About this Research Topic
Most research on solar energy harvesting concludes that an effective energy storage technology should be developed to address the intermittency issue of renewable energy sources. Solar thermal energy can become dispatchable if there is an integration of thermal energy storage (TES) systems with present solar power systems. Emerging techniques and advanced materials provide a possibility to enhance the efficiency of TES systems. One efficient method of storing thermal energy is through a storage system with the incorporation of organic/inorganic phase change materials (PCMs). PCMs are capable of absorbing and/or releasing large amounts of thermal energy due to a phase transition, and are applicable to various areas, including energy storage and thermal isolation. Melting temperature and enthalpies related to PCMs are dependent on the specifications of specific materials. To categorize PCMs, chemical composition and structure must be considered as well as their integration with the control system. In solar thermal systems, PCMs act as thermal energy absorbance during the day (charging process) and release the thermal energy overnight (discharging process).
This Research Topic attempts to provide insightful knowledge regarding various types of thermal energy storage technologies integrated with solar thermal systems and their control strategies in order to improve the overall efficiency of the whole system. This collection will pay attention to a broad range of operational temperatures in solar thermal systems including low, medium, and high temperatures such as PVT, parabolic dish, parabolic trough and solar power tower and their performance due to the incorporation with various types of thermal energy storage systems and materials.
Topics of interest include, but are not limited to:
• Thermal storage technologies and materials
• Thermal storage modelling,
• Thermal storage system integration,
• Thermal storage management and control
• Integration in Multi-energy systems.
