Need for National Test Sites Lack of at-sea test facilities for marine renewable energy
is a major barrier to technology innovation.
Regulatory process currently weights ad hoc testing towards environmental monitoring.
A truly integrated test facility should address technology readiness, environmental effects, and cost effectiveness.
Opportunity for US to show worldwide leadership– Existing worldwide facilities only partially meet requirements.– Existing worldwide facilities are at resource and geographic
extremes.

National Tidal Energy Platform
Potential Site
Seattle
Everett
Snohomish PUD Project
Energetic tidal resource, but a 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

needed by multiple parties:
Optimal siting
Existing information is insufficient Approaches to close knowledge

Oceanographic measurements are fundamentally power limited
Integrated energy harvesting could provide 10-20 W continuous power
Modular alternative to cabled observatories
NNMREC
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
NNMREC
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
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
UW and OSU PIs currently
responding two 2 major funding announcements

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.
