摘　　要：本文以可再生能源SPE电解制氢工程为研究对象,绿电制氢产能选择1000 Nm^(3)/h,使用工程经济学的项目投融资分析理论,系统地研究了1000 Nm^(3)/h绿电制氢厂的总投资、总成本费用、经营成本、售氢收益等,获得了累计净现值(NPV)、内部收益率(IRR)和静态投资回收期(P_(t))等关键指标。结果表明,制氢厂总投资11176.94万元,占地面积10.47亩(1亩=666.67 m^(2)),经营成本中年电量消耗占比达86.4%,是制氢厂运营期间的最大成本。本文计算条件下,制氢厂有关财务指标为NPV=21732.1万元≥0,P_(t)=8.8年,IRR=11.63%。同时,研究还发现设备购置费、加氢站枪口价格、绿电电价和政府补贴对制氢厂的经济性非常敏感,投资者要根据地方社会条件因地制宜实施差别化决策。研究还指出,制氢厂产能达到308 Nm^(3)/h时,即生产能力利用率(EBP)为30.08%,开始达到盈亏平衡点,盈亏平衡点随着运营年份动态向上迁移,因此制氢厂要尽量满制,提高产能以获取更多经济收益。最后,研究还指出制氢厂寿期实施大修1次,投入按购置设备费20%择取,IRR为11.05%。政府补贴持续15年,IRR(寿期一次大修)为8.1%,NPV为7438.6万元。This paper takes SPE electrolytic hydrogen renewable energy project as the research object and analyzes the total investment,total cost,operating cost and profit of 1000 Nm^(3)/h plant through the engineering economics of methodology,which obtains the key financial indicators such as accumulative NPV,IRR and static investment payback period(P_(t)).The total investment of the hydrogen plant is 11.178 million yuan with the area of 10.47 mu(1 mu=666.67 m^(2)).The result shows the electricity consumption accounts for 86.4% of the operating cost,which is the largest cost during the operation.Under the calculation conditions,the relevant financial indicators of the SPE hydrogen technology plant are NPV=21.7321 million Yuan≥0.P_(t)=8.8 years and IRR=11.63%.At the same time,it is found that the economic values of SPE electrolytic hydrogen renewable energy project is very sensitive to equipment purchase cost,muzzle price of hydrogen refueling station,green electricity price and government subsidies.Investors need to fully consider the local situations to make a decision.The study also points out that when the capacity of the hydrogen plant has reached 308 Nm^(3)/h,i.e.,the production capacity utilization ratio(EBP)is 30.08%,it begins to reach the balance point.The balance point is rising with the years of operating,that means hydrogen plant should be fully operated to make more profits by maximum production with highest efficiency.Meanwhile,IRR is 11.05%based on one time overhaul and 20% of the equipment cost during the life span.If the government subsidies last for 15 years,the IRR is 8.1%(one time overhaul)and the NPV is 74.386 million.
