About Clean Cities

Mission To advance the energy, economic, and environmental security of the United States by supporting local decisions to adopt practices that reduce the use of petroleum in the transportation sector

Goal

Reduce petroleum use by 2.5 billion gallons per year by 2020

• Replacement • Reduction• Elimination

Accomplishments• Displaced nearly 3 billion gallons of petroleum since 1993• Put more than 775,000 alternative fuel vehicles (AFVs) on the road• Installed more than 6,600 alternative fueling stations

About Clean Cities

Ethanol Basics

• Renewable fuel produced from plant materials (biomass)

• Same chemical compound in alcoholic beverages (C2H5OH)

• Comes from starchy feedstocks (corn, sugar cane, sugar beets) and cellulosic feedstocks (yard waste, grasses, poplars)

• Blended at low levels into 80% of gasoline sold in the United States

• Increasingly available as E85, for use in flex fuel vehicles

• High-octane fuel

Clean Cities / 5

Basics: Blends

E10• Contains 10% ethanol, 90% gasoline

• Most common blend in U.S.

• EPA: “Substantially similar” to gasoline in all vehicles

E15• Contains 15% ethanol, 85% gasoline

• EPA: “Substantially similar” to gasoline in MY2001 and newer vehicles

E85• Contains 85% ethanol, 15% gasoline

• Alternative fuel under Energy Policy Act of 1992

• Used in flexible fuel vehicles (FFVs)

• Available in most states

Clean Cities / 6

Basics: Blends

Intermediate Blends• E20, E30, E50, etc.

• Only for FFVs

Blender Pumps• Mix E10 with E85 to

create intermediate blends

• Provide flexibility for future changes in regulations

• Allow for choice, based on prices and performance

Clean Cities / 7

Basics: Production

Ethanol from Starch and Sugar• Ethanol from sugar beets and sugar cane

most common in Brazil

• Corn ethanol most common in U.S.o Dry milling

o Wet milling

Clean Cities / 8

Basics: Production

Cellulosic Ethanol• Uses woody, structural parts of

plants

• Crop residues, small trees, grasses

• Research under way to improve cost and efficiency

Basics: Distribution

Clean Cities / 10

Benefits

Energy Security

• More than half of U.S. petroleum is imported

• Production of one unit of corn ethanol requires 0.78 units of fossil energy

Public Health and Environment

• Corn ethanol reduces GHGs by 19% to 52%

• Cellulosic ethanol reduces GHGs by 75%

• Reduces emissions of NOx, CO, benzene, 1,3-butadiene (higher formaldehyde and acetaldehyde emissions)

Existing Infrastructure

• Only minor modifications required

Clean Cities / 11

Use: 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

Clean Cities / 12

Use: Fueling Options

Existing E85 Stations• Ask about fleet discounts

• Communicate potential E85 demand

Converting Existing Equipment to E85

• Newer equipment, clean and in good condition

• Use a contractor that knows state and local rules

Installing New E85 Equipment • Research local regulations

• Use UL E85 listed equipment

• Hire a professional with E85 experience

• Contact the state energy office, industry associations, Clean Cities
