And, theoretically, you can fill up your car the same way you can with diesel or gas.
I’d like a hydrogen powered bicycle. I think that would be cool.
Ok. Or motorcycle. Well, for that matter toys too, and drones. Damn! Anything with an engine!
>>And, theoretically, you can fill up your car the same way you can with diesel or gas.
No, you cannot. H2 is not a liquid at STP (standard temperature and pressure). Diesel and gasoline are. This matters, bigly. H2 is a light, devilishly small molecule that likes to leak and likes to embrittle steel. To have enough of it to do useful things, it needs to be in a tank at fairly high pressure. This is expensive/difficult
Additionally, there isn’t much of it, at least not in the form needed for a fuel. H2 must be manufactured. What is your input energy source?
H2 is a fake bill of goods only a government regulator could love.
