In a significant stride towards optimizing wind energy technology, researchers have uncovered promising insights into the efficiency of ducted small wind turbines. The study, led by Hasanali Khojasteh from the Faculty of New Sciences and Technology at the University of Tehran, Iran, and published in the *Journal of Environmental Energy and Economic Research*, delves into the potential of ducts to enhance energy production and reduce costs, particularly in areas with low wind speeds.
The research focused on a modified Wuxi Ruifeng 2 KW 48 V wind turbine equipped with two new ducts, designated as Sii and Prototype. By analyzing wind data from four distinct regions in Iran, Khojasteh and his team evaluated the annual energy production and Levelized Cost of Energy (LCOE) for the turbine both with and without the ducts. The findings revealed a nuanced picture of duct efficiency.
“In high wind speed areas, ducts have a minimal impact on increasing annual energy production and reducing energy costs,” explained Khojasteh. “In fact, they can sometimes negatively affect performance.” However, the study highlighted a significant advantage in low wind speed regions. “In areas with low wind speeds, ducts can increase annual energy production by up to four times and reduce energy costs by up to 2.5 times,” Khojasteh added.
This research holds substantial implications for the energy sector, particularly in regions where wind speeds are typically low. The use of ducts could potentially make small wind turbines more viable and cost-effective, thereby expanding the reach of wind energy technology. “This study opens up new possibilities for utilizing wind energy in areas previously considered unsuitable due to low wind speeds,” Khojasteh remarked.
The findings suggest that ducted wind turbines could play a pivotal role in the future of renewable energy, especially in urban and suburban settings where wind speeds are generally lower. As the world continues to seek sustainable and efficient energy solutions, this research provides a compelling case for further exploration and development of ducted wind turbine technology.
The study, published in the *Journal of Environmental Energy and Economic Research*, underscores the importance of innovative solutions in the renewable energy sector. As the energy landscape evolves, such advancements could pave the way for more widespread adoption of wind energy, contributing to a greener and more sustainable future.
