Biological conversion of the surplus of renewable electricity and carbon dioxide (CO ) from biogas plants to biomethane (CH ) could support energy storage and strengthen the power grid. Biological methanation (BM) is linked closely to the activity of biogas-producing Bacteria and methanogenic Archae...
