Energy Independence --The “moonshot” for this generation. Lonnie Ingram*, S. Zhou, K.T. Shanmugam, B.E. Wood, & T. B. Causey Florida Center for Renewable Chemicals and Fuel The University of Florida Replacing Imported Petroleum with Renewable Fuel Ethanol
The US currently needs 200 billion gallons of automotive fuel. This represents half of the total petroleum needed in the US. Over half of the petroleum used in the US is imported. Therefore – Each year, the equivalent of all US automotive fuel is imported. Corn-based renewable fuel ethanol is produced in 19 states, providing jobs and contributing to national energy security. Corn can do more!

Corn Ethanol 2005 Cellulosic Ethanol lagging Total Ethanol Projected Ethanol Usage as Automotive Fuel Benefits from corn and cellulosic ethanol: u Renewable, reduction in oil imports u Oxygenate/Octane enhancer (MTBE replacement) u Agricultural residues (corn stover, wheat straw, rice straw) u New manufacturing -- jobs and rural economic development (Modified from DOE, 2002) Predicted Corn Ethanol
LATEST STUDY: ETHANOL HAS POSITIVE, GROWING ENERGY BALANCE The U.S. Department of Agriculture released a new study of the energy efficiency of ethanol which concludes ethanol production yields 34% more energy than is used in growing, harvesting and distilling grain into ethanol – an increase of 10% over its 1995 energy balance study. The report can be accessed on USDA's web site at: www.usda.gov/oce/oepnu/aer-813.pdf. www.usda.gov/oce/oepnu/aer-813.pdf Co-utilization of corn stover could double ethanol production per acre, cutting average fossil energy use per gallon by half. (LOI) Stover can be used as a feedstock for ethanol and residues burned as boiler fuel for energy to operate the plant. Current technology can produce 60-80 gal/dry ton cellulosics. www.usda.gov/oce/oepnu/aer-813.pdf
Residues from corn fermentation (15% wt) are loaded for processing into animal feed. Could be used to produce fuel ethanol. At 60-80 gallons per dry ton, 4.5 billion 5.2 billion gal/yr Current corn stover (cobs, stems, and leaves) could be used to produce over 25 billion gallons of ethanol/year.

Composition of Lignocellulosic Biomass Glucose polymer Xylose and other sugars Nature’s plastic glue Primarily pentoses, 5-carbon sugars. Homopolymer of glucose, hexose, a 6-carbon sugar. Black thermoplastic containing lots of energy for burning.
E. coli – The Workhorse of Modern Biotechnology 1. This organism can metabolize all of the sugar components (hexose and pentose) of plant carbohydrates but makes a worthless mixtures of fermentation products. 2. Universally present bacterium in gut of all people and all mammals. 3. Best understood living organism in terms of functions and genes. 4. Currently used in industry -- robust, dependable and predictable. 5. Currently used to make amino acids as nutritional supplements and animal feed ingredients (phenylalanine, tyrosine, lysine, threonine, etc.). 6. Currently used to manufacture Nutrisweet (phenylalanine half of aspartame). 7. Currently used to make insulin and a large variety of medical and veterinary products.

How can we reduce our need for 200 billion gal of gasoline? 1. Increase efficiency – each 1% increase in average vehicle mileage reduces the need for 2 billon gallons of fuel. Increase mileage requirements and encourage US automakers to become more competitive with the rest of the world. 2. Near Term Expansion of Renewable Fuel Ethanol (current US production -- 4.5 billion gal/yr primarily from corn starch) Additional corn to ethanol projected to exceed 6 billion gal/yr (~20% of total corn) + 1.5 billion gal Additional 1 billion gal/yr from grain residues + 1.0 billion gal Additional 30 billion gal/yr could be made from corn (cellulosic corn cobs, stalks, stems, leaves) + 30 billion gal 3. USDA/DOE - Potential for > 1 billion tons ~ 100 billion gal (approximately half of imported petroleum)
March 2005 Draft Report by USDA and DOE A Billion-Ton Feedstock Supply for a Bioenergy and Bioproducts Industry Technical Feasibility of Supplying 1 Billion Dry Tons of Biomass This represents half of our automotive fuel and half of imported petroleum. Together with other alternative fuels and Improvements in efficiency, we should be able to eliminate our dependence on imported oil. We need significant Federal R&D&D Investment to reach US Energy Independence. If we had dedicated 1/2 cent per gallon toward the renewable fuel goal after the first oil crisis, we would not be in our current position today.

Dependence on petroleum remains as the remains as the single most important factor affecting the world distribution of wealth, global conflict, human health, and environmental quality. Reversing this dependence would increase employment, preserve our environment, and facilitate investments to improve the health and living conditions for all. 1989 - Professor Ohta conducting fermentation studies at Univ. Fla.
A 10-yr plan for US independence from imported oil should be a National Goal equivalent to the program that placed man on the moon. A billion dollars/yr could be provided to support renewable fuels and chemicals by assigning ½ cent per gallon of current gasoline tax.
