... then the laws of physics & economics raise their ugly heads:

In the image above, we see 100 kWh of energy being used to drive a hydrogen fuel cell vehicle (on the left) or a battery electric car (on the right). Depending on how the hydrogen is managed, 19 or 23% of the energy at the beginning is actually available to drive the vehicle. For a battery electric car, 69% of the original energy is available to drive the vehicle.
I think we have a winner.
