English
This systematic review of 39 studies (2015-2025) on alternative marine fuels synthesizes environmental, economic, technical, safety, and social criteria to map friction points hindering scalable deployment. It recommends shifting to dynamic, phased carbon pricing to address green premiums, highlights a looming human capital bottleneck and two-tier global fleet risk, and provides a strategic fuel-deployment matrix for industry and policymakers.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本の海運業界は国際海運のGHG削減戦略に対応しつつ、代替燃料の選択と投資判断が急務。本レビューの燃料配備マトリクスは、日本企業の脱炭素投資やScope 3対応の参考となり、政策面では炭素価格の動的導入が日本のカーボンプライシング議論に示唆を与える。
In the global GX context
This review addresses the global maritime decarbonization challenge, aligning with IMO's net-zero framework and EU FuelEU Maritime. It offers a comprehensive synthesis that informs international policy on carbon pricing and fuel transitions, and its strategic matrix is valuable for global shipping stakeholders navigating regulatory and investment decisions.

📄 Abstract（原文）
The maritime industry faces an unprecedented challenge to achieve the net-zero emissions goal by or around 2050. While numerous alternative fuels are undergoing intense evaluation, the industry remains trapped in a profound ‘technological deadlock’ driven by the irreconcilable trade-offs of current options, where fuel might offer excellent environmental profiles but fail on economic viability or safety acceptance. This study addresses this uncertainty by systematically reviewing 39 studies published from 2015 to 2025 that evaluated alternative fuels for the shipping industry using various criteria. Unlike traditional reviews, this study employs a horizontal synthesis across environmental, economic, technical, safety, and social criteria. By cross-examining these fragmented dimensions, this study maps the core friction points that prevent the scalable deployment of alternative fuels. The synthesis indicates that the regulatory framework should shift from static measures to dynamic, phased carbon pricing to address the immediate green premium of alternative fuels. Additionally, the analysis points to a looming global human capital bottleneck and a significant geographic risk of a two-tier global fleet. Most significantly, this study consolidates a decade of marine fuel evaluations into a practical, strategic fuel-deployment matrix that provides industry managers and global policymakers with a clear roadmap to overcome decision-making inertia and safely guide the maritime transition.
