Industrial poultry houses play an important role in the food supply chain but are also major consumers of energy and sources of greenhouse gas emissions. A key challenge is the reduced efficiency and lifespan of cooling systems caused by calcium and mineral buildup on evaporative pads, which increases energy use and maintenance costs. There is an urgent need to address this issue to improve system performance and sustainability. This study explores the potential of integrating locally available materials, such as palm fiber, palm leaves, and the Stipa plant, to enhance the performance and longevity of evaporative cooling systems in poultry houses. An experimental setup was developed to evaluate a prototype poultry house equipped with an integrated humidification system and fans, specifically designed and tested under the arid climatic conditions of Algeria. The best-performing configuration was assessed based on key parameters such as dry- and wet-bulb temperature reduction, relative humidity variation, pad thickness, and overall cooling efficiency. The results demonstrated that palm fiber significantly enhanced cooling performance, achieving a temperature drop of 18.1 °C and a cooling efficiency of 73.9%. Utilizing locally available materials not only improved the cooling performance but also reduced system costs, offering a more sustainable and economically viable solution for poultry farming in arid regions.

The rapid emergence of electric vertical takeoff and landing (eVTOL) air taxis presents both opportunities and challenges for sustainable urban energy systems. This study develops the Nationwide Energy Estimation for Air Taxis (NEAT) model, an integrated agent-based simulation framework that couples behavioral mode choice with detailed energy estimation to assess the large-scale effects of air taxi deployment in 15 of the most congested U.S. cities. Results indicate that shifting a portion of travelers to eVTOLs during peak periods can reduce on-road energy use by 3.35% on interstate highways and 6.92% on arterial roads nationwide, while alleviating traffic congestion and improving fuel economy for remaining vehicles. By capturing direct energy consumption of air taxis alongside systemic road-network effects, this study provides a robust technology assessment of eVTOL integration at city and national scales. The findings highlight the potential of aerial mobility to contribute to sustainable energy transitions.

Energy structure transformation of power generation enterprises is the key to achieving power low-carbon transformation. Renewable portfolio standard (RPS) is widely used to promote energy structure transformation. However, the mechanisms by which RPS affect energy structure transformation, and the optimal design of RPS have not been thoroughly explored yet. To address this gap, this study aims to explore the regulatory effects of fixed quotas and dynamic quotas on the energy structure transformation of power generation enterprises. Results indicate that both types of quotas can effectively promote the energy structure transformation of power generation enterprises with low proportion of renewable energy electricity. However, for power generation enterprises with high proportion of renewable energy electricity, fixed quotas may lose incremental effectiveness, and dynamic quotas may alleviate this specific effect. The research results provide policy implications for optimizing RPS policy and promoting enterprise energy transformation.

Reliable and scalable photovoltaic (PV) fault monitoring ensures high energy efficiency and low operational costs of large-scale solar farms. This paper proposes a new two-step deep learning-based architecture which combines the attention-based YOLOv12 detector with a small custom CNN to classify fine-grained PV defects. In contrast to the current single stage designs, the proposed design does not depend on fault localization and severity to classify faults. This enhances the ability of the design to resist small and visually insignificant faults like micro-cracks, dust, and hotspots without compromising edge placement capability. It is shown that the framework has good generalization and practical viability as indicated by the cross-dataset evaluation, ablation studies, and edge-device benchmarking. Experimental evidence demonstrates that it has high detection rates with an [email protected] of 98.7%, recall of 98.8%, and real time inference on embedded devices.

The regional energy transition under the goal of carbon neutrality confronts both constraints of energy water scarcities, with energy-water nexus critically shaping sustainable pathways. Climate change impacts must also be assessed when analyzing water resource constraints. This study established a method for evaluating energy-water synergy technologies in regional transition scenarios based on prospective life cycle assessment (PLCA), which used the data from Low Emissions Analysis Platform (LEAP) scenario inventories linked with LCI parameters. Subsequently, this method was applied to evaluate five environmental impacts (ADP, EP, FAETP, GWP, TFU) of Polycrystalline silicon photovoltaic power generation technology, Onshore wind power generation technology, and Coal-fired power generation deployed nine different carbon capture technologies in Shaanxi Province from 2020 to 2060. The results showed that Onshore wind power generation technology exhibited minimal environmental impacts (EIs) in 2020, while deploying post-combustion membrane carbon capture will greatly reduce the impacts of coal-fired power generation. Renewable energy impacts are concentrated in material production, while over 90% of carbon capture system impacts occur during operation. Except for Onshore wind power generation technology, other energy-water synergy technologies reducing more than 20% EIs, driven by decarbonized material production for renewables and optimized adsorption efficiency in carbon capture systems. Considering the constraints and technological maturity of different development stages, Shaanxi should prioritize wind and photovoltaic power generation expansion before 2030, scale solar-wind hybrid systems during 2030–2060, and deploy physical adsorption-based post-combustion technologies for coal-fired power generation. This study provided decision support for similar regions choosing energy-water synergy technologies under energy transition.

