District Heating
1 The term "District Heat" in this page refers to the "heat" category as defined by the IEA''s Energy Statistics Manual and reported in the IEA''s Energy Balances. This heat is defined as the amount of heat produced and sold. In other words, it is the amount of heat leaving the plant for use by persons unrelated to the producer.

In conjunction with solar district heating systems, five large seasonal heat pit storage solutions were installed [97]. Corresponding to 10 GWh of heat, and with a water volume of 200,000 cubic metres, what is currently the largest heat pit storage solution in the
Seasonal thermal energy storage
Seasonal thermal energy storage ( STES ), also known as inter-seasonal thermal energy storage, [1] is the storage of heat or cold for periods of up to several months. The thermal energy can be collected whenever it is available and be used whenever needed, such as in the opposing season. For example, heat from solar collectors or waste heat ...
Greening the heating supply through the use of thermal solar storage
Seasonal heat storage is a cost-effective way to utilise surplus renewable energy and provides a potential solution to the challenge of matching the demand for energy with a supply of intermittent renewable energy. Utilising PTES for large-scale solar thermal storage in district heating as Denmark does interlinks the heating sector with the ...
Seasonal thermal energy storage with heat pumps and low …
In solar heating systems with seasonal thermal energy storage (STES) the investment cost per square meter of collector area is almost twice that of the system with short term storage [10]. In addition, in short term storage usually the temperature is high, i.e. maximum 95 °C which allows a direct usage in heating distribution network [11] .
