SoCalGas, PG&E and Opus 12 Announce Advancements in Technology that Converts Carbon Dioxide to RNG
Southern California Gas Co. (SoCalGas), Pacific Gas and Electric Company (PG&E), and Opus 12 today announced they have demonstrated further advancement of a new electrochemical technology that converts the carbon dioxide content in raw biogas to pipeline-quality renewable natural gas, a critical improvement in the science of upgrading waste emissions to renewable gas. The single-step process is designed to use renewable electricity, and thus also provides a way for long-term storage of excess wind and solar power. The twelve-month research and development effort was funded by SoCalGas and PG&E and builds on the success of an initial feasibility study in 2018.
Raw biogas is produced from the anaerobic breakdown of waste from sources like landfills, sewage, and dairy farms. It contains roughly 60 percent methane (the main component of natural gas), and 40 percent carbon dioxide. While current biogas upgrading technology removes the carbon dioxide from biogas, this new technology captures the carbon dioxide and converts it into additional renewable fuel.
