The $31 million ‘Perth Project’ will see the first CETO wave energy generation plant, located on Garden Island, up and running by the end of next year.
Carnegie Wave Energy, a Perth-based public company, is the owner of this unique technology which delivers desalinated water and zero emission power.
The Garden Island plant will have the capacity to generate 2 megawatts of electricity – enough to power 1,000 homes – and upon its completion will be used to power the island’s naval base.
Carnegie describe the CETO technology in the following manner:
“CETO is a fully submerged, pump-based technology whereby a submerged Buoyant Actuator moves with the energy of the ocean’s waves, 1-2 metres below the surface of the ocean.
“The Buoyant Actuator is attached to a pump via a tether, and the entire system is moored to the seabed.
“As the Buoyant Actuator oscillates with the wave motion, it allows the pump to extend and contract propelling high-pressure fluid ashore via a subsea pipeline.
“The high-pressure fluid then powers an off the shelf hydroelectric turbine to generate clean renewable electricity.”
Because of its docile, submerged characteristic CETO technology has minimal visual impact, is safe from storms and to people in the water, and also helps attract marine life.
