Barthle: Energy transition in the transport sector requires alternative aviation fuels

Alternative aviation fuels could already partly replace fossil jet fuel. Their use would enable aviation, a sector that depends on liquid fuels, to actively contribute to the energy transition. However, this requires the construction of advanced bio refineries in Germany, which are lacking so far. This is the conclusion of a study by aireg that was commissioned by the Federal Ministry of Transport and Digital Infrastructure and that the aireg board presented to Parliamentary State Secretary Norbert Barthle today.


“The long-term growth prospects of aviation in Germany depend on our ability to incorporate energy-efficient as well as climate- and environmentally-friendly solutions. Alternative aviation fuels offer promising results and, in addition to technological innovations and the emissions trading scheme, are able to contribute to decouple transport performance and emissions in the future. “

Since 2011, three synthetic aviation fuels technologies have been certified, with more to follow. The study shows that cost advantages will be associated with the expansion of capacity. Due to the current low price of mineral oil, alternative fuels are not yet competitive.

Siegfried Knecht, Chairman of the board of aireg:
“Our results show that alternative aviation fuels also have other benefits such as higher energy content and less soot output. We therefore give examples of how a market introduction within a few years can succeed in utilizing these advantages. The longer emissions grow, the harder it is to comply with the greenhouse gas emission targets.”

Policy makers and aviation industry intend to stabilize the aviation COemissions at the level of 2020. On a global scale, the UN organization for civil aviation ICAO is currently working on a market-based solution that integrates alternative aviation fuels. The Federal Government supports measures in the transport sector to counter climate change through its Mobility and Fuels Strategy (MKS). Currently, as part of the MKS, a feasibility study for an innovative bio refinery concept is being commissioned.

aireg perceives the study as a confirmation that the missing bio refining capacity represents the biggest obstacle to greater use of alternative aviation fuels in Germany. Further political efforts for more climate protection in aviation should also be
