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
Marine Renewable Energy Marine Energy Tidal Rise & Fall Tidal/ocean Currents Waves Salinity Gradient Thermal Gradient Water Currents/Hydrokinetic Energy Submarine Geothermal
Technology Maturity 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 Tidal barrages Ocean waves & tidal currents technologies Salinity gradient technologies OTEC Technologies
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 IEC TC 114 – Marine Energy Inaugural Meeting in Ottawa, CA on May 14-15, 2008 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
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.
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

Costs of Energy Costs of energy generated by wave & tidal energy converters deployed in initial farms (Source: Carbon Trust, 2006) 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. 1 GBP = 1.8 CAD
Future Costs of Energy Optimistic estimate Initial cost $ 39c/kWh Learning curve 15% Pessimistic estimate Initial cost $45c/kWh Learning curve 10% Cost of energy as a function of installed power (Source: Carbon Trust, 2006): 1 GBP = 1.8 CAD
