Natural gas is a clean-burning, safe fuel that can save you money at the pump while benefitting the environment and reducing Nigeria's dependence on petroleum. It is a naturally occurring mixture of gaseous hydrocarbon, non-gaseous non-hydrocarbons and gaseous non-hydrocarbons found in underground reservoir rocks either on its own (non-associated gas) or in association with crude oil (associated gas). Natural gas is today accepted as one of the best sources of energy for the world and for the

Nigeria is ranked as the seventh most natural gas endowed nation in the world and relaxes on number one spot in Africa as she seats on about one hundred and eighty-eight trillion cubic feet of natural gas deposits.Current opportunities to utilize gas in Nigeria include: Gas to reinjection schemes, Gas to power schemes, Gas to petrochemicals (as feedstock), LNG-Liquefied Natural Gas, LPG- Liquefied Petroleum Gas, and CNG- Compressed Natural Gas. The use of CNG as auto fuel in Nigeria presents so much benefits as have been highlighted in this paper with emphasis on the economic advantage. Compressed Natural Gas (CNG) is a product of compressing natural gas to one hundredth the volume it occupies at standard atmospheric pressure.A comprehensive economic analysis to determine the cost savings from driving a car on CNG against PMS considered the case of a motorist who covers an average of 100 km every day in the approximately thirty days that make a month was employed. Results established that running a car on CNG amounts to saving N1 143 daily and N34 284 monthly, the cost of converting the car from PMS - driven to CNG - driven is recovered before the end of the sixth month. From the sixth month to the end of the first year, savings of N211 402 is made. Savings of N411 408 is enjoyed each year after the first year.Running vehicles on CNG will greatly reduce the friction and troubles encountered in importing fuel into the country. This will also cut down largely the hardly available foreign exchange expended in bringing in PMS for fuelling vehicles. To this end, the Nigerian Government should as a matter of national development ensure legal and regulatory framework encompassing both technical and commercial aspects for natural gas utilization in Nigeria. Worthy of note is the aspect of gas gathering, gas transmission and distribution which will further encourage the planting of CNG refuelling stations that will serve the expected large fleet of natural gas vehicles. Currently, Green Gas Limited, a joint venture between Nigeria Gas Company (NGC) a Nigerian National Petroleum Corporation (NNPC) and NIPCO Plc. that has nine operational CNG refuelling stations and others under construction is the only company driving the CNG revolution in the country.
