Final answer:
Carbon capture and storage (CCS) involves separating carbon dioxide (CO₂) from the environment and storing it permanently underground.
Step-by-step explanation:
Carbon capture and storage (CCS) involves separating carbon dioxide (CO₂) from the environment. CCS is a process used to capture the CO₂ emitted from sources like coal-fired power plants and store it deep beneath the Earth's surface. The captured CO₂ is injected into porous rock formations and sealed below an impermeable layer, where it remains permanently.
