制氢加氢“子母站”建设规划浅析

通过简要介绍制氢加氢合建站规划设计的现实意义和国内外加氢站发展现状，提出制氢加氢“子母站”的概念。本文简要介绍了制氢加氢“子母站”的建设模式，即制氢加氢“子母站”采取分布式供氢模式，“母站”制氢加氢集成为一体，“子站”作为纯加氢站，“母站”与“子站”之间采用长管拖车运输，“母站”为制氢加氢一体站，“母站”总装置内的供氢单元主要考虑采用天然气制氢、甲醇制氢和电解水制氢3种模式。简要分析了天然气制氢、甲醇制氢、电解水制氢技术的优缺点，并从氢气的生产成本、氢气的储运成本、制氢加氢“子母站”中制氢站的建设成本、运营成本等几方面进行了较为详细的成本分析。通过供氢模式的特点和成本分析，提出以水电解制氢、甲醇制氢、天然气制氢装置作为氢源的制氢加氢“子母站”为适宜我国能源结构的新型氢能利用模式。

A brief analysis on"distributed-centralized hydrogen producing and filling station"planning

It proposes an idea of “distributed-centralized hydrogen producing and filling station”, by briefly introducing and reviewing the practical significance of the planning and design of the integrated hydrogen production and filling stations and the development status of hydrogenation stations. The module of “distributed-centralized hydrogen producing and filling station” is a kind of distributed hydrogen supply module: “centralized station” integrates hydrogen producing and filling; while “distributed station” is only related to hydrogen filling and the hydrogen is from “centralized station” by trailer. On-site hydrogen producing is hydrogen source for “centralized station”, including SMR, methanol reforming and electrolysis. It briefly compares the pros and cons of the said three hydrogen producing technologies. It analyzes the costs of these technologies in detail, including hydrogen producing cost, hydrogen storage and logistic cost, station CAPEX and OPEX. According to the characteristics and cost analysis of the hydrogen supply mode, the “distributed-centralized hydrogen producing and filling station” supported by SMR, methanol reforming and/or electrolysis would be fit to China energy structure and the new hydrogen energy utilization mode.
