Overview

The Northwest National Marine Renewable Energy Center (NNMREC) is a DOE-funded partnership between Oregon State University and the University of Washington.

  • Oregon State University will be responsible for wave energy issues.
  • University of Washington will be responsble for tidal energy issues.
  • Both will collaborate on outreach activities and information dissmenation.

Vision

The role of the Northwest National Marine Renewable Energy Center is to close key gaps in understanding of marine energy and to inform the public, regulators, research institutions, and device and site developers.

Activities

Tidal energy activities are structured around four key areas:

  1. Instrumentation for cost-effective characterization of sites and devices
  2. Optimization of arrays with respect to device orientation and placement
  3. Modeling of environmental effects of extraction for both near-field and far-field
  4. Improved reliability and survavibility of devices through use of advanced composites

These will be carried out in three phases.

Partners

The DOE funds are matched at a 50% level by contributions from the University of Washington and the Center partners. This is to ensure that the Center is a true public-private partnership and strives to meet the needs of all marine energy stakeholders. Our currents partners include:

National Renewable Energy Laboratory
www.nrel.gov

The National Renewable Energy Laboratory (NREL) is the nation's primary laboratory for renewable energy and energy efficiency research and development (R&D).

NREL's mission and strategy are focused on advancing the U.S. Department of Energy's and our nation's energy goals. The laboratory's scientists and researchers support critical market objectives to accelerate research from scientific innovations to market-viable alternative energy solutions. At the core of this strategic direction are NREL's research and technology development areas. These areas span from understanding renewable resources for energy, to the conversion of these resources to renewable electricity and fuels, and ultimately to the use of renewable electricity and fuels in homes, commercial buildings, and vehicles. The laboratory thereby directly contributes to our nation's goal for finding new renewable ways to power our homes, businesses, and cars.


Pacific Northwest National Laboratory
www.pnl.gov

Pacific Northwest National Laboratory's research goals are to strengthen U.S. scientific foundations for innovation, increase U.S. energy capacity and reduce dependence on imported oil, prevent & counter terrorism and the proliferation of weapons of mass destruction, and to reduce the environmental effects of human activities and create sustainable systems. PNNL is also the only national lab with a marine sciences division.

PNNL and NNMREC have signed a memorandum of understanding (MOU) to carry out research and development activities for tidal energy devices, with a particular focus on environmental characterization and risk assessment.


Public Utility District of Snohomish County No. 1
www.snopud.com

Snohomish PUD is presently moving towards the permiting of a pilot-scale facility in Northern Admiralty Inlet of the Puget Sound. This work is funded under a separate cost-sharing agreement with DOE.

The District is the second-largest publicly owned utility in the Pacific Northwest and the twelfth largest in the nation in terms of customers served. The District is a municipal corporation of the state of Washington, formed by a majority vote of the people in 1936 for the purpose of providing electric and/or water utility service. The District began providing electric service in 1949 and currently serves an area of 5,700 square kilometers, encompassing all of Snohomish County and Camano Island. The District's service territory is growing rapidly, with projections estimating 8,000 to 10,000 new connections per year and a resulting annual load increase of 15 to 20 average megawatts (aMW).


BioSonics Inc.

BioSonics is a world leader in hydro-acoustic fish detecting and monitoring. They are collaborating with the Center on the instrumentation package for site and device characterization.


Electric Power Research Institute (EPRI)
www.epri.com

EPRI jump-started ocean renewables in the United States with a series of reports on wave and tidal energy in 2006. Since then, the EPRI ocean energy team under Roger Bedard has undertaken a number of additonal resource assessments, site feasibility studies, and technology characterizations.


Verdant Power

Sound & Sea Technology is a Woman-Owned Small Business Enterprise with a staff of highly experienced ocean engineering and maritime security experts, executing projects for government and commercial clients worldwide. Sound & Sea Technology was established in March 1999 to meet the need for experienced, senior-level expertise in ocean engineering for a broad range of undersea and coastal projects, specifically including renewable ocean energy. This specialized ocean engineering capability is often critical to the success of projects that include an ocean system. Since its inception, Sound & Sea has completed more than 200 successful projects, including design and installation of wave and tidal energy systems.


NOAA: National Marine Fisheries Service
www.nmfs.noaa.gov

NOAA Fisheries Service is dedicated to the stewardship of living marine resources through science-based conservation and management, and the promotion of healthy ecosystems.

NMFS has provided the Center with a fish tag hydrophone to monitor fish equipped with acoustic tags. The receiver is currently deployed in Admiralty Inlet, WA as part of the Center's site characterization activities.

Washington Department of Ecology
www.ecy.wa.gov

The Mission of the Department of Ecology is to protect, preserve and enhance Washington’s environment, and promote the wise management of our air, land and water for the benefit of current and future generations.

The Department of Ecology is providing a dissolved oxygen sensor as part of a broad effort to study water quality in Puget Sound. The sensor will be deployed in Admiralty Inlet, WA as part of the Center's site characterization activities.

An important component of Center activities involves outreach, so if you would like to partner with the Center, please contact us.
