Comment on New fuel cell could enable electric aviation
Patch@feddit.uk 1 month agoThe real competitor for green aviation isn’t hydrogen, it’s bio-fuel. Bio-kerosene, bio-gas and bio-ethanol all have useful roles in aviation, and are essentially carbon neutral over their lifecycle. Zero carbon at the proverbial tailpipe is a lot less important when that tailpipe is at 30,000 feet.

bio fuels are not scalable. Much more solar energy (15x+ factor) is created by PV than by ethanol per area, and more efficiently turned into H2 (or e kerosene, btw) than the bio route. Bio route is airline PR to do something, but would make food scarce at scale.
