液体水素(LH2)は航空分野の脱炭素化に向けた有望な選択肢だが、体積エネルギー密度の低さや極低温貯蔵が機体設計に大きな変更を迫る。米空軍のProject SuntanからAirbusやH2FLYの実証まで、水素燃焼・燃料電池・極低温貯蔵技術が進展している。実現には拡大胴体や分散推進、ブレンデッドウィングボディ等の新設計に加え、空港インフラ・認証基準・低炭素水素供給が不可欠だと論じる。
English
Liquid hydrogen (LH2) offers a promising route to decarbonize aviation, but its low volumetric energy density and cryogenic storage demand major aircraft redesign. Historical programs like Project Suntan and current efforts by Airbus and H2FLY are advancing combustion, fuel-cell propulsion, and cryogenic storage. Realizing LH2 flight will require clean-sheet architectures, airport infrastructure, certification standards, and reliable low-carbon hydrogen supply.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本では水素基本戦略や航空脱炭素の議論が進むが、本稿は機体設計・空港インフラ中心で、SSBJや有報開示との直接接点は乏しい。ただし航空分野のScope 3排出削減や水素サプライチェーンを検討する日本企業にとって技術動向の参考になる。
In the global GX context
Globally, aviation decarbonization is increasingly tied to transition finance and ISSB/CSRD disclosure of hard-to-abate sector pathways. This paper adds technical context on LH2 aircraft architecture and infrastructure, useful for investors and policymakers assessing the credibility of hydrogen aviation roadmaps.

📄 Abstract(原文)
Liquid hydrogen (LH2) represents a promising pathway toward reducing aviation’s dependence on conventional hydrocarbon fuels, but its physical and operational characteristics require substantial changes to aircraft design. Although hydrogen provides significantly greater specific energy by mass than conventional jet fuel, its low volumetric energy density and cryogenic storage temperature create challenges involving tank volume, insulation, structural integration, fuel distribution, thermal management, and aircraft center of gravity. Historical programs such as the U.S. Air Force’s Project Suntan demonstrated both the feasibility and complexity of hydrogen-powered flight, while contemporary research and demonstrations by organizations including Airbus and H2FLY are advancing hydrogen combustion, fuel-cell propulsion, and cryogenic storage technologies. Future hydrogen aircraft may therefore incorporate enlarged fuselages, distributed propulsion, box-wing or blended-wing-body configurations, and other clean-sheet designs optimized specifically for LH2. Successful implementation will additionally require extensive airport infrastructure, specialized refueling systems, certification standards, and reliable low-carbon hydrogen production. Liquid hydrogen consequently represents not merely an alternative aviation fuel, but a technological transition capable of reshaping aircraft architecture, propulsion systems, airport operations, and the broader aviation energy infrastructure.
