Abstract

Maritime transportation has experienced significant growth since 1990, with its use surging by over 150%, constituting approximately 90% of global transportation for goods transfer. However, the overwhelming majority of the global maritime fleet still relies heavily on fossil fuels, leading to substantial greenhouse gas (GHG) emissions. To address these challenges, the International Maritime Organization (IMO) has implemented regulations and initiatives to mitigate CO2 and GHG emissions from shipping. Among these, the use of hydrogen emerges as a promising option for achieving sustainable decarbonization of maritime transportation. This paper investigates grey, blue, and green hydrogen production methods in the context of the shipping industry. Through strength, weakness, opportunity, and threat (SWOT) analysis combined with Analytical Hierarchy Process (AHP) methodology, the strengths, weaknesses, opportunities, and threats associated with each hydrogen type are prioritised and evaluated. The findings reveal nuanced shifts in strategic considerations during transitions between hydrogen types, highlighting the importance of regulatory support and technological advancements in driving the transition towards cleaner hydrogen production methods. The study concludes by emphasizing the need for strategic planning and technological advances to overcome challenges and capitalize on opportunities for a more sustainable and resilient energy future in maritime transportation.
不同颜色氢气用于航运脱碳的 SWOT-AHP 分析
自 1990 年以来,海上运输经历了大幅增长,其使用量激增了 150% 以上,约占全球货物运输的 90%。然而,全球绝大多数海运船队仍然严重依赖化石燃料,导致大量温室气体(GHG)排放。为应对这些挑战,国际海事组织(IMO)实施了相关法规和举措,以减少航运业的二氧化碳和温室气体排放。其中,氢的使用成为实现海运可持续脱碳的一个有前途的选择。本文以航运业为背景,研究了灰色、蓝色和绿色制氢方法。通过优势、劣势、机会和威胁(SWOT)分析,结合层次分析法(AHP),对每种制氢方法的优势、劣势、机会和威胁进行了优先排序和评估。研究结果揭示了氢气类型过渡期间战略考虑因素的细微变化,强调了监管支持和技术进步在推动向清洁氢气生产方法过渡方面的重要性。研究最后强调了战略规划和技术进步的必要性,以克服挑战并抓住机遇,在未来的海上运输中实现更可持续和更具弹性的能源。
