Phase Change Material (PCM) thermal energy storage systems have emerged as a promising solution for efficient from low to very high-temperature applications. This paper presents an investigation into the utilization of medium temperature range PCM-based domestic hot water application, focusing on different techniques overcome conductivity PCM. Five shell and tube heat exchangers were fabricated employing transfer enhancement methods including fin, expanded graphite (EG), combination fin EG. The EG circular fins exhibited best performance in terms charging discharging, maintaining uniform distribution throughout system due extensive conductive network provided by fins. When PCM/EG/fin exchanger is fully charged, stored 109% higher than that PCM at same elapsed time. Furthermore, demonstrated faster discharging response compared other (TES) configurations, with over 160% power without any methods. These findings emphasize practical viability integrating PCM/EG composite materials systems, offering viable meeting high demand requirements enhanced observed has significant implications improving efficiency reducing operational costs real-world

For the drawbacks of phase change materials such as poor shape stability and weak solar-thermal conversion ability, a rotunda-shaped carboxymethylcellulose/carbon nanotube aerogel (CA) with three-dimensional network was constructed by freeze casting special mold, then impregnated polyethylene glycol (PEG) in this work. The PEG/CA had an enthalpy 183.21 J/g, thermal conductivity 0.324 W m

Abstract Phase change materials (PCMs) that reversibly release or absorb thermal energy during phase transitions play a significant role in promoting renewable and sustainable development. However, the poor shape stability, low conductivity, inferior conversion efficiency of PCMs hinder their wider applicability are difficult to meet growing demand. As precursor carbon‐based materials, including expanded graphite, graphene oxide, graphene, natural graphite (NG) finds extensive applications bring new potentials PCMs, enabling multiple cutting‐edge applications. Herein, we systematically discuss NG its derivative‐based composite for storage, conduction, conversion. This paper aims offer insights into roles hope provide useful guide design next‐generation with high‐energy‐density, high conductivity efficiency.
