Economic Analysis of Photovoltaic Hydrogen-Generation System Using Salt Cavern for Hydrogen Storage Considering Capacity Optimization
摘要
Abstract
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.关键词
