Fun project! But replacing gas with hydrogen seems really tricky. Hydrogen is much harder to transport without leaks because it's such a tiny molecule. Electric seems better than trying to still burn hydrogen.
Electric is far more efficient too, thus cheaper. Electricity you can transit over distance over wire and generate however you like. We've done it a long time, far and wide.
Turning electricity into hydrogen, distributing it, and then turning it back into electricity to move a vehicle, is so wasteful/expensive.
Just use a big battery.
For some applications like spacecraft where weight is critical, it does make sense to use hydrogen fuel cells as a battery. But usually it doesn't make sense.
Certainly not the way we lunch right now. The energy used, that focused, in that short a time, is insane.
