Compressed natural gas (CNG) is a form of natural gas that is compressed to a pressure of up to 250 bar (3,600 psi) to store it in a compact form for use as a fuel. It is primarily composed of methane, along with small amounts of other gases such as ethane, propane, and butane. CNG is considered a cleaner alternative to traditional gasoline and diesel fuels, as it produces fewer emissions when burned, including lower levels of carbon monoxide, nitrogen oxides, and particulate matter. It is commonly used as a fuel for vehicles, particularly in buses, trucks, and fleet vehicles, as well as in some residential and industrial applications.
