Sustainable Aviation Fuel: Review of Technical Pathways vii ASTM International (ASTM) D7566-approved SAFs for use in up to 10% to 50% blends. Credit: Dennis Schroeder, NREL. Although there are currently seven ASTM-approved SAF production pathways, availability of the required feedstock and increased costs compared to conventional jet fuels pose major challenges for a fast market uptake.
And ASTM, over time, has approved seven SAF production pathways, and I'm sure we'll continue to see more technology pathways approved over time. The first ASTM approved process, listed as Annex A1 of D7566, was the FischerTropsch process, in 2009, with a blending limit of 50%. The pathways comprised ASTM-approved processes (HEFA, ATJ, and FT) and strategic feedstocks such as sugarcane (SC), soybean, palm, used cooking oil (UCO), beef tallow, agricultural and forestry residues (FR), and steel off-gases. ASTM D7566 is updated regularly as new manufacturing processes are A century later, the Fischer-Tropsch process is one of the main ASTM-approved methods for producing SAF. Multiple pathways have been developed and received ASTM approval to convert a variety of feedstocks into SAF, each with strengths and weaknesses that vary with conversion technology, feedstock, and production location. There is an increasing amount of discussion on the use and approval of a 100% SAF that does not need to be blended, he says. Other federal agencies will also aid in reaching the administrations SAF goals. In fact, it can take a producer as many as five years and $15 million to secure approval for a new pathway.
