TLDR
Amine-based post-combustion CO2 capture technology has a great potential to control CO2 emissions but is expensive because a huge amount of thermal energy is required for solvent regeneration due to solvent depletion as mentioned in this paper.Abstract:

Catalytic activity of facilely synthesized mesoporous HZSM-5 catalysts for optimizing the CO2 desorption rate from CO2-rich amine solutions
Umair H. Bhatti,Abdul Karim Shah,Amjad Hussain,Hassnain Abbas Khan,Chan Young Park,Sung Chan Nam,Il Hyun Baek +6 more
TL;DR: In this paper, a series of mesoporous HZSM-5 catalysts were synthesized through facile alkaline desilication and surfactant-induced reassembly of dissolved species originating from the parent HZ SM-5 crystals, and evaluated their performance to optimize the CO2 desorption rate from benchmark 30wt% monoethanolamine (MEA) solution under mild temperature condition.

Carbon dioxide postcombustion capture: a novel screening study of the carbon dioxide absorption performance of 76 amines
Graeme Puxty,Robert Rowland,Andrew Allport,Qi Yang,Mark Bown,Robert C. Burns,Marcel Maeder,Moetaz I. Attalla +7 more
TL;DR: Most of the outstanding performers in terms of capacity also showed initial absorption rates comparable to the industry standard monoethanolamine (MEA), which indicates, in both absorption capacity and kinetics, that they are promising candidates for further investigation.
