The problems with hydrogen have never been with using it as a fuel source. The first problem is storage/transport of the fuel and the second is what happens to a vehicle with a hydrogen fuel tank when it's ruptured in an accident?

I can see a train making sense - a lot more space for storage and cooling, plus the risk of an accident is very low. But I haven't seen anything about these issues being addressed in motor vehicles.

Hydrogen takes a lot of energy to extract, transport, and store. It makes it orders of magnitude less efficient than simply using that energy to charge a battery directly.
