Sustainable Aviation Fuel: Soaring Over the Blendwall - 2023

This report assesses SAF production pathways in terms of their technical, economic, and carbon intensity aspects, in line with increasing pressure to decarbonize—along with a key focus on fuel blends that will allow surpassing the existing blendwalls (a potential barrier to net zero ambitions). Key technologies covered at the cost of production level include integration of key pathways for producing paraffins, isoparaffins, and aromatic blendstocks, and blending into a finished product that does not require blending with a fossil fuel. These routes include HVO, ETJ, MTJ, FT, MTA, ETA, as well as traditional refining units with renewable feeds such as isomerization, alkylation, FCC, etc.
