Waste-to-energy (WtE) technologies are widely recognized for their greenhouse gas mitigation potential by diverting waste from disposal sites and displacing fossil fuels with energy recovered from waste. However, their cost-effectiveness for carbon abatement remains underexplored. This study introduces the Levelized Cost of Carbon Mitigation (LCOCM) as a novel metric to assess the economic feasibility of WtE technologies in Iran. The LCOCM is particularly valuable in countries where carbon pricing mechanisms such as emission trading schemes (ETS) are not yet in place, thereby serving as an alternative decision-support tool for policymakers. The results show LCOCM values of $32/ton CO₂-eq for incineration, $14/ton CO₂-eq for anaerobic digestion (AD), and $7/ton CO₂-eq for landfill gas (LFG) recovery. Financial indicators confirm that LFG and AD are economically viable options for carbon-emission reduction, with NPVs of $1.9 billion and $1.1 billion, IRRs of 28 % and 13 %, and payback periods of 3 and 7 years, respectively, whereas incineration is not viable under current conditions. Sensitivity analyses further underscore the critical role of operational optimization—such as extended lifespans, improved energy yields, and minimized downtimes—in reducing the LCOCM. This study demonstrates the cost-effectiveness of WtE technologies for carbon mitigation and provides a replicable framework for sustainable energy and climate policy in emerging economies.</div></div>","PeriodicalId":11798,"journal":{"name":"Energy Reports","volume":"15 ","pages":"Article 108908"},"PeriodicalIF":5.1,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145736276","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, the manuscript explores the production of biodiesel from two varieties of mango seeds-Alphonso and Bangalora. It delves into various aspects, including the extraction process, transesterification, characterization, engine performance, and economic analysis. The oil extracted from Bangalora seed kernels yielded a maximum of 93.69 % biodiesel, outperforming the optimized conditions of 55°C, 60 min, 450 rpm stirring, 1 % catalyst, and 20 wt% ethanol. Qualitative analysis has confirmed that the composition of fatty acid ethyl esters in Bangalora biodiesel is superior in quantity compared to that of Alphonso. Bangalora biodiesel (B100) exhibits enhanced in-cylinder peak pressure and heat transfer rates under both 75 % and 50 % engine loading conditions. Its brake thermal efficiency, brake-specific fuel consumption, and indicated thermal efficiency are comparable to those of conventional diesel; it boasts an improved mechanical efficiency of 74.56 %, attributed to its higher cetane number. Despite minor differences in quality and quantity, both biodiesel variants demonstrate significant potential for engine performance and guarantee scale-up. The cost for one liter of biodiesel is $0.51, with a projected return of 62.95 % and a payout period of 15.88 years.

First, it aims to evaluate the environmental benefits obtainable by applying a power loss minimization algorithm to a three-phase induction motor compared to traditional field-oriented control algorithms under different working conditions. The optimized algorithm reduces all environmental impacts by approximately 15 %. A scenario analysis, based on different electricity production processes, highlights that the sustainability of electric powertrains increases by improving the share of renewable electricity in the production mix.

