A project focused on the design, development, and integration of a powertrain that operates on high-power cryogenic and fuel cell technology for commercial aircraft, demonstrating the feasibility of cryogenic liquid H2 use in aircraft.

A German government-funded collaboration to develop and test a megawatt-range H2-electric fuel cell system. The project involves integrating the H175 system into a Dornier 328 demonstrator aircraft for flight demonstrations.

An EU-funding research program under which H2FLY completed the world's first piloted flight of an electric aircraft powered by liquid H2.

A four-seater hydrogen-powered electric airplane that has set a new altitude record and achieved the first European flight between commercial airports for an H2-powered passenger aircraft.

A new generation of aviation-grade, modular hydrogen fuel cell power units for commercial aircraft. The system can operate at altitudes up to 27,000 feet and is compliant with aircraft ranging from 20 to 80 seats. Multiple units can be combined to upscale for megawatt-class aircraft.

A hydrogen fuel cell-powered testbed aircraft that set an H2-electric passenger aircraft world record. Represents one of six generations of hydrogen fuel cell aircraft technology developed by H2FLY.
