    The maximum wind energy of the most correlated points in an urban environment

    by George Efthimiou

    Energy Storage and Conversion, Vol.3, No.2, 2025;

    This study investigates the maximum wind energy potential of points that exhibit the highest correlation in an urban environment. A wind tunnel experiment that was simulated in a previous study using the Large Eddy Simulation (LES) methodology to generate wind speed time series at various locations within a complex urban setting. The analysis focuses on the correlation of wind speeds at different heights and spatial points, demonstrating a clear dependence on height, with maximum correlations generally increasing as height increases. This phenomenon is attributed to the disruption of turbulent eddies by buildings, which significantly influences the wind flow patterns. The Spectral Proper Orthogonal Decomposition (SPOD) technique is employed to calculate the maximum wind energy, revealing that the maximum values occur on building rooftops. Additionally, an empirical equation is proposed, relating the maximum wind energy to the distance between the most correlated points, with a relatively high correlation coefficient. The findings of this research have practical implications for the optimization of renewable energy resources, particularly in urban environments where wind flow is highly complex. This study contributes to the understanding of wind energy potential in urban settings, offering insights that could be valuable for the placement and design of wind turbines in such challenging environments. The study revealed a significant dependence of wind energy potential on spatial positioning and height, with maximum values occurring at rooftops. An empirical equation was developed to predict the difference in maximum wind energy based on the distance between highly correlated points, offering a practical tool for urban wind energy optimization. These findings provide actionable insights for the integration of renewable energy systems in complex urban settings.

    Energy Storage and Conversion, Vol.3, No.1, 2025;

    Nowadays, mainstream research on graphene trends towards employing environmentally friendly or green synthesis routes and precursors, and ensuing green graphene nanomaterials are shown to be highly beneficial for a range of scientific applications, from energy/electronics to engineering to biomedical arenas. Specifically, graphene has emerged as a leading contender for designing green or ecological energy conversion (solar cells, fuel cells) and energy storage (supercapacitors, batteries) devices/systems. In this perspective article, we basically aim to highlight state-of-the-art advancements of green-sourced graphene and related nanomaterials in today’s energy sectors. According to scientific endeavors so far on green graphene, its successful design, real-world energy conversion/storage device application, and commercialization depend upon resolving underlying challenges of synthesis/performance. We observe notable applications of green graphene in the fields of photovoltaics, fuel cells, capacitors, and batteries.

    Enhancing the performance and durability of high-temperature heat transfer fluids in industrial applications: A short review

    by Christopher Ian Wright

    Energy Storage and Conversion, Vol.3, No.1, 2025;

    This article discusses typical heat transfer fluids (HTFs), crucial for efficient heat transfer in various industrial processes. HTFs play an important role circulating heat within closed-system operations, such as chemical processing, and also in storing and transferring thermal energy, for example, in concentrated solar power plants. Selecting the right HTF is key, as it must be compatible with the specific temperature range of the operation, thermally stable at high temperatures, and compatible with system materials. Safety is also a crucial factor, both in terms of personal safety during handling of the fluid and environmental impact of fluids. Regular monitoring is also a key consideration when selecting and using a fluid. as the condition of the HTF and system are interlinked. Regular sampling and monitoring of the fluid’s condition helps to identify potential issues like oxidation, contamination, and thermal decomposition, and thus helps to prevent or slow degradation while sustaining optimal performance. Strategies for extending the lifespan of a HTF include routine monitoring and the utilisation of other technologies, as needed, to protect against oxidation (e.g., anti-oxidative additive packages) and volatile light-ends (e.g., installation of a light-ends removal kit). By adopting such measures, industries can reduce operating costs, minimize downtime, and improve overall system efficiency. The objective of this short review is to provide a brief overview of the main HTFs used in high temperature industries and offer insights into the importance of selecting the right HTF for a specific application, considering factors such as its thermal properties, chemical stability, and safety. The need for regular monitoring and maintenance is emphasized to ensure optimal performance and extend the lifespan of HTFs.

    A review on MXene (Ti3C2Tx) composites with varied sizes of carbon for supercapacitor applications

    by Ruby Garg

    Energy Storage and Conversion, Vol.3, No.1, 2025;

    MXenes belongs to a family of two‐dimensional (2D) layered transition metal carbides or nitrides which shows outstanding potential for various energy storage applications because of their high‐specific surface area, phenomenal electrical conductivity, outstanding hydrophilicity, and variable terminations. Of these different types of MXenes, the most widely studied member is Ti3C2Tx especially in supercapacitors (SCs). However, due to the problem of stacking and oxidation in MXene sheets, significant loss of electrochemically active sites happens. To overcome these issues, incorporation of carbon materials is carried out into MXenes for enhancing its electrochemical performance. This review aims to introduce various common strategies employed in synthesizing Ti3C2Tx, followed by a brief overview of latest developments in fabricating Ti3C2Tx/carbon electrode materials for SCs. The composition of Ti3C2Tx/carbon are summarized based on different dimensions of carbons, such as 0D carbon dots, 1D carbon nanotubes and fibers, 2D graphene, and 3D carbon materials (activated carbon, polymer‐derived carbon, etc.). Further, this review also aims in highlighting several insights on fabrication of novel MXenes/carbon composites as electrodes for application in SCs.

    Thermal imaging-based fault detection and energy efficiency analysis in a 1.6 MW photovoltaic system in Bağyurdu OIZ, Türkiye

    by Cihan Yalçın

    Energy Storage and Conversion, Vol.3, No.1, 2025;

    The present study assesses the influence of thermal imaging defect detection on the energy efficiency of a 1.6 MW solar power facility in the Bağyurdu Organized Industrial Zone (OIZ) in İzmir, Turkey. Thermal imaging has demonstrated efficacy in detecting serious problems in photovoltaic (PV) panels, including hot spots, inoperative modules, faulty connections, and shadowing, which substantially impact system performance. A comprehensive investigation revealed that around 15% of the photovoltaic panels displayed defects, resulting in a 16% decrease in system performance and an estimated yearly energy loss of 0.35 GWh. The study emphasizes the benefits of thermal imaging compared to conventional fault detection techniques, including its capacity for swift and non-invasive identification of localized overheating, which may lead to fires, and its ability to discern fluctuations in energy output due to shading or malfunctioning modules. The results underscore the necessity for routine thermal evaluations and maintenance to guarantee photovoltaic systems’ operational efficacy and dependability. This study enhances the sparse data on large-scale photovoltaic systems in Türkiye and illustrates the effectiveness of thermal imaging as an economical and accurate diagnostic instrument. Future studies should amalgamate thermal imaging with sophisticated diagnostic techniques, like electroluminescence testing and machine learning, to augment fault detection precision and optimize photovoltaic system efficacy.
