Carbon capture utilisation and storage (CCUS) refers to the matching of industrial high-purity CO2 sources, such as those of fertiliser plants or coal-to-liquid fuels facilities, with a sink industry that would make beneficial use of the captured and transported CO2, such as enhanced oil recovery (EOR). The capture of CO2 from industrial high-purity sources requires much less additional process development than conventional carbon capture from the power generation industries. Similarly, the sink industries may require less development than conventional CO2 storage in geological formations like saline aquifers; hence, CCUS does not refer here to conventional carbon capture and storage.
