What is CNG?

CNG or compressed natural gas is a domestically available, economical, clean burning, alternative fuel source for vehicles

Why use it?

Emissions reductions

  • Lower emissions than regular petroleum fuel but the same energy output.
  • Fueling with CNG can reduce exhaust emissions of:
    • Carbon monoxide (CO) by 70 percent
    • Non-methane organic gas (NMOG) by 87 percent
    • Nitrogen oxides (NOx) by 87 percent
  • Carbon dioxide (CO2) by almost 20 percent below those of gasoline vehicles.


CNG is typically 1/3 less than petroleum based fuel.  It is also less volatile than the petroleum market.


CNG can be collected from both onshore and offshore wells. US domestic production has boomed out of shale deposits along the Gulf.

CNG Compatible Vehicles- Natural Gas Vehicles (NGV)

  • 9 million natural gas vehicles worldwide and 120,000 in the U.S.
  • Only one consumer CNG compatible car is on the market, The Honda Civic GX .
  • It is possible to convert a regular vehicle into a CNG compatible vehicle, the cost to convert can range from about $12,500 to $22,500 depending on the vehicle, engine, size of CNG tanks needed, and who does the converting
  • Typical Natural Gas Vehicles (NGV) include;  taxi cabs, over-the-road trucks, street sweepers, ice resurfacers, transit buses, refuse haulers, school buses,  delivery vehicles , airport shuttle,  and forklifts.
