Progress in carbon dioxide capture materials for deep decarbonization

Summary

To prevent runaway climate change, the goal of carbon neutrality calls for an aggressive use of decarbonization technologies such as carbon capture from flue gas and direct air capture (DAC) of carbon dioxide to meet the goals of the Paris Agreement. Both of these techniques rely on carbon dioxide (CO₂) sorbents or diffusion membranes, which can take many forms. To inform about various forms of CO₂ capture processes, here, we have reviewed a collection of the latest developments with liquid sorbents, solid sorbents, metal-organic frameworks (MOFs), and diffusion membranes. Their potential capture capacities and reaction kinetics, stability, and reusability are presented and compared. In addition, we discussed potential alternatives to the conventional method of regenerating the sorbent capacity. Such a comprehensive summary of progress in this field can facilitate essential research, describe enabling technology innovations, and promote industrial implementations of carbon capture technologies for deep decarbonization.
