EVOLUTION OF HYDROGEN ENERGY RESEARCH IN CHINA BASED ON BIBLIOMETRIC ANALYSIS
Hydrogen energy is a critical component of the emerging clean energy era and a major contributor to the development of a low-carbon economy.To understand the progress of hydrogen energy research in China over the past ten years,hydrogen energy-related journal papers and patents published between 2013 and 2022 were analyzed,as recorded in the China National Knowledge Infrastructure(CNKI)database.Using VOSviewer and other software,bibliometric and scientific knowledge mapping analyses of annual publishing trends,published journal distributions,funding situations,research hotspots,publishing institutions,author cooperation networks and patent inventors were carried out.Additionally,the policy factors underlying the changes in research hotspots and annual publishing volume were examined,based on a comprehensive analysis of the current historical context.Analysis offered a comprehensive demonstration of hydrogen energy research in China over the past decade,providing insights from various perspectives into its research context and development status.Lastly,the process of developing standard specifications and policy reports in the field of hydrogen energy in China were outlined and various methods to facilitate the advancement of research on hydrogen energy based on a national strategic standpoint were proposed.
