DNV Confirms Technical Viability of CO₂ Transport and Injection System for Norwegian Offshore Project
Classification society DNV has issued a Statement of Feasibility for Aker BP and Höegh Evi’s innovative offshore carbon capture and storage (CCS) concept, designed to transport and permanently store liquefied CO₂ at the Atlas field in the Norwegian North Sea.
The proposed system leverages Höegh Evi’s specialized shuttle carrier vessels to transport liquefied CO₂ from onshore processing facilities to designated subsea injection sites. Upon arrival, the CO₂ is injected directly into depleted or suitable geological formations for long-term storage, eliminating the need for extensive onshore infrastructure.
This approach aligns with Norway’s ambitious carbon neutrality targets and could serve as a scalable model for offshore CCS deployment in mature oil and gas fields. DNV’s assessment underscores the technical and operational feasibility of the concept, marking a key milestone in advancing offshore carbon storage solutions.
Key Technical Considerations
- CO₂ Transport: Shuttle carriers equipped with cryogenic storage tanks ensure efficient and safe transfer of liquefied CO₂ from shore to injection sites.
- Subsea Injection: Direct injection into wellbores eliminates surface infrastructure risks and optimizes storage capacity.
- Regulatory Alignment: The concept adheres to Norwegian and international CCS standards, ensuring compliance with environmental and safety protocols.
- Scalability: The modular design allows for potential expansion, accommodating future CO₂ capture projects in the region.
The validation by DNV—recognized for its expertise in offshore energy and decarbonization—reinforces the project’s potential to contribute meaningfully to Norway’s low-carbon energy transition while maintaining operational integrity in a challenging marine environment.
