About CCS

Overview

Carbon capture and storage (CCS) involves capturing carbon dioxide that would otherwise be emitted to the atmosphere, compressing it, transporting it to a suitable site, and injecting it into deep geological formations where it will be trapped for thousands or millions of years

CCS process

Carbon capture and storage is also referred to as geological sequestration, or geosequestration, carbon capture and geological storage (CCGS) or carbon dioxide capture and storage.

CCS can be used to store carbon dioxide from the combustion of fossil fuels (oil, gas and coal). Applying CCS to the generation of electricity using fossil fuels can result in significantly reduced emissions of greenhouse gases to the atmosphere. It is one of many processes which can make reductions in greenhouse gas emissions from the combustion of coal (called low emission coal technology).

CCS can be used to capture and store carbon dioxide emitted from a range of other industrial processes, such as the manufacture of cement and some fertilisers, in purifying natural gas, and in conversion of gas or coal to liquids.

While the concept of CCS as a means of reducing greenhouse gas emissions has arisen only in the past decade or so, CCS uses technologies that have been widely practiced in different industries for many years.
