LONDON, Apr. 25 -- StatoilHydro has begun to inject carbon dioxide from the Snohvit well stream into the Tubasen sandstone formation beneath the field to reduce greenhouse gas emissions from the liquefaction plant.
The CO2 will not escape because of a shale cap on top of the sandstone. The company said that it would improve its carbon storage skills for other areas with the carbon capture plant that is expected to store 700,000 tonnes/year of CO2 at full capacity. This is the second largest carbon capture project in Norway.
"The natural gas, which is piped from the Snohvit field to Melkoya outside Hammerfest contains 5-8% CO2. At the onshore plant on Melkoya, CO2 is separated from the natural gas and piped back to a formation at the edge of the Snohvit reservoir, where it is stored 2,600 m beneath the seabed," StatoilHydro said.
One million tonnes/year of CO2 are already stored beneath the seabed in Sleipner field. StatoilHydro is also involved in carbon storage on the gas and condensate field In Salah in Algeria in cooperation with BP PLC and Sonatrach.
