National Marine Renewable Energy Centers

1. National Marine Renewable Energy Centers Northwest National Marine Renewable Energy Center (NNMREC) • University of Washington (tidal) • Oregon State University (wave) • National Renewable Energy Lab (NREL) Southeast National Marine Renewable Energy Center (SNMREC) Hawaii National Marine Renewable Energy Center (HINMREC) • Florida Atlantic • Ocean Current • University of Hawaii • Wave, OTEC

2. NNMREC Objectives • Develop a full range of capabilities to support wave and tidal energy development. • Center activities: • Facilitate technology commercialization, • Inform regulatory and policy decisions, • Close key gaps in understanding, and • Educate the first generation of marine renewable energy engineers and scientists.

3. Environment Acoustics Dynamic Effects Benthic Ecosystems Sediment Transport Social Fisheries/Crabbing Outreach/Engagement Existing Ocean Users Local/State Economy Technology Testing and Demonstration Site Characterization Advanced Materials Device and Array Design/Modeling Virtual Center Organization

4. National Tidal Energy Platform • Energetic tidal resource,buta smoother transition from lab to field • Capability to test a range of device scales and technology readiness levels • Close proximity to electrical grid • Close proximity to maritime operation and manufacturing capabilities • Outside of vessel traffic lanes • Does not conflict with pilot or commercial deployment plans Snohomish PUD Project Everett Potential Site Seattle

5. Infrastructure Concept Monitoring Node Test Berth • Intermediate to full-scale testing at a single location (TRL 7-9) • Cabled to shore and grid connected • Environmental and performance monitoring nodes Berth B (30m) Water Depth (m) Berth A (20 m) Berth C (50 m)

11. Establishing Context for Observations Overnight Lull in Shipping Strong Currents First Run for Passenger Ferry Automatic Identification System Recording Hydrophone Doppler Profiler

12. Tidal Micropower • Oceanographic measurements are fundamentally power limited • Integrated energy harvesting could provide 10-20 W continuous power • Modular alternative to cabled observatories Support Frame Helical Turbine Generator

13. Rivers and Constructed Channels • Potential for power generation from in-stream turbines installed in the fast-moving waters downstream from Columbia River dams • Incremental environmental impact should be very small • In-stream turbines for flow control and power generation as potential alternative for energy-dissipating sluice gates

14. Deep Water Offshore Wind • WA and OR: 300 GW resource • Floating platform technology required for deep water • Platforms can be built and systems assembled in WA and OR UW and OSU PIs currently responding two 2 major funding announcements by US DOE • PPI currently installing full-scale demo unit off Portugal • Initial study on environmental impacts and permit streamlining for PPI Wind-Wave Float technology completed by UW-NNMREC

15. Conclusions • Marine energy Centers are developing capabilities to move technology from concept to commercialization. • Need for broad and sustained partnerships between Centers, industry, and public stakeholders. • Opportunity for universities to solve challenges and to train the first generation of marine energy engineers.
