大型液氢储罐内罐材料研究与应用进展

RESEARCH AND APPLICATION PROGRESS OF INNER TANK MATERIALS FOR LARGE LIQUID HYDROGEN STORAGE TANKS

国外液氢应用技术起步较早,液氢储罐的设计制造能力已达到最大3800 m^(3)储罐应用案例,相关技术主要由美、日、俄等国所掌握;中国液氢应用技术起步较晚,液氢储罐设计制造能力上限为300 m^(3)储罐,与国际先进水平相比还有较大差距。由于液氢储罐内罐材料的设计、制造属于其最关键核心技术之一,因此,该文综述了液氢储罐内罐材料的研究进展及发展现状,并对生产标准、中国制造能力等进行分析,对下一步液氢储罐材料的技术开发和试制提出建议。

The application technology of liquid hydrogen in foreign countries started relatively early,and the design and manufacturing capacity of liquid hydrogen storage tanks has reached the maximum 3800 m^(3) storage tank application case.The relevant technologies are mainly mastered by the United States,Japan,Russia and other countries.The application technology of liquid hydrogen in China started relatively late,and the upper limit of the design and manufacturing capacity of hydrogen storage tanks is 300 m^(3),which is still far behind the international advanced level.Since the design and manufacture of the inner tank material of liquid hydrogen storage tank is one of its most critical core technologies,this paper summarizes the research progress and development status of the inner tank material of liquid hydrogen storage tank,and conducts research on production standards and domestic manufacturing capacity,etc.Based on the analysis,the suggestions for the technical development and trial production of liquid hydrogen storage tank materials in the next step are proposed.
