Electrochaea is a new energy company with an innovative solution for storage of intermittent renewable energy. Electrochaea's proprietary technology converts renewable energy and recycled carbon dioxide into low-carbon intensity, sustainable methane, which is reliable, practical, and a safe replacement for natural gas. The sustainable methane can be stored in the existing gas grid infrastructure for use in days, weeks or months. Sustainable methane is synthesized from carbon dioxide and renewable hydrogen using Electrochaea’s patented biocatalyst, archaea microorganism. This scalable solution allows for the efficient and unlimited storage of energy for future use, reduces greenhouse gas emissions, and accelerates decarbonization of the gas grid.
