Although ambient mechanical energy is ubiquitously accessible, its practical utilization for powering electronic devices is constrained due to the low-frequency characteristics and low displacement amplitude of ambient mechanical energy. This work proposed dual frequency-up conversion (D-FUC) for enhanced low-frequency swing energy harvesting in a hybrid piezoelectric-electromagnetic harvester (HPEH). The D-FUC is composed of FUC₁ and FUC₂. FUC₁ implemented with a swing structure, an inextensible rope, and a static pulley, and FUC₂, enabled by a gear system. The D-FUC can convert low-frequency swing motion into high-frequency oscillations while addressing the low displacement amplitude of mechanical motion, demonstrating advantages in harvesting ambient mechanical energy. Furthermore, a dual-spiral spring configuration is implemented to enhance operational continuity in the energy harvesting system. The output voltage of the prototype at an 18° swing angle is comparable to that at a 90° swing angle. Additionally, benefiting from the non-contact excitation enabled by magnetic coupling, the risk of damage to the piezoelectric component is significantly reduced. The swing angle enhancement ratio (the ratio of output to input swing angles) reaches 9.72–10.64. Validation results show that the prototype, with optimized structural parameters, delivers an RMS output power of 3.52 mW. The D-FUC provides a novel frequency up-conversion mechanism.

虽然环境机械能无处不在，但由于环境机械能的低频特性和低位移幅值，限制了其在电子设备供电中的实际应用。本文提出了一种双频上转换（D-FUC）技术，用于增强混合压电-电磁收割机（HPEH）的低频摆动能量收集。D-FUC由FUC1和FUC2组成。FUC1采用摆动结构、不可伸缩绳索和静态滑轮，FUC2采用齿轮系统。D-FUC可以将低频摆动运动转换为高频振荡，同时解决机械运动的低位移幅值问题，在收集环境机械能方面具有优势。此外，采用了双螺旋弹簧结构，以提高能量收集系统的操作连续性。样机在18°摆角时的输出电压与90°摆角时的输出电压相当。此外，得益于磁耦合的非接触激励，压电元件的损坏风险大大降低。摆角增强比（输出与输入摆角之比）达到9.72 ~ 10.64。验证结果表明，在优化结构参数的情况下，样机的RMS输出功率为3.52 mW。D-FUC提供了一种新颖的频率上转换机制。

The review highlights that data-driven models, hybrid AI frameworks, and reinforcement learning-based controllers consistently outperform conventional rule-based strategies in terms of flexibility, responsiveness, and automation capability. The review also identifies key implementation factors for AI in NZEBs, including interpretability, hybrid architectures, computational effectiveness, system integration, model selection, data quality and preprocessing, and interpretation. The latest developments in AI-based NZEB research are also covered, including digital twins, explainable AI, federated and transfer learning, AI for retrofit and design optimization, and interpretable models. Furthermore, important issues and challenges are listed to denote areas that lack research on AI-enabled NZEB systems.

Accurate and interpretable wave height prediction is essential for advancing wave energy and marine renewable energy. This study proposes an explainable stacking ensemble machine learning framework for real-time and short-term significant wave height prediction. The framework constructs a diverse pool of nine candidate base learners from different algorithm families. Based on performance and correlation analysis, a representative subset is selected and aggregated using a linear regression meta-learner to enhance robustness. The framework is validated using 2016 observational data from NDBC buoys 41002 (North Atlantic) and 42055 (Gulf of Mexico). For real-time forecasting, the stacking ensemble consistently outperforms baseline models at both buoy sites, achieving the highest R² (0.9148 / 0.9391) and the lowest RMSE, MAE, and MSE values. It also maintains superior accuracy in short-term multi-step forecasting (1 h, 3 h, 6 h) compared to LSTM and TCN-LSTM, demonstrating strong robustness and generalization across varying time horizons. To ensure model transparency and practical trustworthiness, Shapley Additive Explanations (SHAP) are employed, enabling comprehensive interpretation of feature contributions and the relative influence of each base learner. By integrating SHAP with stacking ensemble learning, this study improves both the accuracy and interpretability of wave height prediction, supporting safer and more efficient use of marine resources.

