What it is
Since 1996 Statoil has injected into the Utsira saline formation, under the North Sea, the carbon dioxide separated from the field's natural gas, about a million tonnes a year. It was the first industrial-scale geological CO2 storage in a saline aquifer.
It was motivated by Norway's 1991 CO2 tax. CO2 injection for enhanced oil recovery is older (Texas, 1972).
What it led to
- 4D seismic monitoring of CO2 plumes
- the Snøhvit (2008) and Northern Lights (2024) projects in Norway
- the EU and IEA geological-storage framework
