Hot Rocks
Spurred by high electricity prices and a drive to reduce Australia's reliance on coal, several companies are looking to harness hot rock temperatures of up to 300 degrees Celsius to provide renewable energy.
Geodynamics has completed the drilling of its two 4.5 kilometre deep Habanero wells – named after the world's hottest chili variety – and is now testing geothermal levels in the surrounding rock to establish a proven reserve level.
To generate electricity, water is pumped down through a well at extremely high pressure to widen existing rock fractures. This increases their capacity to super-heat large volumes of water, which are then transferred to a nearby geothermal power station to heat liquids with a low boiling point to generate steam and then electricity.
See the display at the Innamincka Hotel for up to date information on this revolutionary project.
