Airbus pushes back ZEROe timeline and ditches A380 fuel cell flight-test plan
8 Feb 2025

Airbus has delayed the service-entry target for a hydrogen-powered aircraft developed under its ZEROe project by up to 10 years and axed plans to flight-test hydrogen propulsion systems,

Green hydrogen is further away than nuclear fusion. I think long range aviation is the trickiest of the net zero challenges. If sustainable aviation fuel is a real thing as opposed to greenwashing then I suppose it might be easy enough, but I suspect there are sordid little details that make it less green than the enthusiasts claim. https://afdc.energy.gov/fuels/sustainable-aviation-fuel

"If your motor would drive a turboprop" ... I'm guessing you mean "prop" rather than "turbo-prop" ... a turbo-prop has no meaning with an electric drive.

Possibly the least "crazy" solutions are ...
1) SAF
2) Carbon capture in flight ??
3) the end of cheap commercial flights
4) rebirth of sailing ships ??
5) using ammonia as fuel ??
6) the realisation that aviation is only a tiny contributor to total CO2, coupled with "massive" taxes on commercial flights (which the government will pocket, "thank you very much").

The whole system costs of H2 are staggering

Thanks, I meant propeller, of course.
