Using microbial processes to convert the CO2 separated from biogas to methane

Select microbes have the potential to convert CO2 to methane in a reaction with hydrogen. Such a process enables the utilization, rather than disposal, of CO2 separated from the biogas during the upgrading process.

The hydrogen for the reaction can be obtained from electrolysis of water. To ensure a low carbon footprint for the electrolysis, renewable electricity (such as solar power) is used for electrolysis.
