本研究は、EUのエネルギーシステムモデルを用いて、E-バイオ燃料（再生可能水素をバイオマス変換に添加し、生物起源炭素を有効活用する燃料）が厳しい排出目標達成に費用対効果が高いことを示した。特にバイオマスが限定的で化石燃料が不適格な場合、システム総コストを最大2.7%、液体燃料コストを10%以上削減する。E-バイオ燃料はバイオマス、水素、炭素貯蔵の不確実性や政策変動に対するヘッジとして有望である。
English
Using a European energy system model, this paper finds that e-biofuels—produced by adding renewable hydrogen to biomass conversion—are cost-effective for meeting stringent emissions targets, especially when biomass is limited and fossil fuels are ineligible. They reduce total system costs by up to 2.7% and liquid fuel costs by over 10%. E-biofuels serve as a hedge against uncertainties in biomass, hydrogen, and carbon storage availability.

日本のGX文脈において
本論文はEUの政策・モデルに基づくが、日本でも航空・海運など電化困難セクターの脱炭素燃料戦略に示唆を与える。特に、限られたバイオマスを最大限活用するE-バイオ燃料のコスト優位性は、日本のエネルギー計画やSAF導入検討において参考となる。
In the global GX context
This paper provides crucial evidence for global renewable fuel policy by demonstrating the cost-effectiveness of e-biofuels under stringent decarbonization targets. It informs ISSB, EU RED, and similar frameworks by highlighting e-biofuels as a complementary solution to synthetic e-fuels, particularly when carbon sequestration capacity is limited.

📄 Abstract（原文）
Renewable liquid fuels are essential for achieving emissions targets for hard-to-electrify sectors such as aviation and shipping. While biofuels and synthetic e-fuels have been well-studied, e-biofuels, produced by adding renewable hydrogen to biomass conversion to better utilise the biogenic carbon, remain understudied and lack a clear role in EU fuel regulations. In this paper, using a sector-coupled European energy system model, we find that e-biofuels are cost-effective to meet stringent emissions targets if biomass availability is limited and fossil fuels are ineligible, either due to limited carbon sequestration capacity or to high renewable fuel mandates. By directly increasing utilisation of biogenic carbon instead of synthesising fuels based on captured $CO_2$, there are savings from fuel production and carbon capture that reduce total system costs by up to 2.7% and liquid fuel costs by more than 10%. Our results highlight the role of e-biofuels as a potential hedge against uncertainty in biomass, hydrogen, and carbon storage availability, as well as evolving policy implementation.
