India has emerged as one of the global frontrunners in renewable energy (RE) deployment, driven by ambitious national targets, progressive policies, and rapid technological adoption. This study presents a comprehensive, data-driven assessment of India’s RE transition between 2010 and 2025, integrating secondary datasets from the Ministry of New and Renewable Energy, Central Electricity Authority, International Energy Agency, and National Institution for Transforming India Aayog. Using compound annual growth rate (CAGR), correlation, and trend analysis, the study evaluates the performance and inter-sectoral dynamics of solar, wind, hydro, and bioenergy segments. The findings reveal that India’s total installed renewable capacity increased from 17 GW in 2010–190 GW in 2025, with solar energy exhibiting the highest growth (CAGR ≈ 24.8%), followed by wind (≈ 10.3%). Regression analysis indicates a strong positive correlation (r = 0.91) between gross domestic product growth and renewable capacity expansion, emphasizing the sector’s economic significance. A novel contribution of this research lies in its multi-dimensional analytical framework, combining policy mapping, financial trends, and comparative benchmarking against Brazil, Russia, India, China, and South Africa nations to identify structural bottlenecks and feasible interventions. Key challenges such as grid integration, financing constraints, and intermittency are prioritized through a risk–impact matrix, while opportunities in green hydrogen, artificial intelligence/internet of things integration, offshore wind, and export potential are evaluated using a strengths, weaknesses, opportunities, and threats-based market feasibility model. The study concludes that achieving India’s 500 GW non-fossil target by 2030 requires annual investments exceeding USD 25–30 billion, regulatory harmonization, and digital optimization of energy systems. By synthesizing quantitative insights with policy analysis, this paper bridges the gap between descriptive reviews and empirical assessments, offering actionable guidance for policymakers, investors, and researchers engaged in India’s RE transition.

在雄心勃勃的国家目标、进步的政策和快速的技术采用的推动下，印度已成为可再生能源部署的全球领跑者之一。本研究综合了来自新能源和可再生能源部、中央电力局、国际能源署和印度国家转型机构的二手数据，对印度2010年至2025年的可再生能源转型进行了全面的数据驱动评估。利用复合年增长率（CAGR）、相关性和趋势分析，该研究评估了太阳能、风能、水电和生物能源领域的表现和部门间动态。研究结果显示，印度的可再生能源总装机容量从2010年的17 GW增加到2025年的190 GW，其中太阳能增长最快（复合年增长率≈24.8%），其次是风能（≈10.3%）。回归分析表明，国内生产总值增长与可再生能源产能扩张之间存在很强的正相关关系（r = 0.91），强调了该部门的经济意义。本研究的一个新颖贡献在于其多维分析框架，将政策映射、金融趋势以及与巴西、俄罗斯、印度、中国和南非等国的比较基准相结合，以确定结构性瓶颈和可行的干预措施。通过风险影响矩阵对电网整合、融资限制和间歇性等关键挑战进行优先排序，而绿色氢、人工智能/物联网整合、海上风电和出口潜力的机会则使用基于优势、劣势、机会和威胁的市场可行性模型进行评估。该研究得出的结论是，到2030年实现印度500吉瓦 非化石能源目标需要超过250亿至300亿美元的年度投资、监管协调和能源系统的数字化优化。通过将定量见解与政策分析相结合，本文弥合了描述性评估与实证评估之间的差距，为参与印度可再生能源转型的政策制定者、投资者和研究人员提供了可操作的指导。

This review explores the role of nanoadditives in improving the performance of biodiesel used in compression ignition (CI) engines. The central idea is that introducing nanoparticles (NPs) into biodiesel can enhance combustion, engine efficiency, and emission control without requiring significant engine modifications. The study focuses on widely used NPs such as Al₂O₃, TiO₂, CeO₂, Fe₃O₄, carbon nanotubes, and graphene oxide, examining their catalytic, thermal, and stabilization effects. Biodiesel blends are typically prepared from non-edible oils, purified, and infused with NPs through ultrasonication, sometimes with surfactants to maintain dispersion stability. Key fuel properties, including viscosity, density, calorific value, and oxidation stability, are assessed before engine testing. The review highlights how NPs improve fuel atomization, oxidation reactions, and heat transfer, leading to better ignition and more efficient combustion. Results from the literature show that nanoadditives enhance brake thermal efficiency, reduce fuel consumption, and significantly lower emissions of carbon monoxide, UHCs, and particulate matter. Oxygen-donating NPs like CeO₂ and TiO₂ promote complete combustion and soot reduction, while carbon-based NPs strengthen blend stability and atomization quality. The novelty of this review lies in its systematic analysis of the mechanisms, physicochemical improvements, and performance outcomes of nanoadditives in biodiesel. It also identifies key research gaps, including optimal NP dosage, long-term durability, and large-scale engine validation, offering valuable direction for sustainable CI engine development.

