  1. Alternative Fuel: Ethanol Production from Plant Material By Saujan Sivaram November 17, 2005

  2. Why? • World Consumption of Oil • 75 Million Barrels Daily (2004) • 21 Consumed by US • Decrease Rate of Oil Consumption • Allows for further energy research • Possible quick fix

  3. How Can Ethanol Be Used? • Gasoline Enrichment • Burns Cleaner • E-10 • E-85 • Raises Octane Number • Reduces Spontaneous Combustion (Knocking) • Replaces Methyl Tertiary-Butyl Ether • Source of Hydrogen?

  4. Other Uses?

  5. Agricultural Stats • 9 Billion Bushels of Corn last year • 38% of World Production • 20% Used for Ethanol • 3 billion gallons of ethanol a year

  6. How is it Made?

  7. Actual Steps • Milling • Wet or Dry • Chemical Breakdown (Enzymes) • Heated to 225oF • Starch Breakdown • Fermentation • Only 10% conversion to ethanol

  8. Economics • $4.69 per gallon ethanol • 45 kWh • 1.6 gal ethanol = 1 gal gasoline • Projected to cost $1.07 • $2.05 per gallon gasoline • 35 kWh • 1 Btu fossil fuel = 1.3 Btu output

  9. Advances • Bt Corn! • Insect Repellant • Starch-Water Ratio • Cheap Enzymes • Less Heat Needed • Farm Operation • Milling Techniques

  10. Federal Policy • Clean Air Act of 1990 • Lead Removal • Reformulated Gas • Energy Policy Act of 1992 • Reduce Dependence on Foreign Oil • Mandated Alt. Fuel Vehicles • Renewable Fuels Standard • Use 7.5 bil gal ethanol by 2012

  11. Minnesota State Policy • As of 1997 all gas must be E-10 • Proposed in 2004 that all gas contain E-20 by 2013

  12. Conclusions • 21 Million Barrels Oil Used by US • Ethanol Increases Octane Number • 9 Billion Bushels of Corn last year • 1 Btu fossil fuel = 1.3 Btu output
