From June 1, 2021, airlines will also be able to refuel with Sustainable Aviation Fuel (SAF) at Munich Airport. After a thorough technical inspection, the airport's tank farm is now being opened for climate-friendly fuels of the future. This means that sustainable fuels, so-called "Sustainable Aviation Fuels" (SAF), can now be delivered, stored and refueled at Munich Airport, provided they meet the relevant quality specifications for Jet-A1 aviation fuel. In the tank farm, which is supplied with fuel by various oil companies on behalf of the airlines, deliveries of SAF blends, i.e. conventional kerosene with an admixture of green fuels, are also permitted. Flughafen München GmbH (FMG) is the owner of the entire tank infrastructure, which extends from the tank farm via an underground pipe system covering around 17 kilometers to the aircraft parking positions. The operator of the tank farm is Skytanking Munich GmbH & Co. KG, which ensures the quality control of the fuels delivered and, together with other fuel service providers, is operationally responsible for refueling the aircraft. The SAF fuels used today are mostly obtained from biomass, i.e. from renewable raw materials, so-called "Biomass to Liquid (BtL)" fuels. In the future, however, synthetically produced kerosene will also be available on the market, so-called "Power to Liquid (PtL)" fuels, which are produced by electrolysis using water, CO2 and renewable electricity. Even if the same amount of CO2 emissions are released when SAF is burned as with fossil kerosene, the decisive improvement comes from the production process itself: CO2 is required for production, which is almost completely converted into fuel in this process. This in turn results in
