Coupling of biogas upgrading and power-to-X is challenging due to the intermittent cheap energy availability. A system was designed that overcomes the technical challenges in this coupling. This is possible by alternating biogas upgrading and methanol synthesis in a reactor operating both as sorption-enhanced synthesis reactor and as upgrading unit by pressure swing adsorption. It was observed that this concept is feasible in both fixed- and fluidized-bed reactors, and the potential for economic performance improvement was quantified in approximately 20 % increase of the internal rate of return.

Abstract
Coupling of biogas upgrading and power-to-X is challenging due to the intermittent cheap energy availability. A system was designed that overcomes the technical challenges in this coupling. This is possible by alternating biogas upgrading and methanol synthesis in a reactor operating both as sorption-enhanced synthesis reactor and as upgrading unit by pressure swing adsorption. It was observed that this concept is feasible in both fixed- and fluidized-bed reactors, and the potential for economic performance improvement was quantified in approximately 20 % increase of the internal rate of return.File in questo prodotto:
