本研究は、動的ライフサイクル評価とシステムダイナミクスを統合し、アジア・欧州グリーン海運回廊における13種類の代替燃料（アンモニア、メタノール、水素、大豆バイオディーゼル等）の2050年までの移行経路を評価。技術学習曲線を考慮し、気候影響・環境持続性・エネルギー効率・経済性を分析。大豆バイオディーゼルが短期的解決策、2040年以降は電子燃料が主流となる段階的移行を示し、政策設計が燃料転換の軌道を大きく左右することを明らかにした。
English
This study integrates dynamic life cycle assessment with system dynamics to evaluate 13 alternative marine fuels (e.g., ammonia, methanol, hydrogen, soybean biodiesel) for the Asia–Europe Green Shipping Corridor through 2050. Considering technology learning curves, it analyzes climate impacts, environmental sustainability, energy efficiency, and economic feasibility. Results show a phased transition: soybean biodiesel as a near-term solution, electrofuels dominating after 2040. Policy design and regulatory stringency (IMO Net-Zero Framework, EU FuelEU Maritime) significantly shape fuel transition trajectories.

📄 Abstract（原文）
International shipping stands at a pivotal juncture in its decarbonization efforts, yet a comprehensive assessment of viable fuel transition pathways remains scarce. Here we develop a dynamic life cycle assessment framework integrated with system dynamics to evaluate 13 alternative marine fuels (for example, ammonia, methanol, hydrogen and soybean-based biodiesel) for the Asia–Europe Green Shipping Corridor through 2050. The framework incorporates climate impacts, environmental sustainability, energy efficiency and economic feasibility. Under three scenarios (Business as Usual, Most Economical and Maximum Carbon Reduction), this study accounts for key dynamic parameters, including technology learning curves. Results indicate a phased transition: soybean-based biodiesel offers a near-term solution, while electrofuels dominate after 2040. The International Maritime Organization’s Net-Zero Framework progressively narrows regional cost–emission gaps, whereas the European Union’s FuelEU Maritime regulation introduces a cost premium of up to 7.6%. These results indicate that policy design and regulatory stringency substantially shape fuel transition trajectories for maritime decarbonization. Shipping remains almost entirely reliant on fossil fuels, and identifying viable fuel transition pathways under evolving regulations is a key challenge. A study now evaluates 13 alternative marine fuels for the Asia–Europe corridor, revealing phased transitions shaped by policy design and timing.
