The purpose of this study is to investigate articles published in the Scopus database dealing with multigeneration energy systems using biogas as fuel. This investigation was conducted by means of a bibliometric review. The free VOSviewer software was chosen to process this data, in which bibliometric networks were set up such as citations, co-authors, year of publication and keywords that listed relevant information from the articles. Based on these bibliometric networks, graphs and maps were added to this work, making it possible to infer and evaluate the results of the research field. The bibliometric review indicated that over the last two decades there has been a vertiginous growth in article production, with the last decade alone accounting for approximately 37% of all publications, even more than in the previous decade, which shows the growing interest in the subject. China leads the ranking of publications with approximately 22% of research on the subject and the top 4 countries, China, Italy, Iran and Germany, together account for approximately 60% of research. It can be concluded that these systems are increasingly studied and regarded as a promising model for energy sustainability.
