Carnegie - 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.
- Converts ocean wave energy into zero-emission electricity
- Environmentally friendly, has minimal visual impact and attracts marine life
- Fully-submerged and operates in deep water, away from breaking storm waves and beach-goers
- Tens of thousands of hours of in-ocean operational testing
- No Visual Impact – fully submerged
- Developed & Proven – over 10 years with onshore, wave tank and tens of thousands of hours of in-ocean testing
- Flexible -operates in variety of water depths, swell directions, tides & seafloor conditions
- Storm Survivability – fully submerged & extreme wave mitigation system
- Security – provides emissions free sustainable energy and water security to countries & islands
- Scalable – modular array design
- Clean – minimal environmental impact, co-exists with marine life.
- Desalination – zero-emission freshwater co-production allows pseudo energy storage
Carnegie has been operating its unique, purpose built private Wave Energy Research Facility since 2005. It is an invaluable asset and an enabler of Carnegie’s rapid prototyping capability. Industry participants are also invited to use the facility.
Carnegie’s Wave Energy Research Facility is located at Fremantle in Western Australia and consists of an integrated onshore and offshore test facility. Onshore, Carnegie carries out high cycle, accelerated testing of CETO components to test performance and to increase understanding of wear and routine maintenance.
Offshore, Carnegie holds a lease over an ocean area that is used for ongoing in-sea prototype and pilot plant testing in a subdued wave energy “nursery” site allowing rapid testing and recovery. Carnegie is possibly the only wave energy company in the world to have exclusive access to such a Wave Energy Research Facility.
Various external organisations have tested their equipment at this site, including subsea positioning, corrosion monitoring and underwater PZT camera systems.
Carnegie’s Wave Energy Research Facility:
- Offshore lease area located 300 metres from onshore facility with a nominal depth of 7 metres
- Offshore test site connected via pipeline, hydraulic hoses, power and instrumentation cables to onshore facility
- Real-time technology and environmental monitoring including offshore CCTV, SCADA system and wave buoy
- Onshore facility allows high frequency, in-house testing of components prior to deployment
- Historical wave data
Carnegie’s CETO Intellectual Property portfolio consists of seven patent families and more than 90 patents and patents pending along with various trademarks.
An Independent Expert’s Report completed by intellectual property specialists, Global IP Services, described the investment made in protecting the CETO intellectual property as having “…created significant IP barriers to entry, and provides Carnegie…with a strong, global capacity to leverage its CETO IP and successfully commercialise this technology…”
Carnegie owns the global Intellectual Property & Development Rights for the CETO technology and will continue to generate and protect new IP as CETO continues to mature. This IP, along with Carnegie’s unique development capability and CETO knowledge and experience, creates a significant competitive advantage which will allow Carnegie to tap into the vast global wave energy resource.
