This article explores the use of phase change materials (PCMs) derived from waste, in energy storage systems. It emphasizes the potential of these PCMs in addressing concerns related to fossil fuel usage and environmental impact. This article also highlights the aspects of these PCMs including reduced reliance on renewable resources minimized greenhouse gas emissions and waste reduction. The study also discusses approaches such as integrating nanotechnology to enhance thermal conductivity and utilizing machine learning and deep learning techniques for predicting dynamic behavior. The article provides an overall view of research on biodegradable waste-based PCMs and how they can play a promising role in achieving energy-efficient and sustainable thermal storage systems. However, specific conclusions drawn from the presented results are not explicitly outlined, leaving room, for investigation and exploration in this evolving field. Artificial neural network (ANN) predictive models for thermal energy storage devices perform differently. With a 4% adjusted mean absolute error, the Gaussian radial basis function kernel Support Vector Regression (SVR) model captured heat-related charging and discharging issues. The ANN model predicted finned tube heat and heat flux better than the numerical model. SVM models outperformed ANN and ANFIS in some datasets. Material property predictions favored gradient boosting, but Linear Regression and SVR models performed better, emphasizing application- and dataset-specific model selection. These predictive models provide insights into the complex thermal performance of building structures, aiding in the design and operation of energy-efficient systems. Biodegradable waste-based PCMs' sustainability includes carbon footprint, waste reduction, biodegradability, and circular economy alignment. Nanotechnology, machine learning, and deep learning improve thermal conductivity and prediction. Circular economy principles include waste reduction and carbon footprint reduction. Specific results-based conclusions are not stated. Presenting a comprehensive overview of current research highlights biodegradable waste-based PCMs' potential for energy-efficient and sustainable thermal storage systems. 

A comprehensive review of critical analysis of biodegradable waste PCM for thermal energy storage systems using machine learning and deep learning to predict dynamic behavior

The current experimental investigation intends to develop leak-resistant form-stable phase change materials (FSPCM) to promote solar energy storage performance implementing biochar as carrier matrix. Date seed biochar (DB) was produced through pyrolysis in a muffle furnace at 550 °C in inert gas atmosphere. Consequently, these carbonized date seeds was utilized as a precursor to derive chemically activated date seed biochar (ADB). BET (Brunauer-Emmett-Teller) surface area of DB and ADB was measured to be 82 m2/g and 197 m2/g respectively. Raman spectra has been carried out to study the molecular interactions, polymorphy and chemical structure of DB and ADB. Both DB and ADB have been employed as porous framework to enhance the heat transfer rate of the eutectic PCM, PA-PEG6000 which was synthesized from palmitic acid (PA) and polyethylene glycol (PEG6000). The composite ADB/PA-PEG6000 has superior PCM holding capacity analogous to DB/PA-PEG6000 owing to the larger specific surface area. Fourier-transform infrared spectra (FTIR) and X-ray diffractograms authenticated that the integration of ADB/DB and PA-PEG6000 have been executed physically. Surface investigation through FESEM illustrated that the pores of ADB and DB scaffold were thoroughly occupied with PA-PEG6000. The latent heat of melting/melting temperature of DB and ADB based FSPCMs were measured to be 202.43 J.g−1/55.3 °C and 210.51 J.g−1/ 56.4 °C respectively. More importantly, the developed FSPCM possess a good thermal and chemical reliability for tested 500 thermal cycles. These developed materials have potential to be used in various solar water/air heating applications.

The storage and use of thermal energy have gained increasing attention from various countries. Phase change materials (PCMs) are commonly used in thermal energy storage (TES) applications due to their high latent heat. More than a hundred single-component PCMs have been reported, each with a specific phase change temperature. In addition to single-component PCMs, eutectic phase change materials (EPCMs) are also used in TES. EPCMs are homogeneous mixtures of binary, ternary, or multiple-component PCMs that melt at a unique temperature lower than the melting point of any of the constituents. Compared to single-component PCMs, EPCMs demonstrate superior performance in TES applications, with a broader phase change temperature range and improved phase stability. This review provides an overview of over 250 organic/inorganic EPCMs from eutectic theory, material classification, thermophysical properties, preparation and characterization methods, techniques for thermal performance improvement, and applications. The review also concludes with a discussion of future prospects and findings that EPCMs can enhance heat storage density and thermal stability when compared to single-component PCMs. This information serves as a reference for the development of heat storage materials with improved thermal physical properties in the future. Overall, this review provides a comprehensive summary of EPCMs from their fundamentals to applications. 

