Core Insights - The Zhangjiakou Wind-Hydrogen Integration Source Network Load Storage Comprehensive Demonstration Project (Phase I) has initiated the EPC general contracting bidding for its hydrogen production segment, marking it as Hebei Province's first large-scale wind-hydrogen integration project [1] - The project aims to reduce green hydrogen production costs and promote the large-scale application of fuel cell vehicles through renewable energy off-grid hydrogen production [1][2] - The project leverages Zhangjiakou's abundant wind energy resources and employs a "wind-hydrogen integration" model to directly use wind power for water electrolysis, which is expected to significantly lower electricity costs in the hydrogen production process [1] Industry Developments - The cost of fuel cell systems has significantly decreased in recent years, supported by national and local policy incentives, bringing the purchase cost of fuel cell vehicles closer to market promotion thresholds [1] - However, high hydrogen supply costs, particularly for green hydrogen, remain a critical bottleneck for the large-scale development of the industry [1] - The project is expected to reduce the green electricity hydrogen production cost to below 18 yuan/kg upon reaching full production capacity, providing strong support for the large-scale promotion of fuel cell vehicles and establishing a sustainable and replicable economic development model for China's hydrogen energy industry [2]
