Power-to-Gas coupling to biomethane production: a feasibility study

conference paper
This preliminary feasibility study on coupling ߿ݐower-to-gas߿ݠconversion chain to the bio-methane from producer gas shows a promising potential for efficient and cost effective operation. The production capacity of the biomethane plant can be doubled, while cold gas efficiency remains the same as compared to a standalone biomethane plant. The specifications of the natural gas grid can be reached at the condition that the allowed H2 content is not too strict. The study showed that such coupling implies that both methanation and SNG upgrade sections need to be designed to withstand variable operation conditions and part-load. The methanation section would have to deal with a turndown factor of 2 when switching from E-demand to E-excess operating mode while the CO2 removal section must work efficiently in part-load and respond well in shutdown/start-up operations.
