Abstract: Global offshore wind faces rising threats from frequent extreme typhoons and prolonged low-wind spells that erode power-system resilience. To counter these challenges, we present an offshore wind–hydrogen hybrid that integrates alkaline water electrolysers and proton exchange membrane electrolysers, hydrogen tanks, and fuel cells, and we develop a mixed-integer linear programming life-cycle-cost model driven by hourly wind data for a continuous typhoon to calm extreme scenarios. Compared with the traditional scenario of an alkaline water electrolyser plus battery, the proposed hybrid electrolyser plus hydrogen storage cuts the extreme-weather loss-of-load probability from 40.4% to 17.5% (a reduction of 60%), halves the annual expected energy not served to 943 MWh, reduces the levelized cost of hydrogen by 22% from 4.64$ to 3.59$/kg, adds 27 million dollars in life-cycle revenue, and shortens the payback by 3.6 years, delivering an economical, resilient, and readily replicable hydrogen solution for high-penetration offshore wind grids under extreme weather. These findings underscore the potential of the system to improve both economic profitability and risk resistance, offering a promising solution for enhancing the resilience and economic performance of offshore wind–hydrogen systems.
