Special Issue Information

Dear Colleagues,

We are inviting submissions for this Special Issue titled “Thermal Energy Storage for Efficient Utilization: Materials, Process and Systems”.

Thermal energy storage (TES) is rapidly becoming a crucial technology for a sustainable future, offering unique benefits such as helping to decouple heating and cooling demands from immediate power generation and supply availabilities. TES systems have an enormous potential to make thermal energy equipment more efficient and facilitate large-scale energy substitutions from an economic perspective. Recently, TES technologies have developed to a point where they can significantly impact the commercial, industrial and utility sectors, where energy demands vary daily, weekly and seasonally. Currently, research efforts are focused on developing and deploying new techniques to improve TES materials, control strategies, storage unit design and optimization, system integration and advanced numerical models that could further unlock the full potential of TES and support its subtle integration into current and future societies.

In this Special Issue, we invite submissions exploring cutting-edge research and recent advances in TES, focusing on emerging studies and their impact on modern technologies and applications. Both theoretical and experimental studies are welcome, as well as comprehensive reviews and survey papers. The following keywords offer an indication of the topics invited and are by no means limiting.

In pursuit of widespread adoption of renewable energy and the realization of decarbonization objectives, this study investigates an innovative system known as a wind-solar-hydrogen multi-energy supply (WSH-MES) system. This system seamlessly integrates a wind farm, photovoltaic power station, solar thermal power station, and hydrogen energy network at the power grid level. Central to the study is the introduction of a bi-level collaborative optimization model—an innovative algorithmic framework specifically tailored for complex multi-energy systems. This model co-optimizes both the capacity planning of essential system components and their annual load distribution, adeptly navigating the complexities of optimizing capacity and annual load distribution under uncertain energy sources and load conditions. A layered methodology synergistically combines linear programming with an advanced version of non-dominated sorting genetic algorithm-II. When applied to a real-world case study in Zhangbei, China, this approach identifies an optimal system capacity, leading to annual green power generation of 201.56 GW and a substantial reduction of over 173,703 tons of CO2 emissions. An economic analysis further reveals that each 1% reduction in CO2 emissions corresponds to a modest 1.7% increase in the system’s levelized cost of energy. Moreover, a comprehensive exploration of the impacts of various capacity parameters on the WSH-MES system’s performance is conducted. These insights offer invaluable guidance for the large-scale advancement of efficient renewable energy utilization and the attainment of decarbonization targets. Full article

Simulating complex systems in real time presents both significant advantages and challenges. Hardware-in-the-loop (HIL) simulation has emerged as an interesting technique for addressing these challenges. While HIL has gained attention in the scientific literature, its application in energy studies and power systems remains scattered and challenging to locate. This paper aims to provide an assessment of the penetration of the HIL technique in energy studies and power systems. The analysis of the literature reveals that HIL is predominantly employed in evaluating electrical systems (smart grids, microgrids, wind systems), with limited application in thermal energy systems (energy storage). Notably, the combination of electrical hardware-in-the-loop (EHIL) and thermal hardware-in-the-loop (THIL) techniques has found application in the assessment of vehicle thermal management systems and smart cities and, recently, has also been adopted in building systems. The findings highlight the potential for further exploration and expansion of the HIL technique in diverse energy domains, emphasizing the need for addressing challenges such as hardware–software compatibility, real-time data acquisition, and system complexity.
