Technologies > Propane Propane, or liquefied petroleum gas (LPG) is a byproduct of natural gas production and also can be refined from petroleum. It comes in liquid form and is compressed slightly and/or cooled (propane is a liquid at –44°F). Stored under pressure inside a tank, propane turns into a colorless, odorless liquid. As pressure is released, the liquid propane vaporizes and turns into gas that is used for combustion. Propane refueling facilities store and dispense the fuel as a liquid. Thus refueling facility costs are relatively low. A growing number of vehicles are factory-built to run on propane, others can be converted using EPA/CARB-certified conversion systems. Vehicles that can be converted include pickup trucks, vans, passenger cars, school buses, work trucks, and others. Like natural gas, propane causes less wear on engines, saving maintenance costs. Furthermore, propane is typically 15-50% cheaper than petroleum fuels. Energy content is slightly less (5-10%) than gasoline by volume. Propane is non-toxic and presents no threat to soil, surface water, or groundwater. Propane is also domestically available and helps the US increase its energy security. Propane is the most widely used of any American fuel historically and because propane vehicle technology is well established, propane fueling stations are widely available.
