日本語
本論文は、水素をエネルギーキャリアとして捉え、生産経路・技術成熟度（TRL）・課題・展望を体系的文献レビューで統合的に整理した。脱炭素への貢献は生産経路に強く依存し、現状は化石燃料由来が主流である一方、グリーン水素の排出削減ポテンシャルは大きい。生産・貯蔵・輸送・利用のバリューチェーン全体の制約が大規模展開を妨げるが、技術進歩と適切な政策が普及を後押しし得ると結論づける。
English
This study synthesizes hydrogen's role as an energy carrier through a systematic literature review, integrating production pathways, Technology Readiness Levels, challenges, and prospects. Decarbonization contribution depends heavily on the production pathway; current supply remains fossil-based, though green hydrogen offers significant emission-reduction potential. Value-chain constraints in production, storage, transport, and utilization limit large-scale deployment, but technological advances and supportive policies may enable consolidation.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本は水素基本戦略やグリーン成長戦略で水素を重点領域とし、福島水素エネルギー研究フィールドなど実証が進む。本論文は生産経路依存性とバリューチェーン制約を整理し、日本企業の水素調達・投資判断や政策設計の参照枠を提供する。
In the global GX context
Hydrogen is central to global net-zero pathways and transition finance, with the EU's REPowerEU, US IRA hydrogen credits, and Japan's Basic Hydrogen Strategy shaping investment. This review's emphasis on TRL and pathway-dependent decarbonization helps investors and policymakers assess green hydrogen credibility against the expectation–reality gap.

📄 Abstract（原文）
In the pursuit of decarbonization and energy sustainability, hydrogen has emerged as an energy carrier with potential relevance to the energy transition. Its importance derives from advantages such as clean combustion, high energy density, and versatility compared with conventional fuels. Although numerous studies have investigated hydrogen production technologies and its role as the “energy of the future,” integrated analyses addressing production pathways, Technology Readiness Levels (TRLs), and its potential influence on the global energy sector remain limited. This study provides a descriptive synthesis of hydrogen as an energy carrier based on systematic bibliographic procedures and inductive and deductive analysis, examining its role in the energy transition, indicators of its consolidation, challenges, limitations, and prospects. The findings indicate that the contribution of hydrogen to decarbonization strongly depends on its production pathway. While green hydrogen offers significant potential for reducing greenhouse gas emissions, current hydrogen production remains predominantly dependent on fossil-based pathways. In addition, challenges throughout the hydrogen value chain, particularly in production, storage, transportation, and utilization, constrain overall efficiency and large-scale deployment. Technological advances and appropriate government policies may, however, support its consolidation as a key component of the energy transition.
