Southern California Gas Co. (SoCalGas) and Electrochaea today announced the commissioning of the nation’s first scalable biomethanation reactor system at the U.S. Department of Energy’s National Renewable Energy Laboratory (NREL) Energy System Integration Facility in Golden, Colo.  The technology uses renewable electricity to convert hydrogen into pipeline quality methane for use in homes, businesses and in transportation.  Over the next 24 months, the project will assess the commercial viability of this power-to-gas approach to energy storage and decarbonization and provide insights into potential mega-watt scale system designs.
The project in Colorado builds upon and advances research previously conducted by Electrochaea. The reactor system operates at a 50 to 60 percent efficiency.  For every 10 kilowatts-hour of power received by the water electrolysis model, the equivalent of 5 to 6 kilowatts-hour of methane is created by the microbes.
