I agree, it only make sense if you have so much excess solar that you don’t know what to do with it in peak production. Even then, you need to factor in the depreciation of the hydrogen facilities.

Not really, electricity prices only need to fluctuate by a factor of four for this to be economically viable.

But is it completely green? I live fairly close to a huge lithium deposit, and while people from western world are enjoying the benefits of EVs, people around here might get their habitat destroyed.

In my book it’s not green if it’s not completely green. And EVs are certainly not.
