大规模绿色制氢（LGHP）的发展为促进海上风电场（OWF）的快速发展创造了商业机会。本研究调查了LGHP在OWF站点的共同定位是否改善了OWF在2050年潜在电网容量瓶颈下的经济前景。使用测得的OWF年发电量系列和成本估算，结合海上工程经验，研究了八种情况：i）两种基本情况：2吉瓦的OWF与HVAC和HVDC输电基础设施表明，平准化电力成本（LCOE）增加，以及ii）六个LGHP共址案例表明，当LGHP容量从20%增加到20%时，计算的氢的平准化成本（LCOH）降低到50%，和100%的2吉瓦。此外，研究的三个经济改进因素是：i）利用现有的天然气管道将LCOH减少7.5%，ii）海上客户的氢气将“不去”项目改为“去”，以及iii）从2 GW扩大到4 GW将LCOH减少17%。该研究表明，LGHP共址在维持OWF满负荷生产方面是有效的，但具有较高的风险，包括i）LGHP共址在OWF的安全性，ii）覆盖更多操作条件的高成本以及iii）使用高波动的OWF功率运行LGHP操作。建议进一步研究和开发LGHP共址技术。
Advances in large-scale green hydrogen production (LGHP) create commercial opportunities for enhancing rapid offshore wind farm (OWF) development. This study investigates whether LGHP co-location at OWF sites improves those OWF's economic outlooks under potential electrical grid capacity bottlenecks towards 2050. Eight cases have been studied using measured annual OWF power production series and cost estimation integrated with offshore engineering experience: i) two base cases: 2 GW OWFs with HVAC and HVDC transmission infrastructure showing that the levelized cost of electricity (LCOE) increases, and ii) six LGHP co-location cases demonstrating that the calculated levelized cost of hydrogen (LCOH) reduces when the LGHP capacity increases from 20% to 50%, and 100% of 2 GW. Furthermore, three economic improvement factors studied are: i) utilizing existing gas pipelines reducing LCOH by 7.5%, ii) hydrogen for offshore customers changing" no-go" projects to" go", and iii) scaling-up from 2 to 4 GW reduced the LCOH by 17%. This study shows that LGHP co-location is effective at maintaining OWF full production, but has higher risks including i) LGHP co-location safety at OWFs, ii) high costs to cover more operational conditions and iii) running LGHP operations using high, fluctuating OWF power. Further R&D of LGHP co-location are recommended.
