Methanol production from biomass and green hydrogen.

Abstract

In a process for producing methanol, a synthesis gas (25) that has been recovered from biomass (5) is fed to a methanol synthesis apparatus (80). In a main operating mode in which sufficient electrical power is available for electrolytic hydrogen recovery, correspondingly electrolytically recovered hydrogen (45) is fed to the methanol synthesis apparatus (80). In a secondary operating mode in which insufficient electrical power is available for electrolytic production of hydrogen (45), a tail gas (26) that arises from a biogas (15) recovered from a biomass (5) on removal of the synthesis gas (25) is fed to a generator (50) in order thus to provide electrical power for apparatuses (10, 20, 30, 40, 70, 80) involved in the process.
