Sandia vertical axis wind turbines (VAWTs) demonstrate offshore advantages

Sandia National Laboratories has a long history of vertical-axis wind turbine, or VAWT, research that is the foundation for today’s innovations. Wind researcher Todd Griffith recently discussed vertical axis wind turbines (VAWTs) with Windpower Engineering magazine, noting that there are still many advantages to VAWTs over the conventional three-blade designs, especially when considering offshore duty. The Sandia [...]

Sandia and Partners Complete Phase I of a Vertical-Axis Deep-Water Offshore Turbine Study

Sandia and partners from the University of Maine, Technical University of Delft, Iowa State University, TPI Composites, and Texas A&M University have completed the first phase of a project to explore the feasibility of large-scale vertical-axis wind turbines (VAWTs) for deep-water offshore locations. The results of this conceptual study show the potential for significant cost [...]

Study Compares Floating-Platform Options for Offshore Vertical-Axis Wind Turbines

Spar-buoy and semi-submersible size comparison over design range. Sandia and the University of Maine recently published a Sandia technical report on floating-platform options for deep-water vertical-axis wind turbines (VAWTs). This analysis uses a 5 MW VAWT topside design envelope created by Sandia to compare floating platform options for each turbine in the design space. [...]

Innovative Offshore Vertical-Axis Wind Turbine Rotors

This project seeks to advance large offshore vertical-axis wind turbine (VAWT) rotor technology from concept to lab-scale prototype stage through four major research thrusts: innovative aeroelastic rotor conceptual design, deep-water system design and cost analysis, rotor material and manufacturing strategies, and subscale rotor prototype design & testing. VAWTs in deep-water have inherent advantages over [...]

Sandia Vertical-Axis Wind-Turbine Research Presented at Science of Making Torque from Wind Conference

In June, Brian Owens (in Sandia’s Analytical Structural Dynamics Dept.) and Todd Griffith (in Sandia’s Water Power Technologies Dept.) traveled to DTU Lyngby (Technical University of Denmark: Copenhagen, Denmark) to present Sandia research on deep-water multiple-megawatt vertical-axis wind turbines (VAWTs). High tip-speed ratios, low frequency structural vibration modes, and flexible blades of multiple-megawatt VAWTs can [...]

Offshore Ambitions for the Vertical-Axis Wind Turbine

Sandia National Laboratories is gearing up a recently launched project to test a range of ultra-large floating vertical-axis wind turbine (VAWT) designs, with the target of carving 20 percent out of the forecast cost of energy for deep-water installations. The U.S. engineering and science research facility’s $5M offshore VAWT rotor project is exploring [...]
