Joby Aviation, known for developing electric vertical takeoff and landing (eVTOL) aircraft, has unveiled a hydrogen-powered version of its air taxi for city-to-city travel. The company's hydrogen-electric, vertical takeoff and landing (hVTOL) demonstrator recently completed a successful 532-mile flight above Marina, California. The aircraft landed with over 10 percent of its hydrogen fuel remaining, producing only water as a byproduct. Joby sees hydrogen as a key component of its future plans, aiming to redefine regional travel with hydrogen-electric aircraft. By using hydrogen, Joby plans to increase the potential range and payload for electric aircraft, focusing on regional air mobility (RAM) in addition to urban air mobility (UAM). The hydrogen-electric model incorporates technology from Joby's subsidiary H2FLY, enabling longer flights with a greater payload while emitting only water. The company's initiatives are supported by the U.S. Air Force's Agility Prime division, emphasizing the importance of hydrogen-powered aircraft development. Joby also envisions autonomous flight capabilities, with plans to integrate self-flying technology acquired through collaborations and acquisitions. With commercial operations expected to commence in 2025, Joby aims to launch its flagship battery-electric air taxi in partnership with Delta Air Lines in cities like New York and Los Angeles. The company's innovative approach to sustainable aviation reflects a positive outlook on the potential of hydrogen technology in the industry.
