StatoilHydro has stored 10 million tonnes of carbon dioxide underground at Sleipner in the North Sea. The company removes 2,800 tonnes of CO2 from natural gas produced on the Sleipner West field in the North Sea every day and injects and stores it in the Utsira formation.
This sandstone formation extends over a large area in the Norwegian sector of the North Sea. The facility has been online since the autumn of 1996, recording a very high regularity.
Research and monitoring of the carbon injection into the Utsira formation show that the greenhouse gas is retained in the formation.The Sleipner organization is exploring the possibilities of offering other petroleum discoveries in the area the opportunity to process gas, remove CO2 from the gas and store it in the Utsira formation. The possibility of receiving carbon dioxide from land for injection into the Utsira formation is also being considered.
A decision by the EU Parliament as to whether, and on what conditions, carbon storage may be permitted is scheduled for this year.
