For some period of a year, solar thermal production exceeds the demand for heating or cooling, while in other periods the production is less than the demand. Seasonal thermal energy storage would be a solution to store heat at the time that is not needed and use is for the time that is required.
However, to make thermal storage for electricity storage competitive, the efficiency loss of energy transformation from electricity to heat and back has to be compensated by the cost advantages of the TES and the PV modules.
5. Conclusions Concentrating solar power (CSP) with thermal energy storage (TES) occupies a small but persistent niche in an idealized highly reliable least-cost electricity system with 100% of generation from variable renewable resources.
Consequently, the role of concentrated solar power (CSP) and thermal energy storage (TES) relative to photovoltaics (PV) and batteries has not been clearly evaluated or established for such highly reliable, 100% renewable systems. Electricity generation by CSP is currently more costly than by PV 1. Introduction
The fluid is stored in two tanks—one at high temperature and the other at low temperature. Fluid from the low-temperature tank flows through the solar collector or receiver, where solar energy heats it to a high temperature, and it then flows to the high-temperature tank for storage.
The cost of thermal energy storage system can be reduced and the system performance can be improved. One of the active direct systems is the two-tank direct storage system, which consists of a hot and a cold storage tank, as shown in Figure 7 (a).
Thermal Energy Storage
8.2.1 Physical Principles. Thermal energy supplied by solar thermal processes can be in principle stored directly as thermal energy and as chemical energy (Steinmann, 2020) The direct storage of heat is possible as sensible and latent heat, while the thermo-chemical storage involves reversible physical or chemical processes based on molecular forces.
