’t blame the fuel you blame the engineer. Complete idiots speaking their mind think they know, but in reality hydrogen and oxygen could replace oil and natural gas over night and there would be no change so long as the systems were engineered to handle the change in gases. Mostly it would be flow reducers because hydrogen and oxygen burn hotter and faster than oil and natural gas. But any explosions outside of the engine itself, are engineering failures, not of the fuel type which is one of the dumbest uneducated statements I have ever heard about a fuel type - " it blows up so I don’t like it" you rancid hotdog, what do you think gas does? A gallon of gas can send a 1 ton car 30miles, if you ignite it directly it can send every part of your body 30miles in every direction. IT’S WHAT FUEL DOES!!! WHAT MATTERS IS HOW WE ACQUIRE IT! THE TECH IS BUILT AROUND THE FUEL! Weak damn humans.
I get your point but hydrogen isn’t just sea water, you’ve got an awful lot more energy to put in after the “tank is full so wrap up the hose and drive off” stage to separate the hydrogen from oxygen to get the fuel. The difficult bit comes after “get water”.
Gonna clarify a few things…
Hydrogen comes from water.
This is like saying flour comes from cake. You’ve got it backwards.

Hydrogen opens up the possibility of using a fuel cell, skipping the noisy and inefficient combustion in favor of directly creating electricity and driving an electric motor.

Not even close. To get hydrogen from water, you need a shit-ton of electricity and a lot of infrastructure, or you need to free it up with a chemical reaction (Aluminum and hydrochloric acid if I remember correctly). Right now the chemical way is lower cost and more available.
It’s better to use that electricity to move the car around, rather than split water with it and using the resulting hydrogen to move cars.
The late, great Heisenberg of New Mexico says that hydrogen explodes!

Broken clocks and whatnot. Hydrogen cars are trash and completely unfeasible, not because they explode but because of the terrible efficiency and fueling problems
And would need a huge new infrastructure for production and distribution. I’m convinced that most of the push for hydrogen is from oil and gas interests wanting to have essentially the same business they do now.
Clearly one of the advantages of EVs is how cheap and easy the infrastructure is compared to any other alternative (and somehow we’re still finding it difficult)
EV infrastructure would be better if it was actually standardized and regulated to be like gas stations.
Right now, we have legacy charging ports and the new, now standard, Tesla port. So you have to make sure the charger will even fit your car. And, because we live in the future, everything is enshitified. Different charging companies have different apps that you need to download to pay for charging, many chargers are down for maintenance, but even with the app, there’s no guarantee you’ll be warned about the charger being down.
Chargers should be like gas pumps. Put in a card, put the plug in your car, and then wait for it to charge. Every plug should fit every car. The system that sprang up without government intervention is clearly insufficient, and needs to be standardized from the ground up.
- Most manufacturers pledged to support NACs starting next year, and a couple already have. Also, Tesla is adding the older standard to at least some chargers
- We might be losing “pay at the pump”, that was required for federal money to build out charging. Now we’re switching to NACs but Tesla hasn’t supported “pay at the pump” and I don’t know if that’s still a requirement. While it is actually more convenient to use the app and Tesla has been consumer friendly so far, I’m uncomfortable with yet another app holding my credit card hostage just so I can adult.
- we should focus on rest areas on highways, both to build out the trip charger network and as something that can more easily be standardized/influenced
But nobody’s actually taking about subsidising or making them, so there’s no point in ranting about it.
Hydrogen buses were a thing for a while, but it’s probably cheaper to just go with batteries now.
Feels like something that was surpassed before it ever got popular.
I could see hydrogen being useful for some applications where you don’t need the public infrastructure. Buses that refuel at a central depot could be one of those if there’s issues with battery electric being too heavy and stuff like that.
But for ordinary people that can charge their car at home or work without needing to go to a third place it’s hard to beat that convenience.
Hydrogen also has a history of being pushed by fossil fuel companies, probably because initially most hydrogen would be generated using fossil fuels, so it’s not exactly a fast track to reducing emissions.
and the need to build an entire new distribution network, but one that handles cryogenic fuel.
nah, no thanks.
Actually they can retro fit oil and gas infrastructure to work with hydrogen. Guess who is pushing the “huRdUGyun iS thE fuTuRe” narrative. Yeah the people who own the oil and gas infra.

citation requested because this defies literal physics. I’d give you the benefit of the doubt if you suggested propane, but gasoline storage is NOT cryogenic, would not hold large enough volumes of it, and aren’t capable of the pressures involved.
Sure, you can bury a hydrogen tank and support plumbing NEXT to a gasoline storage tank, but you still have to deal with handling cryogenic fuel. Do they really claim that?
So even if that’s an agenda, it’s fucking bent. Green Hydrogen literally ISN’T.
Seems like every solution the petroleum industry pushes is really just another excuse to pump more oil to burn in an already choking atmosphere.
fuuuuuck.
Hydrogen fuel cells actually show quite a bit of promise. Mostly for large trucks. Batteries have a scaling issue. A battery powered 18-wheeler needs a much larger battery for a much shorter range.
Adding more load means you need more battery, and that larger battery is just more load that you need to haul.
This is sort of true with everything, but the important note is that a full battery and empty battery weigh the same.
Anyway. Commercial use is where it makes sense. There are actually a few other technologies that make sense in the commercial transportation space. Like ammonia.
Keeping these rather dangerous fuels commercial also allows for more strict safety standards.
From watching movies from the 60s-2020s, internal COMBUSTION engine’s also have a tendency to explode. I haven’t seen many hydrogen using vehicles exploding since the Hindenburg.
Pretty sure the Hindenburg would have gone down the same even if it was filed with helium. Not that the hydrogen helped matters, just the initial problem wasn’t hydrogen’s fault.
No… No, that’s not true. Yes, hydrogen and helium are both lighter than air. But that’s pretty much where the similarities end. Hydrogen is unstable, which is why it can explosively combust when mixed with as little as 4% oxygen. Helium is stable, helium won’t burn. So if it had been filled with helium, it might have crashed. But it definitely wouldn’t have been a catastrophic fireball…
Downvotes for being correct, or at least, not entirely wrong. The exact cause may never be determined, but there are a lot of plausible theories that the fire did not start with hydrogen, but rather the outer coating.
If nothing else, hydrogen can’t burn without oxygen, and there’s very little oxygen inside the envelope. Something else has to leak first.
Thank you. After the deluge I did hit up Wikipedia. The skin was coated in flammable material as I remembered. It did say the skin being a major factor was controversial and that the burn patterns didn’t indicate that to be likely, which is fine. But just the blanket downvotes with no one addressing that is annoying. It stifles any conversation. Were I not a naturally curious person I wouldn’t have looked into it further. I’m sure plenty of the downvotes came from people that probably didn’t even know about the static discharge part and still don’t know because they just downvoted and moved on in their ignorance.
Theoretically a hydrogen fuel vehicle could explode because it has a pretty large tank of hydrogen on board. Practically it’ll just burn up because it won’t all be released at once. And I’ve never heard of a single case of that actually happening in the field. And you can be damn sure it would be all over the news.
I have a hydrogen car. H2 explodes more readily than it burns. The containment tanks are designed to mitigate this, and they are routinely tested with high-caliber rifles to make sure. There are YouTube videos of the tests.
EV battery packs are also designed to mitigate thermal runaway events, even down to Tesla packs making every cell connection a fuse on case of issues. That doesn’t stop them from catching fire anyway after some accidents.
