Electromethanogenesis is a technology for converting carbon dioxide into methane. In the case of direct electromethanogenesis (-300 mV vs. SHE), without abiotically produced hydrogen, no significant methane production could be measured. In the case of indirect electromethanogenesis (-700 mV vs. SHE), with abiotically produced hydrogen, a daily methane production of 61 mmol/(m² d) with a coulombic efficiency of 73 % could be achieved using Methanococcus maripaludis. The simulation of a day-night cycle of a photovoltaic system demonstrated the flexibility of electromethanogenesis, which is essential for future storage technologies.
