Cellulosic Biomass: An Abundant, Secure Energy Source to Reduce
U.S. Dependence on Gasoline

Bioethanol made from cellulosic biomass—the inedible, fibrous portions of plants—offers a renewable, sustainable, and expandable domestic resource to meet the growing demand for transportation fuels and reduce our dependence on oil.

The United States now produces 7 billion gallons of corn-grain ethanol per year, a fraction of the 142 billion gallons of transportation fuel used annually. Cellulosic ethanol has the potential to dramatically increase the availability of ethanol and help meet the national goal of displacing 30% of gasoline by 2030.

Cellulose is the most abundant biological material on earth. The crops used to make cellulosic ethanol (e.g., postharvest corn plants—not corn grain—and switchgrass) can be grown in most states and often on marginal lands. As with ethanol from corn grain, cellulose-based ethanol can be used as a fuel additive to improve gasoline combustion in today’s vehicles. Modest engine modifications are required to use higher blends (85% ethanol). Additionally, the amount of carbon dioxide emitted to the atmosphere from producing and burning ethanol is far less than that released from gasoline.

To accelerate technological breakthroughs, the DOE Genomics:GTL program will establish research centers to target specific DOE mission challenges. Three DOE Bioenergy Research Centers are focused on overcoming biological challenges to cellulosic ethanol production. In addition to ethanol, these centers are exploring ways to produce a new generation of petroleum-like biofuels and other advanced energy products from cellulosic biomass.
