Commercial produced biogas contains app. 60% of methane, 35% of CO2 and 5% of steam, nitrogen and further impurities. To feed in the biogas into the existing natural gas grid it has to be cleaned from all impurities at the moment in a cost-intensive way.
In line with the funding initiative “CO2Plus – Stoffliche Nutzung von CO2 zur Verbreiterung der Rohstoffbasis“ from the Federal Ministry of Education and Research the project “MIKE” is going to use microbial electrosynthesis to increase the methane output of an industrial biogas plant and therefore to reduce the cleaning effort.
In microbial electrosynthesis electroactive microorganisms take up electrons from a cathode for the reduction of CO2 to different chemical products, e.g. methane. In contrast to other processes, the microbial electrosynthesis has very high cathodic electron efficiency (> 80%). As electron source current can be used from renewable energies or from excess current.
The main goals of the project are as follows:
Due to the project “MIKE”, not only the methane yield of an industrial biogas plant can be increased, but also excess current can be stored as methane.
