Norwegian Sea Can Hold 100 Years of Norway's CO2 Emission

OSLO (Reuters) -

The findings are most relevant for natural gas finds such as the Sleipner field in the North Sea, where the gas contains high levels of carbon dioxide.

Norway has imposed taxes on carbon emissions since 1991 as part of efforts to limit climate change.

An atlas by the Norwegian Petroleum Directorate (NPD) showed that geological formations could store 5.5 billion metric tons (6.06 billion tons) of carbon dioxide beneath the Norwegian Sea, against current annual Norwegian emissions of about 50 million metric tons.

The storage is a fraction of the 70 billion metric tons of storage space below Norway's sector of the North Sea, as estimated in a 2011 NPD study. The NPD is still mapping storage sites in the Arctic Barents Sea.

"The Atlas shows that there are several suitable sites" for storage, Oil and Energy Minister Ola Borten Moe said in a statement. Norway is Europe's second-largest gas supplier after Russia.

At Sleipner, operator Statoil has stripped about a million metric tons a year of carbon dioxide since 1996 - a necessary step to make natural gas of saleable quality - and re-injected the carbon deep below ground to avoid the tax.
