Since the first flight using sustainable aviation fuel (SAF) took off in 2008, a lot of progress has been made. Below is a snapshot of what is happening in the field of sustainable aviation fuel today.
Commercial flights have been operated using sustainable aviation fuel since 2011 (updated daily)
Number of airports currently regularly supplied with SAF
Total amount of fuel demand that is possible to be covered by sustainable aviation fuel by 2025
Gallons of sustainable aviation fuel in current forward purchase agreements by airlines
Airlines have agreed significant off-take agreements to purchase sustainable aviation fuel
Approved pathways for producing sustainable aviation fuel so far
Regular sustainable aviation fuel (SAF) supply is currently available at Brisbane, Oslo, Los Angeles, Stockholm and Bergen airports.
While the use of sustainable aviation fuel is still relatively low compared to traditional jet fuel, a number of airlines have shown real leadership in driving the use of SAF forward by signing significant forward purchase agreements. These do not include the many airlines that have undertaken one-off or multiple SAF flights. This page has a list of all those special passenger flights from 2011 when the fuel was certified for commercial use.
Sustainable aviation fuel can now be made through five different processes, all internationally approved. It is expected that more of these ‘pathways’ will be approved in the coming years.
|Pathways and processes||Feedstock options||Producers using the pathway||Date of Approval||Current blending Limit|
|Fischer-Tropsch Synthetic Paraffinic Kerosene (FT-SPK)||biomass (forestry residues, grasses, municipal solid waste)||2009||up to 50%|
|Hydroprocessed Esters and Fatty Acids (HEFA-SPK)||algae, jatropha, camelina||Alt Air||2011||up to 50%|
|Hydroprocessed Fermented Sugars to Synthetic Isoparaffins (HFS-SIP)||microbial conversion of sugars to hydrocarbon||Amyris||2014||
up to 10%
|FT-SPK with aromatics (FT-SPK/A)||renewable biomass such as municipal solid waste, agricultural wastes and forestry residues, wood and energy crops||2015||up to 50%|
|Alcohol-to-Jet Synthetic Paraffinic Kerosene (ATJ-SPK) [isobutanol]||agricultural waste products (stover, grasses, forestry slash, crop straws)||Gevo||2016||up to 30%|
|Alcohol-to-Jet Synthetic Paraffinic Kerosene (ATJ-SPK) [ethanol]||agricultural waste products (stover, grasses, forestry slash, crop straws)||Lanzatech||2018||up to 50%|
