What about hydrogen fuel cells? They got 79% efficiency and can replace batteries of EVs right?

[โ€“] Litron3000@feddit.de 0 points 1 year ago

Yes, but turning electricity into hydrogen doesn't have 100% efficiency, during transport, storage and filling the car with hydrogen you lose some of it and only then you get to the fuel cell, which isn't very efficient in itself. And then you lose a bit more (although very little) in the electric motor. All this amounts to the 22% of the guy above (didn't check the number btw, but it sounds plausible)
