Northwest National Marine Renewable Energy Center USDOE Funded Center Center award announced September 18, 2008. USDOE support for up to 5 years at $1.25MM per yr. Minimum 50% non-Federal cost share UW $2.7MM OSU
$10.4MM Northwest National Marine Renewable Energy Center Benefits of Center Support the emerging fields of ocean and hydrokinetic energy with crucial capabilities for steady, reasoned development. Tap a significant renewable energy resource that is not now used in an environmental responsible manner. Through research and education and interaction with industry and stakeholders, help build the foundation for renewable
energy jobs in Washington. Northwest National Marine Renewable Energy Center Center Work Plan (UW) Mobile testing package: field measurements to select sites and assess site impact are expensive and timeconsuming. Mobile testing packages, methodologies & baseline habitat measurements, with advanced instrument arrangements, are required for integration into the industry and regulatory process. Environmental impacts modeling: testing cannot answer all the questions. Computational modeling at both estuary and device scales is necessary. This hydrodynamic modeling is one of key capabilities in helping to determine the capacity of an estuary to
support tidal turbines. Northwest National Marine Renewable Energy Center Work Plan (cont) Device and array optimization: Intelligent placement of turbines and spacing of arrays depends of several factors: water current versus depth, turbine wake interaction, and marine biology. Field measurements, computer modeling, and lab experiments are used to tackle optimization. Device reliability and survivability: The capabilities of the UW-FAA Center on Advanced Materials are used to study composite materials for ocean energy
devices. These materials have to ability to control bio-fouling and corrosion in sea water. Northwest National Marine Renewable Energy Center Tidal Resource Very localized resource Only economic in narrow channels Many different limits Existing uses Environmental effects Economics Recent, preliminary resource estimate
