As a front-end equipment for hydrogen energy application, hydrogen refueling piles are an important guarantee for hydrogen energy application, and key equipment is in the stage of domestic substitution. With the increase in the number of hydrogen vehicles, the construction of hydrogen refueling stations also needs to be accelerated to ensure reliable hydrogen supply for vehicles. Among them, compressors are the core equipment of hydrogen refueling stations, with high technical barriers for compressors. Overseas compressor manufacturers occupy a dominant position in domestic hydrogen refueling stations; Promote the domestic substitution of key equipment for hydrogen refueling stations, and ensure the independent and controllable industrial chain.
