The escalating challenges of non-agricultural accumulation and global energy demands underscore the need for innovative waste-to-energy solutions that mitigate environmental impacts and address food-fuel conflicts. This review advances the field by exploring non-agricultural biomass- municipal solid waste, forestry residues, industrial organic waste, algal biomass, textile waste, and invasive plant species as sustainable feedstocks for bioenergy production, supporting waste management, energy security, and circular bioeconomies. Their physicochemical properties, conversion technologies (pyrolysis, gasification, anaerobic digestion, and hydrothermal liquefaction), and challenges, like feedstock heterogeneity and high moisture content, are evaluated. Advanced pretreatments enhance conversion efficiencies, while technologies yield significant environmental benefits, including methane emission reductions and carbon sequestration. Socio-economic advantages include job creation, reduced fossil fuel dependency, and alignment with sustainable development goals for clean energy and sustainable cities. To address scalability gaps, this review introduces three novel contributions: (1) an AI-integrated urban biorefinery framework leveraging plasma gasification and AI-driven sorting to optimize heterogeneous feedstocks; (2) valorization strategies for understudied feedstocks like invasive species, enhancing bioenergy outputs through hybrid systems; and (3) scalable pathways tailored to urban and rural waste systems. Policy incentives, such as carbon taxes, are critical for economic viability, enabling these strategies to support global net-zero emissions goals by 2050 through sustainable waste-to-energy systems.

随着非农业积累和全球能源需求的挑战不断升级，需要创新的废物转化为能源的解决方案，以减轻对环境的影响并解决粮食-燃料冲突。本文综述了非农业生物质——城市固体废弃物、林业废弃物、工业有机废弃物、藻类生物质、纺织废弃物和入侵植物物种——作为生物能源生产的可持续原料，为废物管理、能源安全和循环生物经济提供支持。评估了它们的物理化学性质、转化技术（热解、气化、厌氧消化和水热液化）以及挑战，如原料异质性和高水分含量。先进的预处理提高了转化效率，而技术产生了显著的环境效益，包括减少甲烷排放和碳固存。社会经济优势包括创造就业机会，减少对化石燃料的依赖，并与清洁能源和可持续城市的可持续发展目标保持一致。为了解决可扩展性的差距，本文介绍了三个新的贡献：(1)利用等离子气化和人工智能驱动的分选来优化异质原料的人工智能集成的城市生物炼制框架；(2)对入侵物种等未充分研究的原料的增值策略，通过杂交系统提高生物能源产量；(3)针对城市和农村垃圾处理系统量身定制的可扩展路径。碳税等政策激励措施对经济可行性至关重要，使这些战略能够通过可持续的废物转化为能源系统，支持到2050年实现全球净零排放目标。

The inexplicable energy sink: Addressing efficiency and sustainability gaps in india’s coal-to-power value chain 令人费解的能源消耗：解决印度煤制电价值链的效率和可持续性差距

Despite major policy reforms in India’s coal and power sectors — including third-party sampling at both dispatch and receipt points and the shift from as fired to as received GCV measurement — large discrepancies in gross calorific value (GCV) between mine and plant continue to be reported. This paradox is striking, as both sectors now follow identical, standardized procedures, yet even pithead plants located just kilometres from mines show substantial GCV losses. This study applies statistical analysis and national rainfall data to test whether these reported losses align with sectoral norms and global research benchmarks. The findings reveal that observed transit-related (GCV) losses often exceed physically plausible limits, pointing to systemic inconsistencies, sampling deviations, or procedural flaws. Understanding the nature and extent of these gaps is vital to reduce unnecessary coal procurement, lower electricity tariffs, and improve sustainability across India’s coal-to-power value chain.

