For French aerospace supplier Safran, decarbonising aviation requires a three-pronged approach: reducing fuel consumption, electrifying aircraft, and transitioning to carbon-neutral fuels.
Parked just outside the Paris Air Lab, the EcoPulse distributed hybrid-electric aircraft demonstrator showcases this ambition. The project — a joint effort by Airbus, Daher, and Safran — is backed by the French Civil Aviation Research Council (CORAC) and co-funded by the French government* and the European Union.
Inside the exhibition, visitors can discover the Open Fan — a new-generation propulsion system that could cut fuel consumption by up to 20%. This technology was developed by CFM International, a 50/50 joint venture between Safran Aircraft Engines and GE Aerospace.
Safran is also working on improving efficiency during ground operations. Its eAPU (electric auxiliary power unit) is designed to generate electricity tailored to the needs of future electrified aircraft, helping to reduce fuel use during taxiing.
Synthetic Fuels First, Hydrogen to Follow
Greening aviation fuels is another key pillar. Safran is a strong proponent of synthetic fuels and is participating in the BeautHyFuel project, backed by the French Civil Aviation Authority (DGAC), alongside partners such as Turbotech, Elixir Aircraft, Air Liquide and Daher. In 2022, Safran also invested in German start-up Ineratec, which develops synthetic aviation fuel (SAF) production units. The first of these units came online at Frankfurt Airport in 2025.
Looking further ahead, Safran is exploring hydrogen-powered aviation through CORAC and the European Clean Aviation programme. Several research projects are already underway, including collaborations with Airbus and France’s ONERA research centre, particularly focusing on the availability of green hydrogen.
