If we can use hydrogen to power electric motors, why can’t we use water to run a car? - eviltoast

Can’t you just break down water, use the hydrogen to power the electric motor, and I don’t think O2 as a byproduct is bad, now this is of course an ideal condition, but why hasn’t this been looked into more?

    Iirc the energy required to break down water into hydrogen and oxygen is greater than what burning the mixture produces, but in theory solar power might be a viable option to a certain extent.

    Efficiency/viability would probably be nonexistent without some sort of miracle catalyst for the breakdown process.
