The article "Offshore green hydrogen production from wind energy: Critical review and perspective" by Shanmugam Ramakrishnan et al. discusses the potential of offshore wind energy to produce green hydrogen through electrolysis of seawater. The authors highlight the advantages of using offshore locations, which can achieve higher capacity factors (60-70%) compared to onshore sites, making them more economically viable for hydrogen production. The review covers the challenges and opportunities in offshore hydrogen production, including site selection, electrolyzer design, and the use of seawater without deionization. It compares the efficiency, cost, and lifetime of electrolysis systems operating with direct seawater feed and deionized water feed. The article also explores the impact of various factors such as pH, ion species, and microorganisms on the performance of seawater electrolyzers. Additionally, it discusses the development of electrocatalysts and membranes to improve the efficiency and stability of the process. The review concludes by emphasizing the need for further research to optimize the integration of electrolyzers with offshore wind farms and to address environmental and technical challenges.The article "Offshore green hydrogen production from wind energy: Critical review and perspective" by Shanmugam Ramakrishnan et al. discusses the potential of offshore wind energy to produce green hydrogen through electrolysis of seawater.
