Electrochaea is commercializing a grid-scale energy storage solution. Our proprietary power-to-gas (P2G) process converts renewable energy and carbon dioxide into grid-quality renewable methane for storage and distribution. Our pilot plants have injected renewable methane into commercial gas grids in Switzerland and Denmark.Using our process, renewable methane is synthesized from CO2 and H2 by our patented biocatalyst, a selectively evolved microorganism – a methanogenic archaea. Pipeline-grade methane is produced in our scalable and robust methanation system for injection into the gas grid or immediate use. CO2 can be recycled from any source such as anaerobic digestors, landfills, dairies, fermentation facilities or industrial processes. And, renewable H2 can be generated from renewable electricity by electrolysis, or from other wasted sources.
