Batteries are much more efficient.
That's why everyone is using them.
Hydrogen conversation from electrolysis, maybe 50% efficient some day with tech that does not exist beyond lab experiments. That's at least a 50% loss just to convert the H2O into H2 and O.
Charging and using a lithium Battery to get power to the wheel, worst case scenario is around 70%. That's power grid to wheel.