准确和可解释的波高预测对于推进波浪能和海洋可再生能源至关重要。本研究提出了一种可解释的叠加集成机器学习框架，用于实时和短期有效波高预测。该框架构建了一个由来自不同算法族的9个候选基学习者组成的多样化库。基于性能和相关性分析，选择一个具有代表性的子集，并使用线性回归元学习器进行聚合，以增强鲁棒性。利用2016年NDBC浮标41002（北大西洋）和42055（墨西哥湾）的观测数据对该框架进行了验证。在实时预报方面，两个浮标点的叠加集合均优于基线模型，R2最高（0.9148 / 0.9391），RMSE、MAE和MSE值最低。与LSTM和TCN-LSTM相比，它在短期多步预测（1小时、3小时、6小时）中也保持了更高的准确性，在不同的时间范围内表现出很强的稳健性和泛化性。为了保证模型的透明度和实际可信度，采用Shapley加性解释（SHAP），可以全面解释特征贡献和每个基础学习器的相对影响。本研究通过将SHAP与叠加集成学习相结合，提高了波高预测的精度和可解释性，支持更安全、更有效地利用海洋资源。

Greenhouse gas emissions from sustainable aviation fuel production are quantified from a life cycle assessment perspective, assuming domestic resources in South Korea, i.e., microalgae and food waste, processed via hydroprocessed esters and fatty acids pathway. The results indicate that under current technological conditions, sustainable aviation fuel production through this pathway results in 84.7–94.2 gCO_2eq/MJ of greenhouse gas emissions, compared to 85.1 gCO_2eq/MJ for conventional fossil-based jet fuel. Therefore, these alternatives are not yet favorable decarbonization options, given their marginal improvement or even potential worsening of emissions. A detailed process-level breakdown is provided to emphasize the need for technical advancements across the production chain. Significant greenhouse gas reductions could be achieved by lowering the carbon intensity of the national electricity grid, resulting in as much as 24 gCO_2eq/MJ reduction, and addressing methane leakage during energy recovery step to reduce another 8 gCO_2eq/MJ, as the key production processes are highly energy-intensive. With the implementation of the proposed improvements, net greenhouse gas emissions could be substantially reduced, making these alternative fuels a more viable and attractive solution for the South Korean aviation sector.

从生命周期评估的角度对可持续航空燃料生产的温室气体排放进行量化，假设韩国国内资源，即微藻和食物垃圾，通过加氢加工酯和脂肪酸途径进行加工。结果表明，在现有技术条件下，通过该途径生产可持续航空燃料的温室气体排放量为84.7-94.2 gCO2eq/MJ，而传统化石燃料的温室气体排放量为85.1 gCO2eq/MJ。因此，这些替代方案还不是有利的脱碳选择，考虑到它们的边际改善甚至可能加剧排放。提供了详细的过程级分解，以强调对整个生产链的技术进步的需求。通过降低国家电网的碳强度，可以实现显著的温室气体减排，减少多达24 gCO2eq/MJ，并解决能源回收步骤中的甲烷泄漏，可以减少另外8 gCO2eq/MJ，因为关键的生产过程是高能耗的。随着所提出的改进措施的实施，温室气体净排放量可以大大减少，使这些替代燃料成为韩国航空业更可行和更有吸引力的解决方案。

This study experimentally investigates the influence of slot mechanisms on the power performance of a small-scale horizontal-axis wind turbine (ss-HAWT). A total of five rotor blade configurations were evaluated, including a baseline model (B1) and four slot-modified variants (M1–M4), each incorporating full- or partial-span (based on root-based, tip-based) slot geometries at distinct spanwise locations. The implemented slot mechanism was defined by three novel slot radii, the slot inlet pressure side radius (r_p), the slot outlet suction side radius (r_t), and the Coanda radius (r_c), which were designed. Experiments were conducted in an open-test-section, blowing-type wind tunnel under two rotational speeds (300 and 400 rpm). Surface oil flow visualization (SOFV) was employed to analyze the blade surface flow topologies and identify regions of attached flow on both suction and pressure sides. The M1 configuration, featuring a full-span slot configuration, consistently demonstrated superior power coefficient (C_P) values across all tip speed ratio (λ or TSR) values at 300 rpm. The full-span slot design (M1) yielded a maximum C_P of 0.46 at λ = 3.9, corresponding to a 9.5 % improvement over B1 at 400 rpm. The results revealed that slot integration notably delayed flow separation and promoted surface attachment, particularly in the tip region, thereby extending high-efficiency operation to higher TSR regimes. The findings confirm that strategically slot mechanisms offer a robust aerodynamic improvement for ss-HAWT.

