液氢储运技术及标准化

Technology and standardization of liquid hydrogen storage and transportation

液氢作为一种高效的储氢方式,其应用前景十分广阔,但储运技术相对落后、储运环节标准化的缺失限制了液氢产业的快速发展。本文介绍了液氢特性及发展现状,对液氢存储容器类型和运输方式进行对比分析,调研了液氢国内外相关标准现状,并讨论了液氢产业发展对标准体系的迫切需求,阐述了液氢储运技术的难点和未来发展方向,并对液氢储运标准体系的建立进行展望。分析表明,减少液氢储罐的蒸发率、有效降低储运设备成本将是液氢储运技术未来重要的发展方向,液氢储运技术的发展需要建立健全的标准体系,液化天然气相关标准体系对液氢储运标准化具有重要的参考意义。

As an efficient hydrogen storage method,liquid hydrogen will be widely used in the future,while relatively backward of the storage and transportation technology and the lack of related standards restrict the rapid development of the liquid hydrogen industry.This paper introduced the characteristics and development status of liquid hydrogen,compared different liquid hydrogen storage containers and transportation methods,investigated the current status of international and domestic standards of liquid hydrogen,discussed the urgent need for the establishment of liquid hydrogen standard system,analyzed the difficulties and future development of liquid hydrogen storage and transportation technology,and looked forward to the standard system of liquid hydrogen storage and transportation technology.The analysis showed that,for the storage and transportation technology of liquid hydrogen,reducing the evaporation rate of storage tanks and the cost of equipment would be an important development trend.Furthermore,a sound standard system was imperative for the development of liquid hydrogen storage and transportation technology.The LNG standard system had important reference significance for the standardization of liquid hydrogen storage and transportation.
