本レビューは、LNG、バッテリー、水素燃料電池の3つの推進技術を、環境影響、技術成熟度、コスト、導入動向などの観点から比較。2023年時点で計1,053隻の実運航データを分析し、LNGは過渡的解決策、バッテリーは短距離航路で優位、水素燃料電池は成長潜在性が高いがコストと水素供給が課題と結論付けている。IMOの脱炭素目標達成には、各地域・航路に応じた差別化戦略が必要と示唆。
English
This review provides a data-driven comparative analysis of LNG, battery, and hydrogen fuel cell technologies for maritime decarbonization, analyzing 1,053 ships in operation as of 2023. It finds that LNG serves as a transitional solution constrained by methane slip, battery dominates short-sea applications in Europe but faces charging infrastructure issues, and hydrogen fuel cells have the highest growth potential but remain limited by cost and fuel availability. The study highlights the need for differentiated strategies aligned with IMO targets.

📄 Abstract（原文）
This review provides a data-driven comparative review of liquefied natural gas (LNG), battery, and hydrogen fuel cell technologies as emerging propulsion systems for sustainable maritime operations. Drawing on ship registry databases, industry reports, and academic studies, this article analyzes 445 LNG-powered, 572 battery-powered, and 36 fuel cell-powered ships in operation as of 2023. By systematically comparing these technologies in terms of environmental impact, operational scope, technological maturity, infrastructure development, cost-effectiveness, and adoption trends, the review reveals critical tradeoffs and region-specific trajectories. Notably, LNG-powered ships serve as a transitional solution but are constrained by methane slip and fossil fuel dependency. Battery-powered ships dominate short-sea applications in Europe yet face challenges related to charging infrastructure and life-cycle emissions. Hydrogen fuel cell-powered ships exhibit the highest projected growth rate but remain limited by cost and hydrogen availability. The review identifies key technical and policy gaps for each energy type and offers insights into future integration pathways aligned with IMO decarbonization targets. This study contributes a comprehensive fleet-level comparative assessment across these three energy types and highlights the need for differentiated strategies in maritime energy transition.
