In recent days, the institute of engineering thermal physics of the chinese academy of sciences has made a breakthrough in the development of compressed air storage technologies. The first and most single-powered international compressed air storage compressors developed by the institute's joint reserve state energy (beijing) limited were tested through third parties. The test showed that the compressor had a maximum exhaust pressure of 10. 1 mpa and a maximum power of 101 mw, with a variation range of 38. 7 to 118. 4 per cent, and an efficiency of 88. 1 per cent under the maximum exhaust pressure. Compressors are one of the most important core components of compressed air storage systems, whose role is mainly to compress air pressure to high pressure during storage, and to store it in gas storage units to achieve the process of converting electrical energy into air pressure and thermal energy. Through its autonomous innovations, the engineering thermal institute has broken through key technical challenges such as overall design and optimization, full-dimensional mobility optimization, long rotor complex axis structure design, high-efficiency change job situation control, and has successfully developed an international first set of mono-powers exceeding 100 mw compressed air storage compressors with full intellectual property rights. The single power of compressed air storage compressors has increased by more than 100 per cent and the unit cost has been significantly reduced, with the advantages of efficiency, stress and wide range. The engineering thermal institute has been conducting the first studies of compressed air storage technologies in the country since 2005. After more than 20 years of effort, the original project introduced new advanced compressed air storage principles, which breakthroughd key technologies such as the full system design, wide load compressor, high-efficiency compact heat exchanger, high-load inflator; completed a complete compressed air storage design system covering “system design - key components - integrated control”; and pioneered the 1. 5 mw-10mw-100mw-300mw advanced compressed air energy national demonstration project. The work is supported by the strategic science and technology initiative of the chinese academy of sciences (category a), the national priority research and development programme project and the youth science fund project of the national natural science fund (category a).
