Description

Resource-Circulating Integrated Offshore Plant System and Operating Method Thereof of WCOF Development The present invention relates to a technology developed by the World Cultural Organization Foundation (WCOF) to be established in the future, and more specifically, to a resource-circulating marine plant system that integrates the extraction of green hydrogen and hydrogen production based on seaweed biomass, as well as the high value-added processing of marine resources. Recently, hydrogen energy has been attracting attention as a next-generation energy source due to the depletion of fossil fuels and carbon emission issues. However, hydrogen production and storage systems based on conventional technology have the following problems. Hydrogen storage methods using high-pressure tanks pose an explosion risk and require high costs for safety equipment installation. Additionally, land-based hydrogen production systems require large-scale facilities and transmission networks, resulting in very high initial investment costs. Furthermore, there is the issue of handling water electrolysis byproducts; oxygen generated during the electrolysis process is often discarded without being efficiently utilized. Regarding energy storage and continuous operation limitations, continuous hydrogen production is difficult due to the insufficient efficiency and sustainability of Energy Storage Systems (ESS). Finally, concerning marine pollution and underutilized resources, while the ocean is rich in valuable resources such as lithium and magnesium, technologies for their efficient recovery are limited, and simultaneously, the problem of microplastic pollution is severe. Therefore, there is a growing need for an integrated marine system capable of simultaneously achieving energy production and marine ecosystem revitalization through seaweed-based hydrogen production and oxygen recycling. Conventional direct seawater electrolysis methods face environmental and technical limitations, such as corrosion of the electrolyzer and chlorine generation. Furthermore, in the case of large-scale offshore plants, there is a lack of precise control systems capable of integrated management when thousands of modules exhibit varying power generation outputs, and economic synergies are limited due to the simple disposal of byproducts.
