本論文は、鉄道用ディーゼル機関車における再生可能ディーゼル燃料の技術的適合性を比較分析する。水素化植物油由来のパラフィン系燃料、FAMEバイオディーゼル、20%混合燃料、合成パラフィン燃料の4種類を対象に、規格適合性、燃料系統への影響、貯蔵・季節適合性、移行時の要件を整理した。実運用条件（燃料系統故障リスク、貯蔵の困難さ、メンテナンス要件）が燃料選択の決定的要因であることを示し、鉄道事業者向けの実践的な選定ツールを提供する。
English
This paper compares renewable diesel fuels for railway diesel traction, assessing technical suitability of four alternatives: HVO paraffinic diesel, FAME biodiesel, 20% blend, and synthetic paraffinic diesel. It presents compliance with standards, fuel-system compatibility risks, storage and seasonal issues, and transition requirements. The study concludes that practical operating conditions—such as risk of fuel-system failures, storage difficulty, and maintenance needs—are decisive for fuel selection. A summary table serves as a practical tool for railway operators planning decarbonization on non-electrified sections.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本では鉄道の非電化区間（ローカル線等）でのディーゼル車両の脱炭素化が課題であり、本論文の燃料選定フレームワークは、JR各社や第三セクター鉄道が水素化植物油（HVO）等の導入を検討する際の参考となる。また、SSBJ開示やScope 1排出削減目標の達成に向けた具体的な対策の一つとして位置づけられる。
In the global GX context
Globally, the paper contributes to the decarbonization of diesel rail traction, a segment often overlooked in transport transition studies. It provides a practical framework for fuel selection that can inform operators in the EU and beyond, aligning with the EU's Fit for 55 and the shift to renewable fuels. The comparative analysis supports transition planning for non-electrified rail corridors, relevant to ISSB-aligned disclosure of Scope 1 emissions reduction strategies.

📄 Abstract（原文）
The article is devoted to a comparative analysis of renewable diesel fuels. The aim of the study is to identify technically suitable classes of renewable diesel fuels for use in existing traction diesel engines and to systematize the constraints that determine the feasibility of their implementation. Four alternatives were considered: drop-in paraffinic diesel fuel produced by hydrotreating vegetable oils and fats, biodiesel based on fatty acid methyl esters, a biodiesel–diesel blend with a 20 % biocomponent share, and synthetic paraffinic diesel fuel. For each alternative, the technical application framework is presented, including compliance with standards, typical fuel-system compatibility risks, storage and seasonal suitability issues, as well as requirements for transition operations and fuel quality control. A summary table of requirements and constraints for each fuel type was compiled. The table can be used by railway operators as a practical tool for preliminary fuel selection and for planning the transition on non-electrified sections within the European Union–Lithuania–Ukraine corridor. The study shows that, for fuel selection in rail applications, the decisive factors are practical operating conditions: whether the risk of fuel-system failures increases, whether fuel storage becomes more difficult, and whether additional maintenance requirements arise. For fuels containing a biodiesel component, the main issues relate to storage and fuel cleanliness: water ingress can lead to biological contamination and sediment formation, which may clog filters and disrupt the operation of the fuel injection system. For paraffinic fuels, the main focus is on batch quality and on switching to a different fuel type: key fuel properties must be verified and the compatibility of seals, hoses, and gaskets in the fuel system of the existing fleet must be checked. As a practical outcome, it is determined that, during preparation for implementation, the following should be monitored at a minimum: the presence of water and contaminants, cold-weather operability and deposit formation, stability during storage, as well as parameters that affect the operation of the fuel system and filters. This summary makes it possible to discard options with a high risk of downtime and to establish a basis for further comparison of alternatives by environmental and economic indicators in phased decarbonization programs for diesel traction.
