Production of methane from electricity and CO2

​The main objective of this effort is to develop a scaled-up bioelectrochemical reactor that converts carbon dioxide (CO2) into methane, a fungible energy product, using a process known as microbial electrosynthesis (MES). Electrons are supplied to methane producing microbes located at the cathode in an electrochemical cell by applying an electric current using off-peak renewable energy sources. The electrons are then used by the microorganisms to reduce carbon dioxide to produce methane. The methane can then be injected into the natural gas pipeline as a novel grid energy storage cycle.
