19. Interesting idea...

How does the 242 kJ/mol to extract carbon dioxide from seawater compare to the air technique? (The article in the OP gives us no good way to tell...)

Also, I think that while there's much more carbon in seawater than air per unit volume, there's actually more CO2 in air when you look on a ppm basis. I'm not sure which metric would more relevant here...
