Imprudent fossil fuel use for getting energy caused serious environmental problems making us necessary to seeking for alternative energy sources which are renewable and sustainable. Using wind energy is currently considered as one of feasible renewable energy sources, however, the problem of noise pollution from the sweep of turbine blades should be solved. As a feasible solution for the noise pollution problem, the construction of wind farms offshore is currently considered. In addition, many factors can change the onshore wind speed, while offshore wind has a higher wind speed and consistency, which leads to higher energy efficiency. However, the remained intermittency of wind energy makes storage media such as H₂ necessary, thus, the construction of an offshore wind base H₂ production system can be required for protecting the energy security. In this study, a comparative economic analysis is conducted to verify feasible equipment placements of offshore wind-based H₂ production systems in various possible cases with different electrolyzer types, wind speeds, and offshore distances. An optimization study for 4 case scenarios with different regions, offshore lengths, and kinds of electrolyzers, was preliminarily conducted to find several placements that are economically optimal in common. For the optimization, a mixed-integer programming tool in Python was used, and as a result, three absolutely economical placements were selected. Then, the comparative economic analysis with considering the selected three cases was conducted indicating the most feasible placement according to the considered offshore length and wind speed, and costs ranged from 1.64 to 4.46 $ kgH₂⁻¹. From the optimal cases for considered regions (Ulsan, Magallanes), the system using alkaline electrolyzer can achieve the feasible prices for both regions, while using other types stay in ranges of the current green H₂ produced by electrolysis.

轻率地使用化石燃料获取能源造成了严重的环境问题，使我们有必要寻求可再生和可持续的替代能源。使用风能目前被认为是可行的可再生能源之一，但是，涡轮叶片扫掠产生的噪声污染问题需要解决。作为噪声污染问题的可行解决方案，目前正在考虑建设海上风电场。此外，许多因素可以改变陆上风速，而海上风具有更高的风速和一致性，从而导致更高的能源效率。然而，风能的剩余间歇性使得H ₂等存储介质成为必需，因此，海上风电基地H _2的建设保障能源安全需要生产系统。在这项研究中，进行了比较经济分析，以验证海上风电 H _{2的可行设备布置}不同电解槽类型、风速和离岸距离的各种可能情况下的生产系统。初步对不同地区、离岸长度、电解槽种类的4个案例场景进行了优化研究，找到了几个共同的经济最优布置方案。为了优化，使用了 Python 中的混合整数编程工具，结果，选择了三个绝对经济的布局。然后，对选定的三种情况进行比较经济分析，根据考虑的离岸长度和风速确定最可行的布置，成本范围为 1.64 至 4.46 $ kgH ₂ ⁻¹. 从所考虑地区（蔚山、麦哲伦）的最佳案例来看，使用碱性电解槽的系统可以实现两个地区的可行价格，而使用其他类型的系统则停留在当前电解生产的绿色 H _{2的范围内。}
