Economic Analysis of Photovoltaic Hydrogen-Generation System Using Salt Cavern for Hydrogen Storage Considering Capacity Optimization
文章对采用盐穴储氢的光伏制氢模型进行构建并研究其经济性.首先,对盐穴进行物理建模计算其储氢能力,并构建光伏制氢系统,针对压力容器储氢方案与盐穴储氢方案进行对照分析.然后,以成本最小化为目标,利用混合整数规划模型优化各方案容量,并对优化结果进行技术经济性分析.最后,选取4种因素对采用盐穴储氢方案进行敏感性分析.结果表明,采用盐穴储氢的光伏制氢系统的氢气平准化成本为32.18元/kg,相较于压力容器储氢方案成本减少8.73％,盐穴方案的最终净现值高于压力容器方案20.65％,投资回收期缩短10.14％,内部收益率更高.对光伏制氢盐穴储氢方案经济性的影响由大到小依次为太阳辐照量、光伏与电解槽资本成本和盐穴埋深,因此,在未来光伏与电解槽成本下降趋势下,在西部辐照量资源丰富的区域进行光伏制氢盐穴储氢将更具经济可行性.
In this study,a photovoltaic(PV)hydrogen-production model using salt caverns for hydrogen storage is constructed and its economy is analyzed.First,salt caverns are physically modeled to calculate the hydrogen-storage capacity.Subsequently,a PV hydrogen-production system is constructed,pressure-vessel and salt-cavern hydrogen-storage schemes are set to be analyzed against each other,and the capacity of each scheme is optimized using a mixed-integer planning model for cost minimization.Next,the results of the optimization are analyzed via techno-economics analysis.Finally,a sensitivity analysis is performed for the salt-cavern storage scheme based on four factors.The results show that the levelized cost of hydrogen in the PV hydrogen system using salt-cavern storage is $ 32.18/kg-H2,which is 8.73％ lower than the cost incurred by the pressure-vessel hydrogen-storage scheme.Additionally,the final net present value of the salt-cavern scheme is 20.65％higher than that of the pressure-vessel scheme,with a shorter payback period of 10.14％and a higher internal rate of return.The factors influencing the economy of the salt-cavern hydrogen-storage scheme for PV hydrogen production are,in the descending order,solar irradiation,capital cost of PV and electrolyzer,and salt-cavern burial depth.Therefore,establishing PV-to-hydrogen salt-cavern hydrogen storage in western irradiation-rich areas is more economically feasible in the future when the costs of PV and electrolyzers are lower.