实验研究了狭缝机构对小型水平轴风力机（ss-HAWT）动力性能的影响。总共评估了五种旋翼叶片配置，包括基线模型（B1）和四种改进型（M1-M4），每一种都在不同的展向位置包含全跨度或部分跨度（基于根部和尖端）的槽几何形状。所实现的狭缝机构由三种新型狭缝半径定义，即狭缝进口压力侧半径（rp）、狭缝出口吸力侧半径（rt）和康达半径（rc）。实验在开式试验段吹式风洞中进行，转速分别为300和400 rpm。采用表面油流可视化（SOFV）技术对叶片表面流动拓扑结构进行分析，识别叶片吸力侧和压力侧附着流动区域。M1配置具有全跨槽配置，在300 rpm时，在所有叶尖速比（λ或TSR）值中始终显示出优越的功率系数（CP）值。全跨度槽设计（M1）在λ = 3.9时的最大CP为0.46，相当于在400 rpm时比B1提高9.5%。结果表明，狭缝集成显著延迟了流动分离，促进了表面附着，特别是在尖端区域，从而将高效率的操作扩展到更高的TSR区域。研究结果证实，策略性的狭缝机构为ss-HAWT提供了强大的空气动力学改进。

This study provides a national-scale projection of China’s photovoltaic (PV) potential by combining CMIP6 model accuracy assessment with long-term turning-point detection. Based on rate-of-change evaluation against historical observations, four models (ACCESS-CM2, ACCESS-ESM1.5, IPSL-CM6A-LR, and KIOST-ESM) are identified as most reliable, and their ensemble mean (MM4) is used to examine PV potential from 1984 to 2100. Under low- and medium-emission scenarios, PV potential shows sustained growth with turning points around 2034 and 2028. In contrast, under the high-emission SSP585 scenario, MM4 reveals a critical turning point in 2035 followed by a multi-decadal decline until 2094, driven by a dual temperature-induced constraint: direct reductions in PV module efficiency and indirect suppression of surface irradiance through enhanced water vapor and cloud optical effects. These radiative feedbacks ultimately dominate the long-term trajectory of PV potential under SSP585. Compared with MM4, the remaining models (MM11) yield more optimistic projections but likely overestimate future PV potential. Overall, the identified turning points reflect a shift from aerosol-driven brightening to warming-driven declines, underscoring the need for high-accuracy models and adaptive strategies under high-emission pathways.

本研究通过将CMIP6模型精度评估与长期拐点检测相结合，提供了中国光伏（PV）潜力的国家尺度预测。基于对历史观测值的变化率评估，确定了4个模型（ACCESS-CM2、ACCESS-ESM1.5、IPSL-CM6A-LR和KIOST-ESM）最可靠，并使用它们的集合平均值（MM4）对1984 - 2100年的光伏势进行了研究。在中、低排放情景下，光伏潜力呈现持续增长态势，并在2034年和2028年左右出现拐点。相比之下，在高发射SSP585情景下，MM4在2035年出现一个关键转折点，随后在2094年之前出现多年代际下降，这是由温度诱导的双重约束驱动的：光伏组件效率的直接降低，以及通过增强水汽和云光学效应间接抑制表面辐照度。这些辐射反馈最终主导了SSP585下PV电位的长期轨迹。与MM4相比，其余模型（MM11）给出了更乐观的预测，但可能高估了未来的光伏潜力。总体而言，确定的转折点反映了从气溶胶驱动的增白到变暖驱动的下降的转变，强调了在高排放途径下高精度模型和适应策略的必要性。

