Liquid systems store solar heat in tanks of water or in the masonry mass of a radiant slab system. In tank type storage systems, heat from the working fluid transfers to a distribution fluid in a heat exchanger exterior to or within the tank. Tanks are pressurized or unpressurized, depending on overall system design.
Natural solar water-based thermal storage systems While water tanks comprise a large portion of solar storage systems, the heat storage can also take place in non-artificial structures. Most of these natural storage containers are located underground. 4.1. Aquifer thermal energy storage system
Active solar heating systems use solar energy to heat a fluid -- either liquid or air -- and then transfer the solar heat directly to the interior space or to a storage system for later use. If the solar system cannot provide adequate space heating, an auxiliary or back-up system provides the additional heat.
The system stores solar energy in a compact volume that can be extracted by heat pumps for later use (Philippen et al., 2018). This stored heat can be used in cold periods until the water freezes. Similarly during summer the cold can be extracted from the ice storage for space cooling until the ice converts back to liquid phase.
2.1. Thermal storage Solar thermal storage (STS) stores accumulated solar energy, which is received by different types of solar collectors, for later use. They are majorly efficient in regard of providing energy to meet the peak energy demand.
For the utilization of solar energy, first it needs to be collected with the help of a solar collector, then it may be directly converted into electricity (through a solar panel), or it may be absorbed by the heat transfer fluid (HTF) flowing through the solar collector system and then transferred to any application.
