Perth wave energy project producing power and fresh water
Carnegie Wave Energy based in Perth is a world leader in wave energy technology. In 2014 the company began deployment of three wave energy converters at the Garden Island naval base off the coast near Perth. Large buoys rise and fall with passing waves. Each is tied by rope to the sea floor. As waves pass, the buoys rise, the ropes tighten and extremely high pressure is created in a water-based fluid. This is piped to shore where the pressure powers water desalination and the production of electricity. This technology, known as CETO, has application for small coastal towns and remote islands where oil or diesel is often used in generators. The Perth project is the first demonstration of a complete grid-connected CETO system anywhere in the world.
