氢气存储与加注设备技术现状及发展趋势OA

To clarify the technological development direction of hydrogen storage and refueling equipment and promote large-scale,high-quality hydrogen energy development,this study analyzes four hydrogen storage technologies:high-pressure gaseous storage,cryogenic liquid storage,solid-state material storage,and organic liquid storage.It identifies technical shortcomings in vehicle-mounted hydrogen storage systems and core equipment for hydrogen refueling stations,examines China's hydrogen refueling station industry landscape and regional clustering characteristics,and proposes development trends for refueling equipment technology.Research reveals that,current vehicle-mounted hydrogen storage primarily uses 35 MPa type Ⅲ cylinders,while type Ⅳ cylinders have not yet achieved commercial adoption.Core hydrogen refueling station equipment faces widespread technical constraints,including low storage capacity,high equipment costs,heavy reliance on imports,and susceptibility to hydrogen embrittlement.China leads the world in hydrogen refueling station scale,with modular hydrogen refueling stations being the mainstream construction approach domestically.Liquid hydrogen refueling stations,driven by high energy density,represent a future development direction but remain in the early stages.Future advancements in hydrogen storage and refueling technologies will focus on high density,efficiency,low energy consumption,enhanced safety,and intelligent integration.Accelerating the deep integration of domestic equipment manufacturing,standardization,and industrial clustering will help overcome current technological bottlenecks and industrial development constraints.
