This study evaluates the integration of wind energy into greenhouse agriculture in the Safi region, a major agricultural area in Morocco. As part of cleaner energy systems, five wind turbines were analyzed to determine their performance. After performing a statistical analysis using the Weibull distribution with two parameters, the results showed that the VESTAS V82–0.9/1.65MW – 70 m turbine was the most efficient. It achieved a capacity factor of 41.72 %, an annual energy production of 3 326.17 MWh, and the ability to supply electricity to 6 960 m² of agricultural greenhouses. Environmental benefits include a significant reduction in carbon dioxide emissions. Economically, the results vary, with a payback period of <5 years for the VESTAS turbine but a longer period of 10.49 years for the Norwin – 30 m turbine. To address fluctuations in wind energy caused by daily wind speed variations, this innovative study explores combining wind power with hydrogen production. The results indicate that the Safi region has the potential to produce between 25 188.76 kg and 44 875.25 kg of hydrogen annually, depending on the turbine used. Additionally, this approach could reduce annual CO₂ emissions by up to 2 606 609 kg. These findings highlight a promising innovation in cleaner energy systems to enhance agricultural sustainability through renewable energy solutions.

本研究评估了风能与摩洛哥主要农业区萨菲地区温室农业的结合情况。作为清洁能源系统的一部分，对五台风力涡轮机进行了分析，以确定其性能。在使用两个参数的 Weibull 分布进行统计分析后，结果显示 VESTAS V82-0.9/1.65MW - 70 米风机的效率最高。它的容量系数为 41.72%，年发电量为 3 326.17 兆瓦时，能够为 6 960 平方米的农业温室供电。环境效益包括二氧化碳排放量大幅减少。在经济上，结果各不相同，VESTAS 风机的投资回收期为 5 年，而 Norwin - 30 米风机的投资回收期则长达 10.49 年。为了解决每日风速变化造成的风能波动问题，这项创新研究探索了风力发电与氢气生产的结合。结果表明，根据所使用的涡轮机，萨菲地区每年可生产 25 188.76 千克至 44 875.25 千克氢气。此外，这种方法每年还可减少高达 2 606 609 千克的二氧化碳排放量。这些发现凸显了清洁能源系统的创新前景，可通过可再生能源解决方案提高农业的可持续性。

The integration of innovative systems as an effective waste-heat recovery strategy for the utilization of low-temperature heat sources is receiving increased attention as an alternative sustainable approach towards reducing fossil fuel combustion and emission pollution. Heat sink devices are identified as the primary sources of waste-heat, hence, the effective utilization of the waste-heat through systems integration are exploited. In this study, exergetic and exergoeconomic based parametric analysis is performed on combined recompression supercritical carbon dioxide Brayton - organic Rankine cycle with integrated LiBr/H₂O absorption refrigeration cycle and thermoelectric generator units. The proposed system aims to maximize low-grade waste heat conversion to electricity through sustainable system integration. Thermodynamic and exergoeconomic analysis was performed for both the base- and enhanced-systems, and parametric investigation carried out to predict the effect of temperature, pressure and mass flow rate variation on system's performance parameters. Results obtained indicate that the enhanced-system has a net power output of +48.58 % higher than the base-system, with 1.3 %, 11.9 %, and 14.7 % contributed by the thermoelectric generators (TEGI, TEGII, and TEGIII, respectively). Similarly, the enhanced-system reveals +22.55 % and +28.19 % better first- and second-law efficiencies than the base-system. The heat exchanger, absorption refrigeration cycle generator and solution heat exchanger are the major components with the highest value of exergy destruction with 15.23 %, 12.99 %, and 11.97 % contribution to the total exergy destroyed in the system. Therefore, the same components are considered priority for system improvement efforts as suggested by the values of improvement potential, fuel depletion ratio, Irreversibility and

