(See fuel properties.). Also known as liquefied petroleum gas (LPG) or propane autogas, propane is a clean-burning alternative fuel that's been used for decades to power light-, medium-, and heavy-duty propane vehicles. Under this pressure, propane becomes a liquid with an energy density 270 times greater than its gaseous form. Propane is used mostly by homes in rural areas that do not have natural gas service. Most propane systems are sold to add power to the vehicle. For retail fuel prices, see the Alternative Fuel Price Report. Propane is frequently preferred as a fuel for a number of reasons including its efficiency, low cost, ease of transport, low environmental impact, and non-toxicity. Of that, less than 3% is used for transportation. Propane has a higher octane rating than gasoline, so it can be used with higher engine compression ratios and is more resistant to engine knocking. In general, propane is frequently preferred when there is a choice between using it and other energy sources as a result of the many benefits mentioned above. However, it has a lower British thermal unit rating than gasoline, so it takes more fuel by volume to drive the same distance. Propane used in vehicles is specified as HD-5 propane and is a mixture of propane with smaller amounts of other gases. An odorant, ethyl mercaptan, is added for leak detection. Propane gas can easily be stored and transported. It is stored under pressure inside a tank as a colorless, odorless liquid. The average homeowner spends about $57 on propane each month and also cuts down on their electric bill.. We are your full-service propane company that can help you make the best and most economical choice for propane products for your home. The North American standard grade of automotive use propane is rated HD 5. This same trend is seen across most other types of propane appliances and equipment compared to electric devices, and the differences are often significant. Construction-friendly. Propane is also shipped by truck, ship, barge, and railway to many U.S. areas. The U.S. Department of Energy estimates that powering water heaters and clothes dryers with propane instead of electricity can save up to 30% to 50% on annual energy costs. Of course, propane systems aren’t sold purely for fuel economy. Propane has a lower flammability than several other fuel sources including CNG, ethanol, and methanol. Though propane can fuel many appliances in your home, few add functionality and improve ambiance like a propane fireplace. It accounts for about 2% of the energy used in the United States. Propane is a three-carbon alkane gas (C3H8). They also last for up to 20 years while many electric water heaters break down after 10 to 12 years. Propane appliances include ranges, ovens, space heaters, furnaces, water heaters, clothes dryers, and air conditioners. Propane has a high octane rating, making it an excellent choice for spark-ignited internal combustion engines. Interest in propane as an alternative transportation fuel stems from its domestic availability, high-energy density, clean-burning qualities, and relatively low cost. The LPG used as auto fuel and cooking gas in Asia and Australia, also has a very high content of butane. The chemical industry also uses propane as a raw material for making plastics and other compounds. One of the most attractive benefits of propane is the fact that it burns significantly more cleanly than other types of fuels. In commercial construction, propane is used much like natural gas. There’s no argument here. It is stored under pressure inside a tank as a colorless, odorless liquid. Propane is also non-toxic and so it is not harmful to water or soil if there is a tank leak, and it is not biologically active. When it comes to heating your home and running your appliances, propane is one of the most affordable fuel sources out there. It provides fuel for energy-efficient gas space heating, water heating, cooking, fireplaces, and clothes drying, though it can also fuel a variety of other building needs. Propane is stored onboard a vehicle in a tank pressurized to about 150 pounds per square inch—about twice the pressure of an inflated truck tire. As one of the most energy and cost-efficient and cleanest burning sources of fuel currently available, propane gas has been used for decades to power a wide range of different types of vehicles, residential and commercial appliances, fireplaces, water heaters, boilers, and farming equipment. Propane is frequently preferred as a fuel for a number of reasons including its efficiency, low cost, ease of transport, low environmental impact… Most propane systems use approximately one gallon of propane to every four gallons of diesel fuel. According to the Gas Processors Association's HD-5 specification for propane, it must consist of at least 90% propane, no more than 5% propylene, and 5% other gases, primarily butane and butylene. The U.S. Environmental Protection Agency found that propane using vehicles produced 50% fewer toxins and emissions than gasoline vehicles. And recreational vehicles (RV's) usually … Its main uses include home and water heating, cooking and refrigerating food, clothes drying, and powering farm and industrial equipment. HD 5 grade has a maximum of 5 percent butane, but propane sold in Europe has a max allowable amount of butane of 30 percent, meaning it's not the same fuel as HD 5. Because of its low boiling point, it can be transported in pressurized containers with a simple nozzle. Propane is produced as a by-product of natural gas processing and crude oil refining. Propane appliances often last longer than their electric counterparts. This connector allows for one-handed fueling and does not require the use of personal protective equipment such as gloves and face shield (which are required for the older style connector). Propane will add power to help … To find the fuel, see propane fueling station locations. Tankless propane gas powered water heaters are up to 83 to 94% energy efficient and cost up to 60% less to operate per year compared to traditional electric water heaters. (See fuel properties.). This field is for validation purposes and should be left unchanged. For vehicle fueling, the quick-release "Type K15" dispenser connector is required to be installed on all new vehicles beginning January 1, 2020, per National Fire Protection Association Code 58. It is the world's third most common transportation fuel, behind gasoline and diesel, and is considered an alternative fuel under the Energy Policy Act of 1992.
