Inside our engineered system, CO₂, water, and alkaline minerals react under precisely controlled temperature conditions to form ikaite, a crystalline compound optimized for stability and dissolution behavior. When introduced into suitable marine environments, ikaite gradually dissolves, raising alkalinity and enabling the ocean to capture and store atmospheric CO₂ as bicarbonate. This controlled, verifiable process leverages proven marine geochemistry to deliver large-scale, permanent carbon removal.

The science behind Planeteers’ HCM technology is designed for permanence, traceability, and ocean safety. Each step – from ikaite formation to its gradual dissolution – is validated under controlled temperature and saturation conditions that maintain marine balance while enhancing natural alkalinity.

Comprehensive monitoring of alkalinity, pH, and dissolved inorganic carbon ensures transparent, quantifiable tracking of CO₂ conversion and long-term storage stability. All processes follow the Isometric Ocean Alkalinity Enhancement protocol, providing verifiable, science-based confidence in every tonne of carbon removed.
