本研究は、韓国・米国間のグリーン海運回廊における代替燃料の実現可能性を評価した。16,000TEU級コンテナ船を対象に、HFO、LNG、メタノール、バイオディーゼルの4シナリオを比較し、LNGがCO2排出量と総運航コストで最も優れることを示した。メタノールもCO2削減効果があるが経済性はLNGに劣る。統合的評価の重要性を強調し、将来はWell-to-wake排出量の考慮が必要としている。

This study assesses the feasibility of alternative fuels for a green shipping corridor on the Korea-U.S. route. For a 16,000-TEU container ship, LNG shows the lowest CO2 emissions and most favorable total operating cost compared to HFO, methanol, and biodiesel. Methanol reduces CO2 but is less economical than LNG. The study emphasizes integrated assessment and calls for future well-to-wake analysis.

📄 Abstract（原文）
: Green shipping corridors have emerged as a key strategy for maritime decarbonization in response to the International Maritime Organization’s greenhouse gas reduction goals. This study conducted a preliminary feasibility assessment of alternative marine fuel use on the Korea – U.S. route. A 16,000-TEU-class container ship was considered under four fuel scenarios: heavy fuel oil (HFO), liquefied natural gas (LNG), methanol, and biodiesel. Environmental performance was evaluated on the basis of tank-to-wake CO 2 emissions, a voyage-based carbon intensity indicator, and using a simplified assessment based on greenhouse gas fuel intensity, while economic performance was assessed on the basis of fuel costs and estimated regulatory costs. Under the assumptions and target values adopted in this study, LNG exhibited the lowest CO 2 emissions and the most favorable estimated total operating cost. Methanol also reduced CO 2 emissions relative to HFO but showed less favorable economic performance than LNG. These findings highlight the importance of integrated assessments that consider fuel characteristics, operational performance, and regulatory effects when planning green shipping corridors. Future research should incorporate well-to-wake emissions and other relevant greenhouse gases to provide a more comprehensive evaluation of alternative marine fuels.
