I challenge the assertion that hydrogen is feasible. Is hydrogen more energy dense (in either energy per unit volume OR per unit weight) than traditional fuels? It might be better than batteries, but I'd be surprised if it was any better than current fuels. |

Chemically, yes. But in reality, very far from it.
The bulky high pressure cylinders needed to store the gas (unlike propane etc, it doesn't liquify) easily weigh an order of magnitude more than the mass of gas they contain.
