We believe carbon capture utilization and storage (CCUS) will play a key role in global efforts to reduce emissions, while ensuring the world can continue to thrive.

How does CCUS work?

CCUS technologies capture CO2 emissions at source or directly from the air. CO2 emissions are then transported away and stored deep underground or turned into useful products.

Capturing carbon has been used for decades to help improve the quality of natural gas, but pioneering new technologies mean we can now remove and sequester CO2 indefinitely. Moreover, we are exploring new ways to add value to waste CO2 by turning the gas into marketable industrial and commercial products.


What CCUS technologies are available?

Capture technologies take CO2 from exhaust or reformed gases or stationary sources using pre-combustion, post-combustion or oxy-combustion techniques
Sequestration technologies deposit captured CO2 in geological formations
Enhanced Oil Recovery involves extracting oil from oil fields by changing the original properties of oil, such as chemical flooding, carbon dioxide injection, or thermal recovery
Utilization means using captured CO2 directly – for example in manufacturing cement – or converting captured CO2 and other gases into useful industrial products like chemicals or fuels
Mobile Carbon Capture technologies capture CO2 from mobile sources and store the gas on board, ready for sequestration or utilization
Direct Air Capture processes capture CO2 directly from the atmosphere (rather than at source), to be sequestered or utilized
Bio Energy Carbon Capture and Storage technologies extract and store CO2 from biomass, itself a renewable energy source
Finally, nature can act as a natural carbon sink. Mangrove trees, for example, sequester carbon far more effectively and permanently than terrestrial forests. Alternatively, CO2 can be sequestered by cultivating algae, which can be harvested and processed to produce useful products like biofuel and protein-rich animal feed.
