Verified by Toppr

CNG is made by compressing natural gas (which is mainly composed of methane, CH4 stored at high pressure), 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.
Thus they are stored under high pressure.
