Abstract

Economic growth and the increase in population have caused greater generation and consumption of fossil energy, increasing CO₂ emissions into the atmosphere, directly impacting climate change and global warming. Carbon capture, utilisation, and sequestration (CCUS) are essential for reducing greenhouse gas (GHG) emissions and achieving carbon neutrality. This article aims to analyse the scientific production on CCUS in Scopus through the application of bibliometric techniques and a systematic review of the knowledge of the different techniques used, their distribution and trends. The methodological process consisted of three phases: (i) collection and processing of scientific information, (ii) bibliometric analysis using the Bibliometrix and VOSviewer software, and (iii) systematic review of the CCUS techniques used using the Preferred Reporting Items for Systematic method Reviews and Meta-Analyses (PRISMA). The results showed a growing trend of annual publications on CCUS in the last decade, highlighting improvements in the storage technique in geological formations and oil production processes. Similarly, methodological trends have been identified for industries that reduce GHG emissions. The results of this study represent a tool for researchers and decision-makers related to CCUS that allows them to know the areas investigated to date, including the different CCUS techniques and their respective benefits and limitations.
