From a reply in FB group TSLA…
Hydrogen fuel cell vehicles will be very common once the electric grids are powered predominantly by renewables. The price of hydrogen will conform to Wright’s Law and be so cheap that it will be competitive with BEVs. And due to the electric grid powering what is now still powered by fossil fuels, the amount of power generated by renewables will be so low cost that hydrogen will be stored in the summer for use in the winter.
I will even go so far as to predict that if Tesla wants to stay in the EV manufacturing business, they will be making HFCEVs. They might still make BEVs for their high end cars. But not just Tesla, all carmakers will have to face this changeover.
