  2. Marine and Hydrokinetic Technologies • Wave Energy can be captured from offshore, near shore, and shore based locations. It is driven by wind blowing over water creating waves from which energy is captured. • Tidal Energy can be captured from the ebb and flow of tides, thus the tidal devices change orientation with the tide. It is driven by the gravity of the moon and sun and can be predicted efficiently (better than wind and solar technologies). • Current Energy can capture the energy from moving ocean, tidal or river currents. • Ocean Thermal Energy Conversion (OTEC) uses the ocean’s natural thermal gradient to drive a power-producing cycle.

  11. Performance and Effects Modeling Tidal Turbine Wakes Numerical Modeling Effect of Wave Array Field and Laboratory Measurements Tidal Turbine Performance

  12. Advanced Materials Corrosion Foul Release Coatings Composite Aging Biofouling

  13. Prioritization of Environmental Research High Moderate Low Scientific Uncertainty Potential Significance Low Moderate High Polagye, B., B. Van Cleve, A. Copping, and K. Kirkendall (eds), (2011) Environmental effects of tidal energy development.

  14. Monitoring Static and Dynamic Effects Stereo Optical-Acoustical Camera System • Joslin, J., B. Polagye, and S. Parker-Stetter (2012) Development of a stereo camera system for monitoring hydrokinetic turbines, MTS/IEEE Oceans 2012, Hampton Roads, VA, October 19-14.

  15. Marine Renewable Energy Observatories? Snohomish Public Utility District Pilot Project (Puget Sound, Admiralty Inlet) • Tidal energy projects as observing nodes? • Opportunity to expand networks into harsher environments without large investments • Potential to leverage best practices and existing capabilities Two (200 ton) nodes on the seabed with 8+ fiber optic channels to shore and 2 kW available power for instrumentation

  16. Estuarine Circulation Modeling • Idealized, high-resolution model of an estuary-fjord-ocean system is used to study effect of turbine array placement over the fjord sill • Turbine array enhances turbulent mixing over the sill, leading to local enhancement of exchange circulation Average Condition without Turbines Changes due to Turbines
