本研究は、沿岸海運におけるバイオ燃料、メタノール、アンモニア、水素などの低炭素燃料の導入が環境と経済に与える影響を比較する。ライフサイクルパラメータと限界削減費用を統合した評価モデルを提案し、2050年までのハイブリッド段階的移行シナリオを分析。HFOからBio-LNGやグリーンメタノールへの転換でCO₂・SOx排出は削減されるが、運航コストは増加する。
English
This study compares low-carbon fuels (biofuels, methanol, ammonia, hydrogen) for coastal shipping, integrating life cycle parameters and marginal abatement costs in a model with scenarios to 2050. A hybrid gradual transition from early biofuels to hydrogen/ammonia is proposed. Switching from HFO to Bio-LNG or green methanol reduces CO₂ and SOx emissions but increases operating costs.

📄 Abstract（原文）
Abstract The article presents an interdisciplinary study examining the environmental and economic implications of introducing low-carbon fuels in coastal shipping. The main focus is on the comparison of alternative energy sources - from biofuels and methanol to ammonia and hydrogen - by the criteria of emissions, cost, technical readiness and logistical feasibility. A comprehensive assessment model is proposed that integrates life cycle parameters, marginal abatement cost (MAC) and strategic implementation scenarios until 2050. Particular attention is paid to a hybrid gradual transition scenario that combines early biofuels with a long-term transition to hydrogen and ammonia. The presented results serve as a practical tool for developing decarbonization roadmaps and decision-making in the transport and port sectors. The work has practical implications for public policy, shipowners and investors in the context of the energy transition and climate commitments. The results showed that switching from HFO to Bio-LNG or green methanol reduces CO₂ and SOx emissions, while increasing total operating costs.
