Wave power in Australia

[3] 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 changes in the depth of the water column changing the pressure in the balloons.

A series of large buoys is tethered to piston pumps anchored in waters 15 to 50 metres (49 to 164 ft) deep.

The rise and fall of passing waves drives the pumps, generating water pressures of up to 1,000 pounds per square inch (psi).

Carnegie's first commercial wave farm is due to be completed on Garden Island, near Perth, Western Australia, by mid 2014.

[7][8] It is a 200 kW unit which is connected to the island's existing microgrid, which also utilises like wind, solar, battery and diesel.
