The company has no stated plans to integrate hydrogen fuel cells on its air taxi, but Bevirt gave its subsidiary some praise. JoeBen Bevirt, founder and CEO of Joby, has repeatedly touted the benefits of hydrogen, hinting at the company’s desire to explore it as a fuel source. It said switching to the liquid form of the fuel source will double the HY4’s range from about 405 to 810 nm, a promising sign for a company that hopes to supply hydrogen-electric powertrains for zero-emissions medium- and long-haul commercial flights. Prior to this week’s tests, H2Fly had only flown with pressurized gaseous hydrogen. ![]() The company made four takeoffs from an airfield in Maribor, Slovenia, using cryogenically stored liquid hydrogen to power a hydrogen-electric fuel cell system, which kept the aircraft in the sky for over three hours on one occasion. Joby subsidiary H2Fly on Thursday revealed it completed piloted flights of its four-seater HY4 demonstrator powered by liquid hydrogen, a milestone it says is the world’s first. ![]() This week, that company did something no other firm has done. In 2021, electric vertical takeoff and landing (eVTOL) air taxi developer Joby Aviation secretly acquired a company producing hydrogen aircraft fuel cell systems. ![]()
