For solar thermal power generation, the functions of a storage system are to adjust loading, reduce the device capacity and investment cost, further improve solar resources and device use ratio, and improve solar thermal power system reliability and economic performance.
During sunshine hours, the energy collected by the HTF which is passing through the solar collectors can be fed directly to the power block to generate electricity. The excess energy can be supplied to the storage medium with the help of an intermediate heat exchanger.
Solar thermal energy is usually stored in the form of heated water, also termed as sensible heat. The efficiency of solar thermal energy mainly depends upon the efficiency of storage technology due to the: (1) unpredictable characteristics and (2) time dependent properties, of the exposure of solar radiations.
For regions with an abundance of solar energy, solar thermal energy storage technology offers tremendous potential for ensuring energy security, minimizing carbon footprints, and reaching sustainable development goals. Global energy demand soared because of the economy’s recovery from the COVID-19 pandemic.
For applications such as solar stills, thermal energy storage is used for economic reasons. Solar heat storage in a still can be either sensible or latent. A sensible heat storage material stores thermal energy by changing the temperature of the material.
Solar energy storage refers to the thermal energy storage units that can store energy through cooling or heating of a storage medium for cooling, heating, or power generation applications. Solar stills can employ two kinds of energy storage systems.
Storage helps solar contribute to the electricity supply even when the sun isn’t shining. It can also help smooth out variations in how solar energy flows on the grid. These variations are attributable to changes in the amount of sunlight that shines onto photovoltaic (PV) panels or concentrating solar-thermal power (CSP) systems.
