SAN FRANCISCO, Sept. 20 -- Amazon announced on Tuesday that it has signed an agreement with renewable fuels technology company Infinium to begin powering Amazon's transportation fleet with ultra-low carbon electrofuels beginning in 2023.

Infinium is expected to initially supply enough electrofuels, which are a fossil-based fuel alternative created with carbon waste and renewable power, to begin powering Amazon trucks in lieu of diesel fuel for approximately 5 million miles of travel per year, the company said, adding that the agreement is another step forward in its commitment to transitioning its transportation network away from fossil fuels.

Amazon plans to initially use the electrofuels in trucks in its middle mile fleet in Southern California. Amazon's middle mile fleet is responsible for moving customer orders from its vendors and fulfillment centers to its network of sortation and delivery stations.

To start, Infinium plans to build one of the world's first electrofuels-production facilities in Texas. The facility will use renewable-power-generated green hydrogen and approximately 18,000 tons of recycled carbon waste per year to create the electrofuels.

Amazon previously invested in Infinium through The Climate Pledge Fund, Amazon's 2-billion-U.S.-dollar venture investment program that specifically invests in companies building technologies, products, and services that can help Amazon and others accelerate the path toward net-zero carbon future. Amazon has announced investments in a total of 18 companies through The Climate Pledge Fund to date, according to the company.

Amazon is committed to reaching net-zero carbon by 2040 as part of its commitment to The Climate Pledge, and will continue to take real business action to decarbonize its operations.
