Welsh Water secures funding for sewage to hydrogen project

The project will see biogas waste from sewage sludge converted into hydrogen fuel to power Welsh Water’s zero-emission vehicles

The not-for-profit water company Welsh Water has secured £60,000 funding from Innovate UK for a project that converts sewage into a zero-emission fuel.

The hydrogen fuel, which will be used to decarbonise the firm’s fleet, will come from biogas waste from sewage sludge.

Sludge is a byproduct of the wastewater treatment process, which can then be used as biogas fuel or for other applications, for example as fertiliser.

The project, which is part of a collaboration with Cardiff Council and technology company Costain, is predicted to help the company save around 9,000 tonnes of carbon dioxide and reduce its carbon footprint by 15%.

Welsh Water Director of Environment Tony Harrington said: “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, something we have targeted for 2050, but want to achieve as soon as possible.

“This sewage to hydrogen fuel project is at the forefront of the innovation we need to pursue to meet these ambitious targets and the funding from Innovate UK will help us on the way to decarbonising our fleet of tankers.”
