Joby Aviation (NYSE: JOBY), a leading developer of eVTOL aircraft, has announced the successful flight of its hydrogen-electric air taxi demonstrator, covering 523 miles with only water as a by-product. 

This aircraft builds on Joby's battery-electric air taxi program and showcases hydrogen's potential for emissions-free, regional travel without runways. The test flight, completed last month, used a modified pre-production battery-electric aircraft with a liquid hydrogen fuel tank and fuel cell system, landing with 10% of its hydrogen fuel remaining.

The aircraft, previously tested as a battery-electric model for over 25,000 miles in Marina, CA, now features a Joby-designed liquid hydrogen fuel tank and fuel cell system designed by H2FLY. The system converts hydrogen into electricity, water, and heat, powering the six electric motors, with batteries providing additional power during takeoff and landing.

JoeBen Bevirt, Founder and CEO of Joby stated: The vast majority of the design, testing and certification work we’ve completed on our battery-electric aircraft carries over to commercializing hydrogen-electric flight.”

Joby Aviation is a California-based transportation company pioneering an all-electric, eVTOL air taxi.
