In the aviation sector, there is a collective vision for achieving "net-zero" operations by mid-century, aligning with global decarbonization targets such as COP21 and regional goals, such as the EU's "Fit for 55" Package and "ReFuelEU Aviation" directives. Despite this vision, it is acknowledged that the current pace of development and advancements may not be sufficient to meet the set targets within the given timeline. Cognizant of the need for GHG emission reduction in the aviation sector, the German government is actively advocating for measures to decrease overall emissions. This advocacy is anticipated to drive a substantial increase in demand for Sustainable Aviation Fuels (SAFs) in the years to come. The focus extends beyond traditional Power-to-Liquid fuels, with consideration given to the production of biogenic SAFs. The current status of the aviation sector entails a global or country-level analysis of specific requirements for fuels, infrastructure, and regulatory frameworks. While numerous publications delve into SAF production, there is a need for a comprehensive exploration of supply-side constraints, economic considerations, and other sustainability drivers within the sector. To address these gaps, this contribution aims to evaluate the potential of producing biogenic and non-biogenic SAFs in Germany. The analysis will encompass environmental, technical, and commercial aspects of various aviation fuel production pathways, adhering to approved ASTM D7566 standard and expected amendments.
The objective is to provide a thorough understanding of current and future SAF aspirations in Germany. Additionally, this investigation seeks to optimize emissions and costs, identifying potential pathways that may contribute to the decarbonization of aviation in Germany. The focus is on harnessing the potential of the German market to produce SAFs from indigenous biogenic feedstocks and e-fuels from renewable electricity. Importantly, this approach eliminates reliance on international imports of feedstocks or fuels, aligning with the country's commitment to developing a self-reliant energy market that supports its decarbonization targets. The findings underscore certain growth limitations, particularly regarding land use and regulatory frameworks in Germany. These constraints restrict the maximum potential of biogenic fuels to 12% (average) until 2050, with most scenarios falling short of exceeding 10% (average) energy substitution. Therefore, a significant contribution of non-biogenic SAF pathways is expected to meet the German aviation targets.
