e-SAF (electrolytic sustainable aviation fuel) is produced using electricity and is not constrained by biological feedstocks. It is more expensive than bio-feedstock-derived SAF.
Commodities price reporting agency Argus has recently launched the first methanol-to-jet cost indices (weekly calculated prices) for nine major production locations.
This has followed the approval by ASTM International, a US standards organization, for methanol-to-jet as a valid process for making e-SAF (electrolytic SAF), clearing the path for airlines to use it in their decarbonisation programs.
Methanol is an organic chemical compound (also known as methyl alcohol) and is the simplest aliphatic compound (chemical compounds containing carbon that are not aromatic compounds).
