I'm not an expert at all, but I was under the impression that hydrogen requires electricity for it to be synthesized. And that it's quite a bit more efficient just to use electricity in a battery directly instead of going through the process to create hydrogen, store it, and use it. I do think it could be used in situations where the energy density benefits are important (planes, racing).

What do you believe is inside a standard battery? Pure electricity? That doesn't exist. It's a compound that goes through a chemical reaction when you charge it, and which goes through another one when you discharge.

    I don't see how that's relevant to what I said.

      It's relevant to what I initially said. So I'm not sure how your comment relates. Maybe you just wanted to nitpick a word I used to sound smart?
