Maybe, but a tank of hydrogen burnt through an ICE is much cheaper than either
For your storage and production concerns, here it is working in practice

- Tade0 2y ago> Maybe, but a tank of hydrogen burnt through an ICE is much cheaper than either It's really not. Most of the hydrogen bus projects were killed by the surprising cost of fueling - approximately 4x the cost of electricity. And no wonder: just the energy wasted producing hydrogen and then using it in a fuel cell is enough to build a battery pack that will last the equivalent.
- jimnotgym 2y agoIs that the cost of the fuel itself, or the high cost of providing it in a world with little infrastructure?
- Tade0 2y agoAt its best, generating hydrogen and then putting it through a fuel cell is less than 50% efficient, and that's discounting all the losses present both in BEVs and hydrogen cars. Hydrogen combustion engines slash that efficiency in half. Even if you handwave over the hardware required to do all that, the cost is double that of equivalent electricity.
