Carbon Capture

Definition

Carbon capture, utilization, and storage (CCUS) is a process that captures carbon dioxide (CO2) emissions from sources like power plants or industrial facilities and either reuses or stores it so it will not enter the atmosphere.

Why It Matters

CCUS is considered a potentially important technology for decarbonizing heavy industries and mitigating climate change, especially for processes where emissions are hard to avoid.

Contextual Example

A large power plant could be fitted with a carbon capture unit that separates CO2 from its exhaust gases. The captured CO2 is then compressed and injected deep underground into geological formations for permanent storage.

Common Misunderstandings

• CCUS technology is still expensive and faces challenges in scaling up.
• It is seen by some as a necessary tool for climate mitigation, while others argue it distracts from the primary goal of transitioning away from fossil fuels.
