Brief description

Ocean Alkalinity Enhancement is a promising negative emissions technology with high CO2 capture potential, put forward to meet the 2015 Paris Agreement targets. However, most current knowledge relies on numerical models. This dataset present the first laboratory experiments focusing on quick and hydrated lime dissolution in natural seawater, for Ocean Alkalinity Enhancement purposes. The total alkalinity and dissolved inorganic carbon concentration were collected after various alkalinity increases, using different alkaline minerals. The total alkalinity was obtained by potentiometric titration, and the dissolved inorganic carbon concentration was measured with an automated infra-red inorganic carbon analyser, coupled to a LICOR infra-red detector.

Lineage

Statement: The dissolution of alkaline minerals took place in a 2L beaker, before being transferred to a 2L Schott bottle. The incubation bottles were kept in the dark, with a stir bar stirring at about 200 rpm. The seawater was sampled using a peristaltic pump, connected to a 0.45um filter. The samples were poisoned with mercuric chloride and stored in the fridge until analysis. The total alkalinity samples were measured in duplicates, and the dissolved inorganic samples in triplicates. For further details, please consult the research paper.
