Abstract Submission Deadline 30 November 2022
Manuscript Submission Deadline 31 January 2023

Energy storage plays a vital role in tackling the challenges of variable renewable energy generation and waste heat availability, as well as the mismatch between energy supply and demand in time and space. Among the resources available to mankind, 80-90% of energy is in the form of thermal energy, which is considered to be one of the most important aspects of the entire energy transmission, conversion, and storage chain, and as a link between primary and secondary energy sources. Thermal energy storage (TES) will become one of the most promising technologies for energy storage at scale. TES technology based on thermal storage materials can effectively store industrial waste heat, solar thermal energy, geothermal energy, and other energy. As an emerging technology of high energy density and high conversion efficiency, it will play an important role in developing a clean, low-carbon, safe, and efficient energy system.

This Research Topic focuses on key issues of improving the overall thermal storage capacity, charging and discharging efficiency, and safety stability of TES systems. Currently, researchers are keen to explore the internal modification of thermal storage materials and external field applications (e.g., electric, ultrasonic, magnetic, and mechanical vibrations) to improve the heat transfer and thermal storage performance of TES systems. A number of challenges and research gaps still need to be addressed to make TES systems more effective. In particular, the relevant mechanism of thermal storage materials in the application of the systems needs to be revealed, and the synergistically enhancing heat transfer under different effects needs to be analyzed, in order to better optimize the design of thermal storage systems. These studies appear to be crucial for the development of thermal storage technologies and the efficient use of energy.

This Research Topic aims to highlight the latest experimental, numerical, theoretical, and technological developments in latent heat thermal energy storage, sensible heat thermal energy storage, and chemical heat energy storage, with the intent to provide a platform for researchers to exchange the latest advances.

Areas of particular interest to be covered in this Research Topic include:
• TES mechanisms
• TES materials
• TES units
• Heat transfer enhancements in TES
• Performance optimization of TES units or systems
• Innovative TES systems
• Applications of TES
• Solar thermal energy using TES
• Heating and cooling based on TES
• Thermal management based on TES

Original Research and Review articles are encouraged.

Keywords: thermal energy storage, energy storage materials, porous media, phase change heat transfer mechanisms, synergistic enhancement
