CNG

Natural gas which is a mixage of various of hydrocarbons at the lower layers of earth, specially methan(CH4) and Ethan(C2H6), is a fammable gas.
It occurs as a result of degradation of organic structures millions years ago.
It is primary energy. That means it can be used without processing.
Because of being light, can mix into atmosphere easily.
According to calculations, reserve of natural gas on earth is 155 billions m³.
Amount of consumed natural gas on earth per year is around 2 billions m³.

CNG (Compressed Natural Gas) is the state of natural gas compressed.
CNG is used at vechiles by increasing storage capacity through compressing to 200-220 bar.

Natural gas which is between 1 and 70 bar, is compressed to 200 bar with compressor unit and loaded into cylinders, each of them is almost 15m3. CNG dispenser transfers gas from main storage to vechile's storage with 200 bar pressure.
