Programme

Andreas Bodén is the moderator for the session on Hydrogen flights and starts the session by discussing the opportunities and obstacles for larger implementation of emission-free flying and what developments are taking place today for implementation in larger aircrafts.

Simon will talk about GKN Aerospace activities around the H2Gear project that intends to address the topic of Hydrogen Electric Propulsion (H2EP), as studied under the Hybrid Hydrogen Electric Architecture (H2GEAR) program. This system uses hydrogen fuel cells powered by liquid hydrogen, leveraging its energy capacity and cooling benefits. Aspects of how a cryogenically cooled power train can boost energy conversion and reduce system mass, as well as the choices involved in designing a safe, effective powertrain for a conceptual aircraft will be addressed.

Learn about the latest research results in hydrogen research from Chalmers University of Technology together with Tomas Grönstedt. He will talk about the technology and potential of hydrogen preheating and its integration with the turbofan engine, as well as the performance, challenges, and conditions of future hydrogen aircraft. 

Flying with liquid hydrogen as a fuel is a necessity for the future fossil-free aviation industry. Therefore, the long-term infrastructure of airports with liquid hydrogen must be planned using realistic scenarios and forecasts. In the ongoing FlyH2UME project, the establishment of a hydrogen plant at Umeå Airport will be studied and planned, including safety requirements and the possibility of scaling up. The project's “blueprint” can be used as a model for other airports' establishment of hydrogen aircraft.
