The latent thermal power storage system has more characteristics than the sensitive storage system. The heating system is a process of releasing and absorbing heat energy using phase transfer material (PCM) and it provides more efficient energy than sensible heat storage. This also consist of high energy storage and high density. It provides high heat transfer in low volume and thereby enhances heat transfer. This enhances the capacity and efficiency of the EFU while extending the service life. The coil tube is designed for latent thermal energy storage to implement and enhance thermal performance during the loading and unloading process. The offloading time, however, was not affected by the flows. Higher throughput has also been shown to improve the effectiveness of recovery. The direction of flow of the HTF did not affect the total time of loading and recharging but affected the temperature changes of the PCM in the energy storage element. It is intended to predict the ability to store maximum energy as higher energy efficiency during the phase shift process. Parameters such as the mean temperature of the PCM, the growth of the melting front, the energy efficiency, and the number of generations of entropy are studied.

“…The solar plant in this study is made up of parabolic trough collectors that use distilled water also as a heat transfer medium (HTF). The HTF is preheated in the solar concentrator and then utilized to heat the geothermal fluid using its heat energy [28]. As discussed, a portion of saline from a producing well is preheated in excessive solar exchange before being supplied into the ORC system's major manufacturing line.…”

Thermal degradation of geothermal energy occurs even during the duration of geothermal energy facilities. The enormity and efficiency of thermal energy available for electric transformation, as well as plant performance and power production, are both affected by the decrease in geofluid heat. Additionally, due to the generally increased turbine exhaust temperatures, the efficiency of geothermal energy based upon air-cooled organic Rankine cycle devices (ORCs) degrades considerably at hot room temperatures. A newly designed Geothermal-Concentrator Solar Power (GEO-CSP) station is simulated in this work, which allows for greater geothermal power use and enhances the effectiveness of the geothermal ORC system over the power plant’s lifespan. The geothermal fluid entering the ORC’s heating element is heated using the sun’s radiation. The CSP facility is fitted with a thermal energy storing unit that stores excess energy from the sun accessible throughout the day and releases it at nighttime whenever the energy system’s performance is better. When the storage facility is included in the concentrator CSP technology, the incremental yearly energy generation from solar increases by 19 percent, from 5.3 percent to 6.3 percent, similar to the geothermal-only plant. As a result, adding a TES unit to the hybrid unit could be quite beneficial.

“…During the heating period a phase change process takes place. Phase change materials (PCMs) can store large quantities of heat, which can be released during periods when solar irradiation is not available [244]. Traditional PCMs like paraffin, organic esters and n-eicosane have poor thermal conductivities (0.2 to 0.7 Wm -1 K -1 ), which limits their heat transfer efficiency [245].…”

The demand for high-quality freshwater is increasing due to global population growth, intensifying agricultural practices and expanding industrial development. Additionally, many global regions have low levels of rainfall which makes them arid and incapable of supporting large human populations or agriculture. Currently, large quantities of fossil fuels are used to generate the power needed to drive energy intensive desalination processes that deliver high-quality freshwater to many of these regions. However, the use of fossil fuels has led to high greenhouse gas emissions, environmental degradation and global warming. Solar-thermal desalination is a low-cost, sustainable and eco-friendly strategy for producing high-quality freshwater without using energy derived from fossil fuels. However, in spite of recent developments to advance solar-thermal desalination, the most effective strategies for achieving higher performance levels still remains elusive. To tackle this problem, the present article reviews several solar-thermal still configurations, including materials, system design parameters, influencing factors and operational parameters. Moreover, recent material advances in plasmonic nanoparticle-based volumetric systems, nanomaterial enhanced phase change materials and interfacial solar evaporators are discussed. These new material advances can have the potential to significantly improve the conversion of light-to-heat, enhance vapor generation and promote greater water production rates.
