Large-scale utilisation of renewable energy requires energy storage

Abstract [en]

Most types of renewable energy are available when the demand is low. So, summer heat is available during the warm season, when heating demand is low, and winter cold is available when the cooling demand is low. Therefore, seasonal storage of thermal energy is important for the large-scale utilization of thermal energy. Large-scale storage systems require large storage volumes. Such systems are therefore often constructed as Underground Thermal Energy Storage (UTES) systems. The UTES includes ATES, BTES and CTES i.e. thermal energy storage in aquifers, boreholes, and caverns. UTES systems have been developed during the last three decades and are now found all over the world. Sweden is one of the leading countries in this technology. This is underlined by the fact that borehole systems cover almost 20% of the Swedish heating demand. During the last decade it has been a UTES development towards larger systems for both heating and cooling. Here, different UTES applications are presented.
