Compressed natural gas (CNG) is a fossil fuel used as a viable alternative to gasoline, diesel, or propane. It is colorless, odorless, and tasteless. CNG is made by compressing natural gas (which is mainly composed of methane, CH4), to less than 1 percent of the volume it occupies at standard atmospheric pressure. It is stored and distributed in hard containers at a pressure of 20–25 MPa (2,900–3,600 psi), usually in cylindrical or spherical shapes.
