Anchored in the tri-axis of <em>materials – mechanisms – hotspots/trends</em>, this review systematically analyses the structure-property-performance relationships of five emerging classes of nanomaterials—COFs, MOFs, MXenes, PCMs and flaccid antiferroelectrics—in battery and capacitor configurations. Drawing on more than 300 recent publications, we construct a unified evaluation framework built around ten intrinsic parameters—pseudocapacitance, structural gradients/disorder, bond-length or interlayer-spacing regulation, high specific surface area, vacancy effects, ion solubility, dielectric breakdown strength, doping effects, electron-transfer effects and high-entropy strategies—and benchmark them against practical engineering metrics such as energy density, power density, cycle stability and safety. Within this framework, we distil five current research hotspots—biochemical energy storage, supercapacitors, dielectric capacitors, information encryption &amp; decryption, and machine learning &amp; programming—and relate them to five emerging trends: (i) anti-corrosion and acid/alkali-resistant materials, (ii) battery operation under extreme conditions, (iii) fast-charging capability, (iv) wearable and flexible energy-storage systems, and (v) next-generation storage batteries. These insights illustrate how evolving application demands are reshaping both material selection and evaluation strategies. Finally, we outline four strategic directions—green scalable synthesis, in-situ high-throughput characterization, data-driven materials design and device-level integration—that can accelerate the optimization and deployment of novel energy-storage nanomaterials. By providing an actionable assessment toolbox and a forward-looking roadmap, this review aims to guide the rational ranking of material candidates and engineering approaches toward the next generation of sustainable EES systems.</div></div>","PeriodicalId":418,"journal":{"name":"Renewable and Sustainable Energy Reviews","volume":"224 ","pages":"Article 116093"},"PeriodicalIF":16.3,"publicationDate":"2025-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144679754","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}

Industry stakeholders have responded with various strategies, such as optimizing existing power plants, improving energy efficiency, and developing innovative power plant designs utilizing alternative fuels. In light of the global pressure to transition to cleaner maritime operations, this study evaluates five sustainable fuel alternatives for icebreakers - LNG, methanol, ammonia, hydrogen, and nuclear energy - in comparison to diesel, with the aim to balance operational power needs, life cycle costs, and increasingly strict environmental regulations. The results indicate that the Small Modular Reactor (SMR) is a highly promising energy source, combining technical feasibility and economic viability, with lifecycle costs 14.9 M€ lower and emissions 80% less than the next best option. A key benefit is its ability to generate electricity profitably, providing additional revenue during off-season periods. Moreover, for the operational profile of icebreakers, methanol and ammonia are emerging as feasible options, enabling a path toward a cleaner future without requiring excessive tank volume. All hydrocarbons can be produced from either fossil-based or renewable carbon sources, offering flexibility for investment in engines that can transition to sustainably produced fuels without requiring engine modifications. This transition can be timed strategically, considering the cost dynamics of sustainable fuels and evolving emissions regulations.

However, RCx studies and applications are not as prevalent as those in the other building energy related domains. The past and recent states of RCx research have not been thoroughly investigated, and future research directions remain unclear. Therefore, a review is conducted to address these gaps using a systematic-cascade approach that includes: retrieval of RCx publications from the ScienceDirect and Scopus databases; bibliometric analysis of the publications using the VOSviewer software; in-depth qualitative analysis of key RCx publications and real case studies; and expert validation of the analysed findings. Key results include the identification of the regions of the past RCx studies, types of buildings and building systems investigated, data types, and data collection and analysis methods used in the studies. Distinct from the continual growth of research in the building energy domain, there was no discernible trend of RCx research. Among the past studies utilizing empirical data, universities and schools are mainly selected for testing RCx scenarios or hypotheses. Barriers and enablers for RCx implementation were found to fall into six categories: knowledge, manpower, finance, motivation, time, and data/information. Nine research gaps and corresponding future research directions were also identified. In addition to contributing to the existing body of RCx knowledge, the results of this study serve as a reference for RCx stakeholders and offer guidance for researchers to pursue further RCx studies.</div></div>","PeriodicalId":418,"journal":{"name":"Renewable and Sustainable Energy Reviews","volume":"224 ","pages":"Article 116116"},"PeriodicalIF":16.3,"publicationDate":"2025-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144672231","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}

We develop an economically optimized model tailored for major CO₂-emitting regions, covering the period from 2030 to 2050. The proposed model outlines a structured CCU4E strategy by identifying the optimal pathway configurations under nation-specific constraints such as H₂ production costs, market demand variability, and CO₂ capture capacities. Our analysis reveals that CCU4E strategies demonstrate significant potential for CO₂ utilization, with substantial regional variations driven by differences in H₂ availability and H₂ price. The economic feasibility and environmental performance vary considerably across regions, with H₂ price identified as the dominant economic factor. Policy sensitivity analysis demonstrates that carbon taxes, H₂ economy promotion, and catalyst development significantly influence CCU4E effectiveness, with optimal strategies varying substantially by regional conditions. Synergistic integration of CCU4E with existing CCUS frameworks offers strategic pathways for enhanced CO₂ mitigation while improving economic efficiency. The comprehensive optimization framework provides practical insights for policymakers and industry stakeholders by identifying implementation barriers, quantifying economic potential, and developing targeted policy recommendations.

Additionally, it suggests utilizing machine learning to forecast the properties of HTC-AP. The characteristics of HTC-AP are closely linked to the chemical properties of the sludge and parameters of the HTC process, with higher proportions of high-nitrogen sludge and higher temperatures correlating with increased toxicity. Detoxification is essential before HTC-AP recycling. Achieving the full treatment and recycling of HTC-AP in a single process is challenging and necessitates greater integration and synergy between systems.
