The sustainable fuels offensive is taking shape in air transport. For the first time, an Airbus A319neo carried out on Thursday, October 28 a test flight in the Toulouse region with a Leap engine running on 100% sustainable aviation fuel (SAF in English, for “sustainable aviation fuel”). An alternative energy source favored by aeronautics manufacturers: derived from biomass, food and agricultural waste, they could reduce the carbon footprint of existing aircraft by 80% by taking into account their entire cycle of life. The fuel used during this flight, supplied by Total Energies, was derived from used cooking oils.
Hence the desire of manufacturers to exceed the current rate of incorporation of SAF in aircraft, set at 50% for most certified sectors. Reasons for which Airbus, Dassault Aviation, Safran, ONERA and the Ministry of Transport launched the VOLCAN project, for FLIGHT with New Alternative Carburants, in which the flight of this A319neo is part: these actors seek to analyze the impact a flight carried out with 100% sustainable fuel on the aircraft’s equipment and on its emissions. What engine adaptations must be made? What about emissions and trail formation?
This work, like that carried out by Airbus with Rolls-Royce, aims to promote the deployment of sustainable aviation fuels. As a reminder, air transport is responsible for around 3% of global greenhouse gas emissions. Aircraft and engine manufacturers jointly pursue the ambition to certify aircraft and engines 100% compatible with SAFs by the end of the decade. Democratization which will also depend on the availability of resources and the ability to collect them, as well as the implementation of incentive tools promoting the use of fuels at much higher costs than traditional kerosene.