The present study numerically involves the feasibility analysis of environment, economic and energy of 1MWp photovoltaic (PV) system under Iraq climatic condition. The photovoltaic model is based on the monocrystal silicon solar panels with suitable inverters and other accessories. Real metrological data from NREL measurements for 21 different sites in Iraq are used to determine the best site for installing photovoltaic power plant. A sensitivity model is also developed to investigate the climate conditions e.g., Global Horizontal Irradiance (GHI), ambient temperature, altitude, absolute air mass on the capacity factors, yield factors and cost of energy for different 21 sites. Results indicated that photovoltaic power plant can be installed in different locations in Iraq due to their 3-E performances although there are some variations in these performances due to the variation in the geographical nature and metrological data. The 3-E performances outcomes indicated that the avoided of CO₂ emission ranged between 2.17tCO2/ kWp and 2.55tCO2/ kWp, the levelized cost of energy ranged between 0.093USD and 0.079USD and the yield energy ranged between 1514kWh/kWp and 1745kWh/kWp, respectively. The findings display that the optimum performances are achieved in Al-Rutba city and the minimum performances are recorded in Erbil city. The other monthly energy performance ensure the yearly performance. There are similarities in the technical, economic and environment performance for some cities due to the similarities in the climatic conditions. The outcomes display that there is a direct relationship between global horizontal irradiance and technical and economic results. Other climate conditions have an effect on the results but these effects are low as compared to global horizontal irradiance. The rising in degradation rate, inflation rate and PV module price leads to rise in energy cost of plant, while the increase in the power of plant has no effect on energy cost. The conclusions display that all locations are workable for installing PV system, but Al-Rutba city is the best between them.

本文对伊拉克气候条件下1MWp光伏发电系统的环境、经济和能源可行性进行了数值分析。光伏模型是基于单晶硅太阳能电池板与合适的逆变器和其他配件。来自伊拉克21个不同地点的NREL测量的真实计量数据用于确定安装光伏发电厂的最佳地点。此外，还建立了敏感性模型，研究了全球水平辐照度（GHI）、环境温度、海拔高度、绝对空气质量等气候条件对21个站点的容量因子、产量因子和能源成本的影响。结果表明，尽管由于地理性质和气象数据的差异，光伏电站的3-E性能存在一定差异，但由于光伏电站的3-E性能可以在伊拉克的不同地点安装。3-E性能结果表明，可避免的CO2排放范围在2.17 ~ 2.55tCO2/ kWp之间，净能成本范围在0.093 ~ 0.079美元之间，发电量范围在1514 ~ 1745kWh/kWp之间。结果表明，Al-Rutba市取得了最佳绩效，Erbil市取得了最低绩效。其他月度能源绩效确保年度绩效。由于气候条件的相似性，一些城市在技术、经济和环境绩效方面存在相似之处。结果表明，全球水平辐照度与技术经济效益之间存在直接关系。其他气候条件对结果也有影响，但与全球水平辐照度相比，这些影响很小。降解率、通货膨胀率和光伏组件价格的上升导致电站能源成本上升，而电站功率的增加对能源成本没有影响。结论表明，所有地点均可安装光伏系统，但Al-Rutba市是其中最好的。

Reducing and reusing waste heat is crucial to increasing the economic benefits and energy efficiency of industrial processes. Furthermore, combating climate change relies heavily on recovering heat that would otherwise be squandered. With a growing population comes a greater need for clean drinking water. Single mixed refrigerant (SMR) cycle, one of the most practical refrigerating technologies for natural gas liquefaction, rejects a great deal of heat energy in the intercoolers between multistage compression that may be used as the primary heat source for a low-temperature multi-effect desalination plant. This research suggests combining a natural gas liquefaction system with a Liquid Vapor Ejector (LVE) and a Single Mixed Refrigerant (SMR) system, all of which use multi-effect distillation with thermal vapor compression (MED-TVC). The design code SMR-MED integrated system is developed using an in-house robust algorithm in Python. In this setting, the fact that the MED-TVC system can use waste heat from a single mixed refrigerant natural gas liquefaction facility highlights its flexibility. An energy and exergy analysis are performed to determine the feasibility of the proposed system. The design code has been validated against the existing literature. The parametric analysis has been done by changing three independent parameters: namely, refrigerant mass flow rate (10 kg/s to 30 kg/s), water mass flow rate at the intercooler (10kg/s to 40kg/s), and water inlet temperature at the intercooler (17 °C to 35 °C), as, these parameters affects both the LNG production SMR cycle as well as Distillate and Brine production in the MED-TVC system. The results suggest that increasing refrigerant flow increases the cooling effect by 299.68 %, thus producing 289.90 % more LNG; however, exponentially declines distillate by 74.22 %, thus limiting maximum refrigerant flow. Increasing the water mass flow rate improves the distillate production and Gained output ratio (GOR) by 676.07 % and 676.92 %, respectively; conversely, it reduces brine production by 72.97 %. In contrast, increasing water inlet temperature reduces distillate generation and overall system performance. The study results can be used to improve existing system performance and design more sustainable waste heat recovery systems.

减少和再利用废热对提高工业过程的经济效益和能源效率至关重要。此外，应对气候变化在很大程度上依赖于回收原本会被浪费的热量。随着人口的增长，对清洁饮用水的需求也越来越大。单混合制冷剂（SMR）循环是天然气液化中最实用的制冷技术之一，它在多级压缩之间的中间冷却器中排除了大量的热能，这些热能可作为低温多效海水淡化厂的主要热源。本研究建议将天然气液化系统与液体蒸汽喷射器（LVE）和单一混合制冷剂（SMR）系统相结合，这两种系统都采用多效蒸馏与热蒸汽压缩（MED-TVC）。设计代码SMR-MED集成系统在Python中使用内部鲁棒算法开发。在这种情况下，MED-TVC系统可以利用单一混合制冷剂天然气液化设施的废热，这一事实凸显了其灵活性。进行了能量和火用分析，以确定所提出系统的可行性。设计代码已根据现有文献进行了验证。参数分析是通过改变三个独立的参数来完成的：即制冷剂质量流量（10kg/s至30 kg/s）、中冷器的水质量流量（10kg/s至40kg/s）和中冷器的进水温度（17℃至35℃），因为这些参数既影响LNG生产SMR周期，也影响MED-TVC系统的馏分油和卤水生产。结果表明：增加制冷剂流量可使冷却效果提高299.68%，LNG产量增加289.90%；然而，指数下降馏分74.22%，从而限制了最大制冷剂流量。提高水质量流量可使馏分产量提高676.07%，收率提高676.92%；相反，它减少了72.97%的卤水产量。相反，增加进水温度会降低馏分产生和整体系统性能。研究结果可用于改进现有系统性能和设计更具可持续性的余热回收系统。

The rapid accumulation of end-of-life tires, driven by global vehicle use, presents severe environmental challenges. Each year, approximately 3 billion tires are produced globally, with 800 million reaching end-of-life, of which 41% are landfilled without material or energy recovery. Pyrolysis has emerged as a sustainable solution, converting waste tires into valuable by-products, including pyrolysis oil, gas, and recovered carbon black (rCB). This bibliometric review analyzes 1,431 publications (2000–2024) sourced from Scopus to map research trends, advancements, and gaps in tire pyrolysis. Three primary research hotspots are identified: (1) co-pyrolysis, emphasizing feedstock optimization and microwave-assisted methods to enhance efficiency and product quality, (2) pyrolysis oil, addressing challenges in upgrading for industrial use, and (3) recovered carbon black (rCB), focusing on advanced demineralization and activation techniques to improve its properties. Key challenges identified include feedstock variability, catalytic system optimization, and process scalability. This review provides insights and a strategic framework for advancing tire pyrolysis, fostering sustainable practices, and driving innovation across energy, materials, and environmental applications.

Dynamic energy tariffs in combination with energy storage systems (ESS) and renewable energy sources (RES) offer manufacturers new opportunities to optimize their energy consumption. Flexible production planning empowers decision-makers not only to minimize makespan, but also to reduce energy costs and emissions. However, flexible production planning is a major challenge due to the fact that scheduling decisions affect energy demand, whose costs and emissions depend on energy procurement decisions.

动态能源关税与储能系统（ESS）和可再生能源（RES）相结合，为制造商提供了优化能源消耗的新机会。灵活的生产计划不仅使决策者能够最大限度地缩短完工时间，而且还能降低能源成本和排放。然而，灵活的生产计划是一个主要挑战，因为调度决策会影响能源需求，而能源需求的成本和排放取决于能源采购决策。在运筹学中，绿色柔性作业车间调度问题（FJSP）解决了结合资源、环境和经济目标的生产计划决策。能源采购问题（EPP）旨在有效地获取能源资源。在文献中，现有的能源感知调度方法忽略了从不确定的动态能源市场、RES和ESS中获取能源。为了缩小这一研究差距，我们提出了一种基于模因非支配排序遗传算法（NSGA-III）和线性规划的两级方法，其目标是将动态能源价格和排放、RES和ESS结合起来，使计划的完工时间、能源成本和排放最小化。我们在计算实验中使用文献中的FJSP基准实例来评估该方法，作为具有真实能源市场数据的滚动地平线方法的一部分。我们通过提出估计的帕累托前沿来研究RES和ESS的影响，显示了能源成本和碳排放的潜在节约。

This study explores a sustainable solution to address water scarcity in rural coastal areas. Using field data and simulations, the production cost of water was determined for a small-scale desalination plant designed and built by the University of Concepción. The plant employs nanofiltration technology and is powered by a hybrid system that includes solar panels, batteries, and a backup diesel generator, reducing reliance on non-renewable resources. This plant has been operational in the Cobquecura area of the Ñuble Region, Chile, since 2022. The methodology involved identifying an optimal operating profile, validated via simulations with Homer-Pro software, and calculating both the potable and irrigation water production and the average production cost of water. The results indicate an average water production cost of USD 3.19/m³, with 56 % of the cost attributed to the initial investment, 26 % to operational expenses, and 18 % to planned component replacements. This cost is significantly lower than the estimated cost of water delivered by tanker trucks, which can reach up to USD 24/m³ in the region. Additionally, tanker trucks are limited to operating under favorable weather conditions due to challenges posed by rural road infrastructure. This analysis highlights the technical and economic viability of integrating advanced desalination technologies with renewable energies, demonstrating their potential to address one of the most pressing environmental challenges in ensuring a reliable water supply for communities in remote areas. These findings offer a sustainable and innovative pathway to improve water scarcity and confirm the cost-effective application of renewable-energy-powered desalination solutions.

本研究探讨了解决沿海农村缺水问题的可持续解决方案。利用实地数据和模拟，确定了Concepción大学设计和建造的小型海水淡化厂的水生产成本。该工厂采用纳滤技术，并由包括太阳能电池板、电池和备用柴油发电机在内的混合系统供电，减少了对不可再生资源的依赖。该工厂自2022年以来一直在智利Ñuble地区的Cobquecura地区运营。该方法包括确定最佳操作剖面，通过Homer-Pro软件进行模拟验证，并计算饮用水和灌溉水产量以及水的平均生产成本。结果表明，平均产水成本为3.19美元/立方米，其中56%的成本归因于初始投资，26%的成本归因于运营费用，18%的成本归因于计划中的组件更换。这一成本明显低于油罐车输送水的估计成本，在该地区，油罐车输送水的成本最高可达24美元/立方米。此外，由于农村道路基础设施的挑战，油罐车只能在有利的天气条件下运行。这一分析强调了将先进的海水淡化技术与可再生能源相结合的技术和经济可行性，显示了它们在解决确保偏远地区社区可靠供水这一最紧迫的环境挑战方面的潜力。这些发现为改善水资源短缺提供了可持续和创新的途径，并确认了可再生能源驱动的海水淡化解决方案的成本效益应用。

