This includes agreements with ten airline companies for the delivery of 916 million gallons of blended sustainable aviation fuel (SAF).
The contracts were signed with Delta Air Lines, Jet Blue Airlines, as well as with oneworld Alliance members including American Airlines, Alaska Airlines, British Airways, Cathay Pacific, Finnair, Iberia, Japan Airlines and Qantas.
Collectively valued at nearly $3.8bn, this contract will see Aemetis supplying the green fuel for seven to ten years.
SAF will be delivered to San Francisco International Airport and Los Angeles International Airport as blended fuel.
The blended SAF consists of 40% of ‘neat’ sustainable aviation fuel and 60% petroleum jet fuel.
Earlier, Aemetis signed a supply agreement with a major travel stop chain for 450 million gallons of RD, which will be delivered to Northern California truck fuelling locations.
SAF and RD will be produced at the Aemetis production plant in Riverbank, California.
The facility is currently in the development phase.
Aemetis founder, chairman and CEO Eric McAfee said: “Sustainable aviation fuel has a vital role in meeting aviation’s decarbonisation targets, so we are pleased to complete another milestone in the drive toward SAF use at a commercial scale.
“The Aemetis plant process design for the Riverbank plant utilises renewable oils, renewable hydrogen and renewable power to produce advanced renewable fuels that reduce greenhouse gas emissions and improve air quality.”
