Joby Aviation, an NYSE-listed eVTOL developer, has announced the completion of its 523-mile eVTOL flight powered by a hydrogen-electric propulsion system. Joby claimed the test flight marked the first occasion of a forward-moving flight using a VTOL aircraft powered by liquid hydrogen.
The test aircraft lifted off with a bespoke tank with the capacity of carrying 40 kg of liquid hydrogen and a lesser number of batteries than the standard eVTOL model. The hydrogen is input into a fuel-cell system developed by the subsidiary H2Fly. The Joby aircraft's six motors are powered by electricity, with the batteries providing additional power, mainly during takeoff and landing. After the flight, the aircraft reportedly had 10% fuel remaining.
Joby's hydrogen system was developed by its subsidiary, a Germany-based startup, H2FLY, which has been working on initiating hydrogen propulsion systems for several years. H2FLY conducted the first-ever piloted flight propelled by liquid hydrogen in September 2023. Joby expects that hydrogen-powered eVTOLs would be able to fly further, connecting more distant locations.
