Altera Infrastructure has appointed AGR to conduct an independent third-party storage evaluation of the Havstjerne CO₂ storage license offshore Norway.

In late March, the Norwegian Ministry of Energy awarded Altera Infrastructure and its partner Wintershall Dea a Carbon Capture and Storage (CCS) license to develop the Havstjerne CO₂ storage site in the North Sea.

The CO₂ storage site, with an annual capacity estimated at 7 million tonnes per annum (Mtpa), is located 100 kilometers southwest of Egersund, Norway.

AGR’s scope of work includes CO₂ storage site screening and characterization for potential CO₂ storage, independent third-party storage evaluations, and geological assessment and mitigation of the risks associated with CO₂ leakage. AGR has not disclosed the value of its contract.

The Havstjerne reservoir is planned to be in operation in 2027. The project envisions injecting CO₂ transported by shuttle tankers and pipeline from multiple carbon capture hubs across mainland Europe.

“This project represents a step forward in the global battle against climate change, and we are proud to be involved in such a meaningful project. AGR has previously been involved in two other North Sea flagship projects—the Northern Lights and Greensand in Denmark—and we will utilise this know-how to support Altera Infrastructure and Wintershall Dea on Havstjerne,” adds Erik Lorange, Vice President Reservoir Management, at AGR.

AGR has also supported Norwegian Offshore Directorate in compiling the CO₂ Atlas of Norwegian Continental Shelf which documents potential carbon storage sites including storage capacity volumes and site characterizations.

AGR is part of Oslo-listed energy and marine consultancy group ABL Group ASA.
