Combined “Renewable Energy–Thermal Energy Storage (RE–TES)” Systems: A Review

Abstract

Current industrial civilization relies on conventional energy sources and utilizes large and inefficient energy conversion systems. Increasing concerns regarding conventional fuel supplies and their environmental impacts (including greenhouse gas emissions, which contribute to climate change) have promoted the importance of renewable energy (RE) sources for generating electricity and heat. This comprehensive review investigates integrating renewable energy sources (RES) with thermal energy storage (TES) systems, focusing on recent advancements and innovative approaches. Various RES (including solar, wind, geothermal, and ocean energy sources) are integrated with TES technologies such as sensible and latent TES systems. This review highlights the advantages and challenges of integrating RES and TES systems, emphasizing the importance of hybridizing multiple renewable energy sources to compensate for their deficiencies. Valuable outputs from these integrated systems (such as hydrogen production, electric power and freshwater) are discussed. The overall significance of RES–TES hybrid systems in addressing global energy demand and resource challenges is emphasized, demonstrating their potential to substitute fossil-fuel sources. This review provides a thorough understanding of the current state of RES–TES integration and offers insights into future developments in optimizing the utilization of renewable energy sources.

Improving the protection system in the distribution networks integrated with photovoltaic cells by changing the ratio of X/R

“…Another is the high cost associated with extracting and transporting this type of fuel [2], [3]. These reasons have prompted many countries to search for new and more economical renewable energy sources that may not be linked to other specific countries to eliminate the dominance of some fossil fuel-producing countries [4], [5]. The most important sources were focused on are the photovoltaic and wind energies [6], [7].…”

Optimal Operation of Cogeneration Power Plant Integrated with Solar Photovoltaics Using DLS-WMA and ANN

“…Hybrid systems might use a continuous energy source such as geothermal, biomass, or ocean thermal to alleviate this issue [9]. However, hybridization of multienergies is inevitable for future development [10]. Compared to an uncoupled power or heat system, the CHP plant has much greater energy efficiency [11].…”

Ionic liquid mixtures as energy storage materials: a preliminary and comparative study based on thermal storage density

“…Within this zone, a heat transfer fluid (HTF) is stored or housed in a thermal energy storage (TES) system. 11–14…”

“…Within this zone, a heat transfer uid (HTF) is stored or housed in a thermal energy storage (TES) system. [11][12][13][14] Nitrate salts (40% KNO 3 + 60% NaNO 3 ), eutectic mixture of diphenyl (DPO) and biphenyl oxide (Therminol VP-1), and mineral or silicone oil are the most commonly used materials as HTF and TES in CSP solar plants. However, each has aspects that hinder the efficiency of the process.…”
