For solar energy, achieving “supercritical†steam is a major breakthrough, meaning that the world’s most advanced power plants can be driven in the future, and current power plants rely on coal or natural gas for power generation. The Australian Commonwealth Scientific and Industrial Research Organisation (CSIRO) uses solar energy to achieve pressurized “supercritical†steam, bringing the steam temperature to its highest ever value. This major technological achievement enables the cost competitiveness of solar thermal power plants to compete with fossil fuels. CSIRO Energy Director Dr. Alex said: “This is a milestone in changing the rules of the game for the renewable energy industry. It seems that beyond the sound barrier, this change in step proves that solar energy has the potential to compete with the peak performance of fossil fuel sources.†Dr. Alex said: "At present, about 90% of Australia's electricity is produced using fossil fuels, and only a few power stations are based on more advanced 'supercritical' steam. This groundbreaking research shows that future power plants make use of free, zero Emissions of solar energy can achieve the same effect.†According to a report recently organized by the Physicists Organization Network, this demonstration project, which brings breakthrough progress to solar power generation, uses solar radiation heating to pressurize water. “Supercritical†solar steam reaches a pressure of 23.5 MPa per unit area, and the temperature reaches 570 degrees Celsius. The breakthrough was made at the CSIRO Energy Center in Newcastle, New South Wales, home to the Australian Low Emissions and Renewable Energy Research. The center includes two solar thermal-thermal test power plants, with more than 600 heliostats, directly facing the two solar collectors covered with solar receivers and turbines. Commercial solar thermal power plants around the world currently use subcritical steam and operate at similar temperatures but at lower pressures. If these plants can reach the state of supercritical steam, it will help improve efficiency and reduce the cost of solar power generation. The research project was supported by the 5.68 million U.S. dollars provided by Australia's Renewable Energy Agency (ARENA) and was completed in cooperation with Argengo Solar, the world's largest supplier of solar thermal power. CSIRO is also developing advanced solar energy storage to provide solar power at any time of day or night. Silicate can be used in many industries, it include different kinds of silicate, such as: Potassium Silicate, Potassium Sodium Silicate , Sodium Silicate and so on. Potassium silicate & Potassium sodium silicate with glassy lump and liquid mainly are used for welding industry, also can be used for Agriculture, oil drilling field. Powdery Instant Potassium Silicate is white powdery substance, can fast dissolve in water, resistant to cold and good uniformity. It is a special foamed alkali convenient to be used, transported and stored. Molecular formula: K2O·nSiO2·H2O, n varies with the specification the uses. Powdery Instant Potassium Silicate has better solubility and higher adhension compared with powdery instant sodium silcate and is widely used as adhesive in fireproof material, as auxiliary in drilling liquid of oil field and other special fields.
