CNG, an abbreviation for Compressed Natural Gas, refers to low-pressure natural gas that has been pressurized to a high pressure of 25 MPa using boosting equipment.
CNG fueling stations primarily serve to refuel vehicles powered by natural gas, as well as vehicles equipped with on-board gas storage cylinders. Compressed natural gas is a modern, economical, and safe clean fuel, characterized by excellent combustion properties and extremely low exhaust emission levels. Currently, the vast majority of natural gas-powered vehicles utilized worldwide are Compressed Natural Gas (CNG) vehicles; these are vehicles in which natural gas-composed primarily of methane-is stored in on-board cylinders at a pressure of approximately 20 MPa to serve as automotive fuel.
