About Carbon Capture and Storage

Carbon capture and storage (CCS) is a process where carbon dioxide (CO2) from industrial processes is captured and stored securely in rocks deep underground, similar to the way oil and gas has been stored for millions of years. Also known as carbon geosequestration, it is being developed by many countries around the world, including Australia.

Why do we need CCS?

Leading scientists and international authorities such as the Intergovernmental Panel on Climate Change and International Energy Agency have identified CCS as having a critical role in helping to reduce our greenhouse gas emissions.
CCS could deliver 13% of cumulative emissions reductions required by 2050 to limit global temperature increases to 2oC, and has an even greater role in meeting the target of limiting temperature rise of 1.5oC.

CCS does not replace the need to increase energy efficiency or develop renewable energy technologies – it is part of a portfolio approach to addressing the issue of greenhouse gas emissions and climate change. CCS is the only technology presently capable of decarbonising many large-scale industrial processes.

How does CCS work?

CCS has four main stages:

  1. Capturing the CO2 from industrial processes
  2. Compressing it into a liquid form
  3. Transporting it via a pipeline to a suitable geological storage site
  4. Injecting the CO2 for permanent storage (geosequestration).

Where is CCS being used?

There are 88 pilot and demonstration CCS projects worldwide which have provided an extensive body of scientific analysis and engineering experience. In addition, there are 22 commercial-scale CCS facilities in operation or under construction. The 17 operational facilities are applied to a wide range of industries such as power generation, syngas, natural gas processing, bioethanol, hydrogen production, iron and steel production and fertilisers.

Interactive world maps showing large-scale facilities, pilot and demonstration plants, test centres and other CO2 initiatives are available at the Global CCS Institute.

Study CCS

For those interested in studying CCS the University of Edinburgh runs a free, five-week 'Climate Change: Carbon Capture and Storage' course through the online edX learning portal, while the University of Melbourne runs an annual advanced course on the Fundamentals of Geological Storage of CO2.
