Solar inter-seasonal soil heat storage

Seasonal thermal energy storage (STES), also known as inter-seasonal thermal energy storage, 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 from air conditioning equipment can be gathered in hot months for space heating use when needed, including during winter months.. [pdf]

FAQS about Solar inter-seasonal soil heat storage

What is seasonal thermal energy storage (STES)?

Seasonal thermal energy storage (STES), also known as inter-seasonal thermal energy storage, 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.

How does a solar energy storage system work?

At the beginning of the heat storage period, high-temperature nonfreezing liquid heated by the solar collector passes through the heat exchanger, exchanging heat with low-temperature water drawn from the cascaded PCM energy storage tank. This warmed hot water is then circulated back into the tanks.

How much heat does a solar collector store?

The simulation analyzes heat distribution and temperature changes from the heat storage system to the heating terminal. The results indicate that although the solar collectors operate for 26.3% of the total heat storage and heating period, the cumulative heat stored is 45.4% higher than the total heating load.

Can solar energy be used for cross-seasonal heating in highland areas?

Thus, the solar-driven cascaded phase change heat storage system for cross-seasonal heating holds significant application value in highland areas. The system utilizes solar energy as the primary energy source, which is abundant in the plateau region, effectively reducing reliance on traditional fossil energy sources and mitigating carbon emissions.

Can solar thermal energy be used for cross-seasonal heating?

The increase in the tank temperature at the end of the heating period was beneficial for shortening the duration of the heat storage period for the following year. The feasibility of utilizing solar thermal energy and cascaded phase change heat storage for cross-seasonal heating has been demonstrated in this study.

What are heat storage methods for solar-driven cross-seasonal heating?

Heat storage methods for solar-driven cross-seasonal heating include tank thermal energy storage (TTES), pit thermal energy storage (PTES), borehole thermal energy storage (BTES), and aquifer thermal energy storage (ATES) 14, 15, 16. As heat storage volume increases, hot water preparation costs and heat loss per unit volume decrease.
