I don’t understand how hydrogen didn’t win the race. Transports and explodes just like gasoline. Make car go fast. Doesn’t degrade like lithium. Can be “mined” by throwing electricity at water during times of excess generation by renewables. When you burn it, it turns into water. Has none of the national security concerns of distribution of lithium mining and production in other countries.

Hydrogen for cars is a nonsense. It is so inefficient. Unless you are making it from oil, which why the oil companies are pushing it, you lose loads of energy making it. Then it has to storages and transported, which is hard. Then the car use of it is inefficient too.

So ignoring the oil industries’ “blue hydrogen”, and looking only at “green hydrogen”, you are looking at about 22% of the energy generated ending up pushing the car forward! With an EV it is about 73%. So hydrogen car are over 3 times more expensive to run.

Plus you can just plug in an EV anywhere. With an EV, if need be, you can charge, slowly, off a normal home socket. Of course, normally, you fit faster charging at home.

Hydrogen cars is lie pushed by big oil.

To be fair, i think it may have some use for fleet vehicles like taxis and long range buses because these are applications where being able to refill in minutes at a fuel depo you already run actually matters as compared to the stress you would put on a large battery fast charging day in day out. I also believe that Japan has a nuclear plant that is being built with the capacity to efficacy generate hydrogen directly. That being said, for personal vehicles I can’t really see the market of people who need that fast of a refil being large enough to reach the economies of scale necessary to be practical.
