This report examines 13 significant projects that have employed CCS technologies at a large scale. Several of these projects have captured and stored CO2 primarily for commercial motives, such as increasing oil production. Some have sought to demonstrate new or existing technologies in a specific industry or at larger scales, or to gain experience with particular storage geologies. Relatively few have been required to adopt CCS to meet a regulatory requirement. The technical performance and operational challenges recorded by each of these projects are summarised and placed within the context of the diverse motivating factors behind their development.
