Waste Management & Environment
October, 2007 Page: 9
The WA Water Corporation has dangled a carrot in front of companies touting novel renewable energy technologies, calling for bids from them to supply 20 per cent of the power to the planned Southern Seawater desalination Plant. Some 160GWh is to come from tried and tested renewable energy sources, such as wind farms, but the authority wants up to 40GWh per year from technology not yet commercially proven on a large scale.
Also, Carnegie Corporation has opened a $10 million share float to commercialise its wave power technology, which it's pitching as a green way to pump water for desalination plants. The CETO technology is an array of submerged buoys attached to seabed pump units. As they move with the motion of the waves they drive the pumps, which pressurises and pipes seawater. Carnegie hopes to raise $6-8 million to take it to commercial-ready status.
