Havstjerne Carbon Storage Project

Havstjerne CO2 storage

The Havstjerne project (EXL 006 Havstjerne) is a pioneering carbon storage development located in the North Sea on the Norwegian Continental Shelf, 135 kilometers southwest of the city of Stavanger on the Norwegian mainland.

Positioned as one of the first to-market CCS projects in Europe, Havstjerne is strategically designed to offer permanent and scalable offshore CO2 storage.

The partnerships intend to develop a system for transporting CO2 by ship to the Havstjerne license offering storage to emitters from around Europe.

Project Highlights

Awarded by the Norwegian Ministry of Energy (2023) and supported by the EU Innovation Fund.
This project has received official recognition and support, underscoring its strategic importance in Europe’s energy transition.

World-Class CO₂ Storage Site

  • Located 2,250–3,300 meters below sea level
  • Features a proven and tested reservoir with excellent storage properties
  • Secured by a robust geological seal system composed of thick, impermeable claystone and Cretaceous formations

Strong Industry Collaboration

  • Harbour Energy as storage operator
  • Stella Maris CCS (a Yinson Production company) as storage license partner and supplier of the injection facilities

Supporting Data & Validation

Advanced Subsurface Characterization

  • Recent 3D seismic (2022–2023) provide detailed insights into the storage reservoir and form the basis for CO₂ monitoring during the injection phase

Comprehensive Well Data

  • Havstjerne Exploration Well (2025)
  • Wintershall’s (now Harbour) exploration well from 2015
  • Off-set data from the nearby Yme oilfield

Proven Injection Capability

  • Successful injection test conducted in the Havstjerne well
  • Additional validation from injection activities in the Yme field
