The performance of a single VAWT placed around an offshore HAWT tower is evaluated, at various position (0°,45°,60°,90°) to determine the optimal position of VAWT for maximizing power output. The study maintains a constant gap of 5.4 m from the center of tower to the middle of turbine, with constant wind velocity of 8 m/s. A three-dimensional simulation is performed to assess the aerodynamic effect of accelerated flow and high velocity created by the tower on VAWTs power performance, and compared these results to those obtained without the HAWT tower. The results indicate that the tower structure creates regions of high wind speed and stagnation regions. VAWT power output is enhanced in the high-speed regions, while power output decreases in front of the tower due to stagnation effects. At 0°, the power coefficient is at a minimum of 0.0837, lower than that of turbines without the tower. At 60° and 90°, the coefficients improve to 0.4864 and 0.5487, respectively.

Replacing platinum (Pt) electrodes with titanium-mixed metal oxide (Ti-MMo) electrodes in neutral media significantly reduces production costs. The optimal hydrogen evolution rate (HER) was achieved at 4 V using a 3 % NaCl and 1 % H₂O₂ solution, producing 80 ml/min of hydrogen at a current of 12 A.

The findings highlight the potential of solar energy to reduce LCOH, making hydrogen production cleaner and more sustainable. The study encourages policymakers and investors to consider increased investment in this sector, as it could drive growth in the energy industry.

Consequently, securing accurate and up-to-date data on actual carbon emissions emerges as a critical imperative. This study systematically reviews recent research on real-time carbon monitoring in the AEC industry from 2010 to 2024, focusing on key aspects such as monitoring object, boundary, dynamic data acquisition method, carbon calculation method, and functional services. The research findings indicate that GPS, BIM, RFID, and Sensors are the primary technologies employed for real-time carbon monitoring, with Sensor technology uniquely suited for the full life cycle monitoring. However, their integration remains limited, hindering fully automated real-time monitoring. Current monitoring systems primarily focus on carbon monitoring, neglecting potential for carbon prediction and early warning functionalities. These systems offer homogeneous functions with limited integration. Furthermore, the study proposes a framework for developing comprehensive carbon monitoring systems in AEC industry from five aspects.

The Weather Research and Forecasting model (WRF) was used to run very high resolution (≈1 km²) simulations using the latest climate change scenarios (CMIP6 SSPs), to then calculate the wind power density, solar photovoltaic power density and future changes to water availability. A fully decarbonised electricity supply scenario was proposed based on a site selection algorithm that selects the most cost-effective source between wind and solar combined with changes to hydroelectricity. The results show that most of the study area is viable for solar photovoltaic while floating wind is the most cost-effective solution. Overall, wind power has the highest potential contribution to total electricity production, with 54 % for SSP2-4.5 and 46 % for SSP5-8.5.

In this study, a novel asynchronous stacked electrocaloric refrigeration device (ASERD) model is firstly proposed. The ASERD model enables simultaneous heat absorption and release within a single refrigeration cycle, thereby maintaining a significant vertical thermal gradient between the upper and lower electrocaloric sliding layers. This creates a “thermal wall” effect that impedes horizontal thermal reflux from the heat dissipation side to the microchip side, reducing the temperature at the microchip side by approximately 5 K compared to synchronous design. Secondly, six typical microchip local dynamic hotspots are designed to verify the ASERD model’s anti-interference ability to heat load fluctuations. During regulation process, the “thermal wall” effect continuously strengthens, resulting in increasing refrigeration performance. The maximum temperature rise is reduced by 9.87 K, 8 K, 9.51 K, 8.92 K, 6.85 K, and 6.98 K, respectively. Thirdly, two main regulation strategies for refrigeration performance enhancement are studied for ASERD model with higher degree of freedom: field intensity and motion frequency. In these two regulation strategies, two overregulated phenomena caused by heat conduction overshoot: temperature feedback and refrigeration reversal phenomenon are discussed in field intensity regulation. Based on above analysis, a hierarchical regulation strategy for refrigeration performance enhancement combining field intensity and motion frequency is proposed, further reducing maximum temperature rise by 10.65 K and 6.96 K compared to optimal single regulation. In summary, the feasibility of ASERD model is verified in principle, which achieves better refrigeration capability compared to conventional synchronous design. Besides, flexible regulation strategy for ASERD model is discussed to further improve the refrigeration performance. Therefore, the novel ASERD model demonstrates better potential application prospects.</div></div>","PeriodicalId":56019,"journal":{"name":"Sustainable Energy Technologies and Assessments","volume":"76 ","pages":"Article 104300"},"PeriodicalIF":7.1,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143777103","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To expand the PV windows application scenarios and reduce the cabin energy consumption, this paper proposes an innovative application of CdTe PV windows in ship-based moving condition. The dynamic variations in solar irradiation received angle depend on different energy converting orientations of PV window since the ship movements. Thus, PV windows can avoid non-uniform irradiation and partial shading, leading to better energy harvesting efficiency in solar energy capture when PV windows are connected in parallel. The comprehensive performance of PV windows is compared under two conditions: a mooring condition with a northwest-facing bow and a sailing condition with closed sailing routes. The results indicate that under sailing condition, the average power generation efficiency of PV windows increased by 65.05% and heat transfer was reduced by 57.47%.
