I'm , personally, including hydrogen in the overall solution, but like battery-based EV's
hydrogen has a very long way to go to broad-based use and commercialization.
The gasoline/ethanol response is obviously not forever, but it is needed for quite some time.
Industrial power went from wood to hydro( some wind)to coal to oil to gas to nuclear to wind/solar
and now what ? It won't be dirty, rare earth containing, short-lived batteries as we know them now. Maybe organic batteries ...maybe. Still a battery based EV system requires a very large grid...VERY.
Cheers.
