A hydrogen car should also start too. I am just pointing out that this is a hit or miss thing at -30°C.

Fuel cells do not consume fuel. It converts hydrogen and oxygen into water. You can reconvert water back into hydrogen and oxygen. You can conceive of a fully closed-cycle system for this. But it's not worth it, since you are just carr

Hydrogen is also one of the most common elements in the Earth's crust. Hence why it will never run out. It is very relevant.

So basically when you make a mistake, and the other person makes a mistake, it means that the other person is liar but you're just making a mistake. Got it. This conversation is going to end here. You are simply not worth debating agai

So two years, not several. I am not a walking encyclopedia. But you are a troll for acting like this. The point was that VRE is still a tiny part of the overall grid. It will stay like that for a long time to come. And the original point th

Michael Liebriech could easily have a vested interest to BS. In fact he probably does since he has made similar statements in the past. Ammonia is an option too. But this does not preclude other ideas.

At -30°C many cars won't start. This is an extreme situation. But it does seem like the Mirai should be able to start: https://insideevs.com/reviews/460274/2021-toyota-mirai-test-...

Even in that case, it is only 2021 that it happened. So VRE has not exceed nuclear for "several years." You are guilty of your own accusation of constantly lying. Also, Eastern nuclear power growth has displace Western nuclear shu

Not true at all. Nuclear is still bigger than VRE: https://ourworldindata.org/electricity-mix And that is with a dramatic reduction in nuclear power in recent years.

Hydrogen works nearly exactly like CNG. People have created fantasy stories as if it was the blood from Xenomorphs. In reality, it's corrosiveness is pretty underwhelming. Actual issues related to corrosion or hydrogen embrittlement on

That's utter nonsense. These things are rated at a specific power output. People have actually driven them to very high mileage and not seen such dramatic declines. Not to mention that these things degrade similar to batteries, with a

And replaced it with natural gas... Coal is nowhere near dead. Europe is increasing production right now. People have greatly exaggerated the death of fossil fuels. We are decades away from moving away from fossil fuels. A lot of the opposi

Iron is one of the most common elements in the Earth's crust. It is not going to run out.

Neither natural gas nor hydrogen leaks in appreciable amounts in pipelines. They do care about profits, and leaky pipes lose money. You do not need 4x as many ships. You just need bigger tanks. Hydrogen is much lighter than LNG. Bigger tank

Should be noted that fuel cells are batteries. We can already eliminate this problem right away. But we must "wait" for future batteries for no reason at all.

Hydrogen is the same. Green hydrogen -> hydrogen vehicles. Just without the huge resource needs of battery manufacturing.

The point is that any material below lithium on the periodic table will likely result in a lower energy density battery chemistry. If you want something fundamentally superior than li-ion, there's really only one option. Hence why any

Nearly all electricity comes from fossil fuels too (well, ignoring hydroelectric and nuclear). Renewables still make a small contribution to the grid, and 10 years it was tiny. It's obviously just history repeating itself. People compl

For a charging outlet, electricity is arguably simpler. But that is not what I was talking about. I was referring to large scale distribution of energy. We're talking GWs and hundreds of miles here. In that case, it is easier to move a

People have actually looked seriously at what a world of only EVs would look like. It is basically a disaster of unsustainable resource consumption. Hence the need for hydrogen cars. EV believers have their own misperceptions about what is

5000 hours * 50 mph is 250,000 miles. That's plenty.

Transporting hydrogen is easier than transporting electricity on the large scale. A pipeline is both simpler and more scalable than wires after you get to a certain size.

Industrial scale electrolyzers exist now and are being deployed. The rest of the your post is just attacking strawmen. None of those problems exist at the scale that you think they exist. For instance, fuel cells are already lasting tens of

Yes, and it's likely that VW will shift away from their all-EV strategy. They are already investing in fuel cell trucks and e-fuels. In reality, EVs are just one step in a long chain of future changes in the transportation industry. Pe

You are misreading my statement. There is literally only one element directly above lithium on the periodic table. I was not referring to atomic mass. Hydrogen is not burned in a fuel cell. It works the same way as lithium does in an li-ion

Hydrogen cars from 40 years ago had the same problem. They were terrible cars with short ranges too. This has changed with newer technology. The biggest advantage of hydrogen is that they also solve the most severe environmental consequence

This is totally incorrect. A fuel cell is a type of electrochemical cell. A fuel cell car has an electric motor just like a conventional EV. We often use the terms “BEV” and “FCEV” to differentiate them.

EVs are over 100 years old. They were an abandoned idea until environmentalism drove their readoption. Environmentalism will make other ignored ideas come back.
