Well H2 fuel cell were used on first man space missions so there’s that.
CATL just announced a 500 kWh per Kg battery. Price I don’t know. But with Tesla Semi truck viable now and could soon double the range H2,better hurry as heavy trucks are likely to go EV. Folks at enfluit energy might add to that trend.
The only for H2 is the theory naturally occurring H2 can be found deep in the earth. Maybe so but EV will have a decade head start.
