電化が難しい航空・海運などの部門では再生可能液体燃料が不可欠である。本研究は欧州のエネルギーシステムモデルを用いて、e-バイオ燃料（バイオマス変換に再生可能水素を追加し、バイオジェニックカーボンを活用する燃料）が、バイオマス供給制約や化石燃料不適格条件下で排出目標をコスト効率的に達成できることを示した。総システムコストを最大2.7%、液体燃料コストを10%以上削減し、バイオマス・水素・炭素貯蔵の不確実性に対するヘッジとしての役割を強調する。
English
Renewable liquid fuels are crucial for hard-to-electrify sectors like aviation and shipping. Using a European energy system model, this paper shows that e-biofuels (produced by adding renewable hydrogen to biomass conversion to utilize biogenic carbon) are cost-effective for meeting stringent emissions targets under limited biomass availability and fossil fuel ineligibility. They reduce total system costs by up to 2.7% and liquid fuel costs by over 10%, serving as a hedge against uncertainties in biomass, hydrogen, and carbon storage availability.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
欧州の規制枠組み（RED等）を前提とした分析だが、日本でも航空・海運の脱炭素が急務であり、バイオマス・水素・CCSの不確実性を考慮した燃料戦略として示唆に富む。ただし国内のバイオマス調達や水素供給インフラの実態に合わせた検討が必要。
In the global GX context
This paper provides a model-based assessment of e-biofuels within the EU regulatory context, highlighting their role as a cost-effective option for hard-to-electrify sectors. It contributes to the global debate on renewable fuel mandates and carbon capture utilization, offering insights for policymakers designing technology-neutral decarbonization pathways.

📄 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.
