21. Technology • Oceanlink Water goes up and down in the cavity pushing and pulling air through the turbine Prototype of 450 kW tested in Port Kembla (Aus) (2007)

22. Technology • Port Kembla (New South Wales, Australia): a Power Purchase Agreement (“PPA”) has been signed with Australian utility Integral Energy for the supply of electricity from the prototype 450kW unit.  This will be the first offshore wave energy company to be connected to the commercial grid (expected November 2007). • Portland (Victoria, Australia): in advanced permitting stage for the deployment of eighteen 1.5MW units, giving a total capacity of 27MW.  This will be the largest wave energy project in development in the world. • GPP (Namibia): a signed contract with GPP, part of the listed Southern African Utility SELCo for a 1.5MW unit.  Once this unit reaches its agreed performance criteria, it will be followed by a further 10 units, equivalent to 15MW. • South West of England Regional Development Agency (SWRDA, Cornwall, UK): a signed Letter of Intent (“LOI”) with SWRDA for a 5MW facility as part of the Cornwall Wave Hub. • Rhode Island (USA): a Memorandum of Understanding (“MOU”) with Rhode Island State authority for a 1.5MW unit, followed by a 15 to 20MW electricity generating facility off the mainland. • Hawaii (USA): a signed MOU with an island in Hawaii for up to 2.7MW.

23. Technology • Wavegen • Oscillating Water Column concept on-shore 500 kW prototype on Islay Island (UK) Source: Boyle, Renewable Energy, 2nd edition, 2004

24. Islay Island (Scotland) • Wave power density: • 25 kW/m • Length: • 20 m • Built in 2000 • Actual max power about 40% of predicted because of the sea floor shape
