DOE publishes research roadmap for developing cleaner fuels

The U.S. Department of Energy (DOE) today released an ambitious new research agenda for the development of cellulosic ethanol as an alternative to gasoline. The 200-page scientific "roadmap" cites recent advances in biotechnology that have made cost-effective production of ethanol from cellulose, or inedible plant fiber, an attainable goal. The report outlines a detailed research plan for developing new technologies to transform cellulosic ethanol--a renewable, cleaner-burning, and carbon-neutral alternative to gasoline--into an economically viable transportation fuel

"Cellulosic ethanol has the potential to be a major source for transportation fuel for America's energy future," Under Secretary for Science Raymond L. Orbach said. "Low production cost and high efficiency require transformational changes in processing cellulose to ethanol. DOE's Genomics: GTL program is poised to help do just that."

The roadmap responds directly to the goal recently announced by Secretary of Energy Samuel W. Bodman of displacing 30 percent of 2004 transportation fuel consumption with biofuels by 2030. This goal was set in response to the President's Advanced Energy Initiative.

The roadmap identifies the research required for overcoming challenges to the large-scale production of cellulosic ethanol to help meet this goal, including maximizing biomass feedstock productivity, developing better processes by which to break down cellulosic materials into sugars, and optimizing the fermentation process to convert sugars to ethanol. Cellulosic ethanol is derived from the fibrous, woody and generally inedible portions of plant matter (biomass).

The focus of the research plan is to use advances in biotechnology -- first developed in the Human Genome Project and continued in the Genomics: GTL program in the Department's Office of Science -- to jump-start a new fuel industry whose products can be transported, stored and distributed with only modest modification
