DigiMon – Digital Monitoring of CO₂ Storage projects

Affordable and flexible monitoring systems for CO2 storage are important for successful deployment of CCS value chains.

A key component of any CCS project is measurement, monitoring and verification (MMV), which must demonstrate that projects are planned and executed in a societally acceptable manner and that adequate technologies are implemented to ensure safety and security.

Multiple technologies at lower cost

A key scientific challenge is to deploy a cost-effective optimal combination of technologies that can collectively improve the probability of successfully verifying containment or detecting breaches in CO2 barriers.  The overall objective of the DigiMon project was to “accelerate the implementation of CCS by developing and demonstrating an affordable, flexible, societally embedded and smart Digital Monitoring early-warning system”, for monitoring any CO2 storage reservoir and subsurface barrier system. The project included laboratory experimental studies and collection of field test data along with modelling and optimization. A strong focus on interdisciplinarity, between technical and social sciences, characterized the research.

New knowledge with the help of DigiMon 

DigiMon has contributed to improving individual system components and development of workflows for processing and interpretation of monitoring data, particularly a framework for inversion of multiple geophysical data. In addition, it has developed unique methodology for evaluating CCS technologies from the point of view of societal acceptability and benefit. 

DigiMon was funded by ACT (Accelerating CCS Technologies) and hosted by NORCE. Other Norwegian partners included NTNU, MonViro, Equinor and Repsol. International partners counted CRES (Greece), Geotomographie and UFZ (Germany), Lawrence Livermore (US), Sedona (Romania), Silixa and Universities of Bristol and Oxford (UK) and TNO (The Netherlands). The project started in 2021 and was completed by end of 2022.

Monitoring of CO2 storage.

Sub-objectives for the DigiMon project included:

  • Provide a system for monitoring the CO2 plume and identify and provide early-warning of actual or potential breaches in the subsurface barriers.
  • Provide a flexible and interchangeable system with respect to the environment (offshore or onshore) and new system components provided by market-driven technology development.
  • Provide a societally relevant monitoring system that addresses the views and worries of various stakeholder groups and citizens.
  • Provide knowledge communication and dissemination to the public and policy makers.
