Ionic liquids are tunable, low volatile and energy efficient, which make them promising materials for electrochemical CO₂ capture as an alternative to the conventional carbon capture. The application of this process relies on the specific physicochemical properties of ionic liquid (IL)s: high solubility to CO2 and electrochemical stability, which allows ionic liquid (IL)s to reversibly absorb and release carbon dioxide as a result of changing potential under the specified conditions. Thermal energy doubts are reduced compared to traditional amine-based methods, leading to higher compatibility with renewable electricity sources. This work carries out a comprehensive analysis of reactor configurations, mass transport dynamics, ionic liquid (IL) regeneration strategies and cost-effectiveness of this process for industrial deployment. The paper describes how special attention is given to the optimization of electrode materials, cell geometry, and process integration for scalable operations. Novel approach is technoeconomically modelled and lifecycle analysis is addressed to highlight advantages and bottlenecks when scaling is needed. The study shows a path forward for turning CO₂ capture from an energy-intensive, energy-input-requiring process to one that becomes part of the solution to the global decarbonization problem.
