## Southwest Airlines signs purchase agreement with Red Rock Biofuels for renewable jet fuel from forest residues; ~3M gallons per year

##### 24 September 2014

Southwest Airlines has signed an agreement with Red Rock Biofuels LLC (RRB) to purchase low carbon renewable jet fuel, made using forest residues that will help reduce the risk of destructive wildfires in the Western United States. The airline’s agreement with RRB covers the purchase of approximately three million gallons per year. The blended product will be used at Southwest’s Bay Area operations with first delivery expected in 2016.

RRB’s first plant will convert approximately 140,000 dry tons of woody biomass feedstock into at least 12 million gallons per year of renewable jet, diesel, and naphtha fuels. The company recently received a $70-million grant under phase 2 of the US Defense Production Act Title III Advanced Drop-in Biofuels project for construction of the facility, which will also produce mil-spec fuels. (Earlier post.) In July 2013, Red Rock Biofuels was awarded$4.1 million under phase 1 of the same program to conduct detailed engineering for the BTL facility, which is now complete.

The Red Rock process begins with the gasification of woody biomass to produce synthesis gas, which is then is cleaned and sent to a Fischer-Tropsch unit where it is converted to liquid hydrocarbons. Hydroprocessing refines the liquid hydrocarbons to produce jet, diesel, and naphtha fuels.

Red Rock’s gas-to-liquids technology partner is Velocys.

Our commitment to sustainability and efficient operations led us on a search for a viable biofuel that uses a sustainable feedstock with a high rate of success. Red Rock Biofuel’s technology, economics, and approved use made entering into an agreement for purchase a win-win situation.
