“…17,103,112,122 One important consideration in high-grade TES is how temperature affects the thermophysical properties of the storage material. Alami et al 123 compared the application of three different Moroccan rocks, namely igneous, metamorphic, and sedimentary rocks in highgrade TES systems. They reviewed available correlations of thermophysical properties of storage materials as a function of temperature in the literature.…”

Thermal energy is one of the most widely encountered energy forms in our daily life. To ensure efficient utilization and conversion of this energy, the balance between supply and demand needs to be maintained. For this purpose, thermal energy storage is required. There are various thermal energy storage systems available; one of the most basic is sensible thermal energy storage which includes rock thermal energy storage (RTES). This rock‐based energy storage has recently gained significant attention due to its capability to hold large amounts of thermal energy, relatively simple storage mechanism and low cost of storage medium. Accordingly, numerous studies have been conducted to elucidate the basic flow and heat transfer mechanism and to evaluate the performance of this energy storage. The major technical challenges hindering the wide adoption of this technology are the enormous pressure drop across the storage and nonoptimal heat transfer from the heat transfer fluid to the storage medium and vice versa. These issues will directly and indirectly affect the overall cost (capital, operational, and maintenance costs) of the system. To eliminate this issue and assist further development of this technology, it is crucial to compile and extract important findings from these previous studies, identify the challenge and research gap, and draw guidelines for the upcoming research and development. At the moment, this kind of compilation does not exist. Hence, this paper is prepared with the primary objective to comprehensively review the current technology and development of RTES and to propose a potential way forward based on the pain point identified. Discussion on the nontechnical aspect such as policy and regulations as well as community awareness will also be outlined and discussed.

“…The next process is the alteration of loose sediments, into hard rock, through loading and gluing by mineral compounds in solution, and then called sedimentary rock (Andò, 2020). If the sedimentary rock is subjected to increased pressure and temperature as a result of stockpiling and or involved in the process of mountain formation (El Alami et al, 2022), then the sedimentary rock will undergo changes to adapt to the new environment, and formed malihan rock or metamorphic rock. If this metamorphic rock is still subjected to increased pressure and temperature, it will melt again and turn into magma (Moreira et al, 2023).…”

Rocks such as metamorphic and sedimentary are natural constructions. Rocks in natural construction become elementary materials that form the landscape of the area, including in nature-based tourism objects, Bukit Cinta in Gunung Gajah, Klaten, Central Java. The purpose of this research is to describe the elements of rocks in the place. The study method used is descriptive qualitative method and tends to use analysis. The theoretical basis is used as a basic reference in preparing the study report to match the conditions in the field. In addition, the theoretical basis can also provide an overview of the background of the study as material for discussion. The ability to collect data is an important factor in determining the validation of the study conducted. Data collection in this case is obtained secondarily, namely through documents or literature studies. The results of the study found that there are 3 main supporters for the strong landscape in the tourist ojek of Gunung Gajah love hill. The three are metamorphic rocks observed there are fillic metamorphic relief, marble metamorphic rocks, and quartzite metamorphic rocks; limestone sedimentary rocks. Limestone can be used for building materials, road paving, and house foundations; and Diorte igneous rocks. Diorte igneous rocks can be used as home decoration.

“…Furthermore, rocks are used as a SHS medium at the operational pilot plant Airlight Energy Ait-Baha, also given their low cost [25]. Natural rocks can be a sustainable option to improve energy dispatch in CSP plants located in regions with earth-abundant resources [47]. However, waste materials and byproducts are available as a SHS medium, entailing an environmental and economic benefit [48,49].…”

Thermal energy storage (TES) is the most suitable solution found to improve the concentrating solar power (CSP) plant’s dispatchability. Molten salts used as sensible heat storage (SHS) are the most widespread TES medium. However, novel and promising TES materials can be implemented into CSP plants within different configurations, minimizing the TES costs and increasing the working temperature to improve the thermal performance of the associated power block. The first objective of this review is to provide an overview of the most widespread CSP technologies, TES technologies and TES-CSP configurations within the currently operational facilities. Once this information has been compiled, the second aim is to collect and present the existing European and North American TES-CSP Research and Development (R&D) projects within the last decade (2011–2021). Data related to these projects such as TES-CSP configuration path, TES and CSP technologies applied, storage capacity, power block associated and the levelized cost of electricity (LCOE) of the commercial up-scaling project are presented. In addition, project information such as location, research period, project leader and budget granted are also extracted. A timeline of the R&D projects launched from 2011 is built, showing the technology readiness level (TRL) achieved by the end of the project.
