  • ... is non-toxic, environmentally friendly, and in many ways is a safer fuel to use than gasoline.
  • ... is price competitive without government subsidies.
  • ... promotes efficient management and maximum utilization of existing on-site energy resources.
  • ... infrastructure is already in place to deliver fuel in large quantities.
  • ... has been shown as the alternative fuel of choice for future fleet managers in a survey by the USDOE.
  • ... can improve our nation's air quality, reduce our dependence on imported petroleum, support local industries, and can help save fleets money.

VEHICLE DESCRIPTION

  • Gasoline-powered vehicles may be converted to operate on propane in about a day. Or, propane-ready vehicles may be ordered from some manufacturers. See also Department of Energy information on available vehicles and fueling sites: http://www.ccities.doe.gov/advanced.shtml.
  • Since propane burns cleaner than gasoline, the oil, oil filter, and spark plugs in a propane vehicle last up to three times longer than in a vehicle running on gasoline.
  • Propane vehicles can have as much as double the engine life as gasoline vehicles due to drastically reduced lubricant contamination by fuel and little to no carbon build up in combustion chambers and pistons.

VEHICLE AVAILABILITY

  • Many propane powered vehicles are being made available today, such as the Ford F-250.
  • For a listing of this model year's vehicles, go to: www.afdc.doe.gov/afvehicles.html.
  • In Honolulu, the Gas Company services propane vehicles at 515 Kamakee St.
  • A gasoline-powered vehicle may be converted to propane operation in about a day.
  • There are 3.5 million propane vehicles worldwide.
  • In the U.S., more than 350,000 vehicles are fueled by propane.
  • In Hawaii, about 1,500 on-road and off-road vehicles are powered by propane. Vehicle conversions have been available locally for over 20 years.

FUELING

  • Propane is referred to as Liquefied Petroleum Gas, or LPG. It comes from petroleum refining and natural gas processing. The propane fuel grade used in vehicles, HD-5, is mainly composed of propane and butanes.
  • Propane (normally a gas) is stored on a vehicle in liquid form. But when it enters the engine it becomes a vapor again (this is one reason why it can burn so cleanly).
  • Fueling takes about the same amount of time as with conventional gasoline refueling.
  • "Closed" fueling systems prevent leaking and vapor emissions.
  • Propane is stored at 120-127 psi at 60ºF in specially constructed, steel fuel tanks. Propane fuel tanks are 20 times more puncture resistant than conventional gasoline tanks and can withstand four times the normal operating pressure.

 

 

FUEL AVAILABILITY

  • Propane is widely available, with over 300 refueling sites located across the state on all islands.
  • Show information on refueling available for government fleet vehicles in Hawaii
  • Propane has been used as an alternative transportation fuel for more than 60 years.

EMISSIONS

  • Propane is clean burning and produces virtually no sulfur emissions. It emits 60% lower carbon monoxide and 50% lower reactive hydrocarbons than gasoline.

AND...

  • Propane is the third most widely used motor fuel, ranking behind gasoline and diesel.
  • Propane is also used in thousands of forklifts and other off-road and warehouse applications.
  • Engines run by propane are cleaner and last longer. Because of this, it has become popular as a fuel for fleet vehicles and industrial engines.
  • Propane qualifies as both an "alternative fuel" under the National Energy Policy Act and a "clean fuel" under the National Clean Air Act (as amended, 1990).
  • Propane's octane rating is 104 (compared to "premium" gasolines with octane ratings of 91-92).
