In order for Sweden to reach the climate target by 2045, emissions must be reduced sharply. But the government also wants to invest in the capture, separation and storage of carbon dioxide from burning biofuels, so-called bio-CCS.
Sandstone in the bedrock
Sweden’s Geological Survey (SGU) has been tasked with investigating suitable locations for storing carbon dioxide in Swedish bedrock. In southern Gotland, they will drill down to 800 meters on land, in order to also get a picture of what the bedrock looks like under the sea.
– We will investigate the conditions in the bedrock and whether there might be an opportunity to store carbon dioxide in Sweden, says Lena Yotis, project manager at SGU.
Leakage possible risk
A possible risk that is highlighted when it comes to large-scale storage of carbon dioxide under the seabed is that it will leak out and, for example, contribute to acidification.
– We will look at the conditions for the carbon dioxide to remain in the reservoir and not be contained, says Yotis.
The project is expected to last until 2026.
