What Is CNG?
Compressed Natural Gas (CNG) is a readily available alternative to gasoline thats made by compressing natural gas to less than 1% of its volume at standard atmospheric pressure. Consisting mostly of methane, CNG is odorless, colorless and tasteless. Its drawn from domestically drilled gas wells or in conjunction with crude oil production.
As gasoline prices continue to rise, interest in CNG is rising accordingly. Natural gas powers more than ten million vehicles on the road today. And with good reason: CNG costs about 40% less than gasoline, it emits up to 90% less emissions than gasoline,and theres an abundant supply.So its affordable, clean, and abundant.
Emissions reductions may vary by pollutant and make/model of vehicle.

Safety:
When used as an automobile fuel, CNG is stored onboard vehicles in tanks that meet stringent safety requirements.
Natural gas fuel systems are sealed, which prevents spills or evaporative losses. Even if a leak were to occur in a 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 has a high ignition temperature, about 1,200 Fahrenheit, compared with about 600 Fahrenheit for gasoline.
Natural gas is not toxic or corrosive and will not contaminate ground water.

History:
The history of compressed natural gas (CNG) as a transportation fuel dates back to World War II. Natural gas vehicles are a proven technology that have been enhanced and refined over the years into a convenient and extremely safe method of transportation.
