The U.S. Department of Energy (DOE) today announced the release of its latest Pathways to Commercial Liftoff report, which underscores the near-term potential for sustainable aviation fuel (SAF) to meaningfully decarbonize the aviation sector. “Pathways to Commercial Liftoff: Sustainable Aviation Fuel ” analyzes the technical and commercial readiness of several SAF production pathways and highlights tangible, actionable steps that both the public and private sector can take to make the United States a global leader in SAF production as soon as 2030.

“With the aviation sector growing each year, there is no better time to invest in solutions that are both technologically and commercially ready today,” said U.S Secretary of Energy Jennifer M. Granholm. “The latest in DOE’s Liftoff series, this report lays out the critical innovations and investments needed to drive down costs and further scale SAF production—paving the way for a cleaner, more competitive aviation sector that will benefit communities and businesses nationwide.”

Thanks, Jaggu. Article shows hydrogenation of fats and oils is most economical but we know supplies are not large enough.

Fermentation ethanol is much smaller but more available and in the same price range. Article mention corn for ethanol. That is controversial, but cellulosic ethanol from corn stover or better waste paper has much potential (if they can make it practical).

Fischer Tropsh is mentioned but very high pressure required makes it unlikely unless low pressure catalysts can be found.

Clean jet fuel, ie SAF, seems to be one if the most difficult challenges. Electric airplanes are unlikely. Hydrogen fuel is not mentioned but might be viable as jet fuel if costs can be reduced.
