According to the majority of scenario projections to a net-zero economy, the role of Carbon Capture, Utilisation and Storage is significant and diverse. Of all the different CO2 capture technologies, chemical absorption has the highest Technology Readiness Level and has been the main field of research. Nevertheless, low-temperature CO2 capture technologies have the potential to offer several unique advantages, notably to provide higher CO2 recovery and purity than other separation technologies. This article covers an overview of different CO2 capture techniques that have been developed with a focus on selected low-temperature technologies. Their respective Technology Readiness Levels are also considered, together with associated costs, environmental impact and scaling potential of the different technologies. Considerations regarding the complete Carbon Capture, Utilisation and Storage value chain, as well as future challenges and disadvantages that prevent widespread adoption are also presented. We conclude with discussion of potential applications as well as synergies considering the characteristics of low-temperature CO2 capture technologies.
