Rapid global deployment of carbon capture and storage (CCS) requires a two-track approach. CCS needs to be deployed at scale as quickly as possible and other plants, if built without CCS, need to be built CO 2 capture ready (CCR) before they are retrofitted. In particular, coal plants are likely to continue to be built in large numbers in …
