Nano additive enhanced salt hydrate phase change materials for thermal energy storage

Abstract

Energy storage plays a vital role in sustainable development. Focus on energy storage using phase change materials (PCMs) are of current research hotspot due to high latent heat value. Nevertheless, poor thermal conductivity, supercooling, phase separation, corrosive nature of salt hydrate is of great concern. Distress related to properties of PCM is resolved using nano additives. Major research focus on the dispersion of nano additive with PCM depends on (a) technique of preparing a novel composite PCM; (b) improvement of their thermophysical characteristic; and (c) advanced application for human comfort without polluting the environment. This article presents a critical review of hybridization techniques of metal, carbon and polymer additives on salt hydrate PCMs. To facilitate researchers, the significant variation on thermophysical properties of salt hydrate with nano additives are vitally compared, analysed and critically reviewed. This review article also includes the advanced application of nano additivesbased salt hydrate PCMs.

RETRACTED: Improving the melting performance in a triple-pipe latent heat storage system using hemispherical and quarter-spherical fins with a staggered arrangement

“…As the PCMs have the inherent capability of high latent heat energy storage density, they also have low thermal conductivity, which reduces the heat transfer capability of either conduction or convection modes while charging and discharging the PCM. Several thermal conductivity enhancement methods have been introduced, such as metallic fins and foams ( Abdulateef et al, 2018 ; Mohammed et al, 2020 ; Mahmoud et al, 2021 ; Hashem Zadeh et al, 2022 ; Mohammed, 2022 ), metallic and carbon-based nanomaterials ( Arshad et al, 2020 ; Arshad et al, 2021b ; Kalidasan et al, 2022 ), heat pipes, and metallic matrices ( Eisapour et al, 2022b ).…”

Recent Progress in Polyethylene‐enhanced Organic Phase Change Composite Materials for Energy Management

“…The high thermal conductivity of metals facilitates efficient heat transfer, leading to improved thermal energy storage and release capabilities of the PCM. Ceramic fillers : Metal oxides and ceramic nanoparticles can be added to PE‐PCM to enhance its thermal conductivity and stability [85] . These fillers act as thermal bridges, facilitating the transfer of heat within the PCM and improving its overall heat storage and release properties. Fatty acids and salts : Fatty acids and salts which are called enhancers, can alter the melting and solidification temperatures of the PCM, broaden its phase change temperature range, and further improve its heat storage capacity [86,87] …”

The preparation and selection process for a new form stable phase change material (FSPCM) intended for use as thermal storage in applications at intermediate temperatures

“…A few limitations of O-PCMs consist of their high cost, flammability, and poor heat conductivity. Inorganic PCMs have a higher thermal conductivity than organic PCMs, are non-flammable, have a higher energy storage density, and are less expensive [3]. One of the primary factors determining whether a PCM is suitable for a certain application is its temperature range.…”
