At 03:50 on September 23, Jianshe energy storage liquid air energy Storage Project the expansion power generation system is connected to the grid for the first time and has achieved one-time success, which indicates that the core power generation cycle of the project has passed the verification smoothly. So far, the project has completed the monomer debugging of compressor, cold storage packed bed, heat exchanger, expansion generator, system auxiliary engine and the preliminary debugging of sub-cycle of gasification power generation and cold storage.

Liquid air energy storage project is the first batch of "open the list and hang handsome" project of Hebei Science and Technology Department in 2023. Liquid air energy storage technology, as the cooperation technology of Hebei Construction Investment Group and Shijiazhuang Tiedao University, the smooth implementation of the project will strongly boost the low-carbon transformation of energy structure and the construction of a new power system in Hebei province.

The successful grid-connected power generation of the expansion power generation system marks the phased victory of the whole system liquid air energy storage project, which lays a solid foundation for the next joint adjustment of the whole system energy storage and release energy.
