“…During the light-off operation, the temperature decreased quickly, stabilising the heat release, and dissipating the photothermal storage capacity of ATR@PCM and ATF@PCM, which first increased quickly before decreasing to a constant state. The thermal and energy storage efficiencies were computed using heat loss, which is minimal at low temperatures, and phase transition enthalpy, which increases storage efficiency when solar energy is absorbed (Peng et al 2022). A summary of findings reported on the recent photothermal conversion of methane is presented in Table 4.…”

The current work investigated emerging fields for generating and consuming hydrogen and synthetic Fischer-Tropsch (FT) fuels, especially from detrimental greenhouse gases, CO2 and CH4. Technologies for syngas generation ranging from partial oxidation, auto-thermal, dry, photothermal, and wet or steam reforming of methane were adequately revised alongside biomass valorisation for hydrogen generation, water-electrolysis, and climate challenges due to methane flaring, production, storage, transportation, challenges, and opportunities in CO2 and CH4 utilisation. Under the same conditions, dry reforming produces more coke than steam reforming. However, combining the two techniques produces syngas with a high H2/CO ratio, which is suitable for producing long-chain hydrocarbons. Although the steam methane reforming (SMR) process has been industrialised, it is well known to consume significant energy. However, coke production via catalytic methane decomposition, the prime hindrance to large-scale implementation of these techniques for hydrogen production, could be addressed by coupling CO with CO2 conversion to alter the H2/CO ratio of syngas, increasing the reaction temperatures in dry reforming, or increasing the steam content fed in steam reforming. Optimised hydrogen production and generation of green fuels from CO2 and CH4 can be achieved by implementing these strategies.

“…[ 13 ] With the contribution of supporting or coating materials, form‐stable PCMs can not only overcome the leakage problems, but also make PCMs have high thermal and electrical conductivities. [ 14 ] Methods for the preparation of form‐stable PCMs include core‐shell encapsulation, [ 15 ] physical absorption [ 16 ] and covalent bonding. [ 17 ] The physical adsorption method is most commonly used in the preparation of form‐stable PCMs because of its simple preparation process and equipment requirements.…”

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.
