Carbon Capture and Storage (CCS) is a promising technology to fight climate change, and a new study from DHRTC points to scientific research as key to unlocking the Danish North Sea’s potential for Carbon Storage.

"CO2 Storage in Danish Oil and Gas Fields – a state-of-the-art study" is a comprehensive literature review combined with expert interviews. It provides a detailed overview of the current knowledge of the potential as well as the challenges of using the Danish oil and gas fields for storing of CO2.

Over the past 50 years of oil and gas activities, a vast amount of data and subsurface knowledge has been acquired for the fields. The study describes that this knowledge together with significant reservoir storage capacity after cessation of production, and existing infrastructure in terms of wells, pipelines, and platforms make a strong case for offshore CO2 storage as a potentially time and cost effective solution.

The majority of the Danish oil and gas fields are producing from chalk reservoirs, which have significant potential CO2 storage capacity but also present some complex challenges. The DHRTC study identifies key areas where scientific research and technology development will assist in unlocking the potential for CO2 storage:

  • CO2 storage capacity of Danish chalk and other oil and gas reservoirs
  • CO2 injectivity of different chalk reservoir types and storage integrity
  • Optimisation of the balance between CO2 transport options and injection
  • Remaining lifetime of the existing wells and their suitability for CO2 injection
  • Development of cost effective and reliable monitoring methods and technologies

The study, which has been compiled by Charlotte Nørgaard Larsen, Hamid Nick and María Bonto from DHRTC analyses each of the areas mentioned above and identifies gaps in the existing knowledge.
