Abstract

Research on fuel cell hydrogen refueling stations is mostly concentrated on newly-built stations, and there are few studies on the combined hydrogen and CNG refueling stations. The construction plan of combined hydrogen and CNG refueling stations is conducive to planning and layout, solving the difficulties in land use of hydrogen refueling stations, and reducing construction investment and operating costs. This paper analyzes the feasibility of the combined station construction, studies the construction plan and scale of the combined station, and proposes its general layout plan.

Highlights

  • The grading of the combined hydrogen and CNG refueling station construction shall comply with the relevant regulations [4], specific data refer to Table 1

  • According to the above method, the general layout of the combined station is carried out, the results are shown in Figure 1 and Figure 2

  • Adding hydrogen refueling facilities to the gas refueling station is an important way to accelerate the construction of hydrogen refueling stations

Summary

Market demand for hydrogen fuel cell vehicles

From 2016 to 2019, the sales of hydrogen fuel cell vehicles in China were 629, 1275, 1527 and 2,737 respectively. In 2020, the development of fuel cell vehicles reaches a new level. China's hydrogen fuel cell vehicles are mainly used in the field of commercial vehicles, namely passenger vehicles and freight vehicles. Passenger vehicles have fixed driving routes, and the types of vehicles in the passenger market mainly depend on the planning of the local government. They are highly driven by the government and are conducive to the development of hydrogen fuel cell vehicles. CNG vehicles have been well promoted and applied in various provinces and cities in China, especially in the field of commercial vehicles such as buses. Because the refueling location is relatively fixed, the combined construction of hydrogen and CNG refueling stations is suitable
