Carnegie Wave Energy Ltd. announced plans to build a commercial-scale wave-energy plant at Garden Island, 31 miles south of Perth, Australia.
The 5-MW plant will be completed by 2011. The first of 25 to 30 units will be installed next year. The plant is being built to assess the feasibility of using Carnegie’s wave-energy technology to power a naval base near Exmouth, north of Perth.
The feasibility study will examine several factors, including wave resource, environmental values, geophysical conditions and connectivity to the naval base.
Carnegie’s technology consists of a series of underwater buoys tethered to pump units bolted to the seabed. The buoys drive the pumps, which deliver high-pressure water via pipeline to hydroelectric turbines on shore.
