Sustainable energy transition, particularly via the use of electric vehicles (EVs), is a prominent solution to address the environmental challenges. A catalyst for this transformation is the ability to manufacture autonomous lithium-ion batteries (LIBs), a vital component for EVs. Leading countries are competing to ensure an independent and autonomous supply of raw materials necessary for this energy shift, especially for nickel manganese cobalt oxide (NMC) chemistry, a significant cathode for LIBs. Morocco, a North African country, has a large production capacity for NMC raw materials, including nickel, manganese, and cobalt, but these resources are mostly exported in their raw or intermediate forms without significant valorisation to meet the NMC cathode requirements. To mitigate this challenge, this article develops refining processes that valorise actual mineral resources to produce the battery-grade precursors necessary for NMC cathodes. A rigorous examination of earlier studies found that sulphate precursors are the main metal sources used to make NMC cathodes in both research and industry. Refining processes have been established to transform natural manganese ore into a high-purity manganese sulphate precursor. Regarding nickel and cobalt sulphate, transformational processes were developed by adapting existing facilities. These processes will enable Morocco to produce 600 metric tonnes of nickel sulphate, 9305 metric tonnes of cobalt sulphate, and 56,160 metric tonnes of manganese sulphate, which in turn allows the manufacture of almost 370,000 EVs. This work paves the way for Morocco to valorise its mineral resources and develop an integrated industrial ecosystem for the EVs supply chain.

可持续能源转型，特别是通过使用电动汽车（ev），是应对环境挑战的重要解决方案。这种转变的催化剂是制造自动锂离子电池（lib）的能力，这是电动汽车的重要组成部分。主要国家正在竞相确保这种能源转变所需的原材料的独立和自主供应，特别是镍锰钴氧化物（NMC）化学，这是锂离子电池的重要阴极。摩洛哥是一个北非国家，拥有大量的NMC原材料生产能力，包括镍、锰和钴，但这些资源大多以原料或中间形式出口，没有显着增值以满足NMC阴极的要求。为了缓解这一挑战，本文开发了一种精炼工艺，使实际矿产资源增值，以生产NMC阴极所需的电池级前体。对早期研究的严格检查发现，硫酸盐前体是研究和工业中用于制造NMC阴极的主要金属来源。建立了将天然锰矿石转化为高纯度硫酸锰前驱体的精炼工艺。对于镍和硫酸钴，通过改造现有设施开发了改造工艺。这些工艺将使摩洛哥能够生产600公吨硫酸镍、9305公吨硫酸钴和56160公吨硫酸锰，从而可以生产近37万辆电动汽车。这项工作为摩洛哥实现矿产资源增值和为电动汽车供应链开发综合工业生态系统铺平了道路。

This study aims to forecast methane (CH₄) and nitrous oxide (N₂O) emissions from cattle rearing in India, which contribute significantly to agricultural greenhouse gas (GHG) emissions. Data on these emissions was collected from the Food and Agricultural Organization for the years 1961–2022. Three time series models, namely, exponential smoothing (Holt-Winters), autoregressive integrated moving average (ARIMA), and trigonometric seasonality, Box-Cox transformation, ARMA errors, trend, and seasonal components (TBATS) were employed to predict future emissions. The dataset was partitioned into training (1961–2012) and testing (2013–2022) sets to evaluate model performance. Diagnostic metrics, including Akaike Information Criterion, root mean square error, mean absolute percentage error, and mean absolute scaled error, were used to assess accuracy. Results indicated that the ARIMA model outperformed the other 2 forecasting models by making over 90% accurate predictions. For N₂O, ARIMA (0,1,0) was identified as the optimal model, while ARIMA (2,1,2) was selected for CH₄. Thus, the study validates the use of ARIMA model in GHG forecasting. The study projects emissions up to 2030, providing critical insights for policymakers to design targeted mitigation strategies. The study also presses the need for implementing sustainable cattle management practices for cutting emissions in India.

本研究旨在预测印度养牛过程中甲烷（CH₄）和氧化亚氮（N₂O）的排放，这两种气体对农业温室气体（GHG）排放有很大贡献。这些排放的数据是从联合国粮农组织1961年至2022年收集的。采用指数平滑（Holt-Winters）、自回归综合移动平均（ARIMA）和三角季节性、Box-Cox变换、ARMA误差、趋势和季节分量（TBATS） 3种时间序列模型对未来排放进行预测。数据集被划分为训练集（1961-2012）和测试集（2013-2022），以评估模型的性能。诊断指标包括赤池信息标准、均方根误差、平均绝对百分比误差和平均绝对比例误差，用于评估准确性。结果表明，ARIMA模型的预测准确率在90%以上，优于其他2种预测模型。对于N₂O，最优模型为ARIMA(0,1,0)，而对于CH₄，最优模型为ARIMA（2,1,2）。因此，本研究验证了ARIMA模型在温室气体预测中的应用。该研究预测了到2030年的排放量，为政策制定者设计有针对性的减排战略提供了关键见解。该研究还强调了在印度实施可持续的养牛管理措施以减少排放的必要性。

