Bibliometric Analysis of Explosion Risk Research in the New Energy Industry: Hotspots, Frontiers, and Regional Trends (2008–2024)

To elucidate the current research landscape and application status and to identify emerging development trends in explosion risk within the new energy industry, a bibliometric analysis was conducted using literature retrieved from the Web of Science Core Collection (SCI-EXPANDED, SSCI, CPCI-S) between 2008 and 2024. Employing co-occurrence analysis, cocitation analysis, and keyword burst detection, this study maps the knowledge structure and evolutionary dynamics of explosion risk research in the sector. The results indicate that major source journals by publication volume in this domain include Energies, Sustainability, and the Journal of Cleaner Production. Major research hotspots encompass machine learning-driven risk prediction, life-cycle assessment (LCA), thermal runaway mitigation in lithium-ion batteries, and safety innovations for high-pressure CO2 storage. Emerging frontiers are focused on data-driven life-cycle risk management and integrated materials–structure–process safety technologies. Regionally, Asia leads in energy storage and protection strategies, Europe emphasizes life-cycle and system performance issues, and North America prioritizes process safety and numerical simulation. This work systematically constructs a knowledge map of explosion risks across multiple domains─including hydrogen storage, battery energy storage, and carbon capture─and reveals significant regional variations in technological emphasis, methodological approaches, and collaborative patterns.
