The first international 10MW high temperature thermal storage experimental platform was successfully debugged

Recently, the world's first 10MW high-temperature thermal storage experimental platform was commissioned at the research institute Bijie Branch and the National Energy Large-scale Physical Energy Storage Technology (Bijie) R&D Center. All performances met or exceeded the design specifications, relying on the experimental platform. Carry out experimental research and performance testing of heat storage and heat exchange devices with power up to 10MW.

The heat storage technology can solve the problem of time and space mismatch between heat supply and demand. It is a key technology in thermal energy storage and reuse systems such as solar thermal power generation, industrial high temperature waste heat waste heat reuse, and the National Development and Reform Commission and the Energy Bureau. The importance of heat storage technology is clearly stated in the “13th Five-Year Plan” (2016-2020) and the “Energy Technology Revolution Innovation Action Plan (2016-2030)”. The high-temperature heat storage experimental platform is an important means of experiment and testing for large-scale high-temperature heat storage technology, and is of great significance for the development and application of large-scale heat storage technology. Relying on the National Energy Large-scale Physical Energy Storage Technology R&D Center Project, the Institute designed and constructed a 10MW high-temperature thermal storage experimental platform.

The high temperature thermal storage experimental platform mainly includes four components: the measurement and control system, the cold and heat source output system, the cold and heat source storage system, and the test device to be tested. The heat transfer oil such as biphenyl-diphenyl ether or silicone oil can be used as the medium to realize the temperature range. Covering normal temperature ~ 400 ° C, test power and test capacity up to 10MW and 10MWh respectively. Based on the experimental platform, it can carry out experimental research and performance testing under different temperatures, pressures and flow rates for high-temperature heat storage devices and systems, and break through the key technologies in large-scale high-temperature heat storage devices and systems. At the same time, it can be advanced to 10MW. Compressed air energy storage systems, solar thermal utilization, industrial waste heat utilization, etc. provide key experimental platform support.
