I think the efficiency of pure EVs is too good to ignore. I'm not disagreeing that we have to have hydrogen to hit zero emissions, but lots of factors related to personal vehicles where pure EV makes sense. I don't think they will be the only types, possible over time as green hydrogen economics improve we might see more of a mix for sale.

But given how long it will take to build out to 3x renewable generation capacity and then auto makers to change, etc etc I don't think that will be for another 10+ years, but hope I'm wrong.
