Nottingham City Council is looking at whether it can add heat from sewage to its existing district heating network.
Research funded by a Department of Energy and Climate Change grant is to be completed by the end of July.
Gail Scholes, Head of Energy Services who is leading the project at Nottingham City Council said: “We are beginning the process by carrying out a detailed assessment of the waste heat potential across the city centre. This will investigate the viability of sewage heat recovery technology.”
Russ Burton, CEO of SHARC Energy Systems which is aiding the research added: “The initial research will cover a site survey, high level heat mapping and energy analysis of large buildings in the designated area, combined with a detailed review of the sewage runs…
“We will also undertake a geological analysis of the city centre area’s bedrock and the suitability of the ground to support a geothermal store and ambient loop distribution system.”
Nottingham’s existing district heating scheme has been working since 1975 and currently heats sites including the Broadmarsh and Victoria shopping centres, Capital One’s UK headquarters and Nottingham Trent University as well as over 5,000 domestic consumers.
