Carbon capture and (utilization or) storage is the last CO₂ mitigation option that we are going to see this week. CO₂ generation cannot always be prevented and in order to avoid its immediate release into the atmosphere, it can be stored permanently, or used before its re-release.

Key takeaways:

• CO₂ is both, a waste product and a potential feedstock
• The main components that constitute a CC(U)S system are capture, compression, transport, storage/reuse
• CCS potentially results in permanent storage of CO₂, while CCU mainly results in delayed emissions (mitigating CO₂ emissions whenever the reuse of CO₂ sufficiently reduces CO₂ emissions by displacing the use of other types of carbon)
