Reply to comment by Fearlessleader85 in Rolls-Royce successfully tests hydrogen-powered jet engine by je97

Considering how long it takes the FAA to certify unleaded fuel, which is supposed to be done by 2030, I can't imagine how long it would take to certify a hydrogen powered plane.

I certainly wouldn't plan on buying tickets on such a plane any time soon.

Yea it's looking more like the airline industry will transfer to biofuels and work to be carbon neutral than go for non carbon fuels.
