Clean alternative to gasoline and other fuels


What is Compressed Natural Gas?

Compressed Natural Gas (CNG) is an abundant clean burning alternative to gasoline and other transportation fuel. CNG is a readily available alternative to gasoline made by compressing natural gas to less than 1% of its volume at standard atmosphere pressure. There are approximately 110,000 natural gas vehicles currently operating in the United States and 12,000,000 worldwide.

Why Should You Care About CNG?

Why CNG?

CNG is Clean

CNG vehicles improve air quality through the following dramatic reductions in emissions:

  • Reduces carbon dioxide (CO2) emissions by 20% - 30%
  • Reduces carbon monoxide (CO) emissions by 70% - 90%
  • Reduces nitrogen oxide(NOx) emissions by 75% - 95%
  • Reduction of up to 90% of particle matter (PM) emissions
  • Reduces volatile organic compounds (VOC) by 89%

CNG is Affordable

Compressed Natural Gas (CNG) is an affordable alternative when compared to gasoline or diesel fuel. CNG can reduce fuel costs by more than 50% while delivering the same power and performance. Natural gas prices are independent of imported oil prices and are not affected by refinery limitations or interruptions.

Take control of your fuel costs today. The CNG fuel cost at AOG's station generally changes only twice a year, April 1 and November 1. For fueling location and detailed prices, see the CNG Prices and Location section below.

Other Benefits

Local supplies of natural gas are used when producing compressed natural gas (CNG) which in turn supports local jobs, paying gas royalties to local property owners, stimulating our local economy and reducing the amount of American dollars being sent to foreign countries to buy oil.

When used as an automotive fuel, Compressed Natural Gas (CNG) is stored onboard vehicles in tanks that meet stringent safety requirements. Natural gas fuels are "sealed" which prevents spills or evaporative losses. Even if a leak were to occur in the fuel system, the natural gas would dissipate up into the atmosphere – unlike gasoline, which in the event of a leak or accident, pools on the ground, creating a fire hazard. Natural gas is not toxic or corrosive and will not contaminate ground water.

Conversion to CNG

Qualified system retrofitters can also economically, safely, and reliably convert many vehicles for natural gas operation. Most converted vehicles are Bi-fuel: These vehicles have two separate fueling systems that enable them to run on either natural gas or gasoline. The cost to convert specific vehicles starts at $10,700 in our area. According to the miles driven and cost of gasoline, payback can be realized in two to three years.

Original Equipment Manufacturers Honda, Dodge, General Motors, and Ford, are currently producing vehicles with CNG capability or will be offering them in the future. Contact your local dealership for details. More information is available on the NGV Journal website.

Several local dealers have certified their personnel to install CNG conversion kits. For information on converting your vehicle email your request to John Ware.

CNG Home Refueling

Home Refueling

Home fueling compressors are available which will enable you to fill your CNG fleet or vehicle from a separate natural gas service at your home or business. The cost of a home refueling station averages $5,000. Recently General Electric announced that its research division is working to develop a more cost effective unit. Applicable residential service rates will apply For details on residential CNG rates, please visit our CNG Rates page.

For more information on home refueling compressors, please visit one of the following websites:

CNG Fleet Refueling

Commercial Refueling

There are commercial fueling compressors available which would enable you to fill your compressed natural gas vehicles from a separate natural gas service at your business. Normal commercial service rates would apply. For details on commercial rates, please visit our CNG Rates page.

For information on commercial fueling stations, visit CNG Now or email your request to Eddie Fox.

Financial Incentives

Although the federal government does not currently offer any incentives for drivers or fleets that adopt CNG, many states offer tax credits or other benefits for making the switch.


The Arkansas Energy Office will award rebates through its Clean Fuel Vehicle Rebate Program. Currently no funds are available through this Program.


Oklahoma residents are eligible for state income tax credits/rebates for CNG conversions.
