Southwest Airlines announces 15-year agreement with Velocys for 219 million gallons of sustainable aviation fuel

Southwest Airlines has announced a 15-year offtake agreement with Velocys Renewables LLC for 219 million gallons of sustainable aviation fuel (SAF).

As announced by Velocys, once blended with conventional jet fuel, the SAF could produce the equivalent of 575 million gallons of net-zero1 fuel and avoid 6.5 million metric tons of CO2 over the term of the agreement. Southwest® plans to begin purchasing SAF from the Velocys Bayou Fuels facility in Natchez, Mississippi, as early as 2026. Additionally, as part of the offtake agreement, Southwest and Velocys have established a long-term strategic relationship, offering Southwest the opportunity to purchase significant volumes of SAF from future Velocys facilities.

Southwest recognizes the critical role that commercially viable SAF will play in the carrier’s strategy to achieve carbon neutrality by 2050. Southwest is one of the most honored airlines in the world and strives to maintain a steadfast focus on a triple bottom line: People, Performance, and Planet.

Velocys is an LSE-listed, international sustainable fuels technology company, traded on the AIM, providing clients with a technology solution to enable the production of negative Carbon Intensity synthetic, drop-in fuels from a variety of waste materials. SAF (‘Sustainable Aviation Fuel’) is the only commercially available, permanent alternative to fossil aviation fuels.

The technology is IP-protected in all major jurisdictions.

Two reference projects in the US and UK (Bayou Fuels and Altalto) are designed to accelerate the adoption and standardize the Velocys proprietary Fischer Tropsch (FT) technology and Bio Energy with CCS solution, BECCS. Velocys is investing in increased capability to deliver its technology to clients, enabling commercial scale SAF production in response to the mandated fuel transition.

Velocys technology pathway is enabling the next generation of low carbon sustainable fuels with significant additional positive air quality impacts.