Sodium-ion batteries (SIBs) are being actively investigated as a potentially viable and more sustainable alternative to lithium-ion batteries (LIBs), driven by concerns over lithium resource scarcity, high production costs, and environmentally challenging extraction methods. While LIBs dominate applications in consumer electronics and electric vehicles due to their superior energy density and maturity, SIBs offer notable advantages, such as using earth-abundant and low-cost elements like sodium and aluminum. Despite current limitations in energy density and cycle life, ongoing research in electrode materials and cell design has yielded encouraging progress in enhancing the electrochemical performance and safety profile of SIBs. In particular, their improved thermal stability offers potential benefits for stationary energy storage applications where safety is critical. The development of SIBs aligns with global Sustainable Development Goals (SDGs), particularly SDG 7 (Affordable and Clean Energy) and SDG 13 (Climate Action), by promoting safer and potentially lower-cost energy storage technologies. Continued advancements in material innovation, system integration, and end-of-life recycling will be key to the commercial competitiveness of SIBs. This review emphasizes the potential of SIBs as a viable alternative to LIBs by integrating electrochemical, economic, and environmental perspectives amid growing concerns over lithium supply and cost. For sustainable energy solutions and provides valuable insights into the current state of SIB research, offering a roadmap for future developments in this field.

Benthic plant microbial fuel cells (BPMFCs) represent an innovative, sustainable technology that effectively integrates plant photosynthesis with microbial electroactivity, facilitating the generation of renewable electricity alongside the remediation of organic waste. This study offers a critical analysis of the latest developments in BPMFC technology, focussing on 4 essential aspects: (1) novel bio-based electrode materials including functionalised conductive polymer composites, nanomaterial hybrids that enhance electron transfer (ET) efficiency; (2) advanced metagenomic and transcriptomic studies elucidating the electroactive microbial consortia and their unique extracellular ET mechanisms in both rhizosphere and BPMFC configurations; (3) the application of genetically modified plants with enhanced root exudation profiles, increasing power output; (4) innovative remote monitoring systems for BPMFCs employing IoT-enabled wireless sensor networks and long range wide area network technology ensuring reliable voltage measurement transmission from distant locations with minimal signal loss. The review rigorously analyses life cycle assessment studies that substantiate the environmental advantages of PMFCs, especially their carbon-negative potential when combined with wastewater treatment. Even with these advancements, there are still considerable obstacles to overcome in scaling BPMFC technology, such as concerns regarding system durability and questions about economic feasibility. A comprehensive roadmap is provided that integrates artificial intelligence-optimized material design, synthetic microbial community engineering, improved monitoring systems, and circular economy concepts to facilitate the transition from laboratory-scale prototypes to real-world applications. This analysis highlights the promise of BPMFCs as distributed renewable energy systems, particularly in agricultural and aquatic environments, while delineating critical research avenues to tackle existing commercialization obstacles.

While colocation of solar photovoltaic (PV) and strawberry cultivation has shown promise, the impact of different types of illumination on plant growth remains uncertain. To provide information to strawberry agrivoltaic system designers, this study performs a comparative analysis of strawberry cultivation under 1) uniform illumination provided by thin-film cadmium telluride (Cd-Te) with 30%, 40% and 70% transparent PV modules and 2) non-uniform semitransparent crystalline silicon (c-Si) with 25% (red - using a red dye for spectral changes), 44% (clear) and 69% (clear) transparent bifacial PV modules, which include rows of solar cells and transparent glass elements. All systems were assessed in a controlled biome that simulated the outdoor conditions of London, ON, using regulated temperatures. The strawberry fresh weight, plant height, leaf count, and flower count were quantified under each agrivoltaic system, and economics were analyzed. The results show that higher strawberry yields were consistently observed under non-uniform shading of c-Si semi-transparent PV compared to uniform thin-film PV. Specifically, while 70% uniformly transparent Cd-Te PV module resulted in 140.6% of the average control fresh weight, non-uniformly 69% transparent c-Si PV achieved a maximum fresh weight of 201.4%, more than the average control. Coupled to the economic value of the PV generation, the Canadian strawberry agrivoltaics sector could generate more than twice the revenue from traditional strawberry farming alone. These results underscore the dual benefits of agrivoltaics to both enhance agricultural productivity while achieving substantial clean energy production.

