Compressed Natural Gas

Compressed Natural Gas (CNG) is a substitute for gasoline or diesel fuel. It is considered to be an environmentally "clean" alternative to those fuels. It is made by compressing methane (CH₄) extracted from natural gas. It is stored and distributed in hard containers, usually cylinders. Many bus manufacturers build buses that can use this fuel, including Gillig, New Flyer, and Nova Bus.

Buses using CNG usually have large tanks on the roof of the bus in an enclosure that takes up the majority of the roof area.
