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.
You can use liquified hydrogen which need to be chilled and insulated, and will evaporate away in a short time if not properly sealed
Or you use compressed hydrogen which means you are basically carrying an IED that weighs several hundred kilograms with the amount of pressure inside the gas tank
And hydrogen combustion is as others have said, inefficient.
Another issue is that you also need to use basically pure oxygen if you want to use a hydrogen fuel cell, otherwise the catalyst inside the cell would get poisoned
And well, there is a car that did all that, the Toyota Mirai, but that also pretty much ended in commercial failure, due to lack of hydrogen filling infrastructure and a whole load of other reasons.
Everybody keeps talking about all the problems storing hydrogen, but that’s just quitter talk. You know how you solve 'em quick and easy? You simply combine the hydrogen with some carbon to make a convenient liquid fuel! As a bonus, you don’t even need to develop fancy new fuel cell tech: you can burn it in the same engines we already have.
You need green energy to produce climate friendly hydrogen. This is a LOT more inefficient than to just use that green energy directly in EVs. Thus green hydrogen is also expensive and most importantly it is needed in the industry. It’s the same with e-fuels.
I don’t think any average person would know of these advantages. So theres a general lack of education about the topic.
There is also a hydrogen refueling network problem to overcome. Before public electric charging stations existed, electric people could charge at home and install their own chargers where required so the electric industry has been able to partially side step that issue at the beginning.
Finally I think it just doesn’t seem sexy. To a casual bystander it’s like gas in, pay, then drive as usual.
Because right now we don’t have that much excess energy… Therefore it’s just a waste of energy to use it, because it is way less efficient. AND on top of it an hydrogen car also needs a battery just a smaller one. So it has all the downsides without any upsides. The only upside is that you can recharge your car faster and it has some more range. But both those things don’t matter for the average consumer
It makes sense for long haul trucking and aviation vs batteries, at least for now, but it doesn’t scale well for most common consumer vehicles. Any hydrogen vehicle needs to be a hybrid because there isn’t the fine tune fuel ratio control you get on traditional gasoline.
probably because of infrastructure. electric charging stations were one of the first around and if you ask a new car buyer to choose between two renewable fuel sources, they’ll chose the one with the most stations. In the US at lease, hydrogen stations have always been few and far between, and often quite pricey.

(Half of me is serious, and the other half is making a Key & Peele style “motherfucker that’s called gasoline” joke.)

Production is wildly inefficient and the storage and transfer of the stuff is quite tricky.
Hydrogen might get more prominent in the heavy vehicles, with few more innovation.
