The objectives of this paper are to perform comprehensive evaluation of design, cost analysis, and risk assessment of a modular scale green hydrogen production system powered by offshore wind energy. In this paper, an offshore bridge-linked hydrogen hub has been considered with a fixed offshore substation supplying electrical power where renewable hydrogen is generated through water electrolysis. In this approach, a bridge-linked platform is assumed to connect an offshore substation and an offshore hydrogen hub. The offshore substation directly supplies the renewable excess power to the hydrogen hub for producing green hydrogen. A Proton Exchange Membrane (PEM) electrolyzer system is used for splitting the water into hydrogen and oxygen, producing the hydrogen gas. An economic analysis of the green hydrogen production is performed for various scenarios based on the recent and forecasted costs of offshore wind power and PEM electrolyzer. The risks arising due to hydrogen production and storage are also discussed. By bridging the offshore wind substation and offshore hydrogen hub platforms, the capital expenditure (CAPEX) of the design could be reduced significantly such as less export cable requirement and direct supply of power to the hydrogen hub, along with the reduction in the cost of operation and maintenance (O&M). Considering the recent forecasted costs of PEM electrolyzer and its lifetime, and those of offshore wind power, the production cost of green hydrogen could be reduced significantly soon. This study suggests that a detailed understanding of risk management is needed for hydrogen production and storage at the hydrogen hub and transport hydrogen to onshore for various applications. The integration of the offshore wind energy substation and the offshore hydrogen hub could help green hydrogen cost to be reduced significantly and better advance further energy sustainability. Also, the study can help manage the risks of green hydrogen production by reducing the carbon footprint for practical applications.
