Alternative ways for CO2 capturing?

If ocean can absorb CO2 in that way, then instead of the current research on much more costly CO2 capturing and storing underground technologies, perhaps studies should be undertaken to explore how make the CO2 (from power generations or large concentrations of some other CO2 producing processes) pass through water to be captured and and stored in water to be either put into the ocean or used in irrigation.

Would that be a feasible project or idea to deal with CO2 emissions?
