Abstract: Abstract：[Introduction] In order to solve the problems of high investment in electrolytic water hydrogen production project, prominent contradiction between the realization of hydrogen production function and the project yield, and quickly promote the market-oriented application of hydrogen production equipment, it is necessary to carry out the economic research on the configuration optimization of electrolytic water hydrogen production system. [Method] In this paper, the two system configuration modes of a type of 1000m hydrogen production system are analyzed according to three different hydrogen production modes. The hydrogen cost and profitability data before and after the optimization of hydrogen production system configuration are compared, and the hydrogen produc-tion system configuration scheme that meets the project investment conditions is studied. [result] the economic effect of configuration optimization of electrolytic water hydrogen production system was summarized, which has reference significance for the application of the same scale of electrolytic water hydrogen production system in hydrogen production projects in the future. [Conclusion] Through the analysis of five hydrogen production models in this paper, it can be seen that the income of hydrogen production project is affected by the hydrogen power supply mode. Through the optimization of hydrogen production power supply mode in the design scheme, the cost of levelized hydrogen can be reduced by 8.00 yuan/kg, and the financial internal rate of return of capital can be increased by about 8%, which largely solves the problem of low profitability of hydrogen production project.
