Study and Analysis of Investment and Operation Cost of Dynamic Coupling Technology for Key Equipment in Green Hydrogen Production

The paper focuses on the development model of green hydrogen production through the coupling of new energy and hydrogen, particularly in the “Wuchangshi” region of Xinjiang. It analyzes the technical characteristics of two mainstream water electrolysis hydrogen production technologies: alkaline water electrolysis (AWE) and proton exchange membrane electrolysis (PEM). Using a learning curve model, it predicts the dynamic parameters of key equipment for both technology routes. Additionally, it plans a hydrogen production rate of 20,000 Nm<sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sup>/h, selects the predicted parameters for key equipment in 2025, and estimates the costs of hydrogen production for both alkaline water electrolysis and proton exchange membrane electrolysis routes. The paper also analyzes and compares the costs of hydrogen production. Research findings indicate that in the “Wuchangshi” region of Xinjiang, where a hydrogen power plant is planned for 2025, the cost of hydrogen production using alkaline water electrolysis technology remains more advantageous. Compared with other literature on hydrogen production costs, both technical routes have significant economic advantages. With future technological advancements, reduced equipment costs, and adjustments in electricity prices, the normalized production costs of PEM and AWE technologies are expected to further decrease, enhancing the competitiveness of green hydrogen production and demonstrating substantial economic potential and market prospects in the integrated hydrogen production sector combining wind and solar power generation.
