Joby’s hydrogen-electric air taxi demonstrator has completed a landmark 523 mile flight, with water as the only by-product.

The aircraft, which takes off and lands vertically, builds on Joby’s successful battery-electric air taxi development program, and demonstrates the potential for hydrogen to unlock emissions-free, regional journeys that don’t require a runway.

The landmark test flight, believed to be the first forward flight of a vertical take off and landing aircraft powered by liquid hydrogen, was completed in June 2024 using a converted Joby pre-production prototype battery-electric aircraft fitted with a liquid hydrogen fuel tank and fuel cell system. It landed with 10% of its hydrogen fuel load remaining.

JoeBen Bevirt, Founder and CEO, Joby, said: “Traveling by air is central to human progress, but we need to find ways to make it cleaner. With our battery-electric air taxi set to fundamentally change the way we move around cities, we’re excited to now be building a technology stack that could redefine regional travel using hydrogen-electric aircraft.

“Imagine being able to fly from San Francisco to San Diego, Boston to Baltimore, or Nashville to New Orleans without the need to go to an airport and with no emissions except water. That world is closer than ever, and the progress we’ve made towards certifying the battery-electric version of our aircraft gives us a great head start as we look ahead to making hydrogen-electric flight a reality.

“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. In service, we also expect to be able to use the same landing pads, the same operations team, and Joby’s ElevateOS software that will support the commercial operation of our battery-electric aircraft.”

Jacob Wilson, (Acting) Branch Chief, AFWERX Agility Prime, said; “Agility Prime has been very supportive of hydrogen-powered aircraft development and testing as it aligns with the program’s goals to advance transformative vertical lift technologies and broader Department of Defense operational energy goals of energy substitution and diversification, and energy demand reduction.”

Dee Dee Myers, Senior Advisor to California Governor Gavin Newsom and Director of the Governor’s Office of Business and Economic Development, said; “Joby is a stellar example of why California continues to lead the world in clean technology and high-tech manufacturing. Their pioneering work to decarbonize aviation, by advancing battery and now hydrogen fuel cell technology, is helping to fight climate change and create a clean energy future that will improve the lives of all Californians.”

Joby’s hydrogen-electric demonstrator is part of the company’s future technology program and is the result of several years of collaboration between a small team at Joby and H2FLY, Joby’s wholly-owned subsidiary based in Stuttgart, Germany. The converted aircraft previously completed more than 25,000 miles of testing as a battery-electric aircraft at Joby’s base in Marina, CA.

Using the same airframe and overall architecture as Joby’s core, battery-electric aircraft, this demonstrator features a liquid hydrogen fuel tank, designed and built by Joby, which stores up to 40 kilograms of liquid hydrogen, alongside a reduced mass of batteries. Hydrogen is fed into a fuel cell system, designed and built by H2FLY, to produce electricity, water, and heat. The electricity produced by the hydrogen fuel cell powers the six electric motors on the Joby aircraft, with the batteries providing additional power primarily during take-off and landing.

Joby’s H2FLY team used similar technology to complete another record-breaking flight in September 2023, when they flew the world’s first piloted flight of a conventional liquid hydrogen-electric aircraft using their fuel cell technology.

Joby plans to start commercial operations as soon as 2025, using its battery-electric air taxi.
