Seasonal thermal energy storage (STES) harvests and stores sustainable heat sources, such as solar thermal energy and waste heat, in summer and uses them in winter for heating purposes, facilitating the replacement of fossil fuel-based heat supply and coordinating the seasonal mismatch between heat supply and demand .
Solar heating is one of the effective ways of clean heating in northern China, which can achieve low emission and low energy consumption. However, the energy source of solar heating from the solar radiation, which is restricted by weather, region and season, has strong intermittency and instability.
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.
The solar energy industries association predicted that China would become the largest solar heating market in the world, with a global market share over 70% . Solar heating is one of the effective ways of clean heating in northern China, which can achieve low emission and low energy consumption.
The total heating building area is 10000m 2, and the collecting area of 1000m 2. The pipes were buried in the storage volume in a hexagon shape with a volume of 500000m³, and the annual thermal storage capacity is 15000 GJ . Fig. 12. Solar and copper plant waste heat heating system with STES in Chifeng .
As an important technology for solving the time-discrepancy problem of solar energy utilisation, seasonal/long-term storage is a challenging key technology for space heating and can significantly increase the solar fraction. It widens the use of solar collectors and results in better solar coverage of the space heating demand.

Well-developed sensible heat storage is still dominant in large-scale applications. Latent and chemical storage need further investigations prior to practical use.
However, a significant disadvantage of conventional SAGSHPs which use seasonal heat-storage, is that the heat produced by solar collectors at a higher temperature (e.g. 50 °C or higher) is converted into the heat stored in the ground heat storage (GHS), which has a much lower temperature, e.g. 18 °C or lower (Liu et al., 2016). Thus, thermal energy quality is …
