Most natural gas is extracted from gas wells or produced in conjunction with crude oil. Renewable natural gas can also be produced from decaying organic materials, such as waste from plants, landfills, wastewater, and livestock. As transportation fuel, natural gas is compressed (CNG) or liquefied (LNG). With recent expansion of the U.S. natural gas industry, resulting in attractive pricing, it’s an excellent time to consider using this alternative to gasoline and diesel.
- Emission Reductions- on an energy equivalent basis, use of CNG can reduce CO2 tailpipe emissions by 10% or more versus traditional fossil fuels, and lifecycle CO2 emissions by five percent or more (GREET).
- Reduced Fuel Costs- Assuming an annual mileage of 15,000 and a $1/gallon price difference, a pickup truck could save at least $1,000 in yearly fuel costs by driving on natural gas.
- Increased Safety- CNG is considered safer than gasoline and diesel.
- Energy Security- According to the U.S. Energy Information Agency over 90 percent of natural gas used comes from domestic sources compared to less than 50 percent of petroleum.

What Vehicles are Available?
Natural gas vehicle offerings from original equipment manufacturers have expanded from Honda’s Civic to pickups and vans from Chrysler, Ford, and General Motors. Popular heavy duty applications for CNG include refuse, transit and school buses. LNG is moving into the long haul truck market. Many light and heavy duty vehicles can be up-fitted to operate on CNG by companies that have received certification by the U.S. EPA.
The N.C. Clean Energy Technology Center maintains a list of CNG technology providers that serve the North Carolina market. See the Clean Transportation Technology Industry Guide for more details.
