Cui, Y.; Xu, D.Y.; Liu, Z.L., and Ross, D., 2020. Global research and trends in renewable energy: Ocean waves, tidal energy and offshore wind. In: Malvárez, G. and Navas, F. (eds.), Global Coastal Issues of 2020. Journal of Coastal Research, Special Issue No. 95, pp. 1485-1489. Coconut Creek (Florida), ISSN 0749-0208.

The purpose of this study is to reveal the research trends of scientific outputs on marine renewable energy from ocean for the past 30 years and provide a potential guide for future research. A method of scientometric analysis was performed, based on the online version of the Web of Science and Scopus from 1990 to 2019. The authors evaluated the publication types, source countries, journals, the patterns of publication outputs, most cited articles, most-productive authors, institutional distributions, subject categories, high-frequency keywords in the 1,246 publications of marine renewable energy in total. The research results show that the general most concerned topics of are “renewable energy” “wave energy” “marine renewable energy” “ocean energy” and “tidal energy”, but the bioenergy has increasingly attracted more attention.
