Next generation of landmark Australian wave technology

The Australian Renewable Energy Agency (ARENA) has announced
$11 million funding to support the next vital step in Carnegie Wave Energy’s ground-breaking CETO technology.

ARENA chief executive officer Ivor Frischknecht said the funding would help Carnegie progress towards commercialisation of its CETO technology, which is set to significantly advance wave energy in Australia and throughout the world.

“The $46 million CETO 6 project represents the next generation of Carnegie’s landmark wave technology and is expected to deliver energy at approximately half the cost of CETO 5,” Mr Frischknecht said.

“CETO 6 also allows for offshore power generation, which could enable additional applications for the technology operating further from shore, in deep water.”

The units are large, fully submerged buoys, tethered to the ocean floor and designed to harness energy from the ocean’s waves. The larger size of the CETO 6 units is a key driver of lower energy costs, compared to the CETO 5 units.

“A single CETO 6 unit will be capable of generating up to 1MW – approximately four times the capacity of the CETO 5 units,” Mr Frischknecht said.

“This increased generation capacity, combined with improved efficiency, delivers reduced power costs and brings the technology closer to commercialisation.”

CETO 6 builds on knowledge gained from previous generations of the technology and aims to be cost-competitive with fossil fuels in certain markets when deployed in large-scale projects. As the technology approaches commercialisation, each generation requires a lower fraction of the overall project cost to be provided by government.

ARENA has said it is pleased to support this Australian-owned and globally deployed technology, which is yet to fully realise its job creation and export potential, according to Mr Frischknecht.

The project will deploy three CETO 6 units off the coast of Garden Island, Western Australia. It will generate up to 3MW grid-connected power for the HMAS Stirling Navy base, as part of Carnegie’s existing power supply agreement.

In addition to Australian Government funding received through ARENA’s Emerging Renewables Program, Carnegie has a five-year, $20 million loan facility from the Clean Energy Finance Corporation to support the
$46 million CETO 6 Project.
