CNG is the compressed form of Natural Gas, which is mainly composed of methane [CH4]), which is less than 1% of the volume it occupies at standard atmospheric pressure so that large volume of gas can be stored in CNG cylinder.

Coal gas, gaseous mixture—mainly hydrogen, methane, and carbon monoxide—formed by the destructive distillation (i.e., heating in the absence of air) of bituminous coal and used as a fuel.

LPG is composed hydrocarbons containing three or four carbon atoms. The normal components of LPG thus, are propane (C3H8) and butane (C4H10). Small concentrations of other hydrocarbons may also be present. LPG burns readily in air and has an energy content similar to petrol and twice the heat energy of natural gas.

Water gas is a mixture of carbon monoxide and hydrogen produced from synthesis gas. ... The water-gas shift reaction can be used to oxidise the carbon monoxide while producing additional hydrogen, resulting in water gas.
