面向新能源规模化消纳的绿氢化工技术研究现状与关键支撑技术展望

Research Status of Green Hydrogen-based Chemical Engineering Technology and Prospect of Key Supporting Technologies for Large-scale Utilization of New Energies

可再生能源电解水制取“绿氢”并进一步合成氨、醇等化工产品,是促进新能源消纳,实现电力、化工行业深度脱碳的重要技术方向。绿氢化工技术涉及电力、化工等多学科深度交叉,但当前绿氢相关研究综述以制氢技术自身为主,尚缺乏绿氢规模化利用、绿氢与下游化工产业耦合接入电力系统等方面的梳理。为填补上述空缺,支撑绿氢化工技术发展,推动可再生能源消纳及绿氢规模化利用,首先概述绿氢化工系统各工段原理及技术特性;然后分别从绿氢化工系统自身及接入电力系统的视角梳理研究现状,分析现有研究不足;最后,展望支撑绿氢化工发展的制氢系统规模化设计与灵活调控、柔性化工合成仿真模拟、面向电力平衡调控的多工段协调控制技术,提出接入电力系统及运行的支撑系统开发需求。

Producing ammonia,methanol,and other chemical products from“green hydrogen”,essentially from renewable energy-based water electrolysis,is regarded as a key technological route toward the admittance of new energy and the decarbonization of the electrical power and chemical industry.Green hydrogen-based chemical engineering(GHCE)technology involves a deep cross between multiple disciplines.Current review papers on green hydrogen mainly focus on hydrogen production;therefore,a review on the utilization of green hydrogen coupled with the downstream chemical industry is still in need.To fill this gap,this paper first summarizes the main technical characteristics of the components in the GHCE system.Then the research status of the GHCE technology is summarized from two aspects,i.e.,the GHCE system and power system integration.Shortcomings of the current researches are analyzed.Finally,research directions are prospected,including design and flexible regulation of large-scale hydrogen production,flexibility modeling of the chemical synthesis process,and analysis and control of the GHCE system to participate in power system balancing.Requirements on key supporting systems are proposed.
