RedRock Biofuels to supply 3M gallons/year of renewable jet fuel to FedEx through 2024

July 21, 2015

Red Rock Biofuels LLC will produce approximately three million gallons of low-carbon, renewable jet fuel per year for FedEx Express, a subsidiary of FedEx Corporation. The agreement runs through 2024, with first delivery expected in 2017. FedEx joins Southwest Airlines, which signed a purchase agreement with RedRock in November 2014 for about 3 million gallons per year, in purchasing Red Rock’s total planned available volume of jet fuel. (Earlier post.)

Red Rock’s first refinery, funded in part by a $70-million Title III DPA grant from the U.S. Departments of Agriculture, Energy and Navy, is scheduled to break ground this fall in Lakeview, Ore. and will convert approximately 140,000 dry tons of woody biomass into 15 million gallons per year of renewable jet, diesel and naphtha fuels.

United Airlines invests $30M in Fulcrum BioEnergy; renewable jet fuel offtake agreement, potential joint development of production

June 30, 2015

United Airlines made a $30-million equity investment in US-based Fulcrum BioEnergy, Inc., the developer of a process for converting municipal solid waste into low-cost sustainable aviation biofuel. (Earlier post.) The investment is so far the largest single investment by a US airline in alternative fuels.

In addition to the equity investment, United and Fulcrum have entered into an agreement that contemplates the joint development of up to five projects located near United’s hubs expected to have the potential to produce up to 180 million gallons of fuel per year.

Kyoto team develops two-stage process for direct liquefaction of low-rank coal and biomass under mild conditions

May 11, 2015

Researchers at Kyoto University in Japan have proposed a novel two-stage process to convert low-rank coals or biomass wastes under mild conditions to high-quality liquid fuel. A paper describing the process, which combines a degradative solvent extraction method they had developed earlier with the liquefaction of the resulting soluble, appears in the ACS journal Energy & Fuels.

One of the issues hampering the development of direct liquefaction of low-grade carbonaceous resources—such as low-rank coals and biomass wastes—to produce liquid fuel is their oxygen content. In low rank coals, cross-linking reactions among oxygen functional groups form large-molecular-weight compounds at temperatures lower than the liquefaction temperature; the oxygen-functional-group-derived cross-links may change to stronger carbon−carbon covalent linkages, suppressing the formation of light hydrocarbons.

University of Adelaide team exploring novel configuration for solar hybridized coal-to-liquids process

Researchers at the University of Adelaide (Australia) are proposing a novel configuration of a hybridized concentrated solar thermal (CST) dual fluidized bed (DFB) gasification process for Fischer–Tropsch liquids (FTL) fuels production. In their investigation of the process, reported in a paper in the ACS journal Energy & Fuels, they used lignite as the feedstock (Solar hybridized coal to liquids, SCTL), although the process could also be used with biomass.

Although fuel products produced via the Fischer-Tropsch process are high quality (free of sulfur, nitrogen and other contaminants found in petroleum-derived products), and coal is a plentiful and low-cost feedstock, the very high greenhouse gas emissions from coal-to-liquids production processes are a major barrier. As one approach to reducing the overall carbon intensity of FT fuels, there is growing interest in introducing concentrated solar power as a heat source into the gasification process.

New UK Energy & Fuels 2050 transportation roadmap highlights important role of drop-in fuels and power-to-gas

March 23, 2015

Professor Neville Jackson, Ricardo’s chief technology and innovation officer, presented the results of a research project carried out by the Automotive Council UK to establish a long-term (to 2050) transition from current gasoline and diesel fuels to a majority renewable energy portfolio. Inputs to the new Energy & Fuels Roadmap included recent UK & EU studies on automotive technologies, as well as roadmaps for passenger cars, commercial vehicles and internal combustion engines previously published by the Automotive Cuncil.

The research, presented at last week’s Open Forum organized by the Society of Motor Manufacturers and Traders (SMMT) in London, aimed to create a high level consensus view for the future of transport energy in the UK. Chaired by Professor Jackson of Ricardo, the research team that produced the report was made up of representatives drawn from a wide range of industry stakeholder organizations including BP, Shell, Jaguar LandRover, Caterpillar, the Energy Technologies Institute, the Low Carbon Vehicle Partnership, E4tech, Element Energy and Associated British Foods.

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

September 24, 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.
