Project Bifrost Phase 2: The Inez license

Phase 2 focuses on the Inez storage license and is intended to scale and expand CO2 storage capacity beyond Phase 1, in line with growing market demand and cross‑border CCS developments.

The scope of Phase 2 includes:

  • Appraisal and development of the Inez storage license to unlock large‑scale, long‑term CO2 storage potential
  • Evaluation of flexible CO2 transport solutions, including offshore and onshore pipeline connections and ship‑based transport, depending on market development
  • Integration with regional and cross‑border CO2 infrastructure to support emitters from Denmark, the Baltic region and Northwest Europe
  • Enabling higher storage volumes over time and strengthening Denmark’s role as a European CO2 storage hub

Phase 2 is designed to ensure Project Bifrost can accommodate increasing CO2 volumes and support Europe’s long‑term climate objectives.

Inez saline aquifer

The Inez license covers a deep saline aquifer in the Danish North Sea and represents an important contribution to the CO2 storage capacity required under Project Bifrost. The storage potential of the Inez area has been identified through preliminary geological studies and will be further assessed as the project progresses. A saline aquifer is an underground rock formation containing salty water (brine) that is unsuitable for human consumption or agriculture. At Inez, the aquifer is located deep below the seabed and is sealed by impermeable rock layers, allowing injected CO2 to be safely and permanently stored. The reservoir lies well below the minimum depth required to ensure that CO2 remains sufficiently compressed, supporting long‑term containment. Deep saline aquifers such as Inez are found far beneath the Earth’s surface and have the potential to store large volumes of CO2 securely, making them a key geological solution for large‑scale carbon capture and storage.
