Bio-SNG (Synthetic Natural Gas) and Gasification Technologies (VC2)
Bio-SNG is produced by gasification of cellulosic materials (e.g. forestry residues, energy crops), whereas "biogas" is produced by a biological process - anaerobic digestion of organic materials (e.g. manure, organic waste).
Bio-SNG is typically produced via an initial gasification step followed by gas conditioning, SNG synthesis and gas upgrading. Bio-SNG can be used in a similar way to biomethane (biogas) generated via anaerobic digestion. Syngas may also be converted into liquid advanced biofuels. Syngas may be converted to diesel, ethanol (e.g. Fulcrum Bioenergy) or other fuel molecules (e.g. via Methanol To Gasoline technology).
Biomass Gasification Technology Assessment (US 2012)
In November 2012 an extensive Biomass Gasification Technology Assessment was produced by M. Worley and J. Yale, Harris Group Inc. on behalf of NREL. The goal was to solicit and review the technical and performance data of gasifier systems and develop preliminary capital cost estimates for the core equipment. Specifically, the assessments focused on gasification and tar reforming technologies that are capable of producing a syngas suitable for further treatment and conversion to liquid fuels.
