Liquid air energy storage technology is a new type of large-scale energy storage technology, its main feature is the traditional compressed air energy storage technology based on the introduction of low-temperature process, the high-pressure air liquefied atmospheric or low pressure storage, with high energy density, Relatively low cost, small dependence on geographical conditions and other advantages, suitable for large-scale popularization and application, can largely solve the intermittent and volatile renewable energy power generation issues and enhance grid stability.The development of this technology for the current Restricting China's renewable energy abandoned wind power rationing and other challenges of great significance.
A research team led by Wang Junjie, a researcher at the Institute of Physics and Chemistry, Chinese Academy of Sciences, conducted a detailed and in-depth study on the basic theory and simulation of cryogenic liquid air energy storage technology. Innovatively proposed efficient use of cascade thermostat, small temperature difference heat transfer Cold storage process, an international first set of liquid air energy storage experimental platform based on two-stage liquid-phase refrigerant storage was built in the Langfang Campus of the Physical and Chemical Institute. The cooling storage efficiency test results reached 90%, which is at the leading level in the world.
The work was supported by the key project of Beijing Natural Science Foundation "Basic research on new efficient and low temperature liquid air energy storage", and the project cooperation units Tsinghua University and Beijing University of Aeronautics and Astronautics played a good supporting role. Published 13 papers, many papers published in Energy Conversion & Management, Energy and other journals, the core technology to apply for 12 national invention patents, authorization 2.
The construction of the liquid air energy storage platform of this project has been supported by the 'Research on Platform of Cryogenic Liquid Air Storage System' funded by the Director of the Physical and Chemical Institute and the related industrialization promotion has started.
