Production and consumption of electricity often follow different trends: e.g. more solar electricity is produced when the sun shines, but less is needed. To compensate this imbalance, the excess electricity should be stored, i.e. it can be converted into a fuel for later use. Microbes at the deep-sea are able to convert the fuel methane reversibly to CO2 and electricity. When this process takes place in reverse, it can convert excess electricity to methane. However, this process cannot be exploited as the microbes needed for it are not
available, nor their function are yet understood. Our project targets to control this process for energy transformation, to understand the biochemistry related to it, and to create similar process in the laboratory via genetically engineered microbes. Accessing this biochemistry via this research is of great fundamental interest, and simultaneously it enables future methods to convert electricity + CO2 to methane.
