The presence of a definitive spatiotemporal correlation among the temperatures at various nodes within the battery is confirmed. Furthermore, a spatiotemporal correlation matrix for temperature responses is constructed using regularization optimization techniques. The temperature RSTCM for battery is established, which utilizes surface temperature measurement data to estimate the temperature distribution.

This study developed a comprehensive evaluation system including combustion characteristics, operational safety, and techno-economic analysis to reveal the interactions between components and mineral evolution during sewage sludge-high ash coal co-combustion. The results demonstrated that blending sewage sludge significantly improved the ignition performance of high ash coal. When the sewage sludge blending ratio exceeded 50 %, combustion transitioned from a fixed carbon-dominant to a volatile-dominated mode. A 50 % sewage sludge blend (sewage sludge to high ash coal mass ratio of 5:5) achieved a comprehensive combustion characteristic index of 4.80 × 10<sup>−8</sup>, representing a 100.58 % enhancement compared with coal. Synergistic interactions enhanced the combustion efficiency of fixed carbon, as evidenced by a 25.12 % increase in the fixed carbon weight-loss rate for the 60 % sewage sludge blend, compared to theoretical predictions. Minerals (CaO, Fe<sub>2</sub>O<sub>3</sub>, AlPO<sub>4</sub>) exhibited dual catalytic-inhibitory regulation: optimal concentrations enhanced combustion via catalytic cracking and oxygen storage-release mechanisms, while excessive minerals promoted slag formation impeding oxygen diffusion, with the efficacy hierarchy following CaO &gt; AlPO<sub>4</sub> &gt; Fe<sub>2</sub>O<sub>3</sub>. Ash chemistry analysis revealed that the addition of sewage sludge increased the alkaline oxide content, promoting silicate network depolymerization. At blending ratios exceeding 50 %, the ash deformation temperature sharply decreased to 1157 °C, increasing the risks of slagging. Economic evaluation indicated dynamic payback periods of 2.91 years for a 50 % blend and 7.67 years for a 60 % blend. Multi-objective optimization identified the optimal sludge-to-coal ratio as 5:5, achieving balanced improvements in combustion efficiency, ash fusion control, and economic viability.

THSs are first decomposed into components, whose surrogate models are constructed based on datasets collected from experiments or simulations. Component models are integrated to build the system model, which is finally used for system optimization. The optimization complexity is effectively reduced with the accuracy kept. Two cases are investigated for validation. A heat exchanger network with supercritical carbon dioxide is first considered with datasets generated from simulation. The obtained optimal design consumes 27.5% less power compared with that of the reference design. The robustness of optimization via the framework also outperforms the physics-based model substantially. An integrated cooling system with two operation modes is considered next with datasets collected from experiments. The optimal system operation guided by the system model reduces power consumptions by 47.3 and 36.4% under two modes.

This study investigates the role of advanced panelizing and optimization techniques in renewable energy projects, focusing on their potential to mitigate CO2 emissions and enhance the circular economy across ten countries: the United Kingdom, United States, China, Canada, India, Germany, Japan, Russia, Korea Republic, and Iran, over the period 1990–2024. The primary aim is to evaluate how CO2 emissions interact with renewable energy integration, resource efficiency, and waste minimization to foster a sustainable circular economy. Using a robust methodological framework, the study employs Hurlin causality evaluation to assess causative relationships, Dumitrescu's heterogeneous panel analysis for variability across regions, and panel-based fully modified least-squares methods to ensure consistency and reliability in long-term analysis. The findings reveal four key insights: (1) Renewable energy adoption significantly reduces CO2 emissions, particularly in high-emission economies like China, the United States, and India. (2) Circular economy initiatives are positively correlated with renewable energy use, with European nations like Germany and the United Kingdom demonstrating the strongest synergies. (3) Technological advancements in renewable energy yield more substantial emission reductions in developed nations, while emerging economies show slower but steady progress. (4) A decoupling effect between economic growth and CO2 emissions is observable in most countries, but remains limited in energy-intensive economies such as Iran and Russia. These results underscore the need for policymakers to incentivize renewable energy innovation, prioritize circular economy frameworks, and establish region-specific strategies to accelerate the transition towards a low-carbon, resource-efficient future.</div></div>","PeriodicalId":11647,"journal":{"name":"Energy","volume":"323 ","pages":"Article 135881"},"PeriodicalIF":9.0,"publicationDate":"2025-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143739720","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
