Compressed natural gas

CNG, fuel which can be used in place of gasoline, diesel fuel and propane/LPG

Compressed natural gas (CNG) is fuel gas composed primarily of methane (CH4), compressed to less than 1% of its volume at standard atmospheric pressure. It is stored in high-pressure containers at approximately 20–25 megapascals (2,900–3,600 psi; 200–250 bar), typically in cylindrical or spherical shapes.
