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.

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.

Phase 2
 Cable to shore-based infrastructure
(non-grid connected)
 Two device berths (TRL 7-8)
Phase 3
 Grid interconnection
 Two device berths (TRL 7-9)
NNMREC
National Tidal Energy Platform
 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
Snohomish
PUD Project
Everett
Potential
Site
 Close proximity to maritime operation
and manufacturing capabilities
Seattle
 Outside of vessel traffic lanes
 Does not conflict with pilot or
commercial deployment plans

Environmental Monitoring Motivation
 Site-specific information is
needed by multiple parties:
Site Developers
Optimal siting
Device
Developers
Design loads
Regulatory
Agencies
Environmental
context
 Existing information is insufficient
 Approaches to close knowledge
gaps are underdeveloped

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.
