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. Power can be generated either offshore or onshore. The fully submerged buoys can drive seabed pump units to deliver high pressure fluid onshore via a subsea pipe to standard hydroelectric turbines, generating zero-emission electricity. The high-pressure water can also be used to supply a reverse osmosis desalination plant, replacing or reducing reliance on greenhouse gas-emitting, electrically-driven pumps usually required for such plants.  Alternatively, the movement of the buoys can drive pumps and generators that are contained offshore, within the buoy itself, with power delivered back to shore through subsea cables.

CETO Technology characteristics include:

  • Converts ocean wave energy into zero-emission electricity and desalinated water.
  • Environmentally friendly, has minimal visual impact and attracts marine life.
  • Fully-submerged in deep water, away from breaking waves and beachgoers, and unaffected by storms.
