CETO Wave Energy Eystem
The CETO wave power converter is the first unit to be fully-submerged and to produce high pressure seawater from the power of waves. By delivering high pressure seawater ashore, the technology allows either zero-emission electricity to be produced (similar to hydroelectricity) or zero-emission freshwater (utilising standard reverse osmosis desalination technology). It also means that there is no need for undersea grids or high voltage transmission nor costly marine qualified plants. CETO units are fully submerged and permanently anchored to the sea floor meaning that there is no visual impact as the units are out of sight. This also assists in making them safe from the extreme forces that can be present during storms. They are self-tuning to tide, sea state and wave pattern, making them able to perform in a wide variety of wave heights and in any direction. CETO units are manufactured from steel, rubber and hypalon materials, all proven for over 20 years in a marine-environment.

Advantages: The best wave energy sites in the world receive consistent swell. CETO operates across a variety of wave heights making CETO a base load renewable energy option. • Wave energy is a renewable, zero-emission source of power. • 60% of the world live within 60km (40 miles) of a coast, removing transmission issues. • As water is approximately 800 times denser than air, the energy density of waves vastly exceeds that of wind dramatically increasing the amount of energy available for harvesting. • Waves are predictable days in advance making it easy to match supply and demand. (Wind is predictable hours in advance at best.) • CETO sits underwater, moored to the sea floor, resulting in no aesthetic impact. • CETO units are designed to operate in harmony with the waves rather than attempting to resist them. This means there is no need for massive steel and concrete structures to be built. • CETO wave farms will have no impact on popular surfing sites as breaking waves equate to areas of energy loss. CETO wave farms will operate in water deeper than 15 metres in areas where there are no breaking waves. • CETO units attract marine life. • CETO is the only wave energy technology that produces fresh water directly from seawater by magnifying the pressure variations in ocean waves. • CETO contains no oils, lubricants, or offshore electrical components. CETO is built from components with a known subsea life of over 30 years. • Wave energy can be harnessed for permanent base load power and for fresh water desalination. The ratio of electrical generation to fresh water production can be quickly varied from 100% to 0% allowing for rapid variations in power demand. • CETO uses a great multiplicity of identical units each of which can be mass produced and containerised for shipping to anywhere in the world.
