Reply to comment by JoJoPizzaG in Rolls-Royce successfully tests hydrogen-powered jet engine | Britain's Rolls-Royce said it has successfully run an aircraft engine on hydrogen, a world aviation first that marks a major step towards proving the gas could be key to decarbonising air travel. by yourSAS

  1. Aircraft don't run on gasoline

  2. You don't need to design a plane from scratch for a new engine. BROADLY speaking it's mainly the horizontal tail that needs to be redesigned to account for the pitching moment from the engines. The problem with hydrogen is its lower energy density than aircraft fuel. It's the reason why electric jets don't exist

  3. This would probably be for future aircraft not retrofits.

  4. You clearly have no idea what you're talking about.
