Biofuels can provide viable, sustainable solution to reducing petroleum dependenceFebruary 11, 2009LIVERMORE, Calif. - An in-depth study by Sandia National Laboratories and General Motors Corp. has found that plant and forestry waste and dedicated energy crops could sustainably replace nearly a third of gasoline use by the year 2030. The goal of the "90-Billion Gallon Biofuel Deployment Study" was to assess whether and how a large volume of cellulosic biofuel could be sustainably produced, assuming technical and scientific progress continues at expected rates. The study was conducted over a period of nine months. Researchers assessed the feasibility, implications, limitations, and enablers of annually producing 90 billion gallons of ethanol - sufficient to replace more than 60 billion of the estimated 180 billion gallons of gasoline expected to be used annually by 2030. Ninety billion gallons a year exceeds the U.S. Department of Energy's goal for ethanol production established in 2006. The "90 Billion Gallon Study" assumes 75 billion gallons would be ethanol made from nonfood cellulosic feedstocks and 15 billion gallons from corn-based ethanol. The study examined four sources of biofuels: agricultural residue, such as corn stover and wheat straw; forest residue; dedicated energy crops, including switchgrass; and short rotation woody crops, such as willow and poplar trees. It examines the costs of producing, harvesting, storing and transporting these sources to newly built biorefineries. Key findings Using a newly developed tool known as the Biofuels Deployment Model, or BDM, Sandia researchers determined that 21 billion gallons of cellulosic ethanol could be produced per year by 2022 without displacing current crops. The Renewable Fuels Standard, part of the 2007 Energy Independence and Security Act, calls for ramping up biofuels production to 36 billion gallons a year by 2022. The 90 Billion Gallon Study, which focused only on starch-based and cellulosic ethanol, found that an increase to 90 billion gallons of ethanol could be sustainably achieved by 2030 within real-world economic and environmental parameters. Other findings: Sandia's '90 Billion Gallon Biofuel Deployment Study' concludes that 90 billion gallons per year of biomass-derived ethanol can be produced and distributed with enduring government commitment and continued technological progress . Continued support of R&D and initial commercialization is critical because sustained technological progress and commercial validation is a prerequisite to affordably producing the large volumes of ethanol considered in this study. Policy incentives such as a federal cap and trade program, carbon taxes, excise tax credits and loan guarantees for cellulosic biofuels are important to mitigate the risk of oil market volatility. The domestic investment for biofuels production is projected to be virtually the same as the investment required to sustain long-term domestic petroleum production. Cellulosic biofuels could compete without incentives with oil priced at $90 per barrel, assuming a reduction in total costs as advanced biofuels technologies mature. Large-scale cellulosic biofuel production could be achieved at or below current water consumption levels of petroleum fuels from on-shore oil production and refining. The industrial processes by which nonfood forms of biomass are converted into sugars suitable for production of biofuels were a focus of the study. Sandia's analysis also included land use, water availability, energy used to produce cellulosic biomass, transportation of feedstocks and other potential leverage points for the development and use of cellulosic biofuels. In conducting its research, Sandia utilized models that examined current and future technologies for development of ethanol. Future enhancements to Sandia's BDM are planned, contingent on additional partnerships. Such improvements to the current software tool, says Sandia business development associate Carrie Burchard, would provide an even more comprehensive systems understanding of the biofuels industry.
