Perth wave energy project moves ahead

perthAUSTRALIAN company Carnegie Wave Energy is two steps closer to completing the country’s first commercial, grid-connected wave energy project.
Carnegie has announced the completion of pile foundations, which are due to be installed in the fourth quarter of this year.
The foundation installation vessel, Ensung, was delivered to the Australian Maritime Complex in Henderson, WA, and will be fitted out in coming weeks to prepare for installation.
Based on Garden Island in WA, the Perth wave energy project will supply clean energy to the HMAS Stirling naval base.
The Federal Government has contributed $13.1 million towards the project through the Australian Renewable Energy Agency’s (ARENA) Emerging Renewables program.
Furthermore, the WA Government was supporting the project through its Low Emissions Energy Development (LEED) fund with $7.3 million, and the Clean Technology Innovation Program was supplying Carnegie with $1.27 million for the desalination pilot.
To mark the milestone of completing the pile foundations, the company received $387,810 from the WA and Federal governments under the LEED and ARENA programs.
The project will utilise the company’s CETO wave energy technology which operates underwater. Submerged buoys tethered to seabed pump units move with the passing waves and drive the pumps, which pressurise water delivered onshore by a subsea pipe.
Once onshore, the water is used to drive hydroelectric turbines and can be used to supply a desalination plant.
