Propane, also known as Liquefied Petroleum Gas (LPG), is a by-product of natural gas processing and crude oil refining. Propane is a clean-burning, high-energy alternative fuel that has been used for decades to power light, medium and heavy-duty vehicles. Propane is the most-used alternative fuel in the world and accounts for about 2% of the energy used in the United States.
Benefits of Propane
Energy security: According to the Alternative Fuels Data Center, as of 2014, more than 99% of the U.S. propane supply was produced in North America.
Safety: Propane tanks are 20 times more puncture resistant than gasoline tanks, and propane has the lowest flammability range of all alternative fuels.
Emissions reduction: When considering the entire life cycle of propane used in converted light-duty vehicles (LDVs), Argonne National Laboratory found that propane reduced GHG emissions by 21% to 24% and petroleum use by 98% to 99%.
Convenience: Propane vehicle technology is well established, and propane fueling stations are widely available.
