As part of efforts to decarbonize the general aviation sector, Turbotech, Safran, and Air Liquide have successfully ground-tested a liquid hydrogen-fueled gas turbine engine designed for light aircraft. The test, conducted at Air Liquide’s Grenoble Technologies Campus in France, is part of the ongoing BeautHyFuel project to develop hydrogen propulsion systems for aviation.

The BeautHyFuel program also includes Elixir Aviation and Daher and is supported by the French government, with all testing to date having been conducted in France. The ground test reported on January 13 follows an engine qualification test conducted in January 2024, which involved gaseous hydrogen. This second test phase introduced a cryogenic liquid hydrogen storage system, developed by energy group Air Liquide, to replicate a fully integrated propulsion system suitable for light aircraft.
