, Cloncurry, Australia, a
sun-drenched town in Australia’s north hopes to use only solar power in two years after being chosen as the site for a solar thermal power station.
Remote Cloncurry, which boasts recording Australia’s hottest day, would be able to generate electricity on rare cloudy days and at night from the station, which runs off heat stored in graphite blocks.
The Queensland state government said on Sunday it would build the A$7 million ($6.5 million), 10-megawatt power station as part of a push to make Cloncurry one of the first towns to rely on solar power alone.
“The town of Cloncurry has long claimed the title of having recorded Australia’s hottest day — 53 degrees (Celsius) in the shade in 1889, so I reckon we’re on a winner,” Queensland Premier Anna Bligh was quoted as saying by Australian Associated Press.
Solar thermal power differs from photovoltaic panels that make power directly.
Instead, 8,000 mirrors will reflect sunlight onto graphite blocks. Water will be pumped through the blocks to generate steam which generates electricity via turbines.
Heat stored in the graphite produces steam well after the sun goes down, allowing electricity generators to keep running at night.