A review on thermal energy storage with eutectic phase change materials: Fundamentals and applications

Abstract In order to achieve global carbon neutrality in the middle of the 21st century, efficient utilization of fossil fuels is highly desired in diverse energy utilization sectors such as industry, transportation, building as well as life science. In the energy utilization infrastructure, about 75% of the fossil fuel consumption is used to provide and maintain heat, leading to more than 60% waste heat of the input energy discharging to the environment. Types of low-grade waste heat recovery technologies are developed to increase the energy efficiency. However, due to the spatial and temporal mismatch between the need and supply of the thermal energy, much of the waste thermal energy is difficult to be recovered. Thermal energy storage (TES) technologies in the forms of sensible, latent and thermochemical heat storage are developed for relieving the mismatched energy supply and demand. Diverse TES systems are developed in recent years with the superior features of large density, long-term, durable and low-cost. These technologies are vital in efficient utilization of low-grade waste heat and expected for building a low or zero carbon emission society. This paper reviews the thermal storage technologies for low carbon power generation, low carbon transportation, low carbon building as well as low carbon life science, in addition, carbon capture, utilization, and storage are also considered for carbon emission reduction. The conclusion and perspective are raised after discussing the specific technologies. This study is expected to provide a reference for the TES technologies in achieving zero-carbon future.

Roles of thermal energy storage technology for carbon neutrality

Sodium acetate trihydrate (SAT) is commonly employed as phase change material for thermal storage due to its low cost, large phase transition enthalpy and suitable temperature range for domestic heating. However, the supercooling property of SAT makes it distinctive to commonly used phase change materials (e.g. paraffin wax). The supercooling of the SAT could be a “rapier”. In some occasions, the supercooling is unfavorable for rapid heat releasing, while in some circumstances the supercooling facilitates the long-term thermal storage without the requirement on thermal insulation. The supercooling phenomenon of SAT is of great interest and importance without proper explanation. This work analyzes and explains the supercooling phenomenon of SAT during phase change process from the perspectives of experiment and molecular dynamics simulation. The result indicates that the supercooling of the SAT is mainly determined by the strong electrostatic interaction between sodium anions and acetate cations induced ions aggregation in the cooling process. The ions aggregation blocks the water molecules to form a crystal structure and induce supercooling effect. The purpose of this paper is to provide a basis for the future application of SAT for thermal energy storage systems.

Theoretical analyses on a piston-based thermal engine for thermal underwater glider

Capillary-wave propellers (CWPs) based on the phenomenon of electrowetting-on-dielectric (EWOD) have shown great potential for floating-object propulsion, heat-transfer enhancement, and fluid thermophysical property measurement. However, the small amplitude of the EWOD-induced capillary-wave limits the performance of the CWP in practical applications. Herein, a CWP with a concave curvature is proposed to enlarge the capillary-wave amplitude. The formation and propagation of the capillary wave are visualized by using a high-speed camera and a free-surface synthetic schlieren method. The wave amplitude and wave propagation are modeled theoretically. The effects of the concave curvature and the frequency of the electrical signal are investigated, and the results show that the concave curvature increases the wave amplitude, velocity vector, and wave intensity as compared with flat EWOD units. In addition, the results show that 20 Hz electrical signals are favorable for pursuing large wave energy density. The underlying mechanism for increasing the wave energy via concave CWPs is revealed experimentally and explained theoretically. The proposed concave CWP is helpful for increasing the propulsion speed of small-scale floating objects and is promising for improving the performance of CWPs in other applications.
