Substitute natural gas (SNG), or synthetic natural gas, is a fuel gas (predominantly methane, CH4) that can be produced from fossil fuels such as lignite coal, oil shale, or from biofuels (when it is named bio-SNG) or using electricity with power-to-gas systems. SNG in the form of liquefied natural gas (LNG) or compressed natural gas (CNG) can be used in road, rail, air and marine transport vehicles as a substitute for costly fuels like diesel and petrol.
