CETO Technology

Named after a Greek sea goddess, CETO offers the potential to revolutionise renewable power production globally. CETO harnesses the enormous untapped energy present in our ocean’s waves and converts it into grid-ready electricity.


CETO is a unique, fully submerged, point absorber type wave energy technology. A submerged buoy sits a few metres below the surface of the ocean and moves with the ocean’s waves. This orbital motion drives a power take-off (PTO) system that converts this motion into electricity.

The CETO 6 design builds on intellectual property first lodged by Carnegie in 2013, incorporating on-board power generation and multiple moorings and power take-off modules. This associated US patent, granted on 6 November 2017, confirms the additional features as state of the art. These features boost power production and unit efficiency.


CETO  Technology Characteristics

  1. Converts ocean wave energy into zero-emission electricity
  2. Environmentally friendly, has minimal visual impact and attracts marine life
  3. Fully-submerged and operates in deep water, away from breaking storm waves and beach-goers
  4. Tens of thousands of hours of in-ocean operational testing
