Carbon Capture and Storage (CCS)
A suite of technologies for extracting CO2 from emission sources or ambient air and storing it in geological formations, preventing atmospheric accumulation.
Real World
The Sleipner CCS project in Norway, operational since 1996, injects around one million tonnes of CO2 per year into a saline aquifer beneath the North Sea, making it the world's longest-running commercial CCS facility.
Exam Focus
In 'assess' questions, always weigh CCS against cost and energy penalty — it currently uses 15–25% of a power plant's output, weakening its net benefit argument.
