“…Based on this fundamental knowledge, FA could theoretically be employed as a supporting matrix to prevent the leakage of fatty acids. Furthermore, the initial feasibility of FA has been confirmed by some scholars to reduce the costs of supporting materials and improve the comprehensive utilization level of FA in the past few years [33][34][35][36][37][38][39][40][41][42]. On the one hand, previous research showed that FA can be employed as a support material to pack LA to fabricate FSPCMs, according to the above-mentioned literature.…”

Fly ash is a kind of industrial solid waste that is considered “hazardous waste”. In this study, a supporting matrix of modified fly ash (MFA) was employed to package lauric acid (LA) via a facile direct impregnation method involving less experimental error. A low-cost and eco-friendly form-stable phase change material (PCM) of LA/MFA/graphene (G) was fabricated, with G as the thermal conductivity enhancer. The preparation and leakage testing of an LA/MFA/G form-stable PCM (FSPCM) were investigated in detail. The leakage test results indicated that good package efficiency was obtained using MFA with a higher specific surface area and richer pore structure to pack the LA. Then, LA/MFA/G composites were characterized via scanning electronic microscope (SEM), Fourier transform infrared spectroscope (FTIR), differential scanning calorimeter (DSC), and thermal gravimetric analyzer (TGA). The results showed that excellent form stability was obtained by adding MFA as the supporting matrix. The SEM analysis indicated that LA could be well dispersed into the structure of MFA. The FTIR analysis demonstrated that the components of the FSPCM were quite compatible. The results of the DSC illustrated that LA/MFA/G (5 wt. %) had a melting point of 45.38 °C and a latent heat of 41.08 J/g. The TGA analysis revealed that the prepared FSPCM had better thermal stability compared with LA within its working temperature range. In addition, the effects of G on the heat transfer performance of the prepared FSPCM were examined. In short, using MFA with a higher specific surface area and richer pore structure to pack the LA via a simple preparation process with less experimental error can contribute to good performance. The research not only improved the comprehensive utilization of solid waste, but also promotes the application of FSPCM in the field of building energy conservation.

“…In spite of this, all the form-stable PCMs exhibited a higher thermal conductivity than that of pure paraffin. The use of recyclable skeletons such as biomass cellulose nanocrystals, [89] fly ash, [92] kapok fiber, [91] and wood fiber [90] had also improved the thermal conductivity of the formstable PCMs by more than 5% compared to the pure organic PCMs. Huang et al [89] prepared form-stable F I G U R E 9 (a) Schematic diagram of heat transfer between form-stable PCMs particles.…”

With the expansion of the global population, the energy shortage is becoming increasingly acute. Phase change materials (PCMs) are considered green and efficient mediums for thermal energy storage, but the leakage problem caused by volume instability during phase change limits their application. Encapsulating PCMs with supporting materials can effectively avoid leakage, but most supporting materials are expensive and consume huge of natural resources. Carbon materials, which are rich and renewable resources, can be used as economical and environmentally friendly supporting skeletons to prepare form‐stable PCMs. Although many researchers have begun to use recyclable materials especially various derivatives of carbon as supporting skeletons to prepare form‐stable PCMs, the preparation methods, thermophysical properties and applications of form‐stable PCMs with recyclable skeletons have rarely been systematically summarized yet. Form‐stable PCMs with a recyclable skeleton can be used as green and efficient thermal storage materials due to their high heat storage capacity and good thermophysical stability after 2000 thermal cycles. This review investigates the effects of recyclable skeletons on the thermophysical properties including phase change temperature, latent heat, thermal conductivity, supercooling, and thermal cycling reliability. Four major kinds of recyclable skeletons are focused on: biomass, biochar, industrial by‐products as well as waste incineration ash. Additionally, the application scales of form‐stable PCMs with recyclable skeletons are explicated in depth. Moreover, the main challenges confronted by form‐stable PCMs with recyclable skeletons are discussed, and future research trends are proposed. This article provides a systematic review of the form‐stable PCMs with recyclable skeletons, giving significant guidance for further reducing carbon emissions and promoting the development of sustainable energy.

“…In recent years, a large number of research papers have proposed a composite phase change TES technology that uses skeleton materials (SMs) to encapsulate phase change materials (PCMs); the PCMs are wrapped in the pores of the SMs to avoid leakage. Al 2 O 3 [36,37], MgO [38,39], Ca(OH) 2 [40], expanded graphite [41,42], expanded vermiculite [43,44], tailings [45,46], SiC [47,48], semi-coke ash [49,50], fly ash [51][52][53], and kaolinite [54,55] are all used as SMs to prepare energy storage composites (ESCs) for TES. SS and RM can also be used as SMs after pretreatment and combined with PCMs to prepare ESCs.…”

Sewage sludge and red mud, as common industrial waste, have become a research hotspot in the field of achieving carbon peaking and carbon neutrality, reducing carbon emissions, and solving environmental problems. However, their treatment and disposal have always been a difficult problem in the environmental field. Utilizing these two materials for thermal energy storage can not only improve energy utilization efficiency but also further reduce carbon emissions during their treatment process, providing a new approach for sustainable development in the industrial sector. This article summarizes the research progress for the resource recovery of sewage sludge and red mud for direct thermal energy recovery and composite phase change energy storage. After proper treatment, sludge and red mud can be directly used as energy storage materials. In addition, sludge and red mud can be combined with phase change materials to prepare composite materials with an excellent energy storage performance. This composite has broad application prospects in fields such as solar energy utilization and building energy efficiency. However, there are still some challenges and issues in this resource recovery and utilization, such as potential environmental pollution during the treatment process, the long-term stability of energy storage materials, and cost-effectiveness, which require further research and resolution. The purpose of this paper is to evaluate the potential of sewage sludge and red mud as energy storage materials, to explore their feasibility and advantages in practical applications, and to reveal the research progress, technical challenges, and future development directions of these two materials in the field of thermal energy storage.
