Research Front and Trend Analysis of Hydrogen Based Integrated Energy System by CiteSpace

The research field of hydrogen energy generation, storage and utilization in integrated energy systems has drawn much attention in the past decade. To discover the research front and trend of this hydrogen centered research field, this paper firstly collected relevant publication records from the database of Web of Science, and then analyze and summarize the active research institutes, main disciplines, important publications and most concerned research themes of this research field based on a scholarly literature analysis and visualization software named CiteSpace. The analysis results indicate the vigorous development of the hydrogen centered research field according to annual publications number of this field, and the two most concerned research themes are performance analysis and hydrogen production.
