Compressed Natural Gas (CNG) as a Transportation Fuel. Compressed natural gas, or CNG, is natural gas under pressure which remains clear, odorless, and non-corrosive. Although vehicles can use natural gas as either a liquid or a gas, most vehicles use the gaseous form compressed to pressures above 3,100 pounds per square inch. Most natural gas comes from three types of wells: natural gas-and-condensate wells, oil wells, and coal bed methane wells.
