Well, I don't think hydrogen is the answer for all EVs. and I agree the lack of infrastructure is a big problem. The main infrastructure (Grid) already exists for BEVs, and I think, too, is the best solution for cars and other light vehicles on the road. However, the energy density of hydrogen fuel cells is much better than current BEV technology, so could lend itself better for large transport vehicles (trains, semis, etc), incl aircraft (which are very weight sensitive). But it is all new at this point, so will have to see where it goes. I like that we don't put all our eggs in one basket, though.
