There’s two problems, or three really — hydrogen storage doesn’t yield good density, liquid fuels are always more compact; there is no hydrogen distribution network and it will cost a fortune to build one; and hydrogen has to be made and stored, and SOLD, all of which will require MORE production of electricity while Clinton and Obama have both fought against coal mining, a fight they have been doing on behalf of their OPEC masters.
I know some companies were looking at using gasoline as the fuel source. A reformer heated the gas and extracted the hydrogen for the fuel cell.
Fuel cells are generally twice as efficient as combustion engines so not only was it cleaner but you get more mph.
Also it solves the infrastructure problem.
Hopefully this works.
