While Carbon Capture and Storage (CCS) technologies are being developed with the focus of capturing and storing CO₂ in huge quantities, new methods for the chemical exploitation of carbon dioxide (CCU) are being developed in parallel. The intensified chemical or physical utilization of CO₂ is targeted at generating value from a limited part of the CO₂ stream and developing better and more efficient chemical processes with reduced CO₂ footprint. Here, we compare the status of the three main lines of CCS technologies with respect to efficiency, energy consumption, and technical feasibility as well as the implications of CCS on the efficiency and structure of the energy supply chain.
