独立式海上风电制氢工艺设计

Process Design of Independent Offshore Wind Power Hydrogen Production

[目的]文章旨在为充分利用深远海优质的风资源,解决海上风电的弃风问题以及对未来新能源船舶提供一种可能的海上氢气燃料供给方式。[方法]论述了一种依托于独立式海上平台的海上风电耦合海水制氢技术的工艺流程,主要对关键设备——质子交换膜电解水制氢系统、氢气压缩机、氢气储罐及部分辅助设备的工艺设计问题进行阐述,简略说明了制氢平台的控制方案,并且对其经济性进行了初步分析。[结果]从工艺设计的角度对海上风电制氢平台上的设计仅在较为前期的阶段,关键设备的供应链市场处于发展初级时期且大部分供应商未进军海工市场,表明现今海上浮式制氢的工程设计到工程化还不成熟且可再生能源制氢经济性较差。[结论]目前,海上风电还无法做到平价上网,海洋风电耦合氢能应用还需要一个长期过程,进行工程试验是大规模工程化的前提。

[Introduction]The research aims to make full use of the high quality wind resources in the deep sea, solve the problem of wind abandonment of offshore wind power, and provide a possible offshore hydrogen fuel supply for future new energy ships. [Method]The process flow of offshore wind power coupled seawater hydrogen production technology relying on an independent offshore platform was discussed. The key equipment proton exchange membrane water electrolysis hydrogen production system, hydrogen compressor,hydrogen storage tank and some auxiliary equipment process design problems were described, with a brief description of the control scheme of hydrogen production platform, and a preliminary analysis of its economy. [Result]From the angle of process design, the design of offshore wind hydrogen production platform just in a relatively early stage. The supply chain of key equipment is in the initial development period and most of the suppliers did not enter the marine market, suggesting that current process from engineering design to the engineering of offshore floating hydrogen production is not yet mature and the economic benefit of hydrogen production from renewable energy is low. [Conclusion]At the moment, offshore wind power cannot be connected to the grid at a reasonable price, and the application of coupled hydrogen energy of offshore wind power still has a long way to go. Engineering tests are the prerequisite for large-scale engineering.
