My understanding is liquid hydrogen could be a contender for a green jet fuel alternative. Batteries are too heavy.
- jacquesm 3y agoI think we'll see a synthetic version of jet fuel before we see a hydrogen powered plane in mass production. Far less trouble to store and use and much higher energy density, also works with existing airframes (fuel tanks!) and engines.

- MBCook 3y agoThe big problem is that fueling with liquid hydrogen is not easy. Getting things down to that temperature is not easy. Getting hydrogen cleanly is not easy. I mean if hydrogen was just as abundant in the atmosphere as oxygen and didn’t need to be at ridiculous temperatures to be liquid, it would be a great fuel. But to keep things green you’re fighting a ton of trade-offs using electricity, it which point why don’t you just use the electricity directly?
- konschubert 3y agoMy understanding of the airline industry is that it will be MUCH easier to further synthesise that green hydrogen into proper jet fuel than to build and certify a jet that runs on Hydrogen.
