Qinghai Solar Thermal Energy Storage Technology Breaks New Ground

On May 5th, good news came from the Provincial Department of Science and Technology: After four years of unremitting efforts by the researchers, our province has tackled the development of high-temperature heat storage technology and equipment for solar thermal power generation and created China’s first solar energy with molten salt and heat storage. Thermal power station.

It is understood that this breakthrough in science and technology comes from the Provincial Department of Science and Technology organized by the implementation of major scientific and technological projects in Qinghai Province, "solar thermal power in high temperature heat storage technology and equipment development" and "megawatt solar thermal power absorber key technology development." After nearly 4 years of research and development, the project has achieved synergy with the research team outside the province to overcome the development of high-temperature heat storage technology and equipment in solar thermal power generation, and succeeded in establishing the 10MW tower-type solar thermal power station at Delingha. Developed a tower-type light-hot-hot-salt heat storage system, with an effective heat storage time of more than two hours, a temperature drop of less than 10 degrees Celsius in a molten salt tank within 24 hours, and a single set of medium-high temperature molten salt heat storage system with a total capacity of 5 MWh The normal operation has become China's first solar thermal power station with molten salt heat storage. At present, scientific research projects have passed the acceptance, and the expert group believes that the results have reached the domestic leading level.

The implementation of the project marked a further step in the development of the tower-type solar thermal energy storage system with independent intellectual property rights in China, which is of great significance for the large-scale promotion of solar thermal power generation in the province and the surrounding areas.

Workstation Sink

A Workstation sink is a sink with a mechanism built in to the front and back sides of the bowl to allow accessories to sit on the step or ledge, affording the user to prepare meals on the sink instead of on the countertop. The intent behind the design is to speed up the process of food preparation and clean-up.
