The Knowledge Map of Marine Energy

In order to analyze the research hotspots of marine energy, the Citespace III software was used to visually analyze marine energy. The database was collected on the criteria of marine energy as the keyword, and time span extended from 2007 to 2016 on the basis of the "Web of Sciencetm core collection database". The scientific knowledge maps analysis of marine energy has been conducted based on the Citespace III software, and analyzes the active countries/regions, institutions and research hotspots in related research fields. Active countries/regions, institutions and research hotspots of relevant research areas have been studied, and University of Chinese Academy of Sciences is at the first place of whole research institutions in marine energy field. Keywords co-occurrence analysis results show that coast, corrosion, kinetics, evolution and sediments have the highest centralities which are the focal keywords in marine energy research field. The results of the co-citation analysis show that wave energy, tidal stream energy, tidal stream turbines, and the microalgae biofuels are the hotspots in marine energy research field.
