“…Benato et al [21] studied and compared the effects of 9 storage materials on the RTE, energy density and storage efficiency of Brayton-based CB, including gravel, magnetite and limestone etc. It has been found by Knobloch et al [122] that for a 1 MWhth packed bed STES, there is a 12% lower heat capacity of rocks during a postoperation inspection compared to the initial state, together with decreased bulk density and considerable rock rearrangement. Latent thermal storage, using the advantage of a phase change, can offer heat transfer at nearly constant temperature, and 5 -14 times higher volumetric storage capacities in comparison to STES [123].…”

“…The subsurface rock formations act as a natural reservoir, effectively storing this thermal energy. As the need for energy arises, particularly during peak demand or when renewable energy sources are not readily available, the stored heat is released from the rocks, providing a reliable and on-demand source of energy [53] [54]. One of the key advantages of Rock Bed Storage is its ability to function as a long-term energy storage system.…”

This article highlights the instrumental role of thermal storage applications in addressing contemporary challenges related to energy efficiency and sustainability. The scope of these applications encompasses a diverse range of innovative solutions dedicated to capturing, storing, and effectively utilizing thermal energy. Notably, thermal storage systems emerge as crucial contributors to curbing energy consumption and mitigating greenhouse gas emissions, especially in critical sectors like heating, cooling, and industrial processes. A key revelation is the ongoing focus on materials such as phase change materials (PCMs) and sensible heat storage mediums. These materials, actively applied in research and practical scenarios, contribute to enhancing thermal storage capacity and efficiency, marking a significant advancement in the field. The exploration of diverse applications spans from leveraging thermal storage for solar energy in residential and commercial buildings to the implementation of district heating systems. Beyond improving energy resilience, these applications play a vital role in reducing peak demand on power grids. An intriguing aspect of the research emphasizes the synergy achieved by integrating thermal storage technologies with renewable energy sources like wind and solar power. This integration holds immense promise for establishing a more sustainable and reliable energy supply. In essence, the findings underscore the transformative potential of thermal storage applications, portraying them as pivotal contributors to steering the transition toward a more sustainable and energy-efficient future.
