Description
In this era of decarbonization, green hydrogen production is a key technology for coping with intermittence of renewable energy and establishing a decentralized energy network. Against the existing studies, such as onshore and offshore platforms, we propose a new concept “nearshore green hydrogen production & liquefaction platform”. This platform has a few advantages over offshore or onshore plants, primarily in the diverse selection of system components. Since the cost is a critical element, and it influences the commercialization of hydrogen production, we first classified system components and estimated the production cost/capacity for each scenario, which is presented here. The analysis was performed in terms of electricity supply, water treatment, electrolyzer, and storage technology. Additionally, it provided production capacity by different ship sizes. Furthermore, we performed conceptual design works for the most desirable case, including 3D model of the ship. For 100 MW scale green hydrogen production, the results showed that the plant can produce 38 TPD of H2 and costs 6-8 $ to produce 1 kg of H2. With this scale we would be able to install the same at Aframax. Based on this study, KENTECH & HD Hyundai group got AiP (Approval in Principle) from ABS and can provide options that meet the requirements of the customers.
