This CleanTech Hub focus area will present a selection of Lufthansa Group initiatives on the topic of sustainable aviation fuels, emissions reduction and climate research.
Even though the commonly known fossil kerosene will remain the main fuel in aviation for the next decade, sustainable fuels offer a valuable perspective for the future.
The use of sustainable fuels, so-called Sustainable Aviation Fuels (SAF), results in a closed carbon cycle, as combustion only releases the CO2 that was used in fuel production. SAF is comparable to fossil kerosene in terms of quality and performance, is compatible with conventional engines, and can use existing infrastructure for storage and refueling.
Another longer-term fuel alternative is the use of green hydrogen produced exclusively with renewable energy. Using hydrogen as a fuel would make propulsion carbon-free. However, the use of hydrogen still requires many innovations, such as different tanks, because liquid hydrogen has a larger volume than kerosene and must be stored at extremely low temperatures. Thus, to get commercial aircraft powered by climate-friendly hydrogen into the skies, building the appropriate infrastructure and developing the flying fuel cell, as well as integrating both components into an aircraft, is elementary and still requires a lot of research.
The Lufthansa Group has been a reliable partner of climate research since 1994 and has since equipped several aircraft with special measuring instruments. In addition to carrying passengers, these aircraft are also in the service of climate research.
We invite you to explore a selection of our established projects, initiatives, and ambitions
