Norway-listed Noreco has formed an alliance with Denmark’s Orsted and Nordsofonden, the Technical University of Denmark and TotalEnergies to investigate a proposal — codenamed Project Bifrost — to store carbon dioxide in the Harald field in the Danish North Sea.

TotalEnergies and Nordsofonden are already Noreco’s partners in the Danish Underground Consortium (DUC) that is responsible for the majority of gas and oil production in Danish waters.

The DUC operates the Harald gas condensate field, which is close to the operator’s most important asset, Tyra, a gas field undergoing redevelopment with the goal of restarting production in 2023.

According to Noreco, the Harald field consists of two structures, Harald East and Harald West, discovered in the first half of the 1980s, with four producing wells still in operation.

The repurposed Harald carbon capture and storage (CCS) complex is expected to provide annual storage capacity of 3 million tonnes.

Noreco said the Technical University of Denmark will be an academic partner in the alliance, delivering technical studies.

This calls for laboratory testing and simulation and socioeconomic studies exploring sector integration, including the assessment of the positive impacts on innovation, export opportunities and job creation of a new CCS industry in Denmark.

Orsted owns the pipeline infrastructure connecting DUC’s fields and installations in the North Sea to shore. It will conduct technical studies to repurpose the infrastructure to transport CO2.

Project Bifrost will be matured towards a final investment decision if its application for funding and the following development and demonstration programme prove successful, Noreco said.

The alliance previously applied for government funding under the Energy Technology Development & Demonstration Program that is administered by the Danish Energy Agency.

The scope of the current application includes a study on the potential of using additional underground reservoirs controlled by the DUC for CO2 storage, as and when they become available.
