A team of Chinese researchers has made a breakthrough in improving the storage efficiency of renewable energy. The technological achievement was made at the world’s largest advanced compressed air energy storage (CAES) system, located in Hebei province.
The 100-megawatt facility achieved a record in efficiency during a recent test run, and will be put into commercial operation by the end of this year, according to an announcement on Tuesday on the website of the Institute of Engineering Thermophysics (IET), Chinese Academy of Sciences.
