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 .
The primary seasonal thermal energy storage for heating presented in this review is BTES [43, 78]. The underlying principle of the technology is consistent with the previous methods, BTES stores thermal energy utilizing soil and rock as a thermal medium [30, 34, 43, 64, 78].
The efficiency of seasonal thermal energy storage combined with a heat pump is evaluated by the solar fraction and the coefficient of performance (COP) of the heat pump. The heat stored in the seasonal storage tank reduces the difference between evaporation and condensation temperatures.
When using ground source heat pump systems and solar thermal systems for space heating, often a thermal storage with an annual cycle time is required to maximize the energy efficiency and solar fraction of the system. The term solar fraction refers to the percentage of the overall load that is supplied by solar.
Solar thermal energy storage is used in many applications: buildings, concentrating solar power plants and industrial processes. Solar thermal water heaters capable of heating water during the day and storing the heated water for evening use are common. TES improves system performance by smoothing supply and demand and temperature fluctuations.
Although storage capacities are significantly larger, solar thermal systems with seasonal storage systems typically have a capital cost of double that of a similar system with only short-term storage . Seasonal thermal storage is not only used with solar thermal heating systems, but is also commonly paired with heat pumps.
