Overview

WHAT IS CARBON CAPTURE AND STORAGE?

Carbon dioxide (CO2) is emitted when fuels such as coal, oil and natural gas are used. Carbon capture and storage (CCS) is a process used to prevent these COemissions from entering the atmosphere and contributing to climate change.

CCS captures CO2 at a power station or industrial facility such as a steel, LNG or cement plant. The captured COis then stored safely and permanently in deep underground geological structures, or by other physical, chemical or biological means.

CCS also mimics natural examples where gases, including CO2, have been trapped in deep geological structures for millions of years.

Carbon capture and storage is focused on stationary sources as it is not yet possible to capture CO2 from mobile sources such as cars, trucks and aeroplanes.

HOW DOES THE CSS PROCESS WORK?

CCS is a proven technology which includes four stages (click the numbers for more detail):

Is the technology proven?

Yes. CCS is already being used successfully across the world. CO2 capture, transport and storage technologies are used in oil and gas sector projects in Canada (Weyburn-Midale) and Norway (Sleipner), where COhas been injected since 1996 and 2000 respectively. Two coal sector CCS projects have commenced operation recently: Boundary Dam (Canada, 2014) and Petra Nova (USA, 2017).
