VESTA Methanation Applications for Small Scale, Multipurpose, Green SNG Production

Abstract

The renewable Green Substitute Natural Gas (SNG) production is one of the most flexible approaches to decarbonise end demand such as residential heating and also transportation systems by using compressed SNG. SNG, produced from Biogas, Power to Gas, and Biomass gasification, is a clean and low carbon alternative to conventional natural gas that can be transported and distributed using the existing grid infrastructure. VESTA catalytic methanation developed by Foster Wheeler since 2009 to produce SNG provides an efficient, robust, and viable system that can be adapted to any source of syngas, including the CO2 rich gases typical of biogas upgrading and Power to Gas applications. Technical and economical assessments were performed and presented in this paper for typical renewable application, including: biomass gasification, biogas upgrading, and Power to Gas.
