COPENHAGEN, Denmark – Project Greensand has received official safety approval from DNV. The project is the first in the world to demonstrate that CO2 can be transported across national borders and stored offshore.

DNV says that the safety verification follows years of involvement in the entire value chain’s concept, design, components, underground sites and facilities. The classification society says that this safety verification covers everything from the fabrication by the individual subcontractors to the actual offshore installation.

With the safety of the pilot phase verified, Project Greensand is now able to continue working along the same lines to fulfil its ambition to store up to 1.5 million tonnes of CO2 per year in 2025/2026, and potentially up to 8 million tonnes of CO2 per year by 2030.

DNV says that its work in connection with Project Greensand has involved extensive analyses of plans, the suitability of the underground sites, and the practicability of the storage and designs, along with its physical presence during a stress test of the individual sub-elements and approval of the connection and installation of offshore systems throughout the value chain and across national borders.
