Kehua's Milestone: China's First 100MW Liquid Cooling Energy Storage Power Station in Lingwu. Explore the advanced integrated liquid cooling ESS powering up the Gobi, enhancing grid flexibility, and providing peak-regulation capacity equivalent to 100,000 households' annual consumption.
4.1. Standalone liquid air energy storage In the standalone LAES system, the input is only the excess electricity, whereas the output can be the supplied electricity along with the heating or cooling output.
Concluding remarks Liquid air energy storage (LAES) is becoming an attractive thermo-mechanical storage solution for decarbonization, with the advantages of no geological constraints, long lifetime (30–40 years), high energy density (120–200 kWh/m 3), environment-friendly and flexible layout.
The heat from solar energy can be stored by sensible energy storage materials (i.e., thermal oil) and thermochemical energy storage materials (i.e., CO 3 O 4 /CoO) for heating the inlet air of turbines during the discharging cycle of LAES, while the heat from solar energy was directly utilized for heating air in the work of .
2.1. History 2.1.1. History of liquid air energy storage plant The use of liquid air or nitrogen as an energy storage medium can be dated back to the nineteen century, but the use of such storage method for peak-shaving of power grid was first proposed by University of Newcastle upon Tyne in 1977 .
The power station is equipped with 63 sets of liquid cooling battery containers (capacity: 3.44MWh/set), 31 sets of energy storage converters (capacity: 3.2MW/set), an energy storage converter (capacity: 1.6MW), a control cubicle system and an energy management system (EMS).
