Higher efficiency of CO2 injection into seawater by a venturi than a conventional diffuser system

► In this study, a venturi was used to inject and dissolve CO2 in the seawater in the open ponds. ► The transfer efficiency of CO2 were compared with the air diffuser for injecting CO2 into pond water. ► The absorption of CO2 were compared with the air diffuser for injecting CO2 into pond water.
