CNG or natural gas is a low environmental impact fuel that reaches the gas stations through the gas pipeline network.
It can also be transported in tanks and tank cars.
In addition to use as fuel for vehicles, it is commonly used in the domestic sector, in the service industry, in manufacturing and for the production of electricity.
CNG is a simple hydrocarbon (alkene) formed by an atom of carbon and 4 of hydrogen; its chemical formula is CH4, and it is found in nature in gaseous form.
It is an excellent fuel because it has high heating power.
In addition to extraction, it is obtained through a process of purification called upgrading of the biogas: In Italy, the legislation has been put in place to permit the use of biomethane without making alterations to the motors.
The CNG sold by Gas Auto Sud is sold with the trademark of a green G.
