Researchers report success in using lignin as a path towards a drop-in 100% sustainable aviation fuel

Lignin makes up the rigid parts of the cell walls of plants. Other parts of plants are used for biofuels, but lignin has been largely overlooked because of the difficulties in breaking it down chemically and converting it into useful products. Researchers at three institutions – the U.S. Department of Energy’s National Renewable Energy Laboratory , the Massachusetts Institute of Technology , and Washington State University – report success in using lignin as a path toward a drop-in 100% sustainable aviation fuel.
Jet fuel is a blended mixture of different hydrocarbon molecules, including aromatics and cycloalkanes. Current commercialized technologies do not produce those components to qualify for a 100% SAF. Instead, SAF blendstocks are combined with conventional hydrocarbon fuels. As the largest source of renewable aromatics in nature, lignin could hold the answer to achieving a complete bio-based jet fuel.
