Technologies to capture, store and use carbon are gaining renewed interest as a solution to help decarbonise the global economy and reach climate neutrality, especially for industries that use large amounts of energy and don’t have many solutions to limit them.
Collectively known as CCUS – Carbon Capture, Utilisation and Storage – these technologies prevent CO2 escaping into the atmosphere from many industrial processes, and either store it permanently in deep rock formations (CCS) or convert it into useful materials (CCU).
Capturing the emissions uses technologies which either directly capture CO2 from the air or from sources such as industrial plants producing steel and cement. Once it’s captured, the CO2 is then transported to where it can be:
- Permanently stored in underground rock formations, or
- Utilised (reused) as raw materials for products such as biofuels, chemicals and building materials.
