What is CETO

NAMED AFTER A GREEK SEA GODDESS

CETO offers the potential to revolutionise power and water production globally. CETO harnesses the enormous renewable energy present in our ocean’s waves and converts it into two of the most valuable commodities underpinning the sustainable growth of the planet; zero-emission electricity and zero-emission desalinated water.

The CETO system is different from other wave energy devices as it operates under water where it is safer from large storms and invisible from the shore. The fully submerged buoys drive pumps and generators that are contained offshore, within the buoy itself, with power delivered back to shore through subsea cables to power desalination plants as well as for export into the grid.
 

CETO TECHNOLOGY CHARACTERISTICS INCLUDE:

1
The Buoyant Actuator (BA)

The Buoyant Actuator (BA): interacts with the ocean waves to capture energy from their passing. Manufactured from steel to withstand the large forces acting on it. The Buoyant Actuator houses all the electrical generation equipment inside the device.

2
Pump

A single acting hydraulic pump, which converts the motion of the Buoyant Actuator into fluid pressure which is used to generate electricity inside the Buoyant Actuator.

3
Foundation

A drill and grout pile is inserted into the sea floor, the CETO device reacts against this to cause the pump to extend as well as stopping the device floating away.

4
Tether

Tether: A Large synthetic , marine grade rope with specialised terminators, connects the pump to the foundation connector.

5
Foundation Connector

CETO’s use a highly specialised Foundation Connector which allows the device to be recovered without the need to deploy divers.

6
BA Umbilical Connector

Electricity generated inside the BA is delivered to the umbilical through the BA Umbilical Connector.  This specially designed connector allow wet-mating of the electrical system while at sea.

7
Mid-Water Arch

This device ensures that the umbilical does not become tangled or bend too far as the BA moves in response to passing waves

8
Umbilical

The umbilical connects the CETO device to the local grid, so that clean emission free energy can be delivered to the local grid in the most efficient means possible.

ADVANTAGES OF CETO

  •  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, onshore & offshore power generation
  • Storm Survivability – fully submerged & energy dampening system
  • Security – provides emissions free sustainable energy and water security to countries & islands
  • Scalable – modular array design
  • Minimal – environmental impact, co-exists with marine life.
  • Desalination – zero-emission freshwater & co-production possible
