The design is a common solar power tower design. An array of motorised heliostat mirrors reflects sunlight to the summit of a tower. The summit houses a receiver, which is heated by the concentrated sunlight. A total of 54 towers of 18 m (59 ft) high will be constructed.
An important advantage of solar thermal energy is the possibility of storing heat for later use. In this way, the plant can also produce electricity at night or on overcast days. A common method is the storage of molten nitrate salt in large tanks; this is the technology used in Solar Tres Power Tower.
The Cloncurry plant uses the new technology of heat storage in blocks of purified graphite. The blocks are placed on top of the tower. The concentrated light on the receivers of the towers is directly transported to these blocks. The heat for electricity production is drawn from the blocks (i.e. there is no direct heat transport from the receiver).

... The smoke-sauna stove is also used with a sealed stone compartment and chimney (a heat storage-stove) which eliminates the smoke odour and eye irritation of the smoke sauna ... A heat storage stove does not give up much heat in the sauna before bathing since the stone compartment has an insulated lid ... This heat is soft and clean because, thanks to combustion, the stove stones glow red, even white-hot, and are freed of dust at the same time ...
... Calcium nitrate together with Potassium and Sodium nitrate is used to absorb and store energy in the Concentrated Solar Power plants ... It can be used as a heat transfer fluid instead of the thermal oil ...
... is the first commercial solar plant in the world with central tower receiver and molten salt heat storage technology ... production of 110 GWh/year and a 15-hour storage capacity in the absence of solar radiation ... The inclusion of the molten salt heat storage system allows the plant to produce electricity even when there is no solar radiation ...
Famous quotes containing the words storage and/or heat:
“Many of our houses, both public and private, with their almost innumerable apartments, their huge halls and their cellars for the storage of wines and other munitions of peace, appear to me extravagantly large for their inhabitants. They are so vast and magnificent that the latter seem to be only vermin which infest them.”
—Henry David Thoreau (18171862)
“The Soul rules over matter. Matter may pass away like a mote in the sunbeam, may be absorbed into the immensity of God, as a mist is absorbed into the heat of the Sunbut the soul is the kingdom of God, the abode of love, of truth, of virtue.”
—Ralph Waldo Emerson (18031882)
