New independent 3rd party site endorsement paves the way for future expansion

New independent 3rd party site endorsement paves the way for future expansion.

DNV has now issued a certificate for site endorsement for the entire Nini Main and East area – a key step forward for Greensand and the long-term development of offshore CO₂ storage in the INEOS operated area of the Danish North Sea in accordance with EU and Danish legislation.

“This endorsement from DNV is an important milestone. It underlines that we are not only on track for large-scale commercial storage from mid-2026 – we are also building the foundation for long-term growth. It opens the door to expand the storage capacity and support the European Industry with the storage needed,” says Mads Gade, CEO INEOS Energy Europe.

The independent site endorsement confirms that the Greensand site is technically suitable for safe and permanent storage of CO₂ and the estimated capacity.

The required geological and operational documentation is in place to support Authority permitting as well as stakeholder decisions hereunder for CO₂ emitters for storage site suitability.

The certification extends across the reservoir, geology, well engineering concept and injection facility aspects and forms part of the DNV unique industry vetted certification framework.

“The site endorsement of Nini Main and East was issued following a well defined scope with detailed independent 3rd party verifications in accordance with our Certification scheme of sites and projects for geological storage of CO2 DNV-SE-0473. The certificate confirms that the Greensand site is qualified, compliant with EU and Danish Law, international standards and key requirements for safe geological storage of CO₂,” says Mick Cramer Jakobsen, Managing Director for DNV Denmark and Vice President Energy Systems Region Norther Europe.

Next steps include intensified dialogue with Danish authorities to secure the necessary permits and approvals for the future expansion of Greensand.
