Amine-based capture of CO2 for utilization and storage5 answersAmine-based capture of CO2 is an important technology for both utilization and storage purposes. It is considered an effective CO2 fixation technology in the context of global warming and climate change. The development of carbon dioxide capture and utilization (CCU) technology, which reuses captured CO2, has been prioritized to accelerate the deployment of "CCUS". A new strategy has been developed to improve the CO2 capture performance of solid amine sorbents by introducing CO2-neutral surfactants, resulting in enhanced CO2 dynamic capacity and total capacity. Non-biological CO2 mineralization has also been demonstrated using amine-mediated chemistry, leading to the preparation of well-defined metal carbonate crystals. However, the potential degradation of amines is a significant issue that hinders the large-scale deployment of amine-based capture technologies. Overall, amine-based capture of CO2 offers potential solutions for both utilization and storage, but further research is needed to address degradation issues and improve performance.
