Abstract

Hydrogen production from offshore wind power is one of the ways to solve the problem of consumption. Through the comparative analysis of electrolytic, hydrogen storage and transportation technology suitable for offshore wind, taking an offshore wind farm in eastern Guangdong province of China as an example, according to four cases of high-voltage AC transmission, onshore centralized hydrogen production, offshore centralized hydrogen production + submarine hydrogen pipeline transportation, offshore centralized hydrogen production + LOHC-FPSO + ship transportation, the economy of each case is analyzed under different offshore distances and different hydrogen prices, and it is concluded that the cost of offshore wind power is very sensitive to offshore distance. In that three hydrogen production cases, under the condition that the price of hydrogen is 25 CNY/kg, when the offshore distance exceeds about 180 km, it is difficult to make profits, and it is not suitable for hydrogen production. When the offshore distance is less than 80 km, offshore wind power has more advantages in producing hydrogen on land. When the offshore distance exceeds about 80 km, case 3 is lower. When the offshore distance exceeds about 150 km, case 2 and case 3 will be superior to the case 1. When the benchmark hydrogen price is 25 CNY/kg, the economy of each case is poor.

不同情况下海上风电制氢、储氢和运氢的技术和经济分析：广东案例研究

海上风电制氢是解决消纳问题的途径之一。通过对适用于海上风电的电解、储氢和运输技术的比较分析，以我国粤东某海上风电场为例，按照高压交流输电、陆上集中制氢、海上集中制氢+海底氢气管道运输、海上集中制氢+LOHC-FPSO+船舶运输四种情况，分析了不同离岸距离和不同氢气价格下各情况的经济性，得出海上风电成本对离岸距离非常敏感的结论。在这三种制氢案例中，在氢气价格为 25 元/千克的条件下，当离岸距离超过 180 千米左右时，很难盈利，不适合制氢。当离岸距离小于 80 千米时，海上风电在陆地制氢方面更具优势。当离岸距离超过约 80 千米时，情况 3 较低。当离岸距离超过约 150 千米时，情况 2 和情况 3 将优于情况 1。当基准氢价为 25 元人民币/千克时，每种情况的经济性都较差。

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.
