A novel biological procedure uses microorganisms to store electricity from wind and solar energy
They have existed on Earth for more than three billion years and today are to be used to implement a turnaround in energy policy: methanogenic archaea. With their help surplus electricity from wind and the sun can be stored in the form of methane. This can be done particularly efficiently with a patented archaeal-type strain developed by the start-up Electrochaea. The practicability of "biological methanisation" has already been tested in a first pilot plant, and more tests are planned. With the innovation, the company is taking new paths in power-to-gas technology.