尽管印度煤炭和电力行业进行了重大政策改革——包括在发送点和接收点进行第三方抽样，以及从“燃烧”到“接收”的GCV测量方法的转变——但仍有报道称，煤矿和电厂之间的总热值（GCV）存在巨大差异。这一矛盾是惊人的，因为这两个部门现在都遵循相同的标准化程序，然而，即使距离矿山仅几公里的坑口工厂也显示出大量的GCV损失。本研究采用统计分析和国家降雨数据来检验这些报告的损失是否符合部门规范和全球研究基准。研究结果表明，观测到的凌日相关（GCV）损失通常超过物理上合理的极限，这表明系统不一致、抽样偏差或程序缺陷。了解这些差距的性质和程度对于减少不必要的煤炭采购、降低电价以及提高印度煤电价值链的可持续性至关重要。

Perovskite solar cells (PSCs) combine outstanding optoelectronic properties with low fabrication cost, with methylammonium lead bromide (CH₃NH₃PbBr₃) offering superior thermal stability, a 2.2 eV band gap, and a high absorption coefficient (10⁵–10⁶ cm⁻¹). This study employs SCAPS-1D simulations under AM1.5 G illumination to analyze an FTO/BaTiO₃/CH₃NH₃PbBr₃/Cu₂O/Ni device, achieving a 17.00% power conversion efficiency (PCE), 1.8515 V open-circuit voltage (V_OC), 9.923 mA cm⁻² short-circuit current density (J_SC), and 92.51% fill factor (FF), enabled by optimal band alignment and reduced recombination. Quantum efficiency (QE) reached ∼100% in the visible range, confirming strong light-harvesting. Parametric optimization identified optimal operation at 300 K with a shunt resistance of 10⁵ Ω·cm². Machine learning (ML) models; artificial neural networks (ANN) and k-nearest neighbors (k-NN) were applied to assess the influence of material properties on device performance. The results offer guidelines for fabricating cost-effective, high-performance Pb–based PSCs and reinforce CH₃NH₃PbBr₃’s role as a benchmark absorber for device optimization.

Perovskite, oxide, organic, and dye-sensitised solar cells are studied from 2015 to 2025, and their current standing and future Mott-Schottky (MS) analysis in photovoltaic (PV) research are highlighted in this review. The incorporation of MS characterisation methodology with solar cell capacitance simulator one dimension (SCAPS-1D) simulations, ab-initio calculations, impedance spectroscopy, and nascent data-driven models is addressed. The MS approach will always be at the forefront in the extraction of the flat band potential, doping concentration, depletion region width, and built-in potential. This is the link between the energetics of the semiconductors and the charge transport of the solar cells and other PV. With MS-validated doping profile optimisation, interface engineering achieves (37.66%) power conversion efficiencies, 1.52 V (open-circuit voltages) and fill factors above (87%). Unfortunately, there are limitations of the frequency-dependent capacitance, parasitic elements, trap states, and non-ideal depletion layer of some architectures, like organic and hybrid ones. The MS and simulations to be used together, and machine learning adoption and analytical models to improve the electronic characterisation, have the potential to resolve the problems. This study offers a critical evaluation of current methods and inherent constraints in MS analysis, offering a strategic framework for the systematic design of efficient, durable, and sustainable solar technologies.

本文综述了钙钛矿、氧化物、有机和染料敏化太阳能电池在2015年至2025年的研究，并重点介绍了它们在光伏（PV）研究中的现状和未来的莫特-肖特基（Mott-Schottky）分析。将质谱表征方法与太阳能电池电容模拟器一维（SCAPS-1D）模拟、从头计算、阻抗谱和新生数据驱动模型相结合。质谱法在提取平带电位、掺杂浓度、耗尽区宽度和内置电位方面始终处于领先地位。这是半导体的能量学与太阳能电池和其他PV的电荷输运之间的联系。通过ms验证的掺杂谱优化，界面工程实现了（37.66%）的功率转换效率，1.52 V（开路电压）和（87%）以上的填充因子。不幸的是，在某些结构（如有机和混合结构）中，存在频率相关电容、寄生元件、陷阱状态和非理想耗尽层的局限性。将质谱和模拟结合使用，采用机器学习和分析模型来改进电子表征，有可能解决这些问题。本研究对质谱分析中的现有方法和固有限制进行了批判性评估，为高效、耐用和可持续太阳能技术的系统设计提供了战略框架。

