Hydrogen is an energy storage medium, not an energy source.

You need to use energy to create hydrogen - and the energy required is 5x what would be required to just store the same amount of energy as electricity in a battery.

55kWh of electricity for hydrogen generation results in around 10kWh at the wheels of a hydrogen car.

Or you can just shove the 55kWh directly to an EV battery.