虽然太阳能光伏（PV）与草莓种植的搭配已经显示出前景，但不同类型的照明对植物生长的影响仍不确定。为了给草莓农业光伏系统设计者提供信息，本研究对草莓栽培进行了对比分析：1)薄膜碲化镉（Cd-Te）提供30%、40%和70%透明光伏组件的均匀照明，2)非均匀半透明晶体硅（c-Si）提供25%（红色-使用红色染料进行光谱变化）、44%（透明）和69%（透明）透明双面光伏组件。其中包括一排排太阳能电池和透明玻璃元件。所有系统都在一个受控的生物群落中进行评估，该生物群落模拟了伦敦的室外条件，使用调节的温度。对各光伏系统下草莓鲜重、株高、叶数和花数进行量化，并进行经济分析。结果表明，与均匀薄膜PV相比，非均匀遮光c-Si半透明PV下草莓产量始终较高。具体而言，70%均匀透明的Cd-Te光伏组件的鲜重为对照平均鲜重的140.6%，而非均匀透明的69% c-Si光伏组件的最大鲜重为201.4%，高于对照平均鲜重。再加上光伏发电的经济价值，加拿大草莓农业发电部门的收入可能是传统草莓种植的两倍多。这些结果强调了农业发电的双重好处，既提高了农业生产力，又实现了大量的清洁能源生产。

Induction heating (IH) holds a pivotal role in heating technology due to its numerous advantages such as simple, contactless, fast operation, environmentally friendly, and cost-effective nature. Domestic induction cooking (IC) is one of the most popular applications of IH. It is due to its safety, quick heating, cleanliness, and controllability. This paper presents a full-bridge resonant inverter with diode and series switch per load for multiload IC system using asymmetrical voltage cancellation (AVC) control with constant switching frequency. The advantages of this inverter circuit with AVC control include independent power control, high efficiency, wider output power range, soft-switching, and suitable for high-frequency loads. It can be seamlessly scaled to accommodate ‘n’ loads by integrating a diode and series switch combination for every new load. This configuration has been simulated using orcad personal simulation program with integrated circuit emphasis and validated through an experimental setup, generating 1108 W with a peak efficiency of 95.9%. The simulation and experimental results confirm that this inverter configuration is a viable approach for multiload IC applications.

The global shift toward renewable energy has intensified the need to improve photovoltaic (PV) efficiency, particularly in tropical climates where elevated temperatures degrade performance. This study evaluates 2 passive cooling methods, bio-based phase change materials (PCMs) and barium sulphate (BaSO₄) radiative cooling paint to mitigate PV overheating. Two eutectic PCM mixtures, lauric acid/oleic acid (LA/OA) and lauric acid/capric acid (LA/CA), were characterized via differential scanning calorimetry, revealing latent heats of 120.1 J/g and 172.1 J/g, respectively. Under simulated solar irradiance of 800 W/m², PCM-integrated panels demonstrated significant thermal regulation, with the LA/CA system reducing peak temperatures by 18.3 °C vs. the reference panel and improving power output by 26.0%. In contrast, radiative cooling paint applied to panel frames or side-mounted heat sinks lowered temperatures by up to 6.1 °C but unexpectedly reduced power generation due to power dissipation, highlighting a trade-off between thermal and electrical performance. The LA/CA PCM emerged as the superior solution for tropical climates, offering sustained cooling and enhanced efficiency, while paint formulations require further optimization to avoid compromising light absorption. This study provides critical insights into passive cooling strategies, emphasizing the importance of holistic performance evaluation for real-world PV applications.

全球向可再生能源的转变加剧了提高光伏（PV）效率的需要，特别是在热带气候中，高温会降低性能。本研究评估了两种被动冷却方法，即生物基相变材料（PCMs）和硫酸钡（BaSO₄）辐射冷却涂料，以减轻PV过热。采用差示扫描量热法对两种共晶PCM混合物月桂酸/油酸（LA/OA）和月桂酸/癸酸（LA/CA）进行了表征，潜热分别为120.1 J/g和172.1 J/g。在800 W/m²的模拟太阳辐照度下，集成pcm的面板显示出显著的热调节，与参考面板相比，LA/CA系统将峰值温度降低了18.3 °C，并将功率输出提高了26.0%。相比之下，应用于面板框架或侧面安装的散热器的辐射冷却涂料可将温度降低6.1 °C，但由于功率耗散，意外地减少了发电量，突出了热和电气性能之间的权衡。LA/CA PCM成为热带气候的卓越解决方案，提供持续的冷却和提高效率，而涂料配方需要进一步优化，以避免影响光吸收。这项研究为被动冷却策略提供了重要的见解，强调了对实际光伏应用进行整体性能评估的重要性。

