Our technology permanently stores even-low purity CO as HCO in water using the same chemistry the ocean uses to store >90% of carbon on the surface of the planet. Combining a novel chemical reactor designed to take a wide range of CO sources, water types, and abundant mineral feedstock to drive the reaction, and a first of a kind direct sensing technology to quantify carbon molecules in water, our solution bypasses the cost, infrastructure, and limitations of the traditional CCS value chain, enabling a full-stack on-site CCS solution at unrivaled cost.
