On behalf of the Australian Government, the Australian Renewable Energy Agency (ARENA) has today announced $4 million in funding to Wave Swell Energy Limited to install a pilot-scale wave energy converter off the coast of King Island, Tasmania.

Topics: Tasmania energy

The $12.3 million project will involve the design, construction, installation and operation of the UniWave 200, a 200 kW wave energy device off the coast of King Island.

The project will also be integrated with the King Island microgrid operated by Hydro Tasmania, which received $6 million in ARENA funding in 2011 to demonstrate the integration of several renewable resources and energy management technologies.

The device will be partially submerged as it sits on the seabed and has an opening on one side to allow the movement of the waves in and out of the chamber.

Water rises and falls inside the chamber, causing the pressure of the air trapped above to change between negative and positive pressure. The pressure fluctuations force the air to pass through the turbine at the top of the chamber, generating electricity.
