  1. IEC TC 114 - Marine Energy: Wave, Tidal and other Water Current Converters IEC TC 88 Plenary Meeting Boulder, Colorado March 11-12, 2010 Chair IEC TC 114 Melanie Nadeau, P.Eng. , NRCan Secretary IEC TC 114 Danny Peacock, BSI

  2. Marine Renewable Energy MarineEnergy TidalRise & Fall Tidal/ocean Currents Waves Salinity Gradient Thermal Gradient • Water Currents/Hydrokinetic Energy • Submarine Geothermal

  3. Technology Maturity Tidal barrages Ocean waves & tidal currents technologies Salinity gradient technologies OTEC Technologies Mature technology, despite limited applications. Likely to have significant impact on local ecosystems Significant number of technologies being developed worldwide: some of these technologies are at or near full-scale development and undergoing sea trials; first ‘commercial’ technologies operational in 2008 Early stage R & D; demonstration prototypes operational Advanced stage of R & D

  4. Technology Maturity Source: Ref: Powertech Labs Task Report, 2007

  5. Tidal |Water Currents Horizontal Axis Turbines Vertical Axis Turbines Hydrofoils

  6. Wave Technologies Oscillating Water Column (OWC) Overtopping Devices Oscillating Bodies (Point Absorbers & Surge Devices)

  7. IEC TC 114 – Marine Energy • Fall 2007 – SMB approved the formation of a new Technical Committee (TC) 114 on Marine Energy: Wave, tidal and other water current converters • British Standards Institute (BSI), United Kingdom holds Secretariat Inaugural Meeting in Ottawa, CA on May 14-15, 2008 • 13 Member Countries with participating status (P-member), 7 Countries as observers (O-member) • Formal Liaisons established • TC 4 – Hydraulic Turbines • TC 88 – Wind Turbines • IEA – OES • EquiMAR

  8. Scope of IEC TC 114 To prepare international standards for marine energy conversion systems. The primary focus will be on conversion of wave, tidal and other water current energy into electrical energy, although other conversion methods, systems and products are included. Tidal barrage and dam installations, as covered by TC 4, are excluded.

  9. IEC TC 114 Standards • Standards produced by TC 114 will address: • System definition • Performance measurement of wave, tidal and water current energy converters • Resource assessment requirements • Design and safety requirements • Power quality • Manufacturing and factory testing • Evaluation and mitigation of environmental impacts

  10. Work Programme NWIP issued PT or WG established

  11. Operations • Meetings • Plenary – 1 per year (12 months +) • NWIPs proposed at plenary or via DCs • Country recent advancements • Programme of Work • Chairman Advisory Group (CAG) – PT/WG leaders • Face-to-Face (1/year) • Teleconference (2/year) • WG/PT Leaders & Members (79 experts) • Collaboration Tools • Teleconference/WebEX/Skype • Face-to-face • Invited experts

  12. Marine Energy Standards Map • Marine Energy Source (Tidal/Wave) • Environmental Assessment • Site Conditions Studies • Safety and Reliability Requirements Marine Energy Converter Utility Substation and Connection Electrical Power System • Mechanical Conversion • Blade • Gear Box • Hydraulics Bearings • Electrical Conversion • Generator • Static Power Converter • Low Power Generation • High Power Generation and Farms • Submarine Cable • Transformers • Switchgear • Monitoring, Protection and Control • Electrical Connections and Wiring • Structural Components • Foundation • Moorings • Materials • Coatings/Corrosion Protection • Converter Installation & Operation • Performance Measurements • Installation, Commissioning, and Decommissioning • Operation & Maintenance

  13. Various Technologies with Relevant Standards Wind Standards Distributed Generation Grid connection Underwater cabling, switchgear, and connection requirements Blade, bearings, and gearboxes can use similar design load analysis and testing as wind and hydro-electric turbines Offshore Standards Foundations & Mooring Offshore Materials Hydro-Electric Standards

  14. Global Wave Energy Resource Data from the ECMWF (European Centre for Medium-Range Weather Forecasts) WAM model archive -calibrated and corrected by OCEANOR against a global buoy and Topex satellite altimeter database.

  15. Global Tidal Energy Locations

  16. Costs of Energy Costs of energy generated by wave & tidal energy converters deployed in initial farms (Source: Carbon Trust, 2006) 1 GBP = 1.8 CAD Cost estimates for ocean technologies have high uncertainty, given that few devices have actually been manufactured at full-scale and tested under normal operating conditions.

  17. Future Costs of Energy Cost of energy as a function of installed power (Source: Carbon Trust, 2006): Optimistic estimate Initial cost $ 39c/kWh Learning curve 15% 1 GBP = 1.8 CAD Pessimistic estimate Initial cost $45c/kWh Learning curve 10%
