Large-scale Thermal Storage for District Heating and Cooling

In smart DHC systems, large-scale thermal energy storages (TES) allow for the integration of high shares of renewable energy sources (RES), with excess heat, with excess electricity from RES, and the optimization of combined heat and power plants (CHP).

The International Energy Agency District Heating and Cooling Technology Collaboration Programme (IEA-DHC) in its strategic research agenda include large-scale TES as central elements of future modern DHC systems. The research completed in the IEA-DHC project ‘Integrated Cost-effective Large-scale Thermal Energy Storage for Smart District Heating and Cooling’ (IEA DHC Annex XII Project 3, Contract No. XII-03) contributes towards the development of data, information and analysis tools to encourage the use of cost-effective large-scale underground thermal energy storage (UTES) in DHC systems.
