The economics of direct air carbon capture and storage
by Eric Williams, Global CCS Institute, 26 pp.
This paper explores the economics of DACCS. The intent is a thought experiment to show how DACCS deployment (based on different cost assumptions) might affect the global energy system through 2065 while maintaining a net-zero CO2 pathway consistent with a 1.5°C global average temperature increase. The analysis relies on the economic model described in the methodology, in which the actors within the energy system are free to pursue least-cost options in meeting the net-zero CO2 pathway.
