Compressed/liquid air energy storage is a novel energy storage technology which can utilize intermittent renewable energy or nightly off-peak electric power. By this technology, electric power can be stored in the form of compressed/liquid air and the compressed/liquid air will be released to drive turbo-generator set for generation when needed.

Collaborated with the Institute of Physics and Chemistry(CAS),TsinghuaUniversityand the State Grid, we have designed the first demonstration project of 500 kw advanced adiabatic compressed air energy storage. It realized the integrated design and stable operation of air storage, energy release, heat storage and synchronization. Our novel multistage coaxial turboexpander features the advantages of high expansion ratio, high adiabatic efficiency, high speed, high compactness, simple structure and easy maintenance.

Energy storage power: 0~10000 kW

Generation time: 0~10 h

Utilization of electrical energy: synchronization or self use
