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.

“…Madadi Avargani et al applied the encapsulated paraffin wax to the solar hot water system, which can deliver up to 1200 L of hot water at the required temperature for more than 8 h. Luo et al compounded acidified sepiolite with paraffin by vacuum impregnation and found that the PCM has reliable energy storage and temperature regulation performance. The thermal application properties of CPCMs involving fatty acids and paraffin wax have also been deeply studied in other literature studies. − However, little research has been done on the application of PCMs for the insulation of interior walls in the hot-summer and cold-winter zones.…”

A new form-stable composite phase change material (CPCM) of capric acid-stearic acid-paraffin wax/expanded graphite (CSPW/EG) was prepared by vacuum adsorption. CSPW has a minimum crystallization temperature of 21.9 °C at the eutectic mass proportion of 74.7:8.3:17 by the step cooling curve method and has a phase change temperature of 25.27 °C and an enthalpy of 126.82 J/g by differential scanning calorimetry (DSC). The mixing proportion of CSPW to EG was determined to be 10:1 based on the enthalpy change and leakage of CPCMs; the enthalpy and phase transition temperature of CSPW/EG were 119.26 J/g and 27.14 °C, respectively. The microstructure, crystal structure, and chemical structure of CSPW/EG were characterized by using scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FT-IR), and X-ray diffraction (XRD). The initial weight loss temperature of CSPW/EG was 159.8 °C, which is far beyond the working temperature. The heat storage-release experiments and 1000 melting−solidification cycles also confirmed that CSPW/EG has excellent heat energy storage and temperature control ability, thermal reliability, and great potential in practical engineering heat storage applications.
