At a somewhat small and unassuming airport in Maribor, Slovenia, German hydrogen propulsion startup H2FLY has quietly been building up to a major milestone in zero-emission aviation over the summer. And all the hard work has come to fruitio
World’s first crewed liquid hydrogen plane takes off::undefined
Aviation is the one field, where burning some form of carbohydrate is actually the only viable option. Batteries may be an option for short flights, but I don’t see any solution for long haul flights.
Whether the fuel ends up being (synthetic) kerosene or some plant oil stuff doesn’t really matter, the turbine isn’t going anywhere.
Yeah getting aircraft onto renewable energy is probably the lowest priority, if everything else was renewable it wouldn’t even matter if they were never renewable.
LEL for Hydrogen: 4.0 (% in air)
UEL is 75 %
This is the most severe (wide range) for any fuel.

This is on top to hydrogen enbrittlement and low temperature enbrittlement of metals.
Good luck with the insurance fees for commercial flights.

I agree…
( except for a small typo : it’s carbohydride or hydrocarbon )
no no, the planes need a big plate of spaghetti before long haul journeys
