Recent advances in production technology have dramatically increased our reserves of domestic natural gas, stabilized prices, and increased the cost savings relative to gasoline and diesel. This provides further assurance that using American, abundant, affordable natural gas as a vehicle fuel is good for our economy, our environment and our country – for generations to come. Natural Gas Vehicles (NGVs) are powered by compressed natural gas (CNG) or liquefied natural gas (LNG). Both are cleaner, safer and less expensive than traditional fuels. New developments in engine and vehicle technology, more stringent air quality regulations, and government incentives make this choice increasingly attractive.
Our nation has the most extensive natural gas distribution system of any country in the world, making it feasible to install CNG fueling equipment at existing gas stations supplied from existing natural gas lines. There are more than 1,300 NGV fueling stations available now and the number is growing fast. In addition, convenient home refueling with CNG home refueling appliances is already available with more appliances expected on the market soon.
Natural Gas Vehicles (NGVs) are developed based on the same internal combustion engines as gasoline and diesel vehicles and the performance and fuel economy are comparable with those of equivalent conventional vehicles. There are three types of NGV engine applications:
Natural gas can also be stored on the vehicle in two different forms:
Higher gasoline prices and goals of decreasing U.S. oil dependence have spurred interest in natural gas vehicles (NGVs) for personal use and compressed natural gas as an alternative to conventional fuels. In the light-duty category, there are a growing number of CNG vehicles offered by auto manufacturers. In addition, many late model vehicles have EPA-approved after-market conversion systems available.
Purchasing a pre-owned fleet vehicle is another option, especially in states where natural gas has been used for fleet transportation for several decades. States with the highest natural gas fuel consumption rates are California, New York, Texas, Georgia, Massachusetts and Washington, D.C.
Many states have federal vehicle tax credits as incentives for drivers to purchase or convert a qualifying existing vehicle to a CNG vehicle.
