By 2022, the U.S. EPA expects the domestic biofuels industry to produce more than 32 billion gallons per year of renewable fuel. However, less than half of that fuel is expected to be corn-based ethanol. The majority, 16 billion gallons, will be cellulosic biofuel. The Energy Independence and Security Act of 2007 defines cellulosic biofuel as renewable fuel produced from any cellulose, hemicelluloses, or lignin that is derived from renewable biomass and has life-cycle greenhouse gas (GHG) emissions that are at least 60 percent less than the baseline life-cycle GHG emissions. The EPA predicts that, in the long run, those 16 billion gallons of cellulosic biofuel will be cellulosic ethanol. However, EISA’s definition for cellulosic biofuel leaves open the possibility that the mandate can be met by other fuels.

Federal Investments
The goal of ultimately producing billions of gallons of cellulosic biofuel has a hefty price tag. Between 2002 and 2008, the U.S. DOE’s Energy Efficiency and Renewable Energy Biomass Program, established to develop and demonstrate biomass feedstock and conversion technologies for integrated biorefineries and to ensure cellulosic ethanol can be produced cost-effectively by 2012, was allocated more than $800 million in federal funding. Since 2007, the DOE has announced more than $1 billion in multi-year investments in cellulosic biorefineries and since 2006 the USDA has invested almost $600 million to develop biofuel technology.

The bulk of the DOE’s investments began in February 2007 when it announced plans to invest $385 million in six biorefinery projects over four years for a total cellulosic ethanol production capacity of 131 MMgy. Combined with the industry cost share, the projects equated to more than $1.2 billion in investments. Projects identified for funding included an 11 MMgy Abengoa Bioenergy SA plant in Kansas, a 14 MMgy Alico Inc. plant in Florida, a 19 MMgy BlueFire Ethanol Fuels Inc. facility in California, a 30 MMgy Poet LLC plant in Iowa, an 18 MMgy Iogen Corp. plant in Idaho, and a 100 MMgy Range Fuels Inc. plant in Georgia.

In May 2007, the DOE announced it would provide up to $200 million over five years to support the development of small-scale cellulosic biorefineries. The first $114 million was allotted in January 2008 for four projects. The companies identified for funding included ICM Inc., Lignol Energy Corp., Pacific Ethanol Inc., and Stora Enso Oyj. The remaining $86 million was allotted to RSE Pulp & Chemical LLC, Mascoma Corp. and Ecofin LLC in April 2008. In July 2008, the DOE announced an additional $40 million investment for two more companies - Flambeau River Biofuels LLC for its project in Wisconsin and Verenium Corp. for its demonstration-scale facility in Louisiana. Seven of the nine plants were funded for cellulosic ethanol and two for cellulosic diesel.

On the research side, both the DOE and the USDA also provided funding to companies and universities. In March 2007, the DOE invested $23 million in five projects to develop highly efficient fermentative organisms to convert biomass material to ethanol; the companies and organizations identified for funding included Cargill Inc., Verenium, E. I. du Pont de Nemours and Co., Mascoma, and Purdue University. In June 2007, the DOE and USDA together awarded $8.3 million to 10 universities for biomass genomic research. During that month, the DOE also announced a $375 million investment in three new bioenergy research centers, including the DOE BioEnergy Science Center, the DOE Great Lakes Bioenergy Research Center, and the DOE Joint BioEnergy Institute.

To close out the year, the DOE awarded $7.7 million in December 2007 to four projects to demonstrate the thermochemical conversion process of biomass-to-biofuels. Then, in February 2008, the DOE invested $33.8 million in four projects to develop improved enzyme systems to convert cellulosic material into sugars suitable for the production of biofuels. The companies identified for funding included DSM Innovation Center Inc. (a partner with Abengoa), Genencor, a division of Danisco A/S, Novozymes A/S, and Verenium.

In March 2008, the DOE and USDA awarded $18 million to 18 universities and research institutes to develop biomass-based products, including biofuels.


To meet renewable fuel standard targets, the U.S. EPA says cellulosic ethanol plant startups must begin in earnest with a few small plants during 2010-'11 and must continue at an increasing pace thereafter with larger plants. The EPA says the rate of growth for the cellulosic ethanol industry should be similar to that of the corn starch-based ethanol industry in recent years.

Finally, in May 2009, the DOE announced that it would provide $786.5 million from the American Recovery and Reinvestment Act to accelerate advanced biofuels research and development and to provide additional funding for commercial-scale biorefinery demonstration projects. Of the total, $480 million will be distributed among 10 to 20 projects for pilot- or demonstration-scale integrated biorefineries that produce advanced biofuels, bioproducts, and heat and power in an integrated system, which must be operational within three years. In addition, $176.5 million will be used to increase the federal funding ceiling on two or more demonstration- or commercial-scale biorefinery projects that were selected and awarded funds within the past two years. Also, $110 million will be used to support new research. Finally, $20 million has been set aside for optimizing flexible fuel vehicle technology, evaluating the impact of higher ethanol blends on conventional vehicles, and upgrading refueling stations to be compatible with ethanol blends up to E85.
