制氢技术进展及经济性分析

The Progress and Economic Analysis of Hydrogen Production Technology

氢不仅能满足全球日益增长的能源需求,还能降低CO_(2)排放,是未来新能源系统的重要组成部分。化石燃料生产的蓝氢可以用于从灰氢到绿氢的过渡期,减少当前制氢过程中的碳排放,但目前无法满足行业对脱碳的需求。中短期内,蓝氢将占据氢市场的主导地位。可再生能源制绿氢技术符合未来净零碳排放的目标,其中碱性和质子交换膜电解槽技术发展相对较为成熟,离子交换膜和固体氧化物电解槽尚处于研发阶段。长期内,随着电解槽技术发展及可再生能源成本下降,绿氢将占据主要市场。

Hydrogen can not only meet the world’s growing energy demand,but also reduce carbon dioxide emissions,which is very important for the future energy industry.The blue hydrogen produced by fossil fuel can be used in the transition period from grey to green hydrogen to help reduce carbon emissions from current hydrogen production processes,but cannot meet the industry's need for decarbonization.In the short to medium term,blue hydrogen will dominate the hydrogen market.The green hydrogen produced by renewable energy meets the goals of future net-zero emissions.Among them,the development of alkaline and proton exchange membrane electrolyzer technology is relatively mature,and ion exchange membranes and solid oxide electrolyzer is still in the research and development stage.In the long term,green hydrogen will dominate the market as electrolyzer technology develops and the cost of renewable energy falls.
