Substitute natural gas (SNG), or synthetic natural gas, is a fuel gas (predominantly methane, CH 4) 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.

Synthetic natural gas (SNG) is one of the commodities that can be produced from coal-derived syngas through the methanation process.

Synthetic natural gas (SNG) describes a variety of natural gas alternatives that are as close as possible in composition and properties to natural gas. SNG can be derived from coal, (waste) biomass or synthesized using renewable energy.

The Great Plains Synfuels Plant (GPSP) in Beulah, North Dakota has been in operation producing synthetic natural gas (SNG) from lignite coal for 25 years and remains the only coal-to-SNG facility in the United States.

The Dakota Gasification Company's (DGC) Great Plains Synfuels Plant (GPSP) located near Beulah, North Dakota, is the only coal-to-synthetic natural gas (SNG) gasification plant in operation worldwide, producing approximately 153 MM scf/day of SNG [56 billion scf/year] from 6 million tons/year of lignite.

The key aspects of the plant include (i) carbon dioxide clean-up, (ii) three methanation reactor stages, (iii) heat recovery between reactor stages with ORC units and water condensing and purge...

2020年11月26日 · Via water electrolysis, power surplus on the electric grid is converted into hydrogen or into synthetic natural gas (SNG) that can be directly injected in the natural gas network for long-term energy storage.

=> SNG is the best route for the large-scale production of renewable heat large-scale centralized production plants, transport via gas grid, local consumption, clean conversion

The Power-to-X plant in Werlte provides superior SNG quality, which can be used for multiple purposes, such as the ElbBlue container vessel being the first ship in the world to run on synthetic fuel produced at the Werlte plant.
