Comparison of different CO₂ capture technologies.

Type	Introduction	Advantage	Disadvantage	Application
CO2 captured by sorbents	The physical or chemical properties of sorbents are used to adsorb CO2	Convenient application; Rapid response; Controllable adsorption capacity	High use cost; Difficult to reuse the sorbent; Possible environmental impacts; Limited operation time	Industrial application
CO2 captured by membranes	Using the difference in permeability of different components, the purpose of separation can be achieved through a membrane	High separation accuracy; Fast separation speed; Excellent durability	High demand for equipment; Periodic replacement of membrane	Industrial application
CO2 captured by electrochemical separation	The adsorption and desorption of CO2 were realized by electrochemical means using electrolytes as a mediator	Availability of liquid products; High separation accuracy	High demand for equipment; Energy consumption is higher than other methods	Industrial; Research experiment
CO2 captured by algae cultivation	Algae capture CO2 through photosynthesis	Cost-effective; Sustainable; Applicable to a wide range of CO2 concentration; Produce value-added biomass	High footprint; Light-dependent; Operation and maintenance are complicated	Industrial; Research experiment