Overall, the identified turning points reflect a shift from aerosol-driven brightening to warming-driven declines, underscoring the need for high-accuracy models and adaptive strategies under high-emission pathways.</div></div>","PeriodicalId":56019,"journal":{"name":"Sustainable Energy Technologies and Assessments","volume":"85 ","pages":"Article 104783"},"PeriodicalIF":7.0,"publicationDate":"2025-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145791958","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}

The limited driving range of electric vehicle (EV) on long distance travel, such as highways, is a major barrier to their widespread adoption. The construction of highway charging stations has been an important development plan for governments. Analyzing and simulating the charging load on highways is essential for supporting the development of EV charging station and infrastructure. This paper examines the spatiotemporal distribution of highway traffic flow using a modified Cell Transmission Model, which is based on the fluid dynamics of traffic flow. Additionally, a charging load simulation method designed to handle excessive charging demand periods is introduced, utilizing the Stationary Backlog Carryover approach. This method effectively simulates the continuous backlog of EVs charging demand that frequently occurs during holidays and peak periods. The validity of the proposed method is demonstrated using data from a highway in Shandong, China, highlighting its potential to support EV infrastructure planning and pricing strategy.

电动汽车在高速公路等长途行驶中的行驶里程有限，是其广泛采用的主要障碍。高速公路充电站建设一直是各国政府的重要发展规划。高速公路充电负荷分析与仿真是支持电动汽车充电站和基础设施建设的必要手段。本文采用基于交通流流体动力学的改进细胞传输模型研究了公路交通流的时空分布。此外，还介绍了一种利用静止积压结转方法处理超长充电需求期的充电负荷仿真方法。该方法有效地模拟了节假日和高峰时段频繁出现的电动汽车充电需求持续积压现象。通过山东高速公路的数据验证了该方法的有效性，强调了其支持电动汽车基础设施规划和定价策略的潜力。

To address the issues of high-pressure gaseous hydrogen storage occupying large space and potential safety hazards such as leakage, underground hydrogen storage technology using hydrates has been widely regarded for its ability to provide large-scale, safe, efficient and long-term hydrogen storage solutions. This paper innovatively overcomes the limitations of traditional single-dimensional studies by constructing a cross-scale integration quantitative coupling relationship of “nucleation kinetics − phase characteristics − reservoir optimization.” Firstly, it clarifies the phase characteristics and temperature–pressure conditions of hydrogen hydrates, providing theoretical data for hydrogen storage applications; secondly, it focuses on kinetic mechanisms in bulk and confined spaces, revealing the synergistic effects of “pore size − surface hydrophilicity/hydrophobicity − fluid mobility” on nucleation in confined spaces; finally, it summarizes the mechanisms of hydrate-based hydrogen storage under reservoir conditions (marine reservoirs and permafrost layers). This innovation significantly differs from previous studies: earlier studies often investigated nucleation, phase characteristics, or reservoirs in isolation, and paid insufficient attention to the coupling effects of multiple factors in confined spaces and differentiated reservoir optimization. The main contribution of this research is the establishment of universal theoretical framework and differentiated strategies, providing key technical references and research paradigms for subsequent reservoir optimization and industrial applications.

针对高压气体储氢占用空间大、泄漏等安全隐患大的问题，利用水合物的地下储氢技术因其能够提供大规模、安全、高效、长期的储氢解决方案而受到广泛重视。本文创新性地建立了“成核动力学-相特征-储层优化”的跨尺度积分定量耦合关系，克服了传统单维研究的局限性。首先，阐明了氢水合物的物相特征和温压条件，为储氢应用提供了理论数据；其次，重点研究了体积和密闭空间的动力学机制，揭示了“孔径-表面亲疏水性-流体迁移率”对密闭空间成核的协同作用；最后，总结了储层条件下（海洋储层和永久冻土层）水合物储氢机理。这一创新明显不同于以往的研究，以往的研究往往是孤立地研究成核、相特征或储层，而对密闭空间中多因素的耦合效应和差异化储层优化关注不足。本研究的主要贡献是建立了通用的理论框架和差异化策略，为后续的储层优化和产业应用提供了关键的技术参考和研究范式。

