Rolls-Royce flies engine on 100 per cent Sustainable Aviation Fuel

  1. Good new I guess, although I did have to look up what SAF (sustainable aviation fuel) is. Apparently it’s a type of biofuel, til.

  2. Oh so that’s what SAF is about. I thought it was something like SAS my employer would force me to get certified in..Phew..

  3. Sustainable Aviation Fuel is bullshit. All biofuel production does is hog arable land for the production of fuel instead of food. Not really sustainable.

  4. I understand the engine runs on biofuel. By the way, the USSR already flew experimental planes on liquid hydrogen in 1988, the Tu-155 with the HK-88 engine. If it wasn’t for ’91, Soviet hydrogen-powered planes would probably be flying now

  5. Turbines can be made to run on most liquid fuels. The turbine is not groundbreaking. The fuel might be, but probably not. Biofuels are not new. Sounds like a puff piece.
