We can crack the water genie to get hydrogen, easy. But it's a non-starter because you take relatively expensive renewable electricity to produce 1/4 the energy in the car. At least batteries are about 50% efficient.
Maybe, just maybe we'll have government subsidies for farmers and essential trucking industries to do the uber-expensive hydrogen
thang, if there's no other way. But I understand it's
really going to cost society doing it that way.
Hydrogen will always be a premium fuel for the essential sectors, not you and I. We'll get around on dinky little EV's with a 120 km limit (before 5 hour recharge).
I was just hoping that we might have some of the alternative fuel for farmers here, in biochar fuel. (Biochar fuel will not power broader society or fill my 6 cylinder Mitsubishi wagon!)
