Carbon removal by converting captured CO2 into dissolved bicarbonate with limestone and water, a closed engineered weathering system the company calls its own patent-pending technology. The first production unit is project HELIX in Hetlingen, Schleswig-Holstein, listed in the Isometric registry as Biogenic Carbon Capture and Storage with the status Validated and certificates expected in 2027. The company states field testing across four German sites, a larger facility OSTREA in northern Germany for 2026 and a project NAUTILUS in Switzerland, which would fall outside the CRCF. A second pathway produces the mineral ikaite and releases it into marine environments to raise ocean alkalinity; that route has no CRCF methodology, the Commission lists marine carbon dioxide removal at exploration stage. No units have been issued, so the status stays Developer-stated.
