Technoeconomic Assessment of Integrated Wind‐Powered Electrolysis Systems With Compressed Hydrogen Storage for Grid Balancing and Transportation Fuel Applications

Wind power’s intermittent nature presents challenges for grid integration, while hydrogen production via electrolysis offers potential solutions for both energy storage and clean transportation fuel. This study conducted a comprehensive technoeconomic assessment of integrated wind‐powered electrolysis systems with compressed hydrogen storage to determine optimal configurations and economic viability. Five system configurations were modeled, combining direct wind‐to‐electrolysis coupling and grid‐connected operation with varying storage capacities. Technical performance was simulated using actual wind data from three geographic locations, while economic analysis employed discounted cash flow methodology, examining multiple revenue streams. Direct‐coupled systems achieved 62.4% average efficiency from wind to hydrogen, while grid‐connected systems reached 68.7%. The hybrid configuration demonstrated superior economic performance, achieving levelized hydrogen costs as low as $3.39/kg in favorable locations. Grid balancing services reduced production costs by 13.8% for hybrid systems. Carbon abatement costs ranged from $46.3 to 142.7/ton CO 2 eq without incentives, decreasing to $5.8–58.2/ton with enhanced policy support. The results indicate that wind‐powered electrolysis systems can achieve economic viability in specific markets when implementing revenue stacking strategies. Geographic location significantly impacts performance, with the wind capacity factor being more influential than peak wind speeds. Policy incentives remain critical for near‐term deployment, though projected cost reductions suggest competitive hydrogen production without subsidies is achievable by 2030.
