On April 20th, CGDG signed an investment agreement with the Technical Institute of Physics and Chemistry of the Chinese Academy of Sciences, to establish a company and build a world-class liquid air energy storage (LAES) technology platform. Shortly, the two companies will start the construction of the first 50MW/600MWh LAES demonstration project. Based on novel technologies, LAES is a new approach to accommodate more renewable energy such as wind and solar, intake the redundant electricity in low demand periods and different forms of waste thermal resources, and stably output many forms of energy like cold, heat, electricity and gas, etc.
