本レビューは、e-diesel、e-petrol、e-OME3-5の旅客車への適用可能性を調査。生産経路、燃料特性、既存ICEV互換性、LCA研究を体系的にレビュー。気候変動緩和効果は電力の炭素強度に強く依存し、系統電源ベースでは化石燃料と比較して優位性が限定的である。
English
This literature review examines electrofuels (e-diesel, e-petrol, e-OME3-5) for passenger car decarbonization, covering production pathways, fuel properties, ICEV compatibility, and a systematic review of LCA studies. Climate benefits are realized only under low-carbon electricity (break-even ~123 gCO2eq/kWh); grid-mix scenarios rarely achieve this.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本政府は2035年以降の新車販売で電動車のみ義務化する方針だが、e-fuelは既存ICEVのゼロエミッション化への過渡的技術として注目。本レビューはe-fuelの環境性能が電力炭素強度に強く依存することを示し、日本の電源構成（再生可能エネルギー比率）が鍵となる。
In the global GX context
The EU is considering e-fuels as an exemption to the 2035 ICE ban. This review underscores that e-fuels' climate benefits depend on low-carbon electricity, which has implications for global fuel policy and LCA harmonization.

📄 Abstract（原文）
Electrofuels (e-fuels) have been proposed within the carbon dioxide (CO 2 ) emissions policy framework of the European Union as an option to enable the continued registration of new internal combustion engine vehicles (ICEVs) beyond 2035. However, they remain an emerging technology, and comprehensive assessments for light-duty passenger cars jointly addressing fuel properties and environmental performance remain limited. This study examines e-diesel, e-petrol, and e-OME 3-5 , providing an overview of production pathways, properties, and expected compatibility with the existing ICEV fleet, alongside a systematic review of Life Cycle Assessment (LCA) studies. Impact categories beyond climate change are often overlooked, being evaluated only in 7 of the 19 selected studies. Climate change mitigation potential varies widely, with well-to-wheel emissions ranging from 4 to 564 g CO2,eq /km for e-diesel, 8–531 g CO2,eq /km for e-petrol, and 10–759 g CO2,eq /km for e-OME 3-5 . This dispersion reflects differences in technological and methodological assumptions; however, carbon intensity of electrical energy consistently emerges as dominant driver. Climate benefits over fossil fuels occur only under low-carbon electricity scenarios, with a break-even value of approximately 123 g CO2,eq /kWh, a condition rarely met by grid mix-based configurations. Greater primary data availability and harmonised LCA frameworks would improve the reliability of environmental performance estimates and cross-study comparability.
