Last week the first commercial-scale grid connected wave energy array was switched on in Perth, Australia. Carnegie Wave developed a technology to drive pumps at the sea bed by the up and down movement of great buoys near the water surface. These pumps feed high pressure water onshore to a power station and desalination plant, not only providing energy but also fresh water. One unit was measured to have 240kW peak capacity during testing, but the company is already working on a next generation of converters to make it more cost-effective.
