I don't understand how hydrogen didn't win the race. Transports and explodes just like gasoline. Make car go fast. Doesn't degrade like lithium. Can be "mined" by throwing electricity at water during times of excess generation by renewables. When you burn it, it turns into water. Has none of the national security concerns of distribution of lithium mining and production in other countries.

Production is wildly inefficient and the storage and transfer of the stuff is quite tricky.
