In 2019, Fong et al. proposed a novel seasonal energy storage system that primarily utilizes the phase change capacity of groundwater as a storage medium. The system can utilize relatively stable ground temperatures to create a thermal gradient that allows for heating in winter and cooling in summer.
The concept of seasonal/long-term heat storage presents great opportunities for making the utmost use of solar energy. Stored “excess” heat can compensate for the heat shortage when necessary. Seasonal storage offers the possibility that solar energy can cover all the heating loads without an extra heating system.
Fig. 1. Construction concepts for large or seasonal thermal energy storage systems and their advantages and disadvantages . 2.1.1. Tank thermal energy storage (TTES) A tank thermal energy storage system generally consists of reinforced concrete or stainless-steel tanks as storage containers, with water serving as the heat storage medium.
With the above-mentioned merits, chemical storage has become a widely researched technology for seasonal energy storage. Fig. 15. Energy densities of high energy storage methods (N’Tsoukpoe et al., 2009). Chemical storage can be separated into chemical reaction and thermochemical sorption storage (Bales, 2005).
A tank thermal energy storage system generally consists of reinforced concrete or stainless-steel tanks as storage containers, with water serving as the heat storage medium. For the outside of the tank, extruded polystyrene (XPS) is used as an insulation material, and stainless steel is used for the interior to prevent water vapor from spreading.
They can be further classified into water tank and aquifer storage systems. Water tank/pit storage systems store water in an artificial structure, whereas aquifer storage uses natural water directly from the underground layer. 2.2.1.1. Water tank systems
