“…Thermocline heat storage is primarily applied in renewable energy systems, with solar energy applications being the most extensively researched avenues. These include CSP plants, Parabolic Trough Power (PTP) plants [18], domestic hot water applications [82], solar cooking systems [83], solar air heaters [35], and the solar cogeneration of power [24]. THS can also be integrated with various energy storage systems such as adiabatic compressed air energy storage [84], liquid air energy storage [85], and Pumped Thermal Energy Storage (PTES) [86].…”

“…In a subsequent study [32], they established a transient model for the thermal-economic analysis and optimization of the entire system, emphasizing the coupling between various system components. Pradeep and Reddy proposed integrating THS with the solar cogeneration of power and desalination, developing a detailed mathematical model to study the impact of factors such as TESMs, porosity, and tank height on system performance [24]. Additionally, economic and environmental analyses were conducted for this combined system.…”

To achieve sustainable development goals and meet the demand for clean and efficient energy utilization, it is imperative to advance the penetration of renewable energy in various sectors. Energy storage systems can mitigate the intermittent issues of renewable energy and enhance the efficiency and economic viability of existing energy facilities. Among various energy storage technologies, thermocline heat storage (THS) has garnered widespread attention from researchers due to its stability and economic advantages. Currently, there are only a few review articles focusing on THS, and there is a gap in the literature regarding the optimization design of THS systems. Therefore, this paper provides a comprehensive review of the recent research progress in THS, elucidating its principles, thermal storage materials, applications, and optimization designs. The novelty of this work lies in the detailed classification and analysis of various optimization designs for THS, including tank shape, aspect ratio, inlet/outlet configuration, thermal energy storage materials arrangement, operating strategies, and numerical model optimization approaches. The limitations of existing research are also identified, and future perspectives are proposed, aiming to provide recommendations for THS research and contribute to the development and promotion of THS technology.
