Turbotech, Safran, and Air Liquide have completed groundbreaking ground tests for a liquid hydrogen-fueled gas turbine engine designed for the light aviation market at Air Liquide’s Grenoble Technologies Campus in France. This achievement is part of the BeautHyFuel project, aimed at exploring hydrogen propulsion solutions for light aircraft. Supported by the French Civil Aviation Authority as part of the post-Covid stimulus program, BeautHyFuel is a collaborative effort led by Turbotech and Elixir Aviation in partnership with Safran, Air Liquide, and Daher. The recent successful demonstration tested a hydrogen-fueled gas turbine aeroengine based on an ultra-efficient regenerative cycle fed by a liquid hydrogen tank. This milestone followed an initial test phase using gaseous hydrogen fuel in January 2024. The project aims to achieve energy density similar to conventional fuels while considering retrofit, operability, and certification constraints for a cryogenic hydrogen propulsion system, with a special focus on light aviation. The BeautHyFuel project benefits from the combined expertise of Turbotech, Safran, Air Liquide, Elixir Aviation, and Daher, with a shared goal of designing and testing a hydrogen propulsion system for light aviation. Safran highlighted the successful integration of their technology with Air Liquide's cryogenic storage system to demonstrate a high-tech propulsion solution with zero carbon emissions, suitable for light aircraft. The French government's support for BeautHyFuel contributes to the country's post-pandemic stimulus program and aligns with Safran's ongoing efforts to address greenhouse gas emissions in the aviation sector. Safran's dedication to environmental priorities and sustainable innovation further reinforces the company's commitment to creating a more environmentally friendly and accessible air transport system.
