TotalEnergies in Denmark
COPENHAGEN, 19 October 2026 – TotalEnergies Denmark has concluded offshore geophysical, geotechnical and environmental surveys at the Dagny and Inez CO₂ storage sites in the Danish North Sea. Over the past two months, the survey vessel MV Ocean Observer has carried out extensive offshore investigations across the two sites, collecting data on seabed and subsurface conditions.
The campaign marks an important step in assessing and maturing Dagny and Inez for future CO₂ storage and provides essential data for the continued development of the projects. The two sites are expected to become among the largest CO₂ storage facilities in Denmark, with a combined potential storage capacity of 335 million tonnes of CO₂ over its lifetime.
The surveys were carried out in close coordination with relevant authorities and the fishing industry, with careful consideration for the marine environment and safety throughout the campaign.
“Developing safe and scalable CO₂ storage requires a detailed understanding of the geology and environmental conditions at each site. The data collected during this campaign gives us important data to further assess Dagny and Inez and plan the infrastructure needed for potential future CO₂ storage,” said Martin Rune Pedersen, Country Chair of TotalEnergies Denmark.
A key technology for industrial decarbonization
CCS is a key technology for reducing emissions from hard-to-abate industries where electrification and energy efficiency alone are not sufficient. By capturing CO₂ from industrial activities and transporting it for safe and permanent geological storage, CCS can support industrial decarbonization and contribute to Denmark’s and Europe’s climate objectives.
“Large-scale CO₂ storage will have an important role in supporting industries with limited alternatives for reducing their emissions. By developing storage capacity in the Danish North Sea, we aim to support industrial decarbonization in Denmark and across Northern Europe while contributing to the development of a broader European CCS value chain.”
Dagny and Inez form part of the broader Bifrost CCS development, which aims to establish safe, permanent and scalable CO₂ storage beneath the Danish North Sea. The work builds on TotalEnergies’ extensive offshore and subsurface expertise in Denmark, as well as its international portfolio of CCS projects, including Northern Lights in Norway, Aramis in the Netherlands and the Northern Endurance Partnership in the United Kingdom. Together, these projects contribute to the development of large-scale CO₂ transport and storage solutions across Europe. Northern Lights was the first commercial provider of cross-border CO₂ transport and storage services in Europe and has, among others, been selected to store CO₂ captured from Danish power plants in Avedøre and Asnæs.
The offshore surveys at Dagny and Inez
The survey campaign at Dagny and Inez was carried out using the MV Ocean Observer, an 80-metre multi-role survey vessel equipped with specialized geophysical and seismic survey equipment. The campaign combined three types of offshore investigations:
- Geophysical surveys: Specialized equipment was deployed from the survey vessel and towed behind it over distances of up to 1.2 kilometers, collecting high-resolution data along predefined survey lines. The data is used to map seabed characteristics and geological layers beneath the seabed and identify potential constraints.
- Geotechnical investigations: Physical samples of soil and sediment were collected to provide information on the composition and properties of the seabed and complement the geophysical data.
- Environmental baseline studies: Seawater and seabed conditions were studied to provide baseline environmental data for the continued assessment of the sites.
About Project Bifrost
Bifrost is an EU‑designated Project of Common Interest (PCI) developing an open and scalable CO2 transport and storage network in the Danish North Sea. Delivered through two projects – Harald & Dagny, and Inez – it will connect industrial emitters in Denmark and across Northern Europe to safe, permanent offshore CO2 storage.
With operations targeted around 2030, Bifrost is expected to store up to 335 million tons of CO2 over its lifetime, forming a cornerstone of a future European carbon storage hub.
