Corrigendum to “Carbon capture technologies for climate change mitigation: a bibliometric analysis of the scientific discourse during 1998–2018” [Energy Reports 6 (2020) 1200-1212]

The authors regret to report that there were errors in the published article. The errors appeared in abstract, results and discussion (subheadings 3.2 and 3.5) and in the conclusion. In results and discussion under subheading 3.2 (countries/region participation), the publication details of U.K. were mistakenly split into four namely, England, Scotland, Wales, and Northern Ireland with each constituent analysed as a country. This significantly affected the productivity of U.K. In results and discussion under subheading 3.5 (Participating authors), the errors were due to arrangements and abbreviations of authors names retrieved from the Web of Science. The corrections made are given below. Abstract, line 9–11 With these motivating factors, 49 countries engaged in carbon capture technologies and related research in which the United Kingdom had the most research output followed by the United States, and China. Results and discussion 3.2 Countries/regions participation, first paragraph: A total of 49 countries were involved in research related to CCT all over the world. Among these countries, only 24 countries have a minimum of 10 publications (see Fig. 4) with most publications on post-combustion capture followed by pre-combustion capture (see Table 1). Oxy-fuel combustion had the least number of publication. In terms of total number of publications (TP), the U.K. topped the table (total publications 171) followed by the U.S.A. (total publications of 146) and China (total publications 120). The research output suggested that these countries were leading the research on carbon capture and storage for greenhouse gas emissions abatement. This was not unexpected since the U.S.A. and China are the top two emitters of CO₂ worldwide (“Climate change report card: These countries are reaching targets”, 2019) and the campaign for net-zero emission has been intensified in the U.K. in recent times. Conversely, the countries with the least publications on CCT related research were Bangladesh, Colombia, the Czech Republic, Estonia, Hungary, Indonesia, Kazakhstan, Tunisia, Turkey and Vietnam with only one publication each. In terms of total number of citations (TC), the U.S.A. had the highest citations. The top ten countries in order of citation were the U.S.A. (4416 citations) > U.K. (3607 citations) > Germany (2505 citations) > Netherlands (1971 citations) > Norway (1911 citations) > Australia (1888 citations) > China (1876 citations) > France (1795 citations) > Canada (1367 citations) > Spain (1161 citations). Continentally, Europe was the most active continent (53.86% of the total publications) and the second highest percentage came from Asia (20.68%), while Africa and South America were the least active continents (0.68% publications) (see Fig. 5). 3.5 Participating Authors 3.5.1 Co-authorship of authors, first paragraph An author's number of publications and citations are an indication of experts in a given field as well as the visibility of their research output. Among the authors retrieved, Paul Feron affiliated with CSIRO was the most published author (33 publications) followed by Meihong Wang affiliated with the University of Sheffield (28 publications), Paitoon Tontiwachwuthikul affiliated with the University of Regina (21 publications), Eric Favre affiliated with University of Lorraine (20 publications), Raphael Idem affiliated with University of Regina (20 publications) and Mathieu Lucquiaud affiliated with the University of Edinburgh (20 publications) (see Fig. 9). Interestingly, Jeffrey R. Long affiliated with the University of California, Berkeley and with only 4 publications was the most cited author (1151 citations) followed by Meihong Wang (1096 citations), Praveen Linga affiliated with the National University of Singapore (936 citations), Adekola Lawal affiliated with the Process System Enterprise (907 citations), Zoey R. Herm affiliated with the University of California, Berkeley (840 citations) and Rajamani Krishna affiliated with the University of Amsterdam (840 citations). It is worth noting that the authors Richard Baker, Haiqing Lin, Tim C. Merkel and Xiaotong Wei affiliated with Membrane Technology and Research (MTR), Inc. who had only one topical publication received 680 citations each. Conclusions and future outlook In this study, we conducted a bibliometric analysis of publications on CCT related research in the past 20 years (1998–2018) in order to show the status and trends in the application of the three main technologies, namely pre-combustion capture, post-combustion capture and oxy-fuel combustion. The findings from this work include the following: • A total of 1020 publications including articles and proceedings papers with the keywords “post-combustion”, “pre-combustion” and “oxy-fuel combustion” were retrieved from WoS database for the period 1998 to 2018. • 49 countries actively participated in CCT related research where the United Kingdom was the most productive country followed by the United States, and China based on criteria for number of publications and citations. • In terms of continents, Europe had the greatest productivity, followed by Asia. The least productive continents were South America and Africa. • CSIRO was the most active institution (based on number of publications) while SINTEF was the most cited institution. • A total of 202 journals participated in the publications of the articles and proceedings papers considered in this study. Among these journals, International Journal of Greenhouse Gas Control has the greatest productivity in terms of both number of publication and citations. The high productivity by International Journal of Greenhouse Gas Control was ascribed to its more specialised aim of publishing work relating to greenhouse gas emissions and climate change mitigation via carbon dioxide capture, transport and storage as compared to other journals that are majorly multidisciplinary. • Paul Feron was the most productive author in terms of publication, followed by Meihong Wang. In terms of citation number, Jeffrey R. Long was the most influential author followed by Meihong Wang, and Praveen Linga. • Post-combustion capture was the most covered CCT with over 80.9% of the 1020 publications retrieved, whilst oxy-fuel combustion was the least covered with 3.4% of the total publications.
