We believe carbon capture utilization and storage (CUS) will play a key role in
global efforts to reduce emissions, while ensuring the world can continue to
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
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
bv turning the as into marketable industrial and commercial products.
Water-based solvents work in an absorption-regeneration loop:
• The industrial gas is fed into the main chamber, where the solvent will react safely and
quickly with carbon dioxide.
• The CO2-rich solvent will then be transferred to a regenerator, where the
temperature will be raised to around 35 degrees Celsius.
• This increase in temperature reverses the carbon dioxide absorption reaction,
producing a pure CO2 gas and fresh solvent.
The fresh solvent can be returned to the main chamber to start the cycle all over again.
• 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
• Finallv, 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.
