Renewable Energy Application Research Using VOSviewer software: Bibliometric Analysis

Abstract

This study analyzes renewable energy and clean technology research trends through a bibliometric approach. The visualization results show that hydrogen and fuel topics dominate the literature, focusing on green hydrogen technology and fuel cells. Catalyst and stability topics are also frequently discussed, emphasizing the importance of developing materials to support the stability of hydrogen energy systems. In addition, biomass is a crucial concern in renewable energy research. The findings from the table reveal that energy systems and models have strong links with other topics, such as networks and supply, indicating a focus on developing integrated energy systems and smart grids. In conclusion, hydrogen technology, biomass conversion, and material innovation play a crucial role in the transition to clean and sustainable energy, although challenges related to stability and cost remain.
