摘　　要：针对我国绿氢碳足迹量化缺乏统一核算方法的问题,对比分析了国内外绿氢碳足迹核算标准,建立了一种涵盖绿电生产与输出、电解水制氢、氢气储存、氢气运输等全生命周期的碳足迹量化模型,并进行了实际案例的碳足迹核算。研究结果表明,风电电解水制氢较光伏电解水制氢具有更低的碳排放量,同时提出了提高电解槽能效,优化储氢和运氢过程、加大对新型电解技术的研发力度等建议。In response to the lack of a unified accounting method for quantifying the carbon footprint of green hydrogen in China,this paper compares and analyzes the domestic and international standards for accounting the carbon footprint of green hydrogen.A carbon footprint quantification model covering the full life cycle,including green power production and output,electrolytic water hydrogen production,hydrogen storage,and hydrogen transportation,is established,and carbon footprint accounting is carried out on actual cases.The research results show that hydrogen production through electrolysis of water using wind power has a lower carbon emission than that of using photovoltaic power.Suggestions are also put forward,such as improving the energy efficiency of electrolyzers,optimizing the hydrogen storage and transportation processes,and increasing research and development efforts on new electrolysis technologies.
