Advancements in Hydrogen Storage Vessels: A Bibliometric Analysis

Abstract

This bibliometric study examines the evolution of compressed-hydrogen storage technologies over the last 20 years, revealing exponential growth in research and highlighting key advancements in compressed-hydrogen storage, materials-based solutions and integration with renewable energy systems. The analysis highlights the pivotal role of composite material tanks and the filament-winding process in revolutionizing storage technology. These innovations have enhanced safety, reduced weight and facilitated adaptation for use in automotive and industrial applications. Global research efforts are characterized by substantial international collaboration, spearheaded by a small cohort of highly productive researchers and supported by a broader network of contributors. Notwithstanding the ongoing challenges pertaining to safety considerations and cost scalability, the potential of hydrogen as a clean energy carrier and its role in balancing renewable energy systems serve to reinforce its importance in the transition to sustainable energy.
