Abstract Carbon capture, utilization and storage (CCUS) technologies play an essential role in achieving Net Zero Emissions targets. Considering the lack of timely reviews on recent advancements promising CCUS technologies, it is crucial to provide a prompt review advances understand current research gaps pertained its industrial application. To that end, this first summarized developmental history large-scale demonstrations. Then, based visually bibliometric analysis, carbon capture remains...