本文综述了纳米添加剂在改善压缩点火发动机生物柴油性能方面的作用。其核心思想是，将纳米颗粒（NPs）引入生物柴油可以增强燃烧、发动机效率和排放控制，而无需对发动机进行重大修改。该研究的重点是广泛使用的NPs，如Al₂O₃、TiO₂、CeO₂、Fe₃O₄、碳纳米管和氧化石墨烯，研究了它们的催化、热和稳定效果。生物柴油混合物通常由非食用油制备，经过纯化，并通过超声波注入NPs，有时加入表面活性剂以保持分散稳定性。关键的燃料特性，包括粘度、密度、热值和氧化稳定性，都是在发动机测试前评估的。该综述强调了NPs如何改善燃料雾化、氧化反应和传热，从而更好地点火和更有效地燃烧。研究结果表明，纳米添加剂提高了制动热效率，降低了燃料消耗，并显著降低了一氧化碳、uhc和颗粒物的排放。供氧NPs如CeO₂和TiO₂促进完全燃烧和减灰，而碳基NPs增强混合稳定性和雾化质量。本文的新颖之处在于系统地分析了纳米添加剂在生物柴油中的作用机理、理化改进和性能结果。它还确定了关键的研究差距，包括最佳NP用量、长期耐久性和大规模发动机验证，为可持续CI发动机的开发提供了有价值的方向。

Supercapacitors (SCs) are critical for sustainable energy storage due to their high power density and rapid charge-discharge capabilities, making them essential for renewable energy integration and electric vehicle applications. This study explores the solvothermal synthesis of spinel ferrites XFe₂O₄ (X = Mn, Co, Ni) as electrode materials for SCs. Structural characterization through X-ray diffraction confirmed phase-pure cubic structures with lattice parameters of 0.851 nm (MnFe₂O₄), 0.839 nm (CoFe₂O₄), and 0.834 nm (NiFe₂O₄), and crystallite sizes of 13.72 nm, 20.72 nm, and 11.86 nm, respectively. Scanning electron microscopy revealed agglomerated nanoparticles for MnFe₂O₄ and CoFe₂O₄, and densely packed aggregates for NiFe₂O₄. Fourier-transform infrared spectroscopy identified a conductive carbonaceous layer from residual ethylene glycol, while UV-Vis spectroscopy determined bandgaps of 2.7 eV (CoFe₂O₄), 3.12 eV (MnFe₂O₄), and 3.7 eV (NiFe₂O₄). Electrochemical assessments using cyclic voltammetry, galvanostatic charge-discharge, and electrochemical impedance spectroscopy showed CoFe₂O₄ achieving a specific capacitance of 1518 F/g at 0.5 A/g with 99.9% retention after 5000 cycles, outperforming MnFe₂O₄ and NiFe₂O₄. Symmetric devices based on CoFe₂O₄ delivered a specific capacitance of 668 F/g at 1 A/g, an energy density of 33.38 Wh/kg, and a power density of 150 W/kg. These results position CoFe₂O₄ as a promising material for next-generation SCs, advancing energy storage for sustainable systems.

超级电容器（SCs）由于其高功率密度和快速充放电能力，对可持续能源存储至关重要，使其成为可再生能源集成和电动汽车应用的必要条件。本研究探讨了溶剂热合成尖晶石铁氧体XFe2O4 （X = Mn, Co, Ni）作为SCs电极材料的方法。通过x射线衍射表征，确定了相纯立方结构，晶格参数分别为0.851 nm （MnFe2O4）、0.839 nm （CoFe2O4）和0.834 nm （NiFe2O₄），晶粒尺寸分别为13.72 nm、20.72 nm和11.86 nm。扫描电镜显示，MnFe2O4和CoFe2O4为球状纳米颗粒，而NiFe2O4为密集堆积的团聚体。傅里叶变换红外光谱在残余乙二醇中发现了导电碳质层，紫外可见光谱测定了2.7 eV （CoFe2O4）、3.12 eV （MnFe2O4）和3.7 eV （NiFe2O4）的带隙。利用循环伏安法、恒流充放电法和电化学阻抗谱进行的电化学评价表明，在0.5 a /g下，CoFe2O4的比电容达到1518 F/g，循环5000次后保持率达到99.9%，优于MnFe2O4和NiFe2O4。基于CoFe2O4的对称器件在1 a /g时的比电容为668 F/g，能量密度为33.38 Wh/kg，功率密度为150 W/kg。这些结果将CoFe2O4定位为下一代超导材料的有前途的材料，推进可持续系统的能量存储。
