Denmark’s underground is rich with potential for CO2 storage. The country has an estimated capacity to store 22 billion tons, corresponding to between 500 and 1000 years of Danish emissions at the current level.

Gas Storage Denmark is tapping into this potential by developing the country’s first onshore storage facility in the town of Stenlille. As the first of its kind, this endeavour requires comprehensive investigations and the development of new technologies to guarantee both safety and effectiveness.

A vital aspect is the implementation of a robust monitoring system to effectively manage and mitigate the risk of leakage. The BOMS project addresses this challenge.

BOMS is developing a monitoring solution to accurately track conditions inside and around onshore wells for CO2 injection. The research project is part of the INNO-CCUS partnership and is led by a collaboration between Gas Storage Denmark and Technical University of Denmark, Welltech, Geological Survey of Denmark and Greenland (GEUS), BlueNord, and Technion.

BOMS creates an overview of existing monitoring technologies and identifies the most important gaps between available technology and the specific data needs for onshore CO2 storage. Based on this knowledge, the project aims to enhance and recommend monitoring techniques for CO2 storage sites. This effort includes advancing sensor technologies, improving data integration methods, and optimising real-time monitoring capabilities.

A reliable and accurate monitoring solution is a vital piece of the puzzle for CO2 storage. By improving our knowledge of subsurface conditions and enhancing monitoring techniques, the BOMS project contributes to the safe operation of the Stenlille facility, which plays a key role in advancing Denmark’s Carbon Capture and Storage (CCS) initiatives. Additionally, the practical insights and recommendations from BOMS will help guide the development of monitoring solutions for future onshore storage sites.
