Research Interests (but not limited to):
A large number of coal mines in Europe are planning mine closure and a just post-closure transition. GeoSolar aims to repurpose end-of-life coal mines as huge thermal batteries for low-carbon, high-temperature district heating, making use of mine land for solar energy installations and mine workings and goaf for thermal energy storage. This project will develop innovative coupled mine water thermal and solar energy storage systems integrated with local district heat networks. Coupled multiphysics modelling of mine water flow and heat storage dynamics will be performed to evaluate the operability and efficiency of the coupled energy storage system during seasonal mine water thermal energy storage and recovery. The deployment of the proposed system is anticipated to achieve widespread societal benefits and social impact, in terms of green energy production, decarbonisation potential, economic growth, and green job creation. The proposed system is also projected to have a huge potential for efficient uptake at European end-of-life and abandoned coal mines.
