Thermal energy storage (TES) assisted with phase change materials (PCM)s seeks greater attention to bridge the gap between demand and supply. PCM has its footprint toward efficient of solar energy. Inorganic salt hydrate PCMs are propitious over organic in terms ability, thermal conductivity, fireproof, however major issue supercooling poor optical absorbance remains. This research investigates commercialized inorganic transition temperature 50 °C, conductivity 0.593 Wm −1 K which is favoured melting enthalpy 190 J g , 2–3 °C supercooling. Mixture graphene: silver at a proportion (1:1) used as hybrid nanomaterial further enhance absorbance, stability. Hybrid nanocomposites developed via two‐step process involving direct mixing ultrasonication. Morphological behaviour, chemical stability, property, reliability, stability nanocomposite samples experimentally analysed. As result, sustainable TES 0.937 0.8, increased potential formulated. Subsequently numerical simulation conducted illustrate transfer heat

Abstract The current work extensively investigates double‐diffusive of nano‐encapsulated phase change material in a thermal storage system partially filled with porous foam. generation irreversibilities and the influence Soret/Dufour magnetohydrodynamic effects are also considered. circular cold cavity contains corrugated hot cylinder covered by an annular considered parameters Rayleigh number (10 3 –10 5 ), fusion temperature (0.1–0.9), Stefan volume concentration nanoparticles (0–0.05), Darcy −4 −1 ). Hartmann (0–80) undulations inner (3–9). numerical analysis has exploited finite element approximations. results indicate that numbers greatly fluid flow, isotherms, concentrations melting/solidification region. great on region while there is no evident isotherms where both Nusselt Sherwood around 5% number. In contrast, values decreased 30% decreasing Da from 0.1 to 10 . Furthermore, very low heat transfer, mass transfer
