Our Vision

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