Metal hydrides (MHs) have been considered as thermal energy storage (TES) materials for concentrated solar thermal applications. In this study, a TES system based on MgH2 was designed, constructed and optimized. The thermal conductivity of the MgH2/TiB2/ENG powder was measured using the transient plane source technique. It was found that the thermal conductivity of a MgH2/TiB2/ENG pellet pressed at 223 MPa for 5 minutes and measured in the ...
This article reviewed the use of phase change materials (PCM) as thermal energy storages (TES) as they can be used to substitute large-scale energy demand and assist both economically and environmentally. The thermophysical properties of different phase change materials were studied to assess their viability for thermal storage systems. One of their most common problems with using PCMs is their poor heat transfer rates. This was seen when the transient ...
This article examined the capacity of phase change materials (PCM) to act as phase change thermal energy storages (TES). The review also investigated the thermophysical properties of high temperature PCMs, which can be used as a reference for the design of high temperature phase change TES systems. The transient plane source (TPS) technique was used, among others, to determine the thermal conductivity of the PCMs. It was noted that there ...
This article aimed to analyze the abilities of self-assembled microcapsules containing calcium carbonate shells and paraffin-based binary cores to act as thermal energy storages. The thermal properties of the microcapsules, such as thermal conductivity and phase change properties, were obtained using the transient plane source (TPS) method and analyzed using an instrument. It was found that the thermal conductivity of the microcapsules was enhanced due to their highly thermally conductive ...
Polymeric composite materials were prepared by one-pot synthesis of chromophoric polymer phase change material in nitrogen-doped porous carbon (NPC). Thermal conductivity was found to increase with increasing NPC wt%, enhancing the heating rate with a shorter phase change period....
