| Summary: | This bibliometric analysis is a following part that aims to expand the information from our previous study. Direct Air Capture (DAC) technologies are not progressing as fast as expected and time is limited. Research and shared knowledge can accelerate the implementation of DAC and Carbon Capture Utilisation and Storage (CCUS) solutions. Numerous authors publish their findings on different platforms and journals. Thus, this bibliometric analysis is using Web of Science as data base. During this study, two cases of study were performed: one merges concepts such as ``carbon capture,'' CO2 capture and DAC, and a second one only focused on removing the CO2 from the atmosphere; being the latter at the principal topic of this analysis. CCUS and DAC + S share the same approach to capture CO2, yet the conditions are quite different. Many articles related to DAC were overshadowed by words such as ``CO2 capture'' and ``carbon capture.'' However, the results showed that in 1999, Professor Lackner was the first scientist who suggested the implement of DAC technologies. After him, a great number of authors followed up and researched on the topic. Based on the outcomes of this study, United States, Europe and China are leading the research. The United States holds the major number of publications and has strong links with the rest of the countries, which implicates that authors from other nations collaborate with the North American country. Yet, it is necessary to increase its social acceptance to accelerate the deployment of these technologies.