The transition to sustainable energy systems requires advanced nuclear technologies capable of providing high-temperature heat and hydrogen for industrial applications. High Temperature Gas-cooled Reactors (HTGRs) have emerged as a promising option for cogeneration, enabling flexible deployment across multiple scales and sectors. This study explores the potential path from technology demonstration to commercialisation of HTGRs, with particular emphasis on their application to industrial cogeneration. The paper describes the design philosophy and target applications, highlighting end-user requirements and technical configurations for both HTGR-POLA and the GEMINI+ reactor design. Safety aspects are examined to assess inherent and engineered features supporting deployment. A techno-economic evaluation, based on defined assumptions and modelling approaches, provides insights into cost, performance, and competitiveness relative to alternative energy systems. The findings demonstrate that HTGR-based cogeneration can meet diverse industrial needs while contributing to decarbonisation goals. However, successful commercialisation requires a stepwise approach from pilot-scale demonstrations to market entry, supported by favourable policies, regulatory alignment, and stakeholder engagement.

Microbial fuel cells (MFCs) are a promising technology for the production of electricity whilst cleaning waste. In order to gain a better understanding of the wider range of applications where this technology could be implemented, volatile fatty acid-based waste streams were tested as substrates in a rigorous, 12-unit experimental regime. Fermentation can be performed at acidic, neutral and alkaline pHs, with different concentrations. Polarisation experiments were performed to establish the maximum power point and corresponding external resistance applied. Additionally, assessment of performance stability was measured over 40 h under a fixed working load of 1 kΩ. This study investigated MFC performance under four initial pH values and three VFA concentrations, designed to represent the real conditions an MFC might experience. MFCs at pH levels of 7 and 8.5 maintained or increased performance as anolyte concentration increased. Maximum power was achieved under high concentration at pH 8.5, reaching 283 µW (10.5 mW/m2). MFC performance was limited at lower concentrations, however clear reduction in performance was witnessed at both medium and high concentrations for the pH extremes 5.5 and 10.

Wind turbines experience stochastic wind loads, which severely affect and reduce their service life. Thus, the article analyzes the load-sharing performance of the closed differential planetary gear trains under stochastic loads. Firstly, the stochastic wind speed is converted into a fluctuating torque with an Auto Regressive Moving Average approach. Secondly, a load-sharing model of the gearbox under stochastic load was established. Then, the load-sharing coefficients of a wind turbine under maximum torque, rated torque, and stochastic torque at a mean wind speed of 12 m/s were investigated. Lastly, load-sharing experiments for the gearbox were conducted under four distinct torques to validate the theoretical model.

To alleviate issues such as inherent differences in lithium-ion battery production and manufacturing, as well as aggravated inconsistency of battery systems caused by complex and variable practical scenarios, reduce the adverse effects and improve performance, this study proposes a hierarchical active equilibrium architecture that considers both consistency equilibrium and aging equilibrium. The proposed algorithm accurately identifies the batteries that require equilibrium, ensuring that the SOC deviations of individual batteries tend to be consistent, with an overall deviation not exceeding 1.0%. The continuous effect of active equilibrium eliminates the inhibition of aged batteries on the capability of normal batteries, which ultimately reaches 95.39 Ah with a capacity fade of only 1.03%. Multi-scenario tests in low temperatures show that the capacity of the battery gradually increases, compared with the battery without equilibrium. The capacity fade rate corresponding to the equilibrium algorithm achieves improvements of 82.05% and 16.81%, respectively. Finally, validation of the effectiveness and real-time performance with practical battery modules shows that inconsistencies in the open-circuit voltage (OCV) among individual batteries are improved, with the capacity fade being less than 2%, and the algorithm meets the requirements for real-time performance during practical hardware deployment. This study provides novel technical insights for the practical scenarios.

According to Sustainable Development Goal 7 (SDG 7), shifting toward cleaner energy carriers is crucial. Hydrogen is one of the most viable and credible alternatives to the conventional fossil fuels owing to its environmental benefits and versatility. However, the increase in use of hydrogen necessitates advancements in hydrogen production and storage technologies. Electrolyzers are among the most commonly used technologies applicable for production of hydrogen. These systems need electricity, which can be supplied from various sources. Employment of clean energy technologies to power the electrolyzer would be beneficial in terms of environmental impact and fossil fuel consumption. Solar photovoltaic (PV) cells are applicable systems to provide required electricity of the electorlyzers in clean manner. This paper reviews researches on the development of solar PV systems for power supply of electrolyzers. Results from the reviewed studies revealed that making use of PV cells offers advantages, including reduced greenhouse gas emissions and the ability to operate as stand-alone systems in remote areas. Furthermore, hybrid energy systems composed of PV cells and other technologies, such as diesel generator and/or wind turbines, can enhance reliability and economic feasibility.
