Natural gas as a vehicle fuel has many of the same advantages that natural gas enjoys in other areas of energy use. Natural Gas is a DOMESTIC energy source with over 95% of the natural gas we use in the United States coming from North American production. ENVIRONMENTALLY, using natural gas produces less CO2 and pollutants than any other readily available form of energy (electricity for example is efficient at the plug, but produces extreme levels of pollution at the source where coal and other fuels are very inefficiently used to produce most of the electricity we consume in this country). EFFICIENCY, the process of converting natural gas to BTU’s of energy is very straightforward and efficient in a direct use application. These items produce a significant cost advantage for natural gas over other fuels as well. The current equivalent cost of natural gas for the energy in one gallon of gasoline is $1.25. For these reasons, natural gas has become a common source of vehicle fuel in some areas of the world. However, transportation fuels present unique problems that are not present in normal stationary fuel applications. In the United States, the convenience of large on board storage tanks (vehicle range) and the supply infrastructure already in place for gasoline and diesel fuel have greatly limited the use of natural gas in the vehicle fuel market.
The advantages of converting vehicles to natural gas use, or buying factory built dedicated natural gas vehicles are:
