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. In Operations Research, the Green Flexible Job Shop Scheduling Problem (FJSP) addresses production planning decisions incorporating resource, environmental, and economic objectives. The Energy Procurement Problem (EPP) aims to efficiently acquire energy resources. In the literature, existing approaches for energy-aware scheduling neglect to procure energy from sources such as an uncertain dynamic energy market, RES, and ESS. We aim to close this research gap and propose a two-level approach based on a memetic Non-dominated Sorting Genetic Algorithm (NSGA-III) and linear programming with the goal of minimizing the makespan, energy costs, and emissions of a schedule, incorporating dynamic energy prices and emissions, RES, and ESS. We evaluate the approach in computational experiments using FJSP benchmark instances from the literature as part of a rolling horizon approach with real energy market data. We investigate the impact of RES and ESS by presenting estimated Pareto fronts, showing potential savings in energy cost and carbon emissions.</div></div>","PeriodicalId":100252,"journal":{"name":"Cleaner Energy Systems","volume":"10 ","pages":"Article 100178"},"PeriodicalIF":0.0,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143349620","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The analysis is parametric by investigating different design scenarios, as well as there is optimization aiming at the maximization of energy efficiency.

Pertinent solid fuel properties were measured to characterize fuel performance ranges. Environmental implications were also assessed through emissions measurements. SD emerges with the lowest relaxation ratio (1.39), indicating superior stability during transportation.

CH (27.93 %wt.) presents higher igniting potential, while CC and PKS may necessitate combustion-enhancing additives for ignition. CC (12.34 ± 2.25 wt. %) yields lesser ash, potentially enhancing boiler performance and guaranteeing minimum maintenance as compared with the other briquette samples.

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. <em>Re</em>-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.</div></div>","PeriodicalId":100252,"journal":{"name":"Cleaner Energy Systems","volume":"10 ","pages":"Article 100177"},"PeriodicalIF":0.0,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143288087","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As the world faces the severe consequences of climate change, the transition to renewable energy (RE) has become a critical focus of sustainable development strategies. Renewable energy sources (RES) such as solar, wind, and biomass are not only environmentally friendly but also essential for achieving long-term energy security and economic stability. The importance of RE is underscored by the United Nations Sustainable Development Goals (SDGs), particularly SDG-7, which aims to ensure access to affordable, reliable, sustainable, and modern energy for all. SDG-7 highlights the necessity of increasing the share of RE in the global energy mix, improving energy efficiency, and promoting international collaboration to enhance clean energy research and technology. This research explores how Bangladesh can achieve a 100 % reliable and adaptable renewable energy (RE) output by 2050, focusing on the transition away from gas, coal, and oil-based power systems as the primary strategy for reducing fossil carbon emissions. The study examines the pathways to establishing a fully decarbonized and cost-effective energy grid in Bangladesh, emphasizing the challenges of converting the existing non-renewable power grid into a flexible and reliable RE system. From both technological and energy perspectives, the research investigates alternative methods and technologies to conventional fossil-dependent power systems and their potential to lead Bangladesh into a post-fossil fuel era. As a result, the proposed Carbon-free Advanced Power Network (CAPN) 2021–2050 model will offer the most cost-effective and environmentally friendly energy generation solution, with minimal greenhouse gas emissions and a fully carbon-free output. Intelligent energy management systems will play a key role in this transition.

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.
