Re: Batteries != energy
Hydrogen can be produced en masse in a constant stream either on site or centralised somewhere (or a mix), electricity can't since changes in demand require ramping up and down of the fuel source. Remember, that's only 1GWh per plane (given my very fuzzy calculations). If an airport needs to refuel say 5 trans-Atlantic flights per hour that's 5GWh. The largest nuclear plant in the world is ~7GWh max and it's about the size of an airport.
