Hydrogen-electric eVTOL takes off
Joby Aviation, H2FLY’s parent company, has successfully flown a hydrogen-powered vertical takeoff and landing aircraft 523 miles, demonstrating the potential of hydrogen for emission-free regional travel. H2FLY designed and built the proprietary fuel cell system for Joby’s demonstrator as part of the ongoing H2F-175 development program. The landmark test flight is believed to be the first forward flight of a vertical take-off and landing aircraft powered by liquid hydrogen.

Another world’s first: Liquid hydrogen
Laying the final piece of technical ground work before commercial hydrogen-electric aviation can take off, H2FLY together with it’s partner Air Liquide, is the first company to successfully run its hydrogen-electric powertrain on liquid, cryogenic hydrogen.

Breaking the world record
Our hydrogen-electric demonstrator aircraft HY4 sets a record crossing the altitude of 7,000 feet, proving the potential of hydrogen and fuel cells to make sustainable air travel a reality. In the same flight testing campaign, our team realized the world’s first cross-country flight, showcasing that the technology can be embedded in today’s airspace and ground operations.

Demo flights with redundant architecture
The sixth generation of our powertrain is tested in-flight. The long-endurance flight and highly redundant powertrain architecture, prepares us for the coming type certification processes.
2016
HY4 is airborne
The HY4 celebrates its maiden flight. A test campaign of 32 flights over four days proves the scalability of H2FLYs fuel cell powertrain and demonstrates the fast-refueling capability of our hydrogen propulsion system.
