I think there's definitely room for hydrogen, but the interface analogy falls flat for hydrogen. It's not like you can just drop in another fuel type into a hydrogen car after it's produced? The strength of electricity is that the backend is agnostic. It can be hydro, nuclear, sun, or some other future fuel. Hell, you can could run electricity using hydrogen if you wanted.

oh yeah, I meant the hydrogen production source could be changed from not green to green. Exactly if you have extra green energy you can just produce hydrogen with it.

Yeah, that's totally reasonable. I have a friend that has a Mirai and it's really really cool. We just need to build out more infrastructure.
