CO₂-storage in Adventdalen

The idea to run Spitsbergen “carbon-free” is based on CCS: capturing and consequent storage of carbon dioxide in sandstone layers in the ground. After three scientific drillings had to be aborted due to technical difficulties, a fourth one has successfully reached promising sandstone layers at a depth of up to 870 metres. Less than 1000 metres that had been hoped for, but enough in case further testing shows the layers to be capable of long-term storage of CO₂-emissions from, for example, Longyearbyen’s coal power plant.

Techniques thus developed by UNIS (the university in Longyearben) might in the future be used elsewhere in the world.
