In this study, a conceptual design was developed for a facility for liquefied hydrogen production. As global warming has emerged as a major challenge for humanity, the energy industry is transitioning from fossil fuels to renewable energy sources. Although renewable energy is abundant and environmentally friendly, it suffers from intermittent production. To address this limitation, energy storage systems are gaining prominence, and among them, hydrogen has attracted significant attention because it can be stored in large quantities over extended periods. Hydrogen offers a high energy density per unit mass and can be used as a fuel in various industries; however, it has a low energy density per unit volume, which makes its storage and transportation difficult. To overcome these drawbacks, considerable interest has been directed toward the liquefaction of hydrogen for storage and transportation. When hydrogen is produced using offshore wind power, offshore production is economically advantageous, and for long-distance transport, liquefying the hydrogen and delivering it directly to the point of demand is an efficient option. In this study, a conceptual design was developed for an offshore liquefied hydrogen production facility capable of producing liquefied hydrogen at sea using offshore wind power. For the conceptual design, (1) the facility requirements were analyzed, (2) systems capable of satisfying those requirements were defined, and (3) an appropriate facility concept was selected through system analysis. Several system configurations and capacities were proposed, and the optimal configuration and capacity were identified through a comparative analysis of economic feasibility, space requirements, and operational stability. Furthermore, a sensitivity analysis was conducted on the key assumed variables. Although the results of this study involve various uncertainties because they were derived at an early stage of design, they are expected to provide important foundational data for the future realization of offshore liquid hydrogen production facilities as part of the energy supply system.
