Researchers demonstrate hydrogen as a viable aviation fuel
by Swansea University | June 8, 2026
Researchers from Swansea University are celebrating their role in
a major aviation milestone following the
successful completion of a four-year international program
led by Rolls-Royce and easyJet to demonstrate hydrogen as a viable aviation fuel. The program has culminated in a world-first achievement: a modern aero engine running on 100% hydrogen at full takeoff power, proving the potential of
hydrogen to play a transformative role in future zero-carbon aviation.
Swansea University provided critical materials data to support the development of hydrogen-fueled gas turbines as a core partner in the HYEST (Hydrogen Engine System Technologies) initiative.
As part of the project, Swansea's Institute of Structural Materials (ISM) established new world-class mechanical testing capabilities in two areas previously unexplored by the research group:
cryogenic temperatures
high-pressure hydrogen environments... more
