Design Specification for Hydrogen-Ammonia Coupled Offshore Wind Power Abandonment Utilization System with Pd Catalysts
Year: 2025
Type: article
Abstract: As China's offshore wind power develops into deep and distant sea and large scale, the problems of power abandonment, consumption and energy storage are highlighted, and the traditional grid-connected mode causes energy waste. This work is based on palladium (Pd) catalyst hydrogen-ammonia coupling system, through the "on-site hydrogen synthesis ammonia", to realize the conversion of abandoned power and green hydrogen storage and transportation, to develop a new path of new energy utilization. The system integrates PEM water electrolysis to produce hydrogen and Pd catalyzed nitrogen reduction to synthesize ammonia, breaking through the traditional bottleneck. Adopting Pd/graphene composite electrode, the electrolysis efficiency reaches 75% (15% improvement), and the Pd catalyst activates nitrogen at low potential and suppresses hydrogen precipitation. The "electricity-hydrogen-ammonia" triple-supply converts hydrogen into liquid ammonia (containing 17.6 wt% hydrogen), with storage and transportation costs of only 1/15 of hydrogen. 2.4×10⁸ kWh of abandoned electricity is handled annually by an offshore wind farm in Jiangsu, resulting in a significant reduction in emissions. The modular design is adapted to the offshore platform, and combined with intelligent scheduling to realize more than 90% of abandoned power consumption.
