There are laws of thermodynamics and there are laws of kinetics.

Fuels have much more power density than batteries. You can't deliver power as fast with a battery compared to a fuel. It doesn't matter if thermodynamically one is more efficient or greener than the other. You would be crazy to suggest moving an airbus with a battery, that's physically impossible.

I'm a researcher in both fields (batteries and hydrogen)

Sure, but I'm not talking about jets, which yeah, do need a far greater energy density than batteries can currently provide.