This paper proposes a novel multi-stage congestion management framework that integrates generator rescheduling using Particle Swarm Optimisation (PSO) with a severity-based, hierarchical application of demand-side strategies, specifically Real-Time Pricing (RTP) and Adaptive Load Shedding. The methodology is designed to progressively relieve congestion by activating increasingly stringent measures only when preceding steps prove insufficient. Simulations conducted on the IEEE 30-bus and IEEE 118-bus test systems under artificially induced congestion conditions demonstrate the effectiveness and scalability of the proposed framework. In the IEEE 30-bus case, the total generation cost decreases from 2280.90 USD/hr (post-congestion) to 1633.09 USD/hr, with all line flows restored within thermal limits. Application to the larger IEEE 118-bus system further validates the approach, reducing the generation cost from 335,965 USD/hr (congested) to 193,681 USD/hr after the complete three-stage process, i.e., a 42.35 % reduction, while total demand falls moderately from 6055 MW to 5579 MW, i.e., a 7.86 % as congestion is fully eliminated. Results show that although PSO-based generator rescheduling significantly reduces overloads, it is insufficient for full congestion clearance, therefore necessitating the successive deployment of RTP and adaptive load shedding. Compared to conventional single-method solutions, the proposed strategy achieves enhanced technical efficiency, demand-side flexibility, and operational robustness. This work contributes a scalable and adaptive solution for congestion management in emerging electricity markets, particularly in environments transitioning to market-based operation.</div></div>","PeriodicalId":11798,"journal":{"name":"Energy Reports","volume":"15 ","pages":"Article 108952"},"PeriodicalIF":5.1,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145921295","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Social impacts were surveyed from 120 households in the city of Douala. The energy analysis shows that carbonization is the most energy-intensive operation, whereas the drying of sawdust is the least energy-intensive operation. The energy consumed in making briquettes is 209.86 kWh, 223.68 kWh, 215.69 kWh, 214.95 kWh and 213.79 kWh respectively for briquettes P (100 % Padouk), I (100 % Iroko), A (75 % Padouk+25 % Iroko), B (25 % Padouk+75 % Iroko), and C (50 % Padouk+50 % Iroko).

International LPG trade is predominantly realized through maritime transport. This study leverages the CEPII database and Automatic Identification System big data to construct a multi-layer network model of global maritime LPG trade. Based on the unique characteristics of maritime LPG trade, we categorize the factors influencing its realization into three dimensions: supply-demand, maritime transport, and relational dynamics. Building on these dimensions, we develop a multi-layer network model for global maritime LPG trade. Key nodes and their importance are analyzed using network centrality metrics, including in-degree, out-degree, and total degree centrality, as well as in-eigenvector, out-eigenvector, and total eigenvector centrality. Furthermore, we apply core-periphery theory to examine the hierarchical structure (core-semi-core-periphery) of the global maritime LPG trade network. Finally, network stability is assessed through robustness analysis. Based on the analysis, the following conclusions can be drawn: (1) Form a dual core structure with the United States and China as the core in the supply and demand dimension; In terms of shipping, the Strait of Malacca has become an absolute hub with its central advantage, complemented by differentiated regional port clusters; In the dimension of trade relations, it is manifested as high-quality complementarity of regional subsystems and the \"scale quality imbalance\" of traditional major powers. (2) Structural Disparities Across Dimensions: There are significant structural disparities across different dimensions. The core nodes of the global marine LPG trade network are the United States (USA) and China, with semi-core nodes including the Strait of Malacca, Houston, the Suez Canal, Port Neches, Port Freeport, and the Strait of Hormuz. Major trading countries act as the primary driver, while maritime transport hubs serve as enabling carriers. (3) Stability Hierarchy Across Dimensions: In terms of stability, the supply-demand dimension of the global marine LPG trade network exhibits the highest stability, followed by the relational dimension, with the maritime transport dimension being the least stable.

Graph Neural Networks (GNN)-Smart Detect, a model for GNNs to improve accuracy and exceptionally robust uncertainty quantification in error of interconnected innovative grid components, is introduced in this study. GNN-SmartDetect exploits graph-structured information to capture topological dependencies among grid nodes and improves its anomaly detection and fault classification performance even under noisy and incomplete data situations. Our experimental data show that GNN-SmartDetect can detect 96.4 % of faults with outstanding performance, and two orders of magnitude lower false positive and false negative rates compared to the traditional models. Moreover, the built-in uncertainty quantification system provides dependable confidence levels by each detection and therefore allows operators to estimate risk and come up with proactive reactions in the face of threats whilst they are not known in grid conditions. It is also scalable and can be adapted to different grid configurations including microgrids and national grids, which shows that the model can be implemented in real time under Industry 4.0 operations smart grid operations.
