In Ogmore, Bridgend County Borough Council has commissioned a survey to ascertain whether water held in the former Caerau colliery in the Llynfi valley could provide a sufficient heat source for a project. If the survey results are positive, there are proposals for a geothermal energy project to generate energy for nearly 1,000 homes across the Llynfi valley. This could provide safe, reliable and cost-effective heat and build a green energy industry in the heart of the south Wales coalfields. This project could provide an effective blueprint for how regions across the UK can improve sovereign energy supply security, improve our national performance towards climate change targets and maintain affordable tariffs for consumers. It cannot be overstated however that such a local project provides the much-needed subsidiary benefit of helping to bring investment back to our coalfield communities which have felt the brunt of deindustrialisation for far too long. Likewise, the Butterknowle fault which lies beneath Auckland Castle, Durham, is a geological feature where coal was mined during It’s truly staggering that, across the UK, one quarter of homes are sited above former mine workings. This provides scope for potentially seven million homes which could use mine water heat instead of gas to heat households in a sustainable manner. Therefore, this solution which at first sight appears to be a very local option, could be of benefit to many communities which had never previously considered it to be an option.
