It’s domestically produced. It’s environmentally-friendly. It’s the most widely available alternative fuel in the United States. It’s the 3rd most widely used engine fuel in the world. More than 14,600,000 vehicles worldwide use propane as an engine fuel. Now more than ever there are more vehicle choices. Low cost fuel infrastructure and vehicle conversions. Why is propane autogas essential for your fleet?

What is Propane? Propane (C3H8) is sometimes referred to as liquefied petroleum gas, LP-gas, LPG or autogas. Propane is non-toxic and does not contaminate ground water or soil. Propane is a federally designated clean fuel as stated in the Clean Air Act of 1990 and National Policy Act of 1992 and 2005

More than 50% of U.S. propane comes from processing natural gas. >90 % of domestic propane consumption is produced in the U.S. One third of the world supply is produced in Texas.

Propane/Diesel Injection After market system for diesel engines. Injects propane into the diesel. Results: Improved power, reduced diesel consumption, reduced emissions, lower fuel costs.

Vehicle Conversion Costs Dedicated propane alternative fuel vehicles = ~$10,000 pre tax credit. Dual-fuel propane/gasoline AFVs = ~$5,000 - $6,500 (no tax incentive) Propane injection for diesel engines = ~$2,500 (no tax incentive)

Propane Lawn Mowers Propane Lawn Mowers are environmental-friendly alternative to gasoline and diesel mowers. Many of the Propane Lawn Mower models today meet the proposed 2012 EPA air standards emitting significantly fewer hydrocarbons. Reduced opportunity for fuel theft. This allows schools to mow on OZONE ACTION DAYS.

Propane advantages over CNG CNG storage tanks are more than four times larger than a propane storage tank. This reduces valuable space, adds weight. Added weight reduces fuel economy. –CNG 20 gal tank is 600 lbs which is the weight of about 4.5 passengers –A CNG extra range tank adds 280 lbs for only 9 more gallons. Total 29 gal capacity = ~900 additional lbs. Dedicated propane vans have 25 usable gallons without any added weight with a range ~300 miles. The same quantity of CNG will go only 150 miles. CNG storage systems operate at over 17 times the pressure of propane systems (propane = 200 psig vs. CNG = 3,500 psig) CNG high pressure

CNG’s increased weight contributes to: –Premature brake and tire wear –Less load capacity Weight Volume –Reduced plowing capabilities –Reduced towing capacity –Reduced 4x4 capabilities (if any) –Lower fuel economy ratings CNG vehicle tanks requires an inspection every 36,000 miles. Propane tanks have no similar requirement. CNG vehicles have a potential loss of power and torque. Propane vehicles have no noticeable difference in performance. Propane van conversion: $10,000, CNG: $16,500 (pre-tax incentive). Propane advantages over CNG 3 CNG Tanks 2 CNG Tanks CNG Tahoe – rear view

Propane requires a single five to ten horsepower electric motor for refueling, while CNG dispensers require four-stage compressors which typically operate on 460V, 3 phase electric motors. The pump rate for propane is gallons per minute. That is comparable to gasoline pump rates. Slow fill CNG stations may require up to 12 hours to fill a vehicle. CNG stations cost upwards of $900,000 - $1,500,000 to install, while propane refueling stations can cost as little as $20,000… or in some cases propane station are free with a propane fuel contract. Propane stations can be installed within weeks of an order and require a very small physical footprint. Propane is not a greenhouse gas when released directly into the atmosphere. Natural gas (methane) is a greenhouse gas. Propane advantages over CNG
