This review critically assesses membraneless and electrochemical carbon capture (e.g., EMAR, pH-swing) against conventional amine scrubbing, highlighting >90% CO₂ removal efficiency, ~60 kJ mol⁻¹ energy consumption, and ~70 USD/t cost. It also evaluates integrated reaction-swing schemes for direct syngas production. Key challenges remain in achieving industrial current densities and sorbent durability.

📄 Abstract（原文）
Electrochemical carbon capture is emerging as a promising alternative to thermally driven amine scrubbing fordecarbonising challenging industrial sectors. This review critically assesses recent advances in membraneless andother electrochemical approaches in comparison to conventional amine-based post-combustion capture.Membraneless electrochemically mediated amine regeneration (EMAR) architectures replace ion-selectivemembranes with gas-diffusion electrodes, collapsing absorption and desorption into a single electrochemical unitand eliminating ancillary equipment, such as columns and flash tanks. This redesign delivers CO₂ removalefficiencies above 90% at energy consumptions as low as ~60 kJ mol⁻¹ CO₂ and levelized capture costs near 70 USDt⁻¹, substantially below conventional EMAR and competitive with state-of-the-art thermal systems. Complementaryconcepts, including electrochemical pH-swing regeneration of amine solutions, exploit amines as buffers tomaintain favorable inorganic carbon speciation and achieve high current utilization with minimum energies near 60kJ mol⁻¹ CO₂ while preserving product purity. Integrated “reaction-swing” schemes directly electroreduce CO₂captured in tailored amine solvents to syngas, demonstrating high absorption (>84%) and improved Faradaicefficiencies, thereby circumventing separate solvent regeneration and gas compression steps. These developmentsare contextualised against the chemistry, performance and deployment of incumbent amine scrubbing and emerging electroswing systems for industrial decarbonization. The outstanding issues are to reach industrially relevant current densities and lifetimes, sorbent stability, and to incorporate electrochemical units into large-scale process flows. Convincingly, membraneless and electrochemical carbon capture technologies have a promising future in potentially replacing traditional amine systems through lower energy penalties, reducing process layouts, and allowing a flexible and electricity driven net-zero industrial process
