Comparative Analysis of Amine, Lime, and Molten Carbonate Electrolytic CO₂ Carbon Capture

Conventional industrial decarbonization uses energy-intensive CO 2 concentration methods such as lime or amine methods. In contrast, the electrochemical C2CNT (CO 2 to Carbon Nanomaterial Technology) directly converts CO 2 into graphene nanocarbon materials (e.g., carbon nanotubes) using molten carbonate electrolytes. This process selectively dissolves CO 2 , integrating carbon capture, concentration, and conversion in one step, while amine and lime methods require additional separate technologies for sequestration or conversion. C2CNT offers a more efficient, scalable alternative for decarbonization and carbon utilization.
