What is Compressed Natural Gas?

Compressed natural gas (CNG) is produced by compressing natural gas to less than 1% of its volume at standard atmospheric pressure. To provide adequate driving range, CNG is stored onboard the vehicle in a compressed gaseous state at a pressure of up to 3,600 pounds per square inch.

CNG is used in light-, medium-, and heavy-duty applications. A CNG-powered vehicle gets about the same fuel economy as a conventional gasoline vehicle on a GGE basis. One GGE equals about 5.66 pounds of CNG.

Why is CNG a Clean Air Choice® fuel?

CNG vehicles produce far fewer pollutants, including nitrogen oxide (NOx) and particulate matter, than a comparable gasoline or diesel vehicle. In addition, CNG vehicles can produce less carbon dioxide and other greenhouse gases.

CNG IS SUITABLE FOR HEATING, COOKING, ELECTRIC POWER AND VEHICLE FUEL, PRODUCING LOWER GREENHOUSE GAS EMISSIONS THAN CONVENTIONAL FUELS.

What are other benefits?

  • Secure energy source. Most natural gas resources are domestic
  • Cost. Although prices may vary, natural gas is less expensive than gasoline and diesel fuel
  • Flexibility. Many natural gas vehicle models are available. Also, most homes in the U.S. have access to natural gas
