钢铁行业的氢冶金是未来氢能规模化应用的主要场景之一，炼铁炉利用氢气作为还原剂，替代传统的碳基还原过程，从而减少温室气体排放。在氢冶金过程中，建立高效可靠的氢储运产业链是成败的关键。简述了氢冶金背景和国内外氢气储存领域的研究进展和应用现状，对各种储存技术进行了简明分析。结合氢冶金工厂的特点，提出“气固相分离式固态氢储运技术”的方案，理论上可实现经济、安全、长距离、面向工业应用的大规模氢储运。未来可通过工程化手段实现大宗含氢物料的制备和存储运输，并与冶金或化工工厂的原料工艺流程实现有效衔接，对上游合金资源产业和可再生能源制氢产业也有重要推动作用。

Hydrogen metallurgy in the steel industry will be the main scenario for large-scale hydrogen application in the future. Blast furnaces can use hydrogen as a reducing agent to replace the traditional carbon-based reduction process, thereby reducing greenhouse gas emissions. In the process of hydrogen metallurgy, establishment of an efficient and reliable hydrogen storage industry chain is the key to success. A brief review on hydrogen metallurgy and worldwide development of hydrogen storage and transportation tech especially via solid-metal hydride is given in this paper. Combined with the demand on hydrogen storage and transportation for hydrogen metallurgy, a scheme for massive H2 usage in iron&steel plant via conceptional "gas-solid-gas phases" separate charge&discharge system by solid-metal hydride is proposed to reach a theoretically economic, safe, longdistance and scale-up industrial application. In the future, production and storage&transportation for massive H2-contained solid material for raw-material handling process in iron&steel or chemical plants will be realized by attainable engineering, which will propel revolutionary change in the upstream alloy industry and green H2-via-renewable industry.
