Análise bibliométrica das publicações relacionadas à produção de hidrogênio e fonte solar fotovoltáica

Abstract

The use of renewable energies has attracted interest due to the energy problem that Brazil and the world go through. However, renewable sources, such as solar photovoltaic, are intermittent and the use of hydrogen combined with these sources can serve as a means of storing this energy that would be dispensed and would not be used. In addition, hydrogen can be used as a vector to bring energy to other regions. Hydrogen produced through a renewable source such as solar photovoltaics is called green hydrogen. Brazil is a country rich in sunlight, which can be used to produce hydrogen and export to other regions. Therefore, this work seeks to survey the works that are being published in Brazil and in the world that relate to hydrogen and photovoltaic energy, showing the institutions that are developing research, the main authors and locations, among other aspects. The present research performs a search of documents in the Scopus database and uses the tool of the Bibliometrix R package to analyze the collected data. More than three thousand documents distributed in 600 journals around the world were found. There was a growth in the number of publications related to the topic around the world, and in Brazil the topic still needs to gain more space, with a more modest number of publications compared to other countries. In this way, the present work contributes to the identification of themes that are still little studied and with potential for expansion.
