Le processus électrochimique transformationnel séquestre le CO₂ 
dans l'eau de mer sous forme de carbonates et d'hydroxydes,
assurant ainsi une élimination permanente et efficace du CO2.

"ICM has developed a transformative electrolytic approach for carbon dioxide removal that exploits the ocean-air equilibrium of CO₂ and the enormous abundance of alkaline cations in seawater. The process applies renewable energy to force mineral formation via reactions between dissolved CO₂ and Mg/Ca cations via the continuous, in-situ alkalization of seawater in electrolytic flow reactors to permanently lock CO₂ as stable carbonate solids and/or as aqueous bicarbonates.

The discharge of decarbonated, brucite-enriched seawater, that is re-alkalized via the dissolution of mafic/ultramafic rocks enables the direct absorption of additional atmospheric CO₂ via rapid mass-transfer between the atmosphere and oceans. The process also produces green hydrogen: a clean fuel to power the process during intermittency, or that can be sold as a revenue garnering co-product."
