摘　　要：液氢能量密度高,作为氢的储运形式在远距离运输上具有成本优势。在减碳政策引导下,全球范围内液氢市场将进一步扩大,但氢液化装置能耗过高制约了液氢市场的发展。本文聚焦于国内外氢液化装置产业化现状,调研了国内外液氢产能和氢液化装置供应商;回顾了国际上两个典型氢液化装置的建设情况、流程特点和关键性能指标;梳理了近几年文献公开的氢液化流程的预冷方式、液氢产量和能耗,并且详细介绍了日本WE-NET项目和欧洲IDEALHY项目的氢液化流程;总结了氢液化装置的技术难点和发展现状。分析表明,低能耗氢液化流程设计已相对成熟,提升核心设备的效率和可靠性、完善液化过程的动态控制策略是推动氢液化装置产业化的关键。大型氢液化装置实现规模效应、小型氢液化装置提升启停能力是两个重要的发展方向。Liquid hydrogen has high energy density,and it has cost advantage in long-distance transportation.Under the guidance of carbon reduction policies,the global liquid hydrogen market will be further expanded.However,the liquid hydrogen market is restricted by the high energy consumption of hydrogen liquefier.This study focused on the industrialization status of hydrogen liquefier.First,domestic and foreign liquid hydrogen production capacity and liquefier providers are investigated.Then,the construction status,thermodynamic process and key performance parameters of two typical hydrogen liquefiers are reviewed.Further,the pre-cooling methods,liquid hydrogen production capacity and energy consumption of hydrogen liquefaction processes published in recent years are summarized,and the hydrogen liquefaction processes of WE-NET project and IDEALHY project are introduced in detail.In addition,the technical difficulties of hydrogen liquefier are described.The analysis showes that improving the efficiency and reliability of core equipment and developing the dynamic control strategy of liquefaction process are the keys to promote the industrialization of hydrogen liquefier.Large-scale hydrogen liquefier to achieve scale effect and small-scale hydrogen liquefier to improve the start-stop speed are two important development directions.
