Seasonal thermal storage systems meanwhile are used to meet the long-term, seasonal mismatch of available energy and energy demand. Seasonal thermal energy storage is the storing of thermal energy, including heating or cooling potential, for the future long-term use of heating or cooling a building or for other extended periods of time .
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.
The future research direction of seasonal thermal storage based on supercooled PCM is proposed. Seasonal thermal energy storage (STES) is a highly effective energy-use system that uses thermal storage media to store and utilize thermal energy over cycles, which is crucial for accomplishing low and zero carbon emissions.
At present, there are few seasonal thermal energy storage systems with PCMs as the main storage medium, and those that exist are mostly at the experimental stage, and the PCMs that can be applied are relatively single.
Seasonal thermal energy storage was proposed in the United States in the 1960s, and research projects were carried out in the 1970s. In the late 1970s, Nordic researchers also began studying seasonal solar thermal energy storage systems .