Alkali-promoted calcium-based heat carriers for solar-driven thermochemical energy storage 用于太阳能热化学储能的碱促进钙基热载体

Calcium looping (CaL) process can convert solar energy into chemical energy in a concentrating solar power system, which will be further converted to heat energy to generate electricity. The calcium-based heat carrier in the CaL is considered to be a highly prospective future medium for thermochemical energy storage (TCES) because of its excellent energy storage performance, low input cost, and high cycle operating temperature. However, sintering occurs when the heat carriers are cycled at elevated temperatures, leading to a substantial reduction in their energy storage capacity and hindering their practical applications. In this work, the sintering problem was highly mitigated, and the TCES capacity of calcium-based heat carriers was obviously promoted by doping with alkali meal salts, which are usually considered adverse for the carbonation and calcination reaction of the heat carriers. Based on the modification experiments, it can be reasonably inferred that during the high-temperature operation process, part of the alkali metal salts sublimates and escapes to provide abundant porosity for calcium-based heat carriers. Simultaneously, the other part covers the surface of the calcium particles in a molten state to maintain the stability of the pore skeleton, which greatly enhances the energy storage performance of the heat carriers. As a result, "0.5 K₂CO₃/CaO" showed the best energy storage performance improvement. During high-temperature cycling, the performance of the heat carrier initially increased gradually, followed by an extremely slow decline. Even after 20 cycles, the energy storage capacity still remained at a high level of 1977.23 kJ/kg. This final energy storage capacity was 2.85 times higher than that of unmodified CaO. The microstructural characterizations showed that the "0.5 K₂CO₃/CaO" obtained richer small particles and pore structure after cycles, benefiting from the doping of K₂CO₃ and providing good pore channels for carbonation to inhibit sintering. Therefore, CaO-based heat carriers promoted by alkali metal salts hold significant potential for advancing the application of the TCES system in concentrated solar power plants.

在聚光太阳能发电系统中，钙环（CaL）过程将太阳能转化为化学能，化学能再转化为热能发电。钙基热载体由于其优异的储能性能、低投入成本和高循环工作温度，被认为是一种极具发展前景的热化学储能（TCES）介质。然而，当热载体在高温下循环时，会发生烧结，导致其能量储存能力大幅降低，阻碍了其实际应用。在本研究中，钙基热载体的烧结问题得到了很大的缓解，碱粕盐的掺入明显提高了钙基热载体的TCES容量，而碱粕盐通常被认为不利于热载体的碳化和煅烧反应。通过改性实验可以合理推断，在高温操作过程中，部分碱金属盐升华逸出，为钙基热载体提供了丰富的孔隙。同时，另一部分覆盖在处于熔融状态的钙颗粒表面，保持孔隙骨架的稳定性，大大增强了热载体的储能性能。结果表明，“0.5 K2CO3/CaO”的储能性能改善效果最好。在高温循环过程中，热载体的性能在开始时逐渐提高，随后下降极为缓慢。即使经过20次循环，储能容量仍保持在1977.23 kJ/kg的高水平。最终储能容量是未改性CaO的2.85倍。微观结构表征表明，循环后“0.5 K2CO3/CaO”获得了更丰富的小颗粒和孔隙结构，这得益于K2CO3的掺杂，为碳化提供了良好的孔隙通道，从而抑制烧结。因此，碱金属盐促进的cao基热载体对推进TCES系统在聚光太阳能电站中的应用具有重要的潜力。

Millions of households in developing countries burn dung cakes made from common farmyard manure to fulfil their household energy needs. Localised studies investigate dung cake use and its impact. However, a comprehensive review of the social practice of dung cake use as a household fuel and its impact are not available. Our exploratory systematic review on the social practice of burning dung as fuel and its impacts, reveals that due to their higher emissions than fuelwood and crop residue, dung cakes are primarily situated at the bottom of the energy ladder and are used as a niche fuel by energy-poor households. This review underscores the notable absence of knowledge about the social practice of dung cake as a fuel. Our study on the practice of burning dung cake as household fuel, dung cake users, their communities, and the context they are using dung cake helps to identify policy strategies as part of the clean energy transition, to benefit communities and improve global clean cooking practices. We highlight the importance of identifying cost-effective behavioural changes and context-specific solutions to accelerate the clean cooking transition in these communities.

