DNV and Ørsted Achieve Milestone in Carbon Capture and Storage Project Bifrost with Feasibility Study Approval for CO2 Transportation via Repurposed Pipeline

(IN BRIEF) DNV and Ørsted have achieved a major milestone in the development of Project Bifrost, a CCS project aimed at CO₂ underground storage in the Danish North Sea. DNV has granted a Statement of Feasibility (SoF) for repurposing Ørsted’s 24″ hydrocarbon pipeline for CO₂ transportation. The feasibility study confirmed the pipeline’s suitability for re-qualification to transport CO₂. This milestone underscores Ørsted’s efforts to reduce carbon emissions and contribute to a sustainable future. The companies also co-authored a paper on the pipeline’s conversion, to be presented at the 2025 Pipeline Technology Conference.

(PRESS RELEASE) BÆRUM, 7-May-2025 — /EuropaWire/ — DNV and Ørsted have reached a major milestone in the development of Project Bifrost, a carbon capture and storage (CCS) initiative aimed at underground CO₂ storage in the Danish North Sea. DNV has awarded Ørsted a Statement of Feasibility (SoF) for repurposing Ørsted’s existing hydrocarbon pipeline for CO₂ transportation.

The feasibility study, conducted by DNV, assessed the 24” diameter pipeline running approximately 300 kilometers between the South Arne/Harald offshore platforms and the Nybro gas treatment plant in Western Jutland. The study concluded that the pipeline is suitable for re-qualification for CO₂ transport based on DNV’s recommended practice DNV-RP-F104 for design and operation of carbon dioxide pipelines.

Mick Cramer Jakobsen, Vice President and Head of Customer Relations and Sales for Region Northern Europe, Energy Systems at DNV, stated, “The successful feasibility statement of Ørsted’s pipeline for CO₂ transport represents a significant step in our commitment to advancing CCS technologies. This project not only demonstrates the technical feasibility of repurposing existing infrastructure but also highlights the critical role of collaboration in achieving our climate objectives.”

Jesper Kok Frost, Project Manager at Ørsted’s Infrastructure Assets, expressed, “We are pleased with the outcome of the feasibility study and look forward to continuing our work with DNV to ensure the safe and efficient transport of CO₂. This project plays a pivotal role in Ørsted’s strategy to reduce carbon emissions and contribute to a more sustainable future.”

The preparatory work for the pipeline’s re-qualification has also led to a collaborative innovation, resulting in a paper co-authored by DNV and Ørsted, titled “Conversion of an Offshore Natural Gas Pipeline to CO₂ Service, a Practical Approach to Avoiding Running Ductile Fracture.” The paper will be presented by Jesper Stavnsgaard, Senior Pipeline Engineer at DNV, at the 20th Pipeline Technology Conference in Berlin from May 5-8, 2025. The findings could offer valuable insights for other operators aiming to repurpose infrastructure for the energy transition.

About Project Bifrost

• Project Bifrost is a collaboration between the Danish Underground Consortium partners TotalEnergies (lead-operator of DUC), Noreco and the state-owned Nordsøfonden who hold the licenses for the subject oil and gas fields in the Danish North Sea, Ørsted who owns the pipelines for the potential transport of CO2 offshore and Denmark’s Technical University.
• Project Bifrost performs the groundwork necessary for transporting and storing CO2 underground offshore in the Harald field: From the CO2 being captured on land to the transportation offshore via specialized shipping or existing pipelines – and finally injected into the empty gas reservoirs at the Harald field.
