In the past, Sweden has mainly invested in capturing climate-damaging carbon dioxide emissions from industries. The storage is expected to take place in the North Sea with the help of other countries, such as Norway or Danish Greensand.
But now the Norwegian Geological Survey has been tasked with both investigating and identifying suitable places for storing carbon dioxide in Sweden under the seabed in the Baltic Sea. Eight potential storage locations are to be investigated more closely.
– We will start drilling on Gotland, to see what the bedrock looks like there, says Anneli Wirtén, director general of SGU.
May take 20-30 years
There are question marks about how expensive it can be, how quickly knowledge is gathered and how to handle the laws and regulations around carbon dioxide storage that exist today. According to SGU, it may take 20-30 years before we can have a Swedish warehouse in place, and believes that there is plenty of time to solve all problems.
– But we cannot map every centimeter, so of course there are always risks, says Gry Møl Mortensen, former state geologist, SGU.
Two locations are recommended – Faludden southeast of Gotland, and Arnagergrönsand in southwest Skåne – see more in the clip.
