Large scale thermal storages make it possible to utilize these sources, replace peak fossil based production and integrate fluctuating electricity from PV and wind. This makes thermal storages a key element in future Smart Energy Systems, with integration of heating, cooling, electricity, gas and transport systems.
Dimensions of pilot and research large-scale TES that have been realized within the last 25 years for solar assisted district heating system range from several 100 m3 up to more than 200,000 m3. 2. Borehole thermal energy storages (BTES) in Brædstrup
The most common application of large-scale solar thermal systems is heat supply to DH networks and local heating networks with residential, commercial and public buildings, which makes up 88% of the total installed and operated capacity. Solar process heat, which is mainly used in the mining, textile and food industry, amounts to 12% .
Large-scale Thermal Energy Storage (LTES) systems are necessary to further decarbonise the DH systems and to enable a more flexible operation. LTES are needed, in order to further reduce the specific costs of the storage technology and to have storage capacities that are better suited to the sizes of larger DH systems.
Different countries have ambitious goals for energy and climate change adaptation and mitigation, aiming for 50 % more efficient energy use and 100 % renewable energy generation. Thermal Energy Storage (TES) is a key enabling technology for a realisation of a carbon neutral energy system.
Because of the unstable and intermittent nature of solar energy availability, a thermal energy storage system is required to integrate with the collectors to store thermal energy and retrieve it whenever it is required.
