Trends in carbon capture technologies: a bibliometric analysis

Abstract

Climate change is an ever-present issue, which has a vast variety of potential solutions, one of which being carbon capture. This paper aims to use bibliometric analysis techniques to find trends in carbon capture within the technologies of adsorption, absorption, membranes, and hybrid technologies. The Web of Science core collection database performed bibliometric searches, with the ‘Bibliometrix’ plug-in for R software, performing the bibliometric analysis. Bibliometric data spanned across 1997–2020 and the investigation found that adsorption technologies dominated this period in terms of citations and articles, with hybrid technologies being the least produced but rising in scientific productivity and citations. The Analysis found China and the United States of America to be the dominant producers of articles, with global collaboration being central to carbon capture. The ‘International Journal of Greenhouse Gas Control’ ranked as the top producer of articles however, the ‘ACS Applied Materials & Interfaces’ was the leading journal in terms of H-index.
