6. Carbon Capture and Storage (CCS): Mitigating the Effects of Climate Change
Capturing Carbon to Protect the Planet
Carbon capture and storage (CCS) technologies aim to capture carbon dioxide (CO2) emissions from industrial sources and power plants, preventing them from entering the atmosphere and contributing to global warming.
Challenges:
- Cost and Energy Requirements: The process of capturing and storing CO2 is energy-intensive and expensive, which has hindered its widespread implementation.
