Taller turbine towers would not only allow access to higher wind speeds and steadier conditions, but also to increased wind production time and maximized opportunities to harvest energy. This is true for parts of Europe and the United States where favorable wind conditions exist above 100 meters and electricity demand is relatively high. With this in mind, Corporate Technology (CT US) has partnered with Iowa State University to adapt the Hexcrete Concept — a structural engineering innovation used for tall bridge towers in suspension and cable-stayed bridges — to taller wind turbine towers.
The goal of the “Hexcrete Tower for Harvesting Wind Energy at Taller Hub Heights” project is to create a new wind turbine tower design and manufacturing concept for harvesting wind energy at 120 to 140 meter rotor hub heights, and reducing the per-kilowatt-hour cost of building and operating wind towers in the United States. CT US is performing design analysis and optimization for the wind tower designs that are created for this effort.
“For a long time, turbine manufacturers have aspired to building taller towers, because wind resources are more consistent and dependable at higher altitudes. This project has real potential for making this plan a reality,” said Kurt Bettenhausen, Head of the Automation & Control Technology Field at CT US.
