6 FAQs about [Analysis of energy storage field in cold regions]

How do seasonal thermal storage systems improve intermittency of solar energy?

Seasonal thermal storage systems overcome the drawback on intermittency of solar. Heat pump and solar collectors with low-temperature storage improve the performance. Climate, storage temperature, energy efficiency, and life cycle cost are discussed. A decision support flow chart is presented for selection of system options.

What is seasonal thermal energy storage (STES)?

In the seasonal thermal energy storage (STES) technique, the available solar radiation in summer is harvested by solar thermal collectors and stored in large storage tanks or in the ground to be used during winter. The STES system is one of efficient systems for the heating application in building sector, especially in cold climate zones , .

What are the different types of thermal energy storage systems?

The STES systems are typically categorised in four types; hot-water thermal storage (HWTS), borehole thermal energy storage (BTES), aquifer thermal energy storage (ATES) and water gravel pit storage (WGPS). Among these types, the ATES and BTES are most commonly used due to their cost-effectiveness .

Which thermal energy storage system is best for space heating?

The double U-tube borehole thermal energy storage (BTES) integrated with ground coupled heat pump (GCHP) and evacuated tube solar collector (ETSC) system was found to be most appropriate for space heating in cold climate zones.

Why is a low-temperature STES system more suitable for space heating?

The higher the storage temperature, the heat loss would be greater. Studies suggest, the low-temperature STES system would be more suitable for the cold climate conditions. However, the low grade stored heat cannot be directly used for space heating and a heat pump needs to be coupled to upgrade the temperature of delivered heat.

Do heat pump and solar collectors improve system performance in cold climate zones?

Heat pump and solar collectors with low-temperature storage are the influencing factors to improve the system performance. This paper investigates STES systems integrated with heat pump and solar collectors for heating applications in cold climate zones based on the current available literature.
