## DOE Awards $22.6M Grant to Rentech and ClearFuels Integrated Bio-Refinery Project ##### 25 January 2010 The Rentech, Inc. and ClearFuels Technology Inc. project to construct a biomass gasifier at Rentech’s Energy Technology Center (RETC) in Denver has been awarded a conditional$22.6-million grant from the US Department of Energy (DOE). The gasifier will be integrated with Rentech’s Product Demonstration Unit (PDU) for the production of renewable synthetic fuels from biomass.

The conditional award follows the DOE’s selection of the project in December 2009 to receive funds under the American Recovery and Reinvestment Act to validate refining technologies and help lay the foundation for full commercial-scale development of an advanced bio-fuels industry in the United States. (Earlier post.) The award is conditional upon final approval of the application and any supplemental information as well as completion of negotiations.

The grant award will be used to manufacture and install at RETC a 20 ton-per-day ClearFuels biomass gasifier designed to produce synthesis gas from various wood waste and sugar cane bagasse feedstocks. The gasifier will be integrated with Rentech’s existing PDU at the site, which uses the Rentech Process and UOP’s upgrading technologies to produce renewable drop-in synthetic jet and diesel fuels at demonstration scale.

This joint demonstration of an integrated bio-refinery is anticipated to be completed in late 2011 and will lead to the final design basis for commercial facilities that are expected to use the combined technologies. The proposed team for the demonstration project includes ClearFuels, Rentech, URS, Linde/Hydro-Chem, Hawaiian Electric Company, National Renewable Energy Lab and Hawaii Natural Energy Institute.

Rentech has a 25% strategic ownership interest in ClearFuels, which has begun development of multiple commercial-scale biomass-to-energy projects in the southeastern United States, Hawaii and internationally. These projects are expected to use an integrated ClearFuels-Rentech design and be co-located at biomass processing facilities.
