Study on infrastructural requirements for enabling green hydrogen as an aviation fuel

The use of more sustainable energy carriers represents a major lever for reducing aviation’s climate impact. Among them, liquefied green hydrogen is considered a promising option due to its high emission reduction potential. Its properties, however, differ fundamentally from the tried and trusted kerosene. The adoption of liquid hydrogen as an aviation fuel is, therefore, associated with significant technological and infrastructural challenges – not only when it comes to its integration in the aircraft, but also its storage and handling at the airport. The model-based assessment of the latter is among Bauhaus Luftfahrt’s hydrogen aviation activities and represents one of its contributions to the multi-partner 328H2-FC project funded by the Federal Ministry for Economic Affairs and Climate Action, which is looking into hydrogen fuel cell systems in the megawatt range for the application in a regional aircraft.
