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 […]

Investigations on Marine Hydrokinetic Turbine Foil Structural Health Monitoring Presented at GMREC METS

Structural health-monitoring (SHM) systems can provide key information to improve marine hydrokinetic (MHK) device management: reduce operations & maintenance costs, mitigate failures, and improve capacity factor. While present systems include instrumentation to measure power output, few adequately monitor mechanical loads and structural response, which are equally important for determining device performance and integrity. Fiber-optic Bragg […]

Biofouling Studies on Sandia’s Marine Hydrokinetic Coatings Initiated at PNNL’s Sequim Bay

Sandia’s Materials & Manufacturing Reliability Program has begun testing their novel marine hydrokinetic (MHK) coatings at the Sequim Bay facility, which is a part of Pacific Northwest National Laboratory (PNNL). Tests will reveal anti-biofouling efficacy of coatings developed for MHK technology and of commercial coatings. Over 150 coupons (1×1, 3×3, and 8×8 inches) will be […]

Wind Generator Modeling

Sandia finalized and submitted the updated “WECC Wind Power Plant Dynamic Model­ing Guide” and the “WECC PV Power Plant Dynamic Modeling Guide” to the Technical Studies Subcommittee at the Western Elec­tricity Coordinating Council (WECC). These dynamic modeling guides present the second-generation generic models as speci­fied in the January 23, 2014 WECC report. The WECC generic […]

Energy Department Awards $7M to Advance Hydrogen Storage Systems

On May 19th, the DOE announced $7M for six projects (five in California + PPG Industries in North Carolina) to develop lightweight, compact, and inexpensive advanced hydrogen storage systems that will enable longer driving ranges and help make fuel-cell systems competitive for different platforms and vehicle sizes. These advances in hydrogen storage will be critical […]
