Synthetic Natural Gas (SNG) - State-of-the-Art Technology and Application Review

S. Fendt, M. Gaderer & H. Spliethoff
Synthetic natural gas (SNG) can be produced by thermochemical or hydrothermal conversion of carbon containing fuels like biomass or coal with subsequent cleaning, methanation and upgrading. In contrast to fossil natural gas, the biomass­derived SNG (Bio­SNG) has a neutral or even negative CO2 balance due to CO2 capture and storage. Although the SNG production process is not a “new” technology, there is still no commercial break­through of the technology for biomass. So far concepts for...