在发展中国家，数以百万计的家庭燃烧由普通农家肥制成的粪饼来满足他们的家庭能源需求。局部研究调查粪饼的使用及其影响。然而，对粪饼作为家庭燃料的社会实践及其影响的全面审查尚未得到。我们对牛粪作为燃料的社会实践及其影响进行了探索性的系统回顾，结果表明，由于牛粪饼的排放高于薪木和农作物秸秆，因此牛粪饼主要处于能源阶梯的底部，被能源贫乏的家庭用作利基燃料。这篇综述强调了关于粪饼作为燃料的社会实践的显著缺乏知识。我们对牛粪饼作为家庭燃料的燃烧实践、牛粪饼使用者、他们的社区以及他们使用牛粪饼的背景的研究有助于确定作为清洁能源转型一部分的政策战略，从而使社区受益并改善全球清洁烹饪实践。我们强调确定具有成本效益的行为改变和因地制宜的解决方案的重要性，以加速这些社区向清洁烹饪的过渡。

As a critical component in electric vehicles and energy storage systems, the dynamic relationship between state of charge (SOC) and thermal runaway (TR) propagation in LiFePO₄ batteries remains insufficiently understood. To address the critical limitation of existing TR testing methods in achieving synchronized multiparameter acquisition, this study developed an integrated multi-physics monitoring platform enabling spatiotemporal correlation analysis across the entire TR chain-from triggered initiation, heat/smoke release, gas speciation, 2 dimension temperature field reconstruction (infrared thermography), to TR process visualization. Systematic investigation of 18650-type LiFePO₄ cells across SOC gradients revealed distinct failure modes: 100% SOC cells exhibited predominant heat-driven failure with total heat release reaching 5.95 MJ/m² (a 5-fold increase versus 50% SOC cells), while 50% SOC cells demonstrated prioritized smoke aerosol release (520% higher particulate density than 100% SOC) with delayed combustible gas generation. This platform overcomes single-parameter detection constraints in conventional methods, providing multiscale experimental evidence to guide SOC-stratified safety protocols and phase-change thermal barrier material optimization for lithium-ion battery systems.

作为电动汽车和储能系统的关键部件，LiFePO4电池的荷电状态（SOC）与热失控（TR）传播之间的动态关系尚不清楚。为了解决现有TR测试方法在实现同步多参数采集方面的关键限制，本研究开发了一个集成的多物理场监测平台，可以在整个TR链中进行时空相关性分析-从触发起始，热/烟雾释放，气体形态，二维温度场重建（红外热成像）到TR过程可视化。对18650型LiFePO4电池在SOC梯度上的系统研究揭示了不同的失效模式：100% SOC电池表现出主要的热驱动失效，总热释放达到5.95 MJ/m²（比50% SOC电池增加了5倍），而50% SOC电池表现出优先的烟雾气溶胶释放（颗粒密度比100% SOC高520%），可燃气体的产生延迟。该平台克服了传统方法中单参数检测的限制，为指导锂离子电池系统的soc分层安全协议和相变热障材料优化提供了多尺度实验证据。

The pursuit of sustainable energy solutions on a global scale has heightened the exploration of alternative fuels, aimed at reducing greenhouse gas emissions and lessening dependence on fossil fuels. Hydrogen, known for its high energy content and environmentally friendly combustion properties, has emerged as a promising contender for addressing these challenges. When used as a fuel source, hydrogen offers the potential to achieve zero carbon emissions, positioning it as a pivotal element in the shift towards a sustainable energy landscape. Incorporating hydrogen into internal combustion engines (ICEs) has opened avenues for advancing sophisticated combustion modes. These novel modes optimize hydrogen utilization and improve engine efficiency, performance, and ecological sustainability. This article delves into various cutting-edge combustion technologies that harness hydrogen as a primary fuel source, including conventional modes such as dual fuel and advanced modes such as reactivity controlled compression ignition (RCCI), homogeneous charge compression ignition (HCCI), premixed charge compression ignition (PCCI), and gasoline compression ignition (GCI). These advanced modes represent significant progress in the development of hydrogen-fueled engine technology. Each mode offers unique advantages and faces specific challenges. This review aims to provide a comprehensive overview of the current state of these technologies, examining their benefits, limitations, and future research directions necessary to realize the full potential of hydrogen in advanced combustion engines.

