Electrochaea
Electrochaea has developed an industrial-scale solution for the production of grid-quality renewable methane which can replace any use of fossil natural gas. The proprietary power-to-gas process converts renewable energy and biogenic carbon dioxide into grid-quality renewable methane (RNG). This technology, called biomethanation, takes hydrogen produced using renewable power and combines it with carbon dioxide to produce methane, effectively storing the renewable electrical energy in the chemical bonds of the methane. The core of our power-to-gas system is a selectively evolved microorganism – a methanogenic archaea – that excels through unprecedented catalytic ability and industrial robustness. Operating plants have injected renewable methane into commercial gas grids in Switzerland and Denmark.
