本研究は、トルコとハンブルク間の国際海運貨物ルートを対象に、水素コリドー導入の実現可能性をAHPとTOPSISによる多基準意思決定分析で評価した。技術・運用・経済・環境の各要因を統合し、エンジン数や給油停止、港湾近接性などの運用要因が経路適合性を最も左右することを示す。政策目標だけでは水素採用は保証されず、運用要件を踏まえた経路計画が不可欠だと結論づける。
English
This study applies AHP and TOPSIS multi-criteria decision analysis to prioritize international maritime cargo routes between Türkiye and Hamburg for hydrogen corridor deployment. Operational factors such as engine number, refueling stops, and port proximity dominate route suitability over sustainability objectives. The findings suggest policy goals alone are insufficient to drive hydrogen adoption; implementation strategies must integrate operational requirements.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本は水素・アンモニアの国際サプライチェーン構築を進めており、海運分野の脱炭素は経済安全保障と直結する。本稿の経路選定手法は、日本発の水素コリドー計画や港湾整備の優先順位付けに応用可能な示唆を提供する。
In the global GX context
As IMO decarbonization targets tighten, hydrogen corridors are emerging as a key infrastructure question for global shipping. This paper's MCDA framework offers a replicable method for route prioritization that can inform port investment and international hydrogen trade policy beyond the Türkiye–Hamburg case.

📄 Abstract（原文）
Abstract The maritime shipping industry is responsible for approximately 3% of global greenhouse gas emissions. As a result, it faces growing regulatory and environmental pressure to shift towards cleaner alternative fuels. Green hydrogen, produced from renewable sources, is the possible alternative to change the maritime industry, as it represents a zero-emission alternative. Although hydrogen offers significant potential for maritime decarbonization, production costs limit its competitiveness. Considering the limitations, the purpose of this study is to prioritize international maritime cargo routes for hydrogen corridor deployment by assessing the feasibility of decarbonizing maritime cargo shipping routes between Türkiye and Hamburg using a multi-criteria decision analysis framework. Because the evaluation encompasses technical, operational, economic, and environmental factors, MCDA is necessary due to the complexity of the decision-making process. Route 2 is the most practical alternative according to the results of AHP and TOPSIS, mostly because of operational factors including engine number, refueling stops and port proximity. This suggests that while sustainability objectives (such as the Paris Agreement, CBAM) guide the shift, operational concerns play a key role in developing potential hydrogen deployment pathways. Using a simplified comparative emissions framework for route-level assessment, the results indicate that hydrogen-based pathways may contribute to lower-emission maritime transport, although operational and technical factors remain the primary drivers of route suitability. The findings show that policy objectives by themselves are insufficient to guarantee the adoption of hydrogen. It is essential that implementation strategies and route planning take operational requirements into account. Future research should look more closely at the challenges encountered in optimizing routes for the use of hydrogen in maritime transportation.
