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
Eliminate
• 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

Propane Basics
•
Three-carbon alkane gas
C3H8
•
Also known as liquefied
petroleum gas (LPG)
•
Colorless, odorless liquid
(when stored under pressure)
•
High octane rating
•
Nontoxic
•
By-product of natural gas
processing and crude oil
refining
•
Accounts for 2% of energy
used in the U.S.
•
Less than 2% of propane
used in U.S. used in
transportation

Propane Basics
Propane as a Transportation Fuel
• World’s third most common engine fuel
• Considered an alternative fuel under the Energy Policy Act of 1992
• Mix of propane (at least 90%), butane, butylene
• Stored in on-board tank at 125-150 psi
• 25% less energy than gasoline

Propane Basics
Production of Propane
• Domestically produced
• By-product of natural gas
processing and petroleum
refining
• Propane boiling point: -44º F
• Methane boiling point: -127º F
• Separated from methane
through increased pressure,
decreased temperature

Propane Basics
Propane Distribution
• Shipped via pipeline, rail, barge, truck, or tanker ship
• Propane trucks distribute to end users

Propane Benefits
Energy Security
•
•
•
More than 60% of U.S. petroleum
imported
World petroleum supplies in unstable
regions
Propane use diversifies U.S. energy
consumption
Convenience, Performance, Safety
•
•
•
•
•
•
Vehicle technology well established
Fueling stations widely available
Extensive existing infrastructure
High energy density
Low flammability
Puncture-resistant tanks

Propane Benefits
Public Health and Environment
•
Converted vehicles:
o Significant reductions in
particulate matter (PM) and
carbon monoxide (CO)
emissions
o Lifecycle greenhouse gas
emissions reduced 21-24%
•
Manufactured propane vehicles:
o Significantly lower emissions
in PM, CO, Nox, and total
hydrocarbons.
