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 [...]

Upgrades to SNL-EFDC: A Tool to Balance Marine Hydrokinetic Energy Generation Efficiency with Environmental Response

SNL-EFDC is an open-source tool developed to support the marine renewable-energy industry by enabling simultaneous evaluation of array power production and environmental effects, facilitating optimal device placement. SNL-EFDC is an augmented version of US EPA’s Environmental Fluid Dynamics Code (EFDC) that has been well validated against real world river, lake, tidal, and other coastal environments. [...]

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 [...]

SNL-SWAN Beta Code Development: Frequency-Dependent Wave-Energy Converter Module

Sandia is developing accurate methods to simulate altered wave propagation due to the operation of wave farms by enhancing the open-source spectral wave model, SWAN. The new model, SNL-SWAN, remains open source and will help the wave-energy converter (WEC) industry assess the potential environmental effects created by changes in wave climates associated with the deployment [...]

Sandian’s Receive Hydrogen and Fuel Cell Program Achievement Award

On June 17th at the 2014 DOE EERE Fuel Cell Technology Office (FCTO) Annual Merit Review in Washington DC, Sandian’s Christopher San Marchi (manager of Sandia’s Hydrogen and Metallurgy Science Dept.) and Brian Somerday (also in the Hydrogen and Metallurgy Science Dept.) received a DOE Hydrogen and Fuel Cell Program achievement award for their research [...]
