Australia uses the motion of the ocean to generate zero-emission electricity.


It’s not the size of the buoy that counts. It’s the motion in the ocean.

Actually, both are pretty important. At least, they are when it comes to Australia’s new CETO 5 system: “The first array of wave power generators to be connected to an electricity grid in Australia and worldwide” according to Australian Renewable Energy Agency CEO Ivor Frischknecht. As of February 18, that system has been channeling clean, efficient, zero-emission energy into Australia’s power grid, providing electricity to the country’s largest naval base.

CETO 5, named for the ancient Greek sea goddess, is part of the “Carnegie Perth Wave Energy Project,” a multimillion dollar initiative built to demonstrate the commercial viability of a large-scale wave power. The system is already turning heads both for the energy it produces, as well as the pollution it doesn’t.

CETO 5 (the fifth iteration of the CETO technology) is a modular array of three, entirely-submerged 240 kW buoys and water pumps. As oceanic waves move the buoys, they in turn activate the pumps, pushing pressurized water through power turbines, while simultaneously feeding into a desalinization system.
