Introduction  In recent years, under the continuous promotion of carbon peaking and carbon neutrality policy, offshore wind power hydrogen production has made great progress in China as an important technology for renewable hydrogen production. The article reviews the technological routes, development status and challenges in the offshore wind power hydrogen production industry within China. Based on the analysis, it presents targeted countermeasures and recommendations, aiming to provide a foundation of insights and references for the future application and advancement of offshore wind power in the region.

  Method  Through an investigation of the research and development progress in offshore wind power hydrogen production technologies both domestically and internationally, the technological advancements and constraints were analyzed across three key dimensions: offshore wind-to-hydrogen systems, electrolytic hydrogen production technologies, and offshore hydrogen storage and transportation solutions. By evaluating the current overall development status of the industry, the current development advantages and constraints of the industry were analyzed from the aspects such as policy frameworks, market structures, and technological pathways.

  Result  The analysis highlights the existing strengths and development constraints of the industry. Notably, the industry demonstrates a diversified development trajectory, positively influencing the renewable hydrogen sector and promoting continuous advancements in electrolyzer capacity. Nonetheless, several critical challenges persist, including the absence of breakthroughs in core technologies, dependence on imported key components, elevated life cycle costs, and gaps in regulatory and policy support. These factors collectively represent significant barriers to the sustained growth and advancement of the offshore wind-powered hydrogen production industry.

  Conclusion  It is concluded that in the process of actively developing the offshore wind power hydrogen industry, the hidden bottleneck constraints should be guarded against, from the perspective of policy standards, industrial layout, core technology, etc., China should scientifically design and reasonably layout, to promote the development of the combination of offshore wind power and hydrogen industry, and to help achieve the carbon peaking and carbon neutrality goals.
