Breaking
the hydrogen barrier.

Why hydrogen is the best solution to decarbonize aviation

Zero-emissions using green hydrogen
Inherently safer than kerosene and synfuels
Economically viable
Low-noise profile
Enables new regional air mobility connections through increased range

Our vision

We unlock the era of sustainable air travel by developing the first qualified commercial hydrogen-electric powertrain system for aviation. In over a decade of researching, refining, and testing, we have developed a radically new, zero-emission solution: Hydrogen is converted into electricity in our fuel cell system to power our demonstrator aircraft HY4, proving that zero-emission aviation is within reach.
