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

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):
