From microorganisms to green methane
How can methane, a gas that is harmful to the climate, become an environmentally friendly energy supplier? Research groups at the Ruhr University Bochum present a promising solution: Using an additional technical module, sewage treatment plants could not only bind CO 2 but also produce methane.
This methane would be compatible with the existing natural gas infrastructure and could cover energy needs - an important step for the energy transition in North Rhine-Westphalia and beyond.
In an additional module that can be adapted to any sewage treatment plant, microorganisms produce methane by metabolizing CO 2 and hydrogen. Research shows that up to 20 liters of methane could be produced per day per inhabitant. Not only would the methane minimize CO 2 emissions, it could also support natural gas supplies.
