Lon­gye­ar­by­en CO2 neu­tral?

Will Lon­gye­ar­by­en be Norway’s first CO₂ sett­le­ment? This is the visi­on of a group of sci­en­tists within UNIS (Uni­ver­si­ty in Lon­gye­ar­by­en). The geo­lo­gy around Lon­gye­ar­by­en seems sui­ta­ble for long-term sto­rage of lar­ge amounts of CO2 (CCS, car­bon cap­tu­re and sto­rage): porous sand­sto­nes are able to host lar­ge volu­mes of vola­ti­les (liquids, gas), and over­ly­ing lay­ers of fine-grai­ned sedi­ments seal this natu­ral sto­rage off to pre­vent vola­ti­les from esca­ping into the atmo­sphe­re. First tests with water ins­tead of gas went well.

The next step should be to press a lar­ger volu­me of CO2 into the ground in Advent­da­len, whe­re the test sited is situa­ted, to test the sui­ta­bi­li­ty of the sedi­ments under more rea­li­stic con­di­ti­ons. The­re are three opti­ons: sepa­ra­ting CO₂2