The increasing global energy consumption and carbon dioxide emissions from fossil fuel burning pose a significant issue in the modern era. Alternative energy sources are now necessary due to depletion of fuels derived from petroleum sources and their associated environmental impact. Fruit wastes can be utilized to make bioethanol which have the potential to decrease pollution and carbon dioxide emissions. In this study, bioethanol from a mixture of fruit wastes was produced through fermentation and distillation process. The physical pre-treatment of fruit wastes produced a juice with an average total soluble solids content of 9.7 ± 0.06 °Brix. Fruit wastes juice was enriched with sorghum and millet flour to provide additional fermentable sugars. Fruit wastes juice mixture with millet and sorghum produced an alcohol content of 25 % for the first 100 mL aliquot while fruit wastes juice mixture without millet and sorghum yielded 22 %. This confirms the potential of millet and sorghum as an additional fermentable sugar in the production of bioethanol. Re-distillation of the first aliquots improved the quality of bioethanol to 91 % alcohol content. Bioethanol production from fruit wastes offers significant environmental advantages including reduced landfill waste and reduced emissions of greenhouse gases due to decomposition. This process enhances resource efficiency by converting low-value agricultural residues into biofuel thus, supporting circular economy. Bioethanol is a renewable energy source that reduces carbon emissions and non-renewable resource reliance, thereby promoting sustainable energy practices. The use of fruit wastes mixture rich in natural sugars, supplemented with millet and sorghum as additional fermentable sugars, has improved bioethanol yield. Additionally, the application of a range of technologies from pre-treatment, fermentation to distillation that avoid use of corrosive chemicals has contributed to improved environmental management practices.

日益增长的全球能源消耗和化石燃料燃烧产生的二氧化碳排放在现代构成了一个重大问题。由于从石油来源获得的燃料枯竭及其相关的环境影响，现在需要替代能源。水果废料可以用来制造生物乙醇，这有可能减少污染和二氧化碳的排放。本研究以水果废弃物为原料，通过发酵和蒸馏生产生物乙醇。对水果废弃物进行物理预处理后得到的果汁平均可溶性固形物含量为9.7±0.06°白利度。用高粱和小米粉对果汁进行浓缩，以提供额外的可发酵糖。在前100 mL中，谷子和高粱混合果汁的酒精含量为25%，而不含谷子和高粱的果汁的酒精含量为22%。这证实了小米和高粱作为生产生物乙醇的额外可发酵糖的潜力。第一批等分的再蒸馏将生物乙醇的质量提高到91%的酒精含量。从水果废料中生产生物乙醇具有显著的环境优势，包括减少填埋废物和减少由于分解而产生的温室气体的排放。这一过程通过将低价值的农业残留物转化为生物燃料来提高资源效率，从而支持循环经济。生物乙醇是一种可再生能源，可减少碳排放和对不可再生资源的依赖，从而促进可持续能源实践。利用富含天然糖的水果废物混合物，补充谷子和高粱作为额外的可发酵糖，提高了生物乙醇的产量。此外，从预处理、发酵到蒸馏等一系列技术的应用，避免了使用腐蚀性化学品，有助于改善环境管理实践。

Agro-photovoltaic (APV) technology addresses the challenges of land-use competition by enabling simultaneous solar power generation and food production, thus mitigating potential economic, ecological, political, and social conflicts in Bangladesh's future energy landscape. This study investigates the growth and yield of shade-tolerant crops, including tomato, brinjal, green chili, lettuce, aloe vera, under shaded and non-shaded conditions. Key plant growth parameters such as height, number of leaves, flowers, fruits, and fruit weight are measured to evaluate crop performance in the APV system. The Land Equivalent Ratio (LER) is utilized to compare the efficiency of food and energy production in APV systems against traditional monoculture farming, identifying optimal crops for APV integration. Energy generation from a stand-alone APV (SAPV) system is measured and simulated using PVsyst software to optimize system performance and maximize power output. Results indicate that brinjal, lettuce, aloe vera exhibit yield advantages in the APV system, while green chili show disadvantages, and tomato demonstrates no significant difference. The SAPV system achieves an average yearly performance ratio of 75.4 % and a solar fraction (FR) of 0.914, consistently meeting energy demands with an average daily energy production of 1.157 kWh. This study highlights the feasibility of APV systems as a sustainable model for integrated food and energy production in Bangladesh, demonstrating their potential to enhance land-use efficiency and contribute to the nation's energy and agricultural resilience.

