Carnegie Clean Energy CETO 6
The CETO, currently on the 6th design variant, is a submerged point absorber. A submerged steel buoy is anchored to the seafloor and the buoyancy of the buoy is used to drive a hydraulic pump. The high pressure hydraulic fluid is used to drive a generator (located inside the buoy) to generate electricity. The power is delivered back to shore through subsea cables to power desalination plants as well as for export into the grid. The mooring and foundation is separate from the power cable infrastructure. The CETO 6 design has a buoy that is roughly 20 m in diameter and is rated for 1.5 MW generation capacity.
While plans to deploy a prototype of the CETO 6 at the Wave Hub test site in the UK, and later in Albany, Australia, have been cancelled, Carnegie remains engaged in improving the design of this technology and exploring partnerships for future deployments. As of August 2024, the company is actively seeking an International Electrotechnical Commission’s Renewable Energy System (IECRE) certification through Lloyd’s Register (LR), an IECRE accepted renewable energy certification body (RECB) with a scope in marine energy. Obtaining the certification will consist of an assessment by LR in accordance with IEC and ISO technical standards to verify and validate the CETO WEC technology.
