In sensible heat storage, the total energy accumulated is proportional to the mass of accumulation material, the specific heat and its temperature. This direct relationship with the mass makes the systems of accumulation by sensible heat large, especially if the storage material is the work fluid ( Fazilati and Alemrajabi, 2013, Gil et al., 2010 ).

If the solar energy completely turns into soil thermal storage, solar radiation energy in 10 days is equivalent to the heat release from soil in this system. But this assumption is not realistic, because not only solar energy utilization efficiency but also the dissipated heat and possible extreme weather are not considered.

The storage system with direct heat exchange operates with 18–23% larger solar fraction than that with immersed coil heat exchangers. Adding PCM modules in the water tank with 50% volume fraction can yield around 40% potential reduction in the storage volume.
In a concentrating solar power (CSP) system, the sun''s rays are reflected onto a receiver, which creates heat that is used to generate electricity that can be used immediately or stored for later use. This enables CSP systems to be flexible, or dispatchable, options for providing clean, renewable energy. Several sensible thermal energy storage ...
