Marine and Hydrokinetic (MHK) Renewable Energy

Sustaining and Securing National Energy Needs with Water Power

mhk technologies
MHK 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 other MHK 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.

u s tidal power assessment
U.S. Tidal Power Assessment

Georgia Tech, in partnership with DOE, in June 2011 introduced a new database highlighting the energy potential available in the U.S. from ocean tides.

Hot Spots: Alaska, Maine, Washington, Oregon, California, New Hampshire, Massachusetts, New York, New Jersey, North and South Carolina, Georgia, and Florida (descending order)

*The extractable resource is not completely known; assuming 15% level of extraction, EPRI has documented 16 TWh/yr in Alaska, 0.6 TWh/yr in Puget Sound, and 0.4 TWh/yr in CA, MA, and ME.

federal interests in mhk development
Federal Interests in MHK Development
  • Remote Marine Power
    • Low cost, efficient, readily available and deployable electric power at remote locations (including military facilities) around the world.
  • MHK technology provides a great source of Baseload Power
  • Compete internationally to capture industry job creation/economic growth
  • DoD Mandates / Energy Security
    • Elimination of fuel requirement: reduces vulnerability in times of conflict or fuel shortages.
    • Test facility helps meet DOD requirement to secure 25% of power needs from renewable sources by 2025 as required in the FY07 Defense Authorization Act.
  • Department of Energy Program Goals
    • Research of advanced and more efficient wave energy concepts – accelerates test center goals.
    • Demonstration of domestically developed wave energy technologies.
    • Can help satisfy DOE program goal of Research & Demonstration of marine renewables.
mhk potential for job creation commercial exports
MHK Potential for Job Creation & Commercial Exports
  • Roadmap establishes goal of at least 15 GW installed capacity in U.S. waters by 2030.
  • Goal would support creation of up to 36,000 jobs across the U.S. for fabrication, installation, operations and maintenance of MHK devices by 2030.
  • U.K estimate predicts that the British marine energy sector could be worth £76 billion to the national economy and support 68,000 jobs by 2050.

Oregon Iron Works has the skilled workforce ready to build what others envision. Ocean renewable energy is a key growth industry that allows us to diversify our business while we continue to grow and create new green jobs right here in the United States.
