Innovative geothermal energy scheme in northeast England given green light

17 May 2021

A renewable energy scheme which will draw geothermal energy from abandoned flooded mines in South Tyneside, northeast England has been given a green light. The scheme will cut annual carbon dioxide emissions by hundreds of tonnes, South Tyneside Council has said.

Work will start immediately on the multi-million-pound Hebburn minewater scheme in South Tyneside, which has been granted planning permission for the initial testing phase. The scheme will draw geothermal energy from abandoned flooded mines in the former Hebburn Colliery then used to heat council-owned buildings, including a residential tower block.

Two wells will be drilled to extract water from the mines before testing is carried out to ensure the scheme remains fully viable. Specialist drilling company Dunelm Geotechnical and Environmental Ltd will construct the wells and carry out associated ground investigation works.

Councillor Tracey Dixon, Leader of South Tyneside Council, said: "Work will start on the testing phase of this project without delay. The minewater scheme is expected to deliver a reduction of 319 tonnes of carbon emissions a year, which will make a significant contribution to our ambition for carbon neutrality by 2030.

"It will also help us upgrade the energy performance of fuel-poor homes as it will be used to heat one of the town's residential tower blocks. It's fantastic that the town's industrial legacy will be used in the future fight against climate change and that the old mines will once again produce energy, albeit in a different form. We have already made great strides in reducing our carbon footprint and we will continue to develop highly innovative solutions to become environmentally sustainable."

The water will be extracted by drilling vertical boreholes to a depth of 300-400m into the flooded coal mines underground. A water source heat pump will extract the heat from the minewater before it is compressed to a much higher temperature. It will then feed into an energy centre located above ground and then be distributed via a new pipe network to buildings in the town centre, providing them with low carbon and sustainable heat.

Electricity generated locally using solar panels and a Combined Heat and Power Unit will be used to help power the system. The drilling works and construction of the wells are likely to take until the autumn to complete.

The scheme, which has secured over £3.9million in funding from the European Regional Development Fund, is being developed in collaboration with the Coal Authority and Durham University.
The council declared a climate emergency in July 2019 and pledged to take all necessary steps to make the council carbon neutral by 2030. Since then, it has developed a climate change strategy with a comprehensive five-year action plan.
