Abstract

The South Korean government has an ambitious policy to roll out hydrogen-powered vehicles across the country with 2000 hydrogen refueling stations (HRSs) infrastructure by 2050. However, the country currently lacks sufficient HRS infrastructure. In this context, this study proposes and investigates the technoeconomic feasibility and performance assessment of an optimal hybrid renewable energy system integrated with a vanadium redox flow battery for on-site hydrogen production. The system is designed to refuel a fleet of 20 fuel cell electric vehicles at seven South Korean locations with distinct climates. Based on the typical daily hydrogen and electric load profile of the HRS, the capital expenditure, net present cost, operation expenditure, levelized cost of hydrogen and levelized cost of energy were estimated to be, $5.95 - $13.2 M, $8.93 - $19.4 M, 82,670–202,184 $/yr, 8.77–19.1 $/kg and 2.1–4.58 $kWh, respectively.

用于现场制氢的太阳能光伏-风力涡轮机混合系统：韩国气候条件下加氢站的技术经济可行性分析

韩国政府制定了一项雄心勃勃的政策，计划到 2050 年在全国范围内推广氢动力汽车，并建立 2000 个加氢站（HRS）基础设施。然而，韩国目前缺乏足够的加氢站基础设施。在此背景下，本研究提出并研究了一种最佳混合可再生能源系统的技术经济可行性和性能评估，该系统与钒氧化还原液流电池集成，用于现场制氢。该系统设计用于为韩国七个不同气候条件下的 20 辆燃料电池电动汽车加氢。根据 HRS 的典型日氢气和电力负荷情况，资本支出、净现值成本、运营支出、氢气平准化成本和能源平准化成本估计分别为 595-1,320 万美元、893-1,940 万美元、82,670-202,184 美元/年、8.77-19.1 美元/千克和 2.1-4.58 美元/千瓦时。

期刊介绍： The objective of the International Journal of Hydrogen Energy is to facilitate the exchange of new ideas, technological advancements, and research findings in the field of Hydrogen Energy among scientists and engineers worldwide. This journal showcases original research, both analytical and experimental, covering various aspects of Hydrogen Energy. These include production, storage, transmission, utilization, enabling technologies, environmental impact, economic considerations, and global perspectives on hydrogen and its carriers such as NH3, CH4, alcohols, etc. The utilization aspect encompasses various methods such as thermochemical (combustion), photochemical, electrochemical (fuel cells), and nuclear conversion of hydrogen, hydrogen isotopes, and hydrogen carriers into thermal, mechanical, and electrical energies. The applications of these energies can be found in transportation (including aerospace), industrial, commercial, and residential sectors.
