Oceanlinx is trialling a wave energy system at Port Kembla - Thousands of air filled balloons are submerged under water and energy is collected by the friction of water rubbing against the balloons. Carnegie Corporations are seeking approval for the development of three projects in Australia. In Western Australia they are refining a method of using energy captured from passing waves to generate high-pressure sea water. This is piped onshore to drive a turbine and to create desalinated water. A series of large buoys is tethered to piston pumps anchored in waters 15 to 50 metres deep (49 to 131 feet). The rise and fall of passing waves drives the pumps, generating water pressures of up to 1,000 pounds per square inch (psi). The company is looking to have a 50 MW demonstration project finished within the next four years. The company is also seeking to develop several wave power projects in Victoria.
A wave power project at Douglas Point, South Australia and another funded by the State government and Carnegie that will produce 50MW of power is set be developed near Albany W.A.
BioPower Systems is developing its bioWAVE system anchored to the seabed that would generate electricity through the movement of buoyant blades as waves pass, in a swaying motion similar to the way sea plants, such as kelp, move. It expects to complete pilot wave and tidal projects off northern Tasmania this year.
