Sewage sludge is being turned into clean energy with the help of latest innovation in fuels cells. These fuel cells will use dry sludge to generate methane gas and reheat it to get high concentration of hydrogen gas to power the cells with water being the by product of the reaction. These fuel cells are cheaper in comparison to fossil fuels and are being used to power green vehicles with successful results. These will cut carbon emissions by 75% and considerably lower vehicular pollution.
