The Qinghai Salt Lake Research Institute of the Chinese Academy of Sciences disclosed on the 7th that the research team of the institute has made new progress in the performance study of nitrate-smelting salt storage materials in the salt lake, providing more possibilities for the application of salt lake nitrate molten salt energy storage materials in CSP.
As a new energy technology, solar thermal power generation technology is the main technical field for China to promote the 'energy saving and efficiency improvement' strategy. As the core technology of solar thermal power generation, the selection and preparation of thermal storage materials is especially important.
According to the Qinghai Salt Lake Research Institute of the Chinese Academy of Sciences, molten salt (including molten salt of nitric acid) has become the first choice for CSP energy storage materials due to its large heat capacity, low viscosity, low vapor pressure and wide temperature.
It is understood that the research team of the Institute of Salt Lake Resources Chemistry of the Institute, using the salt lake resources as raw materials, has further improved its preparation by preparing a low-melting ternary molten salt energy storage material and introducing carbon nanotubes into the nitrate system. Thermal conductivity. This not only provides a theoretical basis for the preparation of nitrate molten salt heat storage materials, but also opens up more possibilities for its application in CSP.
China National Grid Qinghai Electric Power Company statistics show that the current installed capacity of Qinghai Power Grid reached 27.78 million kilowatts, of which solar energy, wind power installed capacity reached 12.08 million kilowatts, is the province's largest power supply.
The salt lakes in Qinghai Province are rich, reducing the production cost of related phase change energy storage materials, which will help promote the scale development of solar energy and the optimization of energy structure adjustment.