Transportation electrification and the rapid deployment of distributed energy resources (DERs), including photovoltaics and battery energy storage systems, are transforming distribution grid operations. Traditional static hosting capacity assessments often fail to capture the dynamic, stochastic behavior of high DER penetrations, particularly when electric vehicles are integrated. This study applies a dynamic hosting capacity framework to a representative New England feeder using time-series simulations across five DER scenarios: baseline, unmanaged, time-of-use pricing, DER management systems (DERMS), and DERMS + vehicle-to-grid (V2G). Results reveal that unmanaged DERs more than double the factor of accelerated aging (FAA) in 18% of transformers and cause feeder voltage violations in 6.7% of operating hours. In contrast, DERMS coordination reduces voltage violations by 93% and FAA by over 50%. Hosting capacity increases from 25% under unmanaged conditions to 60% with DERMS + V2G. Dynamic hosting margin analysis indicates operational headroom rising from 18% (unmanaged) to over 40% (DERMS + V2G), with voltage regulator tap changes falling by 38% and reverse power flow events falling by 67%. These findings demonstrate that active coordination and V2G integration can substantially expand DER hosting capacity and enhance grid resilience without immediate infrastructure upgrades.

交通电气化和分布式能源（DERs）的快速部署，包括光伏和电池储能系统，正在改变配电网的运营。传统的静态承载能力评估往往无法捕捉高DER渗透的动态、随机行为，尤其是在集成电动汽车的情况下。本研究将动态托管容量框架应用于具有代表性的新英格兰馈线，使用时间序列模拟五种DER方案：基线，非管理，使用时间定价，DER管理系统（DERMS）和DERMS +车辆到电网（V2G）。结果表明，在18%的变压器中，未管理的der使加速老化（FAA）因素增加了一倍以上，并在6.7%的运行时间内导致馈线电压违规。相比之下，DERMS协调减少了93%的电压违规，减少了50%以上的FAA。托管容量从非托管条件下的25%增加到DERMS + V2G的60%。动态托管余量分析表明，运行净空从18%（非管理）上升到40%以上（DERMS + V2G），电压调节器分接变化下降38%，反向潮流事件下降67%。这些研究结果表明，主动协调和V2G集成可以在无需立即升级基础设施的情况下大幅扩展DER托管容量并增强电网弹性。

The valorisation of aluminium dross for hydrogen production offers a sustainable waste-to-energy pathway. This study examines hydrogen evolution from aluminium dross in aqueous NaOH and KOH (0.25–1.0 M) at 40–70 °C, measuring it as a function of time and using 3D contour mapping to determine initial rates and cumulative yields. Hydrogen evolution rises with alkali concentration and temperature; NaOH produces higher rates and volumes at lower conditions, while KOH exhibits steadier temperature-driven increases. The kinetic study reveals that the Avrami-Erofeyev model provides the best fit to the experimental data, showing excellent linearity (R² = 0.95–0.99). The calculated reaction orders (n = 0.88–1.23) indicate a near first-order behaviour consistent with nucleation-growth mechanisms. Arrhenius analysis gives activation energies of 63.07 kJ/mol (0.5 M NaOH) and 73.62 kJ/mol (0.5 M KOH), highlighting differing mechanistic regimes. This work frames dross recycling as a strategy to convert hazardous residue into low-carbon fuel, advocating integration of such benign hydrogen-generation routes into industrial design and policy to close material loops and enhance resilience.

铝渣用于制氢的增值提供了一个可持续的废物转化能源的途径。本研究考察了在40-70 °C条件下，铝渣在NaOH和KOH水溶液（0.25-1.0 M）中的析氢，测量了其作为时间的函数，并使用3D等高线映射来确定初始速率和累积产率。析氢量随碱浓度和温度的升高而升高；NaOH在较低的条件下产生更高的速率和体积，而KOH则表现出稳定的温度驱动增长。动力学研究表明，Avrami-Erofeyev模型与实验数据拟合最佳，线性良好（R2 = 0.95-0.99）。计算的反应阶数（n = 0.88-1.23）表明接近一级的行为符合成核-生长机制。Arrhenius分析得出活化能分别为63.07 kJ/mol（0.5 M NaOH）和73.62 kJ/mol（0.5 M KOH）。本研究将垃圾回收作为一种将有害残留物转化为低碳燃料的策略，倡导将这种良性的产氢路线纳入工业设计和政策中，以关闭材料循环并增强弹性。
