synthetic natural gas (SNG)

Synthetic natural gas (SNG) is a form of artificial gas that is produced by a chemical process. It is typically created from biogenic or renewable sources, such as biomass and organic waste, or from non-renewable sources like coal through the process of gasification. It is intended to be a clean-burning alternative to natural gas, and can be used in the same ways, for example for heating and cooking. SNG has a lower carbon output than natural gas, but it releases more pollutants like NOx and SOx than natural gas.
