CARBON CAPTURE & UTILISATION TECHNOLOGIES

CARBON CAPTURE & UTILISATION TECHNOLOGIES

TOPIC: Science & Tech.

Context- Most carbon capture and utilisation (CCU) technologies, which suck carbon dioxide (CO2) from the atmosphere and convert it into fuel or other valuable products, might fail to help the world reach Net Zero emissions by 2050, according to a new study.

Concept-

Carbon Capture, Utilization and Storage (CCUS):

• CCUS technology is designed to capture CO2 emissions from combustion of fossil fuels.
• It can absorb 85-95% of CO2 emissions in the atmosphere.
• The process starts with the capture of generated CO2 which undergoes a compression process to form a dense fluid. This eases the transport and storage of the captured CO2.
• The dense fluid is transported via pipelines and then injected into an underground storage facility.
• Captured CO2 can also be used as a raw material in other industrial processes such as bicarbonates.
• CO2 captured using CCU technologies are converted into fuel (methane and methanol), refrigerants and building materials. The captured gas is used directly in fire extinguishers, pharma, food and beverage industries as well as the agricultural sector.
