benefits of 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.

Mobile testing package: field measurements to select sites and assess site impact are expensive and time-consuming. 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.

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.

tidal resource
Tidal Resource
  • Very localized resource
    • Only economic in narrow channels
  • Many different limits
    • Existing uses
    • Environmental effects
    • Economics
  • Recent, preliminary resource estimate
    • 650 MW rated electrical capacity in Admiralty Inlet (~5% reduction in tidal regime)
    • Effects of site development are cumulative
tidal turbines
Tidal Turbines
  • Two pilot tests proposed for Puget Sound
    • Snohomish PUD in northern Admiralty Inlet
    • Verdant Power/Navy around Marrowstone Island
  • Momentum worldwide for pilot and commercial projects

  • Surveys and long-term deployments to inform:
    • Site developers: cost & power projections
    • Device developers: wakes, efficiency
    • Regulators: potential effects

Baseline Biological Information

  • Marine Habitat information before project installation;
    • Bottom habitat
    • Submerged vegetation
    • Fish abundance, distribution, behavior
    • Marine mammal activity
  • Use Baseline data to guide project deployment & operation
  • Use Baseline data to guide operational monitoring needs
