Converting Wave Energy into Zero-Emission Electricity and Desalinated Water

The CETO uses wave energy for generating large amounts of renewable energy.

Harnessing the vast amounts of renewable energy from the depths of the ocean has taken a giant leap forward with this revolutionary technology from Carnegie Energy.

The main benefits of wave energy come from the reliability and predictability of wave activity as well as 60% of the world population living within 60 kilometers off a coast making the proximity of wave energy sites applicable to its end users.

Based in Australia, Carnegie Energy has produced the first wave power converter that is fully submerged producing high-pressure water using wave power.

The CETO utilizes standard reverse osmosis desalination technology to produce zero-emission freshwater and zero-emission electricity.

Named after a Greek sea goddess, these CETO units are fixed to the seafloor making them safe in extreme weather and tucked away from the skyline.

A unique capability of CETO technology is its desalination capabilities using reverse osmosis without greenhouse gas emissions, with many wave energy technologies bringing electricity under high voltage to shore. This is not the case with CETO, allowing them to make a massive saving from having to convert energy.

Just to put the energy savings perspective the estimated energy loss of a coal-powered desalination plant is approximately 75% whereas, a CETO desalination plant has an estimated energy loss of only 8%.

The CETO 5 is an enhancement from past generations with a larger diameter increasing from seven meters to eleven, which has a major influence on power input. Improvements in the hydraulics combined with a larger diameter have allowed for a rated capacity of approximately 240kW.

From its initial designs in 1999 to the first prototypes in 2003, the CETO is now on its latest generation, the CETO 5 Unit. Carnegie Energy now operates projects across the globe in Perth, North America, and Europe.
