Hydrogen ICE is a pipe dream. BMW tried it in the early 2000's and failed. Toyota is prototyping it without much fanfare. (Their current test car, a tiny Yaris can do two laps of the test rink before refueling and maintenance).

All cars in the future will be propelled by electric motors. The only thing we're arguing is how are they going to transport the energy. Batteries? Hydrogen fuel cell? Some kind of generator, running biogas or 100% synthetic fuel? Most likely all of the above, depending on the use-case.