Setting up upstream double surge chambers (UDSC) is an effective pressure-mitigation arrangement for hydropower station with long headrace tunnel (HSLHT), and determining their critical stable sectional areas is essential for stable operation. This paper establishes the stability analysis model of HSLHT with UDSC. The stable domain of sectional areas of UDSC is drawn, and the inflection point corresponding to the minimum stable sectional area (F_c_2min) of primary surge chamber (PSC) is proposed. The boundary curve of the stable domain consists of two curves intersecting at the inflection point, indicating the sectional area of PSC must be greater than F_c₂_min to ensure stability. Furthermore, the dynamic characteristics at the stable domain boundary are revealed. The water level oscillation of PSC is the superposition of the low-frequency oscillation mode with large amplitudes and medium-frequency oscillation mode with small amplitudes. Subsequently, the influence of the setting position of secondary surge chamber (SSC) on the stable domain is analyzed. As the SSC sets closer to PSC, F_c_2min remains almost unchanged, while the corresponding stable sectional area of SSC decreases significantly. Finally, the analytical formula for the inflection point and design principle of stable sectional areas of UDSC are presented, providing support for engineering design.

设置上游双调压室是长水头隧洞水电站的一种有效降压布置，确定其临界稳定截面积是保证长水头隧洞稳定运行的关键。本文建立了带UDSC的HSLHT稳定性分析模型。绘制了UDSC截面积的稳定域，提出了主调压室（PSC）最小稳定截面积（Fc2min）对应的拐点。稳定域的边界曲线由两条在拐点相交的曲线组成，说明PSC的截面积必须大于Fc2min才能保证稳定。此外，还揭示了稳定域边界处的动态特性。PSC的水位振荡是大振幅低频振荡模态和小振幅中频振荡模态的叠加。随后，分析了二次调压室设置位置对稳定域的影响。随着SSC离PSC越近，Fc2min基本保持不变，而相应的SSC稳定截面积明显减小。最后给出了UDSC的拐点解析公式和稳定截面积的设计原则，为工程设计提供了依据。

This article presents the main results of a three-year R&D program on the coupling of a Small Modular Reactor (SMR) nuclear unit to a hydrogen production process using High-Temperature Steam Electrolysis (HTSE). Different coupling architectures are investigated and their energetic evaluation is performed in comparison with a reference configuration. The separate effects that are considered are comprehensive and include: thermal coupling (with or without, unidirectional or bidirectional − modulo internal heat recovery effort in the HTSE process itself), direct or indirect steam supply, location of the Rankine cycle extraction point, pressurization of the HTSE (with or without mechanical energy recovery through gas expansion) and oxygen content (impact of the swept gas). Remarkably, the simulation results obtained on the reference configuration show a gain of over 13% in hydrogen production compared with the solution involving no thermal coupling between the SMR and the HTSE process (when HTSE heat is provided through electrical heaters), with a deviation as low as 3 % from an idealized configuration with freely available heat. It even outperforms the heat-pump solution by more than 4 %. These key energetic results were supplemented by other technical criteria, such as those relating to safety and technological maturity.

本文介绍了一项为期三年的研发计划的主要成果，该计划将小型模块化反应堆（SMR）核机组与高温蒸汽电解（HTSE）制氢过程耦合在一起。研究了不同的耦合结构，并与参考结构进行了能量评价。考虑的单独影响是全面的，包括：热耦合（有或没有，HTSE过程本身的单向或双向-模内部热回收努力），直接或间接蒸汽供应，朗肯循环萃取点的位置，HTSE的加压（通过气体膨胀有或没有机械能回收）和氧含量（扫气的影响）。值得注意的是，在参考配置上获得的模拟结果显示，与SMR和HTSE过程之间没有热耦合的解决方案（当HTSE热量通过电加热器提供时）相比，产氢的增益超过13%，与具有自由可用热量的理想配置偏差低至3%。它甚至比热泵解决方案高出4%以上。这些关键的有力结果得到其他技术标准的补充，例如与安全和技术成熟度有关的标准。
