Sewage treatment plants have been among the biggest municipal energy consumers so far. With a new technology that turns the sewage treatment plant from an electricity consumer into a small power plant, a German team of researchers now wants to reverse the trend. The key component of the plant is a bio-electrochemical fuel cell that can directly produce electric power and hydrogen – without the digestion process used so far. For the innovative concept, in the development of which researchers of Karlsruhe Institute of Technology (KIT) are involved, and that is coordinated by TU Clausthal, the group has now received the German Sustainability Award in the category of research.
