Researchers at the University of Warwick’s Warwick Process Technology Group have devised a process that turns wet waste from sewage farms and paper mills into a source of power. University of Warwick researcher Dr Ashok Bhattacharya and his team are part of a Europe wide consortium that have cracked the problem of how to extract very pure levels of hydrogen from wet bio-matter, such as sewage or paper mill waste. This very pure hydrogen can then be used in “fuel cells” to power homes, factories and cars.
