EPSRC-funded scientists have developed a process using microbes which removes the need to use electricity to process sewage at treatment plants. The microbes can also be used to produce large quantities of valuable hydrogen gas, a source of clean energy.
The team at Newcastle University and Northumbrian Water Ltd unveiled their research (Fuelling the future) at the British Science Festival. They trialled out a hydrogen Microbial Electrolysis Cell (MEC) on sewage at a waste water treatment works on Tyneside.
The team are now preparing to install the next generation of MEC at a waste water treatment works in County Durham.
