本レビューは、微細藻類の水熱液化（HTL）で得られるバイオ原油を、グリーン水素を用いた水素化処理で航空燃料（SAF）へ転換する統合経路を包括的に評価する。藻類培養から改質、水素供給、TEA/LCAまでバリューチェーン全体を連結し、脱酸素・脱窒素の向上と燃料品質改善における再生可能水素の役割を検討する。オンサイト水素生成やコスト・炭素強度低減策も論じ、SAF供給網の強靱化に示唆を与える。
English
This review integrates algae hydrothermal liquefaction (HTL) biocrude upgrading with green hydrogen for sustainable aviation fuel (SAF). It links cultivation, catalytic upgrading, hydrogen-assisted hydroprocessing, and TEA/LCA across the value chain, emphasizing renewable hydrogen's role in deoxygenation and fuel quality. It also assesses cost, carbon intensity, and on-site hydrogen generation for supply-chain resilience.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本では航空分野の脱炭素とSAF国産化が政策課題であり、藻類由来SAFとグリーン水素の統合はエネルギー安全保障と産業競争力に直結する。統合報告書や気候関連開示でSAF調達・水素戦略を説明する企業にとって参考になる。
In the global GX context
Globally, SAF is central to aviation decarbonization under ICAO/CSRD and transition finance frameworks. This review adds value by explicitly linking green hydrogen integration with TEA/LCA assumptions, informing disclosure of Scope 3 aviation emissions and low-carbon fuel pathways.

📄 Abstract（原文）
The increasing demand for sustainable aviation fuel (SAF) is driving the development of integrated pathways for renewable fuel production. Algae-based biocrude produced through hydrothermal liquefaction (HTL) represents a promising route due to the high productivity of microalgae, flexible feedstock utilization, and minimal competition with food resources. This review provides an integrated perspective on algae-HTL-to-SAF pathways by explicitly linking renewable hydrogen supply, fuel upgrading performance, and Techno-economic analysis/Life cycle assessment (TEA/LCA) assumptions across the value chain. This review critically evaluates recent advances in algal cultivation, HTL-based biocrude production, catalytic upgrading, and hydrogen-assisted hydroprocessing for converting algal biocrude into aviation-range fuels. Particular emphasis is placed on the role of green hydrogen, examining how renewable-energy-driven hydrogen production can be integrated into hydrotreatment processes to enhance deoxygenation, denitrogenation, and overall fuel quality. TEA and LCA of algae-to-SAF pathways are also evaluated, highlighting strategies to reduce production costs, lower carbon intensity, and improve life-cycle performance. In addition, the potential for on-site hydrogen generation within algae biorefineries is discussed as a means to increase process efficiency and strengthen supply-chain resilience. By addressing the full value chain from algal cultivation to hydrogen-enabled upgrading, this review provides a comprehensive assessment of recent advances in algal biocrude upgrading and green hydrogen integration for SAF production.
