グリーン水素技術に関する9545件の論文(2010-2024年)をCiteSpaceで分析。研究の爆発的成長、コア・ペリフェリー型国際共著構造、3段階のキーワード遷移(基礎電解→機構最適化→システム統合)を特定。国際協力の課題と知識断片化を指摘し、今後の重点分野(電極触媒、システム最適化、技術経済統合)を提示。
English
This scientometric analysis of 9,545 publications on green hydrogen technology (2010-2024) reveals explosive growth driven by policy, a core-periphery collaboration network with China leading in volume but European and Middle Eastern countries as brokers, and a three-phase keyword evolution from fundamental electrolysis to system integration. It identifies challenges in international cooperation and knowledge fragmentation, and highlights emerging priorities in electrocatalysis and techno-economic integration.

📄 Abstract（原文）
Green hydrogen technology, which produces hydrogen via water electrolysis powered by renewable energy, has emerged as a critical pathway toward carbon neutrality and become a global research hotspot. However, systematic mapping of its research evolution and knowledge structure remains insufficient. This study employs CiteSpace (v6.3.R2) to conduct scientometric analysis of 9545 Web of Science publications (2010–2024), examining publication trends, collaboration networks, co-citation relationships, and keyword evolution. Key findings include: (1) explosive growth from 43 publications (2010) to 3275 (2024), driven by escalating policy commitments; (2) a core-periphery collaboration structure in which China leads in volume but Germany, France, and Saudi Arabia occupy central brokerage positions; (3) moderate modular structure in the co-citation network with nascent cross-cluster convergence since 2020; and (4) a punctuated three-phase keyword transition from fundamental electrolysis research (2010–2016), through mechanistic optimisation (2017–2020), to system integration and deployment (2021–2024). These findings advance scientometric analysis from descriptive mapping to theoretical explanation, identifying challenges in international cooperation and knowledge fragmentation while charting emerging priorities in electrocatalysis, system-level optimisation, and techno-economic integration.
