本レビューは水素および燃料電池技術のバリューチェーン全体を統合的に評価している。製造方法（化石由来+CCS、再生可能電解、廃棄物からの水素）を比較し、効率、炭素強度、成熟度、スケーラビリティなどの指標を用いて最適な経路は地域条件に依存することを示した。システム統合、デジタル最適化、循環経済戦略、標準認証、インフラ計画の重要性を強調している。
English
This review provides an integrated evaluation of hydrogen and fuel cell technologies across the full value chain, comparing fossil-based H2 with and without CCS, renewable electrolysis, and waste-to-H2 pathways. It finds that no single pathway is universally optimal; suitability depends on regional electricity mix, feedstock, storage, and end-use. The study highlights system integration, digital optimization, circular economy, and coordinated infrastructure planning as essential for commercial viability.

In the global GX context
This review is relevant to the global hydrogen push, including the EU Hydrogen Strategy, US Hydrogen Hubs, and IEA Net Zero pathways. It provides a systematic comparison of hydrogen production routes and highlights the need for integrated planning and certification standards, which are critical for scaling up low-carbon hydrogen globally.
👥 読者別の含意
🔬研究者:GX researchers can use this review as a comprehensive benchmark for hydrogen pathway comparison and identify gaps in techno-economic and life-cycle assessment.
🏢実務担当者:Corporate sustainability teams can evaluate which hydrogen supply chain is most viable for their decarbonization targets.
🏛政策担当者:Policymakers should note that no single hydrogen pathway fits all contexts; supportive policies must consider regional energy mix and infrastructure.
📄 Abstract（原文）
Abstract Hydrogen is increasingly recognized as a key energy carrier for low-carbon energy systems because it can support renewable energy storage, industrial decarbonization, clean transport, and distributed power generation. However, large-scale deployment remains constrained by high production costs, storage and distribution losses, infrastructure gaps, fuel-cell durability limitations, and inconsistent sustainability assessment. This review provides an integrated evaluation of hydrogen and fuel cell technologies across the full value chain, including production, storage, distribution, utilization, techno-economic performance, life-cycle impacts, and policy readiness. Fossil-based hydrogen with and without carbon capture, renewable electrolysis, and waste-to-hydrogen pathways are compared using common indicators, including efficiency, carbon intensity, maturity, scalability, and infrastructure dependence. The review shows that no hydrogen pathway is universally optimal; deployment suitability depends on regional electricity mix, feedstock availability, storage route, transport distance, end-use sector, and regulatory support. The study highlights system integration, digital optimization, circular-economy strategies, standard certification, and coordinated infrastructure planning as essential requirements for commercially viable low-carbon hydrogen systems.
