Ethanol Basics

  1. 1. Ethanol Basics Wisconsin Clean Cities
  2. 2. Overview• Basic properties• Blends• Production• Distribution• Benefits• Uses: Vehicles & Fueling Options• Resources Wisconsin Clean Cities 2
  3. 3. Basic Properties of Ethanol• Renewable fuel produced from plant materials (biomass)• Comes from starchy feedstocks (corn, sugar cane, sugar beets) and cellulosic feedstocks (yard waste, grasses, poplars)• High-octane fuel Wisconsin Clean Cities 3
  4. 4. Ethanol Blends• Blended at low levels into 80% of gasoline sold in the United States• E10: Most common blend in U.S.• E15: EPA approved for use in MY2001 and newer vehicles• E85: Alternative fuel under Energy Policy Act of 1992; Used in flexible fuel vehicles (FFVs) Wisconsin Clean Cities 4
  5. 5. Blends Continued• Intermediate Blends (E20, E30, E50, etc.)• Blender Pumps – Mix E10 with E85 for intermediate blends – Provide flexibility for future changes in regulations – Allow for choice, based on prices and performance Wisconsin Clean Cities 5
  6. 6. Ethanol Production• Ethanol from Starch and Sugar• Ethanol from sugar beets and sugar cane most common in Brazil• Corn ethanol most common in U.S. – Dry milling – Wet milling Wisconsin Clean Cities 6
  7. 7. Production Continued• Cellulosic Ethanol• Uses woody, structural parts of plants• Crop residues, small trees, grasses• Research under way to improve cost and efficiency Wisconsin Clean Cities 7
  8. 8. Ethanol Distribution Wisconsin Clean Cities 8
  9. 9. Benefits of Ethanol• Energy Security – 1/2 of U.S. petroleum imported – 1 unit of corn ethanol = 0.78 units of fossil energy• Public Health and Environment – Reduces GHGs by 19% to 52% (corn) and 75% (cellulosic) – Reduces NOx, CO, benzene, and other harmful emissions• Existing Infrastructure – Modifications required Wisconsin Clean Cities 9
  10. 10. Ethanol Uses: Vehicles• Flexible Fuel Vehicles (FFVs)• Qualify as alternative fuel vehicles under the Energy Policy Act of 1992• Operate on gasoline, E85, and lower-level blends• Comparable acceleration, payload, speed• Single fueling system• Lower fuel economy on ethanol Wisconsin Clean Cities 10
  11. 11. Ethanol Uses: Fueling Options• Existing E85 Stations• Converting Existing Equipment to E85• Installing New E85 Equipment Wisconsin Clean Cities 11
  12. 12. Ethanol Resources• Alternative Fuels and Advanced Vehicles Data Center (AFDC)• Clean Cities Wisconsin Clean Cities 12
