The potential impact of the uncertainty on final estimates of net carbon removal or storage duration: negligible, low, medium, high, or very high.
Carbonates could release CO₂ if exposed to heat or acid. The risk of leakage from produced carbonates is contingent on what type of carbonate is produced, the planned treatment of the carbonates, and their resulting exposure to environmental conditions that facilitate CO₂ release.
