Thermal runaway propagation in battery modules can cause cascading cell failure, equipment damage, production losses, warranty costs, and interruptions in electric-vehicle and grid-scale energy-storage operations. However, the combined effects of cooling-channel geometry, coolant properties, battery reaction kinetics, heat-release behaviour, pumping-energy consumption, and system operating cost remain insufficiently quantified. This study develops and experimentally validates a three-dimensional multiphysics model of a six-cell prismatic lithium iron phosphate battery module integrated with N-profile mini-channel cold plates. The model achieved a root mean square error of 3.82 °C and a mean absolute error of 2.64 °C against thermocouple measurements. Channel widths of 3–12 mm, coolant velocities of 0.01–0.03 m/s, and aqueous glycol concentrations of 20%, 50%, and 80% were evaluated over a 7000 s operating period. Without active cooling, thermal runaway occurred in the three cell rows at 797, 1,211, and 1752 s, respectively. Effective cooling reduced the central-cell heat release from 2296.55 to 409.27 kJ and prevented further propagation. Based on a 200 °C peak-temperature threshold, the system was classified into full-propagation, partial-transition, and complete-suppression regimes. The configuration combining an 8 mm channel width, a coolant velocity of 0.02 m/s, and a 50% glycol mixture provided the most favourable balance between thermal protection and energy consumption. It improved the cooling-efficiency factor by 28% relative to the conventional coefficient-of-performance baseline while maintaining practical pumping-power requirements. These findings demonstrate that excessive coolant flow or glycol concentration does not necessarily provide an economically efficient thermal-management solution. The proposed energy–thermal–economic assessment framework offers a quantitative pathway for reducing safety-related losses, auxiliary electricity consumption, and operating costs while improving the reliability and market competitiveness of lithium-ion battery manufacturing and deployment in China.</div></div>","PeriodicalId":11546,"journal":{"name":"Energy Strategy Reviews","volume":"66 ","pages":"Article 102323"},"PeriodicalIF":12.1,"publicationDate":"2026-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148635044","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Due to the complexity of directly controlling decentralized demand-side technologies, incentive mechanisms present a promising solution for harnessing demand-side flexibility. This study investigates various incentive schemes that encourage grid-supportive demand-side behavior, focusing on heat pumps by developing a bi-level programming framework. The framework models the decision-making processes of key stakeholders, including a TSO, an aggregator, and a market clearing agent, considering model-endogenous wholesale market equilibrium formation and congestion management optimization. The economic efficiency of different design options for grid congestion management is evaluated using an extended IEEE test system adjusted to an exemplary German market configuration.

Thus, the primary objective is to determine long and short-run elasticities among energy and environmental pollution factors. For empirical investigation CS-ARDL method is used and outcomes are revealing a negative relationship between carbon emissions and CRW. In other words, the results endorsed that the integration of CRW into manufacturing and electricity generation could support the economies evolution toward low-carbon development trajectories. These outcomes are crucial for the developing nations where industrial growth and energy demand both are growing swiftly. Thus technological evolution for efficient use of CRW can reduce the carbon intensity of GDP, and may support climate mitigation goals. Moreover, renewable energy poverty is recognized as a contributing factor to amplified carbon emissions, while enhancements in energy justice determine a mitigating effect on emissions. Furthermore, the study highlights that policymakers, governments, and stakeholders should prioritize strategies to assimilate CRW into manufacture sectors, yielding numerous benefits such as cost-effective production, reduced emissions, and advancement toward SDG-11. The study proposed that alleviating energy poverty and cultivating energy security through renewable clean energy channels could be an operative strategy for carbon mitigation, whereas pursuing the same objective through carbon-intensive sources such as fossil fuels likely to exacerbate the environmental challenges.

This study develops and applies an integrated TIMES_NE urban energy modeling framework to examine adaptive planning pathways for Gothenburg, Sweden, over the 2018–2050 planning horizon. The framework combines scenario analysis, system-cost optimization, price sensitivity analysis, and stakeholder-informed uncertainty processing to evaluate interactions among buildings, district heating, transport, electricity, and biomass resources. A central novelty of the study is the explicit representation of cross-sectoral resource competition, particularly the competition for limited biomass resources between district heating and transport biofuels. The results show that building rehabilitation under the City Energy Plan scenario reduces annual district heating demand for existing multi-family housing by 16% by 2050. Transport energy consumption decreases by 57% under the City Energy Plan scenario, compared with 42% in the Reference scenario, mainly due to modal shift, efficiency improvements, and vehicle electrification. Across scenarios, total electricity demand increases by 43–56% above 2018 levels by 2050, with heat pumps accounting for 14.5–19% and electric vehicles for 24–25% of total electricity use. Bio-resource consumption increases from 0.9 TWh in 2018 to as much as 4.8 TWh by 2050 under base bio-resource pricing, creating significant competition between heating and transport. The district heating system shifts toward biomass combined heat and power under low bio-resource costs, but toward central heat pumps under high bio-resource costs. These findings demonstrate that adaptive, cross-sectoral planning is essential for avoiding resource lock-in, managing electrification-driven grid pressure, and aligning short-term municipal energy targets with long-term resilient urban decarbonization pathways.</div></div>","PeriodicalId":11546,"journal":{"name":"Energy Strategy Reviews","volume":"66 ","pages":"Article 102307"},"PeriodicalIF":12.1,"publicationDate":"2026-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148540812","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The analysis is grounded in an energy–economics interface, where energy consumption, pricing structures, and transition policies are treated as key economic drivers influencing profitability, capital allocation, and risk exposure across regions. A balanced provincial panel dataset is constructed to capture variations in economic performance indicators alongside financial risk measures under evolving policy and market conditions. To empirically examine these relationships, the study employs a dynamic panel econometric framework based on the two-step system Generalized Method of Moments (System GMM), which effectively addresses endogeneity, unobserved heterogeneity, and persistence in economic performance. Economic performance is proxied by indicators such as return on investment, value-added growth, and cost efficiency, while financial risk is quantified using volatility measures, leverage sensitivity, and downside risk proxies. The baseline specification incorporates lagged dependent variables and key explanatory factors including energy price fluctuations, energy intensity, capital structure, and policy uncertainty indices, allowing for a comprehensive assessment of both short-run adjustments and long-run equilibrium effects. The empirical findings reveal that energy-related economic activities exert a statistically significant and nonlinear influence on economic performance, with moderate levels of energy cost exposure enhancing efficiency, while excessive volatility in energy prices amplifies financial risk and erodes profitability. The results further indicate that financial risk is highly sensitive to policy uncertainty and carbon-related regulatory shifts, particularly in provinces undergoing rapid structural transformation. Regions with diversified economic structures and stronger financial development exhibit greater resilience, demonstrating lower risk transmission from energy price shocks to economic outcomes. Robustness checks using alternative estimators, including fixed-effects models with Driscoll–Kraay standard errors and quantile regression techniques, confirm the stability of the results across different distributional conditions. The study also identifies threshold effects, suggesting that beyond certain levels of energy price volatility, the marginal impact on financial risk increases disproportionately. These findings underscore the importance of stable policy frameworks and financial risk management strategies in sustaining economic performance.
