Turbotech, Safran, and Air Liquide have successfully conducted ground tests on the first liquid hydrogen-fueled gas turbine engine for the light aviation market at Air Liquide's Grenoble Technologies Campus in France. This achievement is part of the BeautHyFuel project, which aims to explore hydrogen propulsion solutions for light aircraft. The project, supported by the French Civil Aviation Authority as part of the country's post-Covid stimulus program, involves Turbotech, Elixir Aviation, Safran, Air Liquide, and Daher. The successful ground demonstration testing of the hydrogen-fueled gas turbine aeroengine marks a significant step in the transition to fully decarbonized aircraft propulsion, showcasing the feasibility of achieving zero carbon emissions in flight with hydrogen technology. The integration of a cryogenic storage system by Air Liquide has demonstrated the high energy density required for aircraft applications. Pierre-Alain Lambert from Safran highlighted the successful coupling of technology with cryogenic storage, emphasizing the potential for high-tech propulsion solutions with zero carbon emissions. Xavier Traversac from Air Liquide stressed the importance of collaboration for decarbonization and the role of hydrogen in the energy transition. The BeautHyFuel joint research project brings together industry expertise to design and ground test a hydrogen propulsion system for light aviation. Supported by the French government, the project complements initiatives to reduce greenhouse gas emissions in air transport, showcasing the commitment to innovation and sustainability in the aerospace sector.
