The scientific community is currently examining potential approaches in order to reduce the anthropical contributions to global warming. One approach is carbon capture and its storage, i.e., capturing CO 2 at its source and storing it indefinitely to avoid its release into the atmosphere. Conversion of CO 2 by microalgae or cyanobacteria is a sequestration option. Here, the application of an air‐lift reactor to flue gas treatment using cyanobacteria for the absorption of CO 2 was investigated, with the simultaneous abatement of NO x . A Spirulina platensis culture was fed with CO 2 and NO x , simulating a flue gas. The preliminary test yielded positive indications on the process feasibility, both in terms of cell productivity (86.8 mg L –1 d –1 ) and CO 2 abatement (229 mg d –1 ). Opportune dosages of flue gas used in fed‐batch test achieved a high abatement of CO 2 (407 mg d –1 ), 90.0 % removal of NO x , and a biomass production of 188.7 mg L –1 d –1 .
