Methodologies for CO_2 storage capacity estimation: review and evaluation of CO_2 storage atlases

摘要

To effectively mitigate the negative impact of anthro-pogenic CO_2 emissions on the climate, carbon capture and storage (CCS) will need to play a key role. However, to stay below a global average temperature increase of 2°, the volumes of CO_2 to be stored are large. Under the IEA BLUE Map scenario (2009), global deployment of CCS is projected to capture and store yearly over 10 gigatonnes (Gt) CO_2 in 2050, with a cumulative storage of around 145 Gt from 2010 to 2050.
