Reply to comment by brcguy in Rolls-Royce successfully tests hydrogen-powered jet engine by je97

I mean, you could be right, but with the lifetimes we're demanding of aircraft, i think it would behoove us to keep everything from hydrogen embrittlement. Injectors might be the main trouble spot, though.

Yeah plus I think storing a suitable volume might be a problem too. Just need to make a super efficient electric turbine and then build the whole airframe out of batteries lol.

Who are we kidding - the climate crisis will only be solved by the climate crisis killing half of us. Now I’m sad.

Nuclear!

Actually skip the electric engine, just use the fuel to heat the air.

90% sure the US dreamed up a plane like that in the 60s.
