CETO is designed to be a simple and robust wave technology. {{As of|2016|January}} CETO is claimed to be the only ocean-tested wave-energy technology globally that is both fully submerged and generates power and or desalinated water onshore. The CETO technology has been independently verified by ] (EDF EN) and the French naval contractor DCNS.<ref name="carnegiewave">Carnegie Wave Energy, 2011.

CETO harnesses the untapped energy present in ocean waves and converts it to grid ready electricity. The device is fully submerged below the water surface and intended to be deployed in an array for large scale generation of electricity.
Sitting a few meters below the ocean's surface, the device is anchored to the seabed and is designed to be simple and robust wave technology. As the waves pass over the device, the submerged buoy moves with the waves. This orbital motion drives a power take off (PTO) system that converts the motion into electricity.

CETO Wave Technology is a point absorber type - wave energy device owned by Carnegie Clean Energy (www.carnegiece.com). Inspired by the Greek Ocean Goddess Ceto. Carnegie Clean Energy is currently in development of the CETO 6 device. CETO harnesses the untapped energy present in ocean waves and converts it to grid ready electricity. The device is fully submerged below the water surface and intended to be deployed in an array for large scale generation of electricity.

Sitting a few meters below the ocean's surface, the device is anchored to the seabed and is designed to be simple and robust wave technology. As the waves pass over the device, the submerged buoy moves with the waves. This orbital motion drives a power take off (PTO) system that converts the motion into electricity.

Technology

CETO 6

The current CETO 6 has incorporated learnings from previous devices and deployments to further advance the technology, CETO 6 varies significantly from CETO 5 in having a larger buoy, and multiple anchors and power take off units. With the electrical generation onboard and the power being transferred to shore by an electrical cable.

CETO 5

A previous prototype of CETO that was driven by a hydraulic system. The submerged Buoys are moved by the ocean swell, driving pumps that pressurize seawater delivered ashore by a subsea pipeline. Once onshore, the high-pressure seawater is used to drive hydro-electric turbines, generating electricity. The high-pressure seawater can also be used to supply a reverse osmosis desalination plant, producing freshwater. Some historic conventional seawater desalination plants are large emitters of greenhouse gases; this is due to the amount of energy required to drive the grid-connected pumps that deliver the high-pressure seawater to reverse osmosis membranes for the removal of the salt.

Projects

EuropeWave

Carnegie Clean Energy is involved in the EuropeWave PCP Programme through its wholly owned subsidiary CETO Wave Energy Ireland. Currently in phase 2 of the programme aimed at advancing wave energy technologies for commercialization.

Phase 2 includes front end engineering design and further tank testing leading to open water trials in phase 3. Successful advancement to Phase 3 will initiate a scaled prototype of the CETO device for deployment at either BiMEP in the Basque Country, Spain, and EMEC in Orkney, Scotland.

Perth Wave Energy Project (PWEP)

The Perth Wave Energy Project (PWEP) involved the design, construction, deployment and operational performance evaluation of a grid-connected commercial-scale wave-energy demonstration project, at Garden Island Western Australia. The facility consisted of multiple submerged CETO units in an array, subsea pipeline(s) to shore, hydraulic conditioning equipment, and an onshore power generation facility.

A multi megawatt system was connected to the grid, with all the electricity being bought to power HMAS Stirling naval base. Three fully submerged buoys were anchored to the seabed and transmitted the energy from the ocean swell through hydraulic pressure onshore; to drive a generator for electricity, and also to produce fresh water. Funding requirements included the full decommissioning of this project for successful validation.

Other wave energy and CETO characteristics

  • Wave energy is a renewable, high availability source of power.
  • About 60% of the human population lives within 60 kilometers of a coastline, minimising transmission issues.
  • Since water is about 800 times denser than air, the energy density of waves exceeds that of wind and solar, increasing the amount of energy available for harvesting.
  • Waves are predictable in advance, making it easier to predict mismatches between supply and demand.
  • CETO units operate in deep water, away from breaking waves, meaning there is minimal impact on popular surfing sites.
  • CETO units are designed to operate in harmony with the waves. This means, apart from anchor points, there is no need for massive steel and concrete support structures to be built.
