氢能作为清洁高效可再生的能源，对能源多元化和能源安全保障方面具有重要意义，受到了全球范围的高度关注，目前存在较大技术瓶颈的主要是大规模氢能储运环节。氢能储运主要包括高压气态储氢、液氢储存、固态储氢和液体载体储氢几种方式。其中，结合当前产业和技术的整体发展水平，目前最可行的方案是利用液体载体储氢技术中的液氨储氢，其核心是低温液氨氢能储运站。本文对低温液氨氢能储运站基本流程和一些工艺设计关注点进行了分析，并对液氨储氢路线的发展提出了建议和展望。

Hydrogen energy,as a clean,efficient and renewable energy source,is of great significance for energy diversification and energy security,and has received high attention globally.Currently,the main technological bottleneck is the large-scale hydrogen energy storage and transportation process.Hydrogen energy storage and transportation mainly include high-pressure gaseous hydrogen storage,liquid hydrogen storage,solid-state hydrogen storage and liquid carrier hydrogen storage.Among them,based on the overall development level of the industry and technology,the most feasible solution at present is to use liquid ammonia-based hydrogen storage,which is a technology of hydrogen storage in liquid carriers.Its core is the cryogenic liquid ammonia-based hydrogen energy storage and transportation station.This paper analyzes the basic process flow and some key points of process design of cryogenic liquid ammonia-based hydrogen energy storage and transportation stations,and puts forward suggestions and prospects for the development of liquid ammonia-based hydrogen storage routes.
