Airline EasyJet and Aircraft Engine maker Rolls-Royce announced that they have successfully tested a hydrogen-powered aircraft engine, which is described as the World’s First for aviation. They had set a new aviation milestone with the world’s first run of a modern aero engine on hydrogen in a test carried out on land earlier this month. The company tested a turboprop fan engine that is used a small regional flights aircraft. Green hydrogen for the tests had been generated using tidal and wind energy from Orkney Islands, Scotland. Rolls-Royce is eventually hoping to conduct a full-scale ground test of a Pearl 15 jet engine.
