However, EV batteries can ensure high performance, prolonged service life, and safe driving only with proper and effective battery thermal management systems (BTMSs). The focus and major contribution of this study to literature is to reveal the role of phase change material's (PCM's) latent heat to the thermal performance of batteries, differentiating the latent heat from the overall thermal energy storage capacity which includes both sensible and latent heat. For that purpose, the phase stable material approach, which is a material with the identical thermophysical properties as PCM but does not undergo phase transformation, was applied. In the study, aluminum radial fin intensified approaches are utilized to enhance the thermal performance of PCM-based BTMS. Additionally to the reference model adding only PCM, 3 different simulation scenarios were analyzed: i) PCM + 1 fin (Design-I), ii) PCM + 3 fins (Design-II), iii) PCM + 5 fins (Design-III). The study was conducted under 5C discharge conditions by integrating 3 different PCMs (RT31, RT38, and RT42) and the impacts of fin distribution, fin dimensions, and housing diameters on thermal behavior of PCM and maximum temperature of battery were numerically studied. The results revealed that the fins enhanced the low thermal conductivity of the PCM by increasing the heat transfer area and can be further improved depending on the intensification of the fins. The refinement of the fin distribution accelerated heat transfer. Compared to the reference case, the temperature decrease was approximately 23.22 %, 12.64 %, and 11.12 % for RT31, RT38, and RT42 in Design-III, respectively. The increase in fin length led to a temperature reduction of up to 2.23 °C, demonstrating greater effectiveness compared to the increase in fin thickness. Reducing the inner diameter of the housing from 34 mm to 26 mm slightly increased the temperature values, but the influence on the liquid fraction was considerable. At the end of the discharge process, the liquid fraction reached from 36 % to 89 %, 28 % to 76 % and 19 % to 65 % for RT31, RT38, and RT42, respectively. Contribution of latent heat in reducing the temperature was 21.94 % in the reference case, 23.51 % in Design-I, 25.4 % in Design-II, and 33.62 % in Design-III.</div></div>","PeriodicalId":15942,"journal":{"name":"Journal of energy storage","volume":"139 ","pages":"Article 118799"},"PeriodicalIF":8.9,"publicationDate":"2025-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145290070","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Haque,&nbsp;Mithulananthan Nadarajah","doi":"10.1016/j.est.2025.118617","DOIUrl":"10.1016/j.est.2025.118617","url":null,"abstract":"<div><div>This paper proposes a comprehensive framework for an EV aggregator to operate as an energy arbitrage entity, aiming to provide a steady income stream to EV owners while reducing grid stress by maximising the system's Load Factor (LF). The framework integrates spatial EV behaviour analysis, machine learning-based forecasting of electricity demand and prices, and a two-stage optimisation process. The first stage utilises Mixed-Integer Linear Programming (MILP) to optimise charging and discharging schedules, thereby maximising EV owner revenue. The second stage employs Gradient-Based Sequential Quadratic Programming (GD-SQP) to optimise the number of participating EVs for grid benefits. The model is built on real-world data from Queensland, Australia, including EV mobility derived from travel surveys and historical 5-minute resolution data from the National Electricity Market. Forecasting performance indicates that the Fine Tree Algorithm (FTA) is most effective for electricity demand prediction, while the Ensemble Bagged Tree Algorithm (EBTA) performs best for price forecasting. Simulation results on the IEEE 9-bus and 39-bus systems validate the framework's performance. In the 9-bus system, LF improves by up to 6.08 % in the H-EV Over-optimum scenario. In contrast, HW-EV scenarios yield reduced LF due to misalignment between revenue-optimised dispatch and system objectives. In contrast, the 39-bus results show that HW-EV Optimum can achieve up to 6.2 % LF improvement, highlighting the influence of grid topology and spatial flexibility. The framework also achieves up to 6.08 % reduction in transmission loss, with additional benefits including peak load shifting, deferred infrastructure investment, and increased revenue for aggregators. An important finding is that longer EV connection durations, as in HW-EV cases, do not guarantee better grid performance due to a trade-off inherent in the two-stage optimisation. These results confirm that EV participation must be carefully managed to strike a balance between economic and technical objectives. Overall, this study demonstrates that data-driven EV coordination, supported by forecasting and dual optimisation, can unlock substantial benefits for both EV owners and the power grid in future smart energy systems.</div></div>","PeriodicalId":15942,"journal":{"name":"Journal of energy storage","volume":"139 ","pages":"Article 118617"},"PeriodicalIF":8.9,"publicationDate":"2025-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145270845","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While underground hydrogen storage (UHS) in porous media presents a viable solution, the H₂ wettability behavior of rocks under various geological conditions remains poorly understood, particularly regarding surface roughness and solvent-induced wettability alterations upon adsorption. Therefore, the present study investigates the wettability and adsorption effects of various solvents on porous sandstone and carbonate rocks in H₂/brine systems under various pressure (0.1–20 MPa) and temperature (293–343 K) conditions. Experiments are conducted using the tilted plate method to measure the advancing (θ_a) and receding (θ_r) contact angles both before and after exposing the substrates to organic solvents mixed with stearic acid. The results reveal that the wettability of sandstone increases with rising pressure and temperature, thereby enhancing the H₂ wettability under reservoir conditions. By contrast, the wettability of carbonate increases with pressure but decreases with the increase in temperature. Hence, these results highlight the importance of mineralogical composition along with the influence of temperature, pressure, surface roughness, and organic acids on solvent adsorption. Moreover, these findings highlight the critical role of H₂ wettability and rock-fluid interactions for optimizing the fluid flow, capillary trapping, and efficiency of the UHS system.
