文章概要
District energy is one of the main technologies in transition of existing buildings in cities to be heated and cooled without using fossil fuels. But many heat sources as solar thermal, heat from waste-to-energy plants, geothermal energy and excess heat are available only during summer or constantly during the year. 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. Since the 80ties large scale thermal storages have been developed and tested in the Danish energy system. From 2011 five full scale pit heat water storages and one pilot borehole storage have been built. Design and experiences during construction of the first 3 pit heat storages (Marstal 75,000 m3 , Dronninglund 60,000 m3 , Gram 122,000 m3 ) and the pilot borehole storage (Brædstrup 19,000 m3 soil) are now basis for a new generation of large storages integrated in DH systems.
