An Australian water solutions company has announced the development of the first ever wave-powered desalination technology, which promises to make the desalination process fully sustainable.

Perth-based Carnegie Wave Energy said that it will not only create a unique desalination plant but that it will also be the first company to produce both electrons and fresh water through a wave energy project.

The news was announced shortly after Carnegie entered into a partnership with U.S.-based Water Corporation, which will back up a trial desalination project to be built over the next few months. The pilot plant will be located on Garden Island, Western Australia, which is also home to Australia's biggest naval base. It will be built alongside Carnegie's Perth Wave Energy Project, which integrates reverse osmosis desalination with the Perth Project's wave energy infrastructure, currently under construction on the island.

Water Corporation is one of the pioneers in desalination technology. Its 2006 Kwinana facility was the first large-scale desalination plant in Australia and the company is currently working on a new plant at Binningup. The combined capacity of these two plants will be 100 billion liters of freshwater, or about 50 percent of Perth's drinking water needs.

According to Sue Murphy, CEO of Water Corporation, desalination is of major importance for the city's long-term water supply plan and the company's collaboration with Carnegie will result in an innovative way of producing drinking water without any carbon emissions.
