Carbon Capture, Utilization and Storage (CCUS)
Carbon Capture, Utilization and Storage (CCUS) refers to technologies that capture carbon dioxide (CO2) emissions from large stationary sources like power plants or industrial facilities that use fossil fuels. The CO2 can then be securely and permanently stored underground or converted for utilization in manufacturing products.
CCUS Technologies
Specific CCUS technologies include:
- Direct air capture of CO2 from ambient air
- Capture of CO2 from flue gas or fuel gas from large point sources
- Transportation of captured CO2 via ships or pipelines
- Underground injection and geologic storage of CO2
- Conversion of CO2 into value-added products
Key Industry Applications
CCUS has vital decarbonization applications for hard-to-abate carbon-intensive sectors:
- Steel, cement, oil, gas, chemicals, fertilizers
- Enables clean production despite coal utilization
- Promotes self-reliance and reduces import dependence
CO2 Utilization Potential
Captured CO2 can be utilized for diverse products:
- Fuels like methanol and ethanol
- Chemicals like bioplastics
- Building materials including concrete
- Enhanced oil recovery
- Food and beverage applications
- Green hydrogen production
Economic and Employment Benefits
CCUS projects can yield economic growth and jobs:
- 750 million tonnes of CO2 capture potential by 2050
- 8-10 million associated full-time job opportunities
- Enables sustainable growth across industries
Thus CCUS is vital for achieving development priorities along with climate change mitigation.