农业光伏（APV）技术通过同时实现太阳能发电和粮食生产，解决了土地使用竞争的挑战，从而减轻了孟加拉国未来能源格局中潜在的经济、生态、政治和社会冲突。本研究考察了番茄、茄子、青椒、生菜、芦荟等耐阴作物在遮荫和非遮荫条件下的生长和产量。通过测量植物生长的关键参数，如高度、叶数、花数、果实数和果实重量，来评估APV系统中的作物性能。土地等效比（LER）用于比较APV系统与传统单一栽培农业的粮食和能源生产效率，确定APV整合的最佳作物。使用PVsyst软件测量和模拟独立APV （SAPV）系统的发电量，以优化系统性能并最大化功率输出。结果表明，茄子、生菜、芦荟在APV体系中表现出产量优势，青椒表现出劣势，番茄表现出不显著差异。SAPV系统的年平均性能比为75.4%，太阳能分数（FR）为0.914，平均每日发电量为1.157千瓦时，始终满足能源需求。本研究强调了APV系统作为孟加拉国粮食和能源综合生产的可持续模式的可行性，展示了它们在提高土地利用效率和促进国家能源和农业复原力方面的潜力。

The push to decarbonize the energy sector by incorporating renewable sources is increasing the complexity of power plant operations. One potential solution is to digitize power plants through digital twin (DT) technology, which can improve operational efficiencies and reduce maintenance costs. However, the application of DT in power plants remains in its early stages, with no existing implementations focused on gasification technology. This study aims to develop a comprehensive digital twin framework for a biomass gasification power plant with CO2 capture (DT-BGPP).

An overview of existing DT research in power plants and their classifications was conducted to assess the current state of the field and identify gaps. Based on this analysis, essential characteristics for the DT-BGPP framework were defined, leading to the identification of its main components. The classification revealed a common gap in mid-tier categories, with most available power plant Dts lacking complete bidirectional data flow with their physical counterparts. The key components of DT-BGPP include a high-order science-informed dynamic model, a data-driven model, actual data, pre-executed localized simulations, and a system genome.

Recommendations for advancing the proposed DT-BGPP include establishing connections between all framework components to achieve a fully integrated digital twin for a biomass gasification power plant with CO₂ capture.

通过引入可再生能源来推动能源部门脱碳的努力增加了发电厂运营的复杂性。一个潜在的解决方案是通过数字孪生（DT）技术将发电厂数字化，这可以提高运营效率并降低维护成本。然而，DT在发电厂的应用仍处于早期阶段，目前还没有专注于气化技术的实施。本研究旨在为具有二氧化碳捕集（DT-BGPP）的生物质气化发电厂开发一个全面的数字孪生框架。概述了电厂现有的DT研究及其分类，以评估该领域的现状并确定差距。在此基础上，定义了DT-BGPP框架的基本特征，从而确定了其主要组成部分。该分类揭示了中间类别的普遍差距，大多数可用的发电厂Dts缺乏与其物理对应的完整双向数据流。DT-BGPP的关键组成部分包括高阶科学动态模型、数据驱动模型、实际数据、预执行的局部模拟和系统基因组。推进拟议的DT-BGPP的建议包括在所有框架组件之间建立连接，以实现具有二氧化碳捕获的生物质气化发电厂的完全集成数字孪生。
