Summary: LiCl is a salt hydrate with high energy storage density, but its hygroscopicity limits its application. In this study, a new macro-porous composite foam filled with LiCl was evaluated for low-temperature heat storage. By adjusting the salt hydrate content and optimizing the formulation, the composite foam achieved good hydration/dehydration performance and energy storage density. Considering factors such as sorption, manufacturing, service, and handling feasibility, this material is considered a potentially effective option for low-temperature thermal energy storage.

Summary: Commercial thermal energy storage (TES) systems require reliable thermal performance throughout their lifetime. In this study, it was found that the thermal stability of PCM composites can be degraded by the formation of large crystals during the freezing cycle. However, the use of CMC can retain thermal contacts by forming small PCM crystal networks, stabilizing the thermal conductivity.

Summary: The length of alkyl chain in silanes affects the hydration process and mechanical properties of cement, with shorter chain resulting in stronger retardation of hydration. Changes in porosity due to silane incorporation may also contribute to the decrease in mechanical properties. Additionally, SEM images reveal the formation of fiber-like needle products on the surface of hydrated cement, which are likely composed of specific types of silanes produced from the reaction between calcium hydroxide and silane.

Summary: In the past decade, there has been a growing interest in studying energy systems for the combined management of power vectors. Most of the published works focus on finding the optimal design and operations of Multi Energy Systems (MES). However, for newcomers to this field, understanding how to achieve the desired optimization details while controlling computational expenses can be challenging and time-consuming. This paper presents a novel approach to analyzing the existing literature on MES, with the aim of guiding practical development of MES optimization. Through the discussion of six case studies, the authors provide a mathematical formulation as a reference for building the model and emphasize the impact of different aspects on the problem nature and solver selection. In addition, the paper also discusses the different approaches used in the literature for incorporating thermal networks and storage in the optimization of multi-energy systems.

Summary: This paper investigates the heat transfer mechanism and factors influencing thermal radiation in the process of supercritical water gasification (SCWG) of coal, and proposes a comprehensive numerical model to simulate the process. Experimental validation results show that thermal radiation accounts for a significant proportion of the total heat exchange in the reactor and a large amount of radiant energy exists in the important spectral range of supercritical water. Enhancing radiative heat transfer can effectively increase the temperature of the reaction medium and the gasification rate.

Summary: Pulsating Heat Pipes (PHP) are passive two-phase heat transfer devices with a simple structure and high heat transfer capabilities. The actual unpredictability of their dynamic behavior during startup and thermal crisis hinders their large-scale application. An experimental apparatus is designed to investigate these phenomena systematically. The results show that increasing the number of evaporator sections and condenser temperature improves the performance of PHP. The condenser temperature also affects the initial liquid phase distribution and startup time.
