摘　　要：为解决目前氢能不易储运的问题,提出了一种基于绿氢和生物质富氧燃烧技术的零碳甲醇合成系统。该系统利用光伏和风电等绿色电力,通过碱性电解槽技术制取氢气,再利用生物质富氧燃烧电厂产生的富含二氧化碳的尾气与氢气合成甲醇,实现了整个系统碳的近零排放,并对该系统进行了能量分析和经济性分析。结果表明:零碳甲醇合成系统的系统综合能量效率为47.3%;当电价为0.2元/(kW·h)时,该系统的动态回收周期为4.24a,净现值为9685.39万元。In order to solve the problem of difficult storage and transportation of hydrogen energy,a zero carbon methanol synthesis system based on green hydrogen and biomass oxygen enriched combustion tech-nology was proposed.The system used green power such as photovoltaic and wind power to produce hy-drogen through alkaline electrolytic cell technology,and then used the tail gas rich in carbon dioxide pro-duced by biomass oxygen enriched combustion power plant to synthesize methanol with hydrogen,realizing nearly zero carbon emission of the whole system.On this basis,the energy analysis and economic analysis of the proposed system were carried out.Results show that the comprehensive energy efficiency of zero carbon methanol synthesis system is 47.3%;When the electricity price is 0.2￥/(kW·h),the dynamic recovery period of the system is 4.24years,and the net present value is 96.8539million yuan.
