Research and consulting experience

Since 2008, NGI has amassed extensive experience in research and consulting on CO2 storage. This includes more than 20 research projects funded by CLIMIT (Gassnova and RCN), FME, and ERA-NET ACT, within NGI's focus areas of seal integrity, risk evaluation, and monitoring.

NGI has also been involved in reviewing CO2 storage permit applications within the depleted gas field in the Netherlands and is providing consulting services to the Northern Lights JV.

Recent projects are listed below with links to where more information can be found.

Experience with CO2 storage sites and pilots

NGI has gained experience relating to active sites currently injecting CO2 on large-scale, storage sites planned for large scale injection and CO2 storage pilots for testing and demonstration around the world. Below is a list of projects where NGI have been involved.

  • Norway: Active storage sites Sleipner and Snøhvit, Northern Lights JV storage candidates Smeaheia and Aurora in Hordaplatform area, and the CO2 pilots Longyearbyen and Svelvik.
  • Netherlands: Porthos - Review of CO2 storage license applications
  • Algeria: In Salah CO2 storage site
  • US: Decatur CO2 storage site
