Introduction  In order to promote the achievement of "carbon peak and neutrality" goals in China, deeply promote the revolution of production and consumption, and build a clean, low-carbon, safe and efficient energy system, the development of hydrogen energy industry is of great significance. Accelerating the development of hydrogen refueling stations is the key to realizing the whole chain of hydrogen energy, and is an important guarantee to realize the healthy and rapid development of hydrogen energy industry. Due to the large scale of hydrogen energy consumption of petrochemical and chemical enterprises and the rapid development of hydrogen fuel cell vehicles and other vehicles in the Yangtze River Delta, promoting the development of hydrogen refueling stations and network construction is the top priority for the promotion of hydrogen energy.

  Method  The current situation of the approval process and policy environment of hydrogen refueling station construction in the Yangtze River Delta was analyzed through literature research method, case study method, survey research method and economical measurement, and the obstacles that restrict the development of hydrogen refueling station construction in the Yangtze River Delta were identified.

  Result  The lack of legal support for the energy attributes of hydrogen, the lack of guidance for construction standards, and the inadequate multi-sectoral collaboration mechanism have restricted the construction of hydrogen refueling stations and hindered the development of the hydrogen energy industry.

  Conclusion  It is suggested to improve the laws and regulations related to hydrogen energy, clarify the boundary conditions between "hazardous chemical" and "energy" of hydrogen energy, improve the construction standards and approval process of hydrogen refueling stations, focus on the core technology, increase financial subsidies, accelerate the promotion of fuel cell vehicles, and promote the development of hydrogen energy industry.
