What is CCS?

CCS stands for Carbon Capture and Storage

Geologic storage of carbon dioxide (CO2) is the underground storage of CO2 from large industrial sources such as power plants and other industrial sources.

Carbon Capture and Storage (CCS), also known as Carbon Capture and Sequestration, includes geologic storage as one of its components.

Carbon capture and storage is a process for reducing GHG emissions into the atmosphere by first extracting CO2 from gas streams typically emitted during electricity production, fuel processing and other industrial process. Once captured and compressed, the CO2 is transported by pipeline or tanker to a storage site, often to be injected into an underground storage site (or geological formation), where it will be safely stored for the long-term.

It's important to remember that CO2 will be stored in the sub-surface one to two kilometres below the surface, where gases and liquids have been stored securely for millions of years.

Site selection and project development are key to successful CCS projects as they determine where the best geological traps exist, how a project can be developed to make responsible use of the traps, while ensuring the safety and security of the CO2 being injected to the deep geological formation.  

Processes that are so technical and hard to envision can make the technology hard to understand.  Several different companies, media and government agencies have created animations to assist with "Simplifying the Technology". 


There are three parts to CCS:  

  • capturing CO2 from large industrial sources,
  • transporting the captured CO2 to suitable storage locations, and  
  • injection of the CO2 for permanent storage into a deep geological formation.