Fuel cell electric vehicles (FCEVs) provide a viable answer to transportation issues caused by fossil fuel limitations and environmental concerns. This review presents a thorough evaluation of the most recent advances in FCEV durability research. It addresses 4 major topics: component upgrades, technical control techniques, test optimization, and durability prediction. Upgrades to components include improved catalysts, bipolar plates, gas diffusion layers, proton exchange membranes, and plant balancing. Technical control solutions include power, energy, temperature, ventilation, and control management. Stress acceleration and cold start tests are examples of test optimization, whereas durability prediction requires parameter selection, real-time monitoring, dynamic modeling, and lifespan prediction. This review also makes some novel recommendations targeted at improving the endurance of FCEVs. These include measures for raising public awareness, lowering prices while increasing performance, improving subsystems for greater durability, updating health diagnostics to prevent performance deterioration, and implementing supporting regulations to encourage industry upgrading. These findings are expected to accelerate the adoption of FCEVs and the transition to a more sustainable transportation system.

Metal oxide nanofilms have drawn interest as essential components for next-generation supercapacitors due to growing demands for effective energy storage devices. Electrodes were fabricated by thermally depositing pure and Al-doped NiO onto graphene oxide (GO), followed by drop-casting the NiO-coated GO onto a grafoil sheet with improved electrochemical properties. The resulting composite electrodes were characterized using X-ray diffraction, Fourier transform infrared spectroscopy, Raman spectroscopy, and Scanning Electron Microscopy (SEM), confirming the formation of nanoscale NiO coatings and the presence of Ni–O and GO-related vibrational modes. Electrochemical evaluation in 2 M and 3 M KOH electrolytes revealed highly pseudocapacitive behavior. Specific capacitance values obtained from cyclic voltammetry at a scan rate of 10 mV/s were 172, 137.53, and 89.92 F/g for undoped, 2% Al-doped, and 4% Al-doped NiO electrodes, respectively, in 2 M KOH; and 181.25, 157.05, and 93.75 F/g in 3 M KOH. All electrodes demonstrated excellent cycling stability, retaining their performance after 100 charge–discharge cycles at a scan rate of 100 mV/s. These results suggest that NiO/GO-coated grafoil electrodes, particularly undoped NiO, are promising candidates for high-performance supercapacitor applications.

由于对有效储能装置的需求日益增长，金属氧化物纳米膜作为下一代超级电容器的重要组成部分引起了人们的兴趣。电极是通过在氧化石墨烯（GO）上热沉积纯的和掺杂al的NiO来制备的，然后将NiO涂层的GO滴铸到具有改善电化学性能的接枝油片上。利用x射线衍射、傅里叶变换红外光谱、拉曼光谱和扫描电子显微镜（SEM）对复合电极进行了表征，证实了纳米级NiO涂层的形成以及Ni-O和go相关振动模式的存在。2 M和3 M KOH电解质的电化学评价显示出高度的假电容行为。在2 M KOH溶液中，在扫描速率为10 mV/s的循环伏安法下，未掺杂、掺2% al和掺4% al的NiO电极的比电容值分别为172、137.53和89.92 F/g；3 M KOH分别为181.25、157.05、93.75 F/g。所有电极都表现出优异的循环稳定性，在100次充放电循环后，以100 mV/s的扫描速率保持其性能。这些结果表明，NiO/ go涂层接枝油电极，特别是未掺杂的NiO，是高性能超级电容器应用的有希望的候选者。
