Experimental Data on Seawater Slaking of Quicklime for Ocean Alkalinity Enhancement

A document detailing an experimental assessment of slaking quicklime with seawater for open-ocean alkalinity enhancement. The work, authored by Manon T. Duret, includes data on slaking efficiencies, kinetics, and secondary mineral formation, along with a transport cost model comparing material logistics. The dataset was last updated on 2026-05-29.

Use Cases

• Modeling the cost of bulk material transport for ocean alkalinity enhancement based on the described cost model.
• Assessing the technical feasibility of onboard slaking systems for marine CDR deployment based on experimental slaking data.
• Comparing the alkalinity delivery efficiency of quicklime versus hydrated lime for OAE based on the reported mass and handling properties.
• Analyzing the formation and impact of secondary minerals like brucite and gypsum in seawater slaking processes.

Strengths

• Includes specific experimental results, such as slaking efficiencies and secondary mineral weights (e.g., ~5 wt% brucite).
• Presents a quantified cost model showing a potential 4–21% reduction in transport costs per ton of CO2 removed.
• Released under a permissive CC-BY-4.0 license for reuse and modification.

Limitations

• The dataset is a 235.3 KB DOCX file, indicating a limited scope primarily focused on a specific experimental study.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for quantitative analysis.
