Recent Sales Agreements Expand the Impact of Gevo Sustainable Aviation Fuel Around the World

Gevo has been working to spread the word about the impact of its sustainable aviation fuel (SAF). It seems the world is beginning to understand how Gevo is pursuing multiple pathways to commercialize SAF and scale production, including our homegrown isobutanol pathway, as well as ethanol-to-jet pathways. And the message is spreading, if the recent sales agreements with airlines around the world are any indication. After all, the world-class airlines that are coming to us all have emissions-reduction targets built into their sustainability plans. It makes sense for any goals—short term, long-term, and everything in between—since the fuel is expected to diminish the carbon intensity of any flight in which it is used with the same proportion as the fuel in the tank, up to 50 percent blending with fossil-based jet fuel right now according to the standard.

Recent agreements we’ve announced include:

We inked a deal with Finnair for 7 million gallons per year for a five-year period, with an expected value of $192 million. Read the full news release here.

Japan Airlines recently incorporated Gevo SAF into its plans to reduce emissions on flights throughout Asia and around the world. The agreement for 5.3 million gallons per year is for a five-year period. Get the details in this news release.

Additional agreements include Delta Airlines and oneworld® Alliance.

Gevo’s SAF is built from the ground up to be molecularly identical to petroleum-based jet fuel, but because we manufacture it, rather than refining it from a crude product, it meets or exceeds the standards in ASTM D1655 specification:

  • For flash point, the standard stipulates a 38 degrees C minimum, and both typical Jet A-1 and ATJ are well within acceptable range at 48 degrees C.
  • Both also pass the standard for thermal oxidation stability.
  • For freezing point, the standard requires -40 degrees C maximum for Jet A and -47 degrees C for Jet A-1,and Jet A-1 complies with -50 degrees C, while ATJ is -80 degrees C.
  • The energy density standard is 42.8 MJ/kg minimum, and Jet A-1 complies with 42.9 MJ/kg, while ATJ has 43.2 MJ/kg.
  • The total sulfur content standard is 0.3 percent max, while Jet A-1 comes in at 0.05 percent and ATJ rates at less than 0.01 percent.

Gevo has remained focused on sustainability at every stage of production. Gevo has developed two alcohol-to-jet pathways that can utilize various low-carbon feedstocks grown using sustainable agriculture. These feedstocks can then be converted, in some cases, to high-value nutritional products and energy-dense liquid hydrocarbons, including SAF. Gevo’s production processes will incorporate renewable energy, including wind turbines, biogas, and combined heat and power systems (CHP) to increase efficiency and reduce carbon intensity to net-zero levels, which the customer can then pass on through the fuel.
