PORT KEMBLA, Australia -- Australia's cities are drought-parched and its desert outback drenched by floods, but climate change has not yet killed the country's famed surf beaches, or their promise of clean eco-power.
Australia's first commercial wave-generated power station will in weeks begin supplying homes south of Sydney with electricity and fresh drinking water, courtesy of the sea.
"The energy in waves is the densest of any natural sources of energy. It's pretty much always there and it doesn't go away like sun and wind do," John Bell, the Chief Finance Officer from station developer Energetech told Reuters.
Lying anchored just 100 metres (yards) off a popular surf beach near Wollongong, a city of around 200,000 people just south of Sydney, the 485-tonne plant will power 500 homes along the local grid.
Electricity is generated when waves wash into a funnel facing the ocean, driving air through a pipe and into a turbine capable of pumping 500kw of clean power each day into the local grid.
The A$6 million ($4.7 million) floating plant, built to withstand a 1-in-100 year storm, can also desalinate 2,000 litres of drinking water each day for almost as many homes as it powers.
"Our production units will be producing one million litres of water each day and we can produce at very low cost," Bell said.
The costs of power from the plant ranged below 10 cents per kilowatt of electricity and under A$1 per 1,000 litres of water.
The Portland plants, floating like an ocean-bound wind farm, would produce 10 megawatts, enough for around 15,000 homes.
Sounds pretty good.
