IMOの2050年ネットゼロ規制を背景に、水素・アンモニア・メタノール等の代替燃料とエネルギー技術を船舶タイプ別に技術経済評価した研究。AISデータから各船種のエネルギー・燃料需要を統計化し、技術の将来発展を織り込んで最適解を検討。船主・港湾運営者の意思決定と資源配分に資する知見を提供する。
English
A technoeconomic framework assesses alternative fuels (hydrogen, ammonia, methanol) and energy technologies across diverse vessel types under IMO's 2050 net-zero target. Using AIS data, it derives median energy and fuel demand per vessel subcategory and factors in future technology development. It offers insights for shipowners and port operators on viable energy transition strategies.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
海運は日本の貿易・物流の根幹であり、IMO規制対応は海運大手や造船業の競争力に直結する。本評価は燃料転換の経済性判断を支援し、国内の水素・アンモニア供給網整備や港湾脱炭素化政策とも連動する。
In the global GX context
Shipping decarbonization is central to global net-zero pathways and IMO strategy, intersecting with transition finance and fuel-supply infrastructure. This vessel-segment-specific assessment adds granularity to fleet-level transition planning, complementing TCFD/ISSB-aligned climate risk disclosure for maritime firms.

📄 Abstract（原文）
International Maritime Organization (IMO) regulations target net-zero emissions by 2050 and encourage enhancing ship performance and operational efficiency, thereby promoting the adoption of renewable fuels and clean technologies. It is essential to identify technological pathways which are technically feasible and economically competitive with conventional solutions. Alternative fuels under consideration include hydrogen and its derivatives, such as ammonia and methanol. Nonetheless, the development of a universally applicable solution for maritime application remains unlikely. Various vessel segments exist, each with distinct operational profiles, sailing routes, and onboard requirements, which influence the suitability of different fuels and energy system options. Accordingly, this study develops a technoeconomic assessment framework, to identify alternative solutions for a selected fleet comprising diverse vessel types. AIS (Automatic Identification System) data is used to generate statistics for each subcategory consisting of their median energy and fuel demand. The energy technologies are improving fast and the optimal alternative fuel and energy system solutions might change when looking into the future. Therefore, the technical and economic development of energy technologies are considered in this assessment. This assessment offers insights into viable energy transition strategies and facilitates decision-making for shipowners and port operators, supporting the efficient allocation of resources in the pursuit of a net-zero global fleet.
