H2FLY, a subsidiary of Joby Aviation, has successfully completed the world’s first piloted flight of a liquid hydrogen-powered electric aircraft. This groundbreaking achievement marks a significant step towards the long-term decarbonization of mid- to long-range aviation. The HY4 demonstrator aircraft, developed by H2FLY, was at the forefront of these test flights. One notable flight lasted over three hours, powered entirely by a hydrogen-electric fuel cell propulsion system and liquid hydrogen. Cryogenically-stored liquid hydrogen offers advantages over gaseous hydrogen, including reduced tank weights and volume. This technological shift has the potential to double the HY4’s flight range from 466 mi (750 … Continue reading H2FLY’s Green Milestone: World’s First Liquid Hydrogen Electric Aircraft Takes Flight!
