Future of Green, Zero Emissions Flying

A major, zero emissions flying project is underway in Germany to open the global skies to hydrogen-powered planes.  Germany's H2Fly, which is a global leader in hydrogen propulsion systems, is performing a series of flight tests on its hydrogen plane with its advanced powertrain that pumps out 130 kW of power.  Testing of the twin boom Hy4 aircraft is taking place at an airport in Stuttgart, Germany and will continue through mid-2022.  H2Fly and its partner Duetsche Aircraft will then further refine the hydrogen powered flying system. H2Fly believes that their hydrogen propulsion system can be adapted for powering a range of aircraft, including large ones capable of carrying 100 passengers and also small, 4 to 8 seat eVTOLs (electric, vertical takeoff and landing vehicles).

Hydrogen Powered Flights into the Future

The HY4 is H2Fly's seventh generation aircraft under development. The company says that it has upgraded and improved the vehicle's controls, operational procedures, redundancy systems and insulation. It has already undergone more than 70 successful test flights. The company believes the hydrogen propulsion system has a potential range of 1,563 miles. H2Fly is also working with Stuttgart Airport to develop the proper infrastructure and procedures needed to support hydrogen powered aircraft.  This major development project for hydrogen planes is being supported by the German government.

Next Steps Toward Takeoff

First flights for the hydrogen plane capable of carrying 40 passengers will take place in 2025.  The H2Fly powertrain will be integrated into a Duetsche Aircraft, modernized Dornier 328 turboprop.  The powertrain will produce a total power output of 1.5 MW to sustain the aircraft's flight and operations.  The company in the long term expects to use a different airframe to maximize performance, such as a blended wing airframe.  They also envision a powertrain with 6 MW capable of powering a large plane with 100 passengers.  H2Fly expects their hydrogen plane to be operational in 2028 and in widespread use by 2030.  The German company is providing a big push forward in the future of hydrogen powered, zero emissions flying.
