A new project will convert sewage into hydrogen-fuel to power zero-emission vehicles.
The project, which is a collaboration between Welsh Water, a non-profit water company, Cardiff Council and technology company Costain, will see biogas waste from sewage â€˜sludgeâ€™ converted into hydrogen fuel, which will then be used to power zero-emission vehicles.
Sludge is a by-product of the wastewater treatment process, producing microbe-rich solid sewage, which can then be used as a biogas fuel.
The project has so far been awarded Â£60,000 from Innovate UK and it aims to push the production of this green fuel for hydrogen vehicles at one of the companyâ€™s four biogas sites.
Welsh Water is hoping to use this technology to decarbonise its entire fleet of vehicles â€“ saving around 9,000 tonnes of CO2 a year and also significantly reducing their contribution to air pollution.
Tony Harrington, Welsh Water director of environment, said: â€˜These projects are exciting developments to help us become not just a carbon-neutral business but one which produces its own energy using renewable sources â€“ something we have targeted for 2050, but want to achieve as soon as possible.
â€˜This sewage-to-hydrogen fuel project is at the forefront of the innovation we need to pursue to meet these ambitious targets â€“ and the funding from Innovate UK will help us on the way to de-carbonising our fleet of tankers.
â€˜Together with the huge advances in solar, wind and hydropower across our sites, weâ€™re ever closer to reaching our goal of meeting all our energy needs in a sustainable way.â€™
