Joby Aviation has flown its eVTOL aircraft with a hydrogen-electric propulsion system developed by its German subsidiary H2Fly. The company announced on July 11 that in June its demonstrator aircraft flew 523 miles, which is more than five times the range of the aircraft powered by its standard battery-electric powertrain.

According to Joby, the flight demonstrates the potential for regional eVTOL air services connecting cities, rather than simply flying in and around metropolitan areas. The company said it believes this was the first forward flight of a vertical takeoff and landing aircraft powered by liquid hydrogen.
