本レビューは、メンブレンレス電化学生成アミン再生（EMAR）など電気化学的炭素回収技術の最近の進展を、従来のアミン系システムと比較して評価する。EMARはイオン選択膜をガス拡散電極に置き換え、吸収と脱着を単一の電気化学ユニットに統合し、90%以上のCO2除去効率と約60 kJ mol⁻¹の低エネルギー消費を実現する。また、pHスイングや反応スイング方式など補完的な手法も検討し、産業脱炭素化への可能性を示す。
English
This review critically assesses recent advances in membraneless and electrochemical carbon capture, comparing them to conventional amine scrubbing. Membraneless electrochemically mediated amine regeneration (EMAR) achieves >90% CO2 removal at ~60 kJ mol⁻¹ CO2 with capture costs near 70 USD/t, offering a lower-energy alternative. Complementary approaches like electrochemical pH-swing and reaction-swing are also evaluated, highlighting potential for industrial decarbonization.

📄 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
