Abstract

AbstractCoupling 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.
