I am joining this discussion late, so I hope I am not covering ground already discussed.
Some years back a graduate student and I looked at a conceptual scheme to grow algae and sink them into the deep ocean, using increased salinity from evaporation as the “pump”. We found that the rate limiting step was not sunlight or evaporation, but rather the transport of carbon dioxide from the atmosphere into the ocean. This was, as I recall, 10 times slower than the potential rate of growth of the algae. We came to understand why agitation and CO2 addition are included in some commercial algal farms.
