Aussie innovation yields electricity, carbon-free desalination
The innovative system relies on a series of buoys harnessed to pumps below the ocean’s surface at depths of 15 to 50 meters. As the buoys rise and fall with each passing wave, they power the pumps and push water through on-shore turbines to produce electricity. The pressure of the incoming water also pushes the water through a membrane that removes salt and other minerals, producing fresh water without the typical desalination plant’s high electricity demands.
Carnegie says the CETO technology (named for the sea monster of the same name in Greek mythology) offers numerous advantages over other wind- and wave-energy systems. The benefits include:
* The reliability of wave energy, which is more predictable than wind energy;
* Zero offshore aesthetic impact, as the wave-driven pumps are moored underwater;
* No interference with marine life or human activities like surfing;
* No offshore electrical components, meaning pump units can last for more than 30 years; and
* A system that uses multiple identical units that are easy to mass-produce and ship anywhere.
