Carbon Capture and Storage (CCS) is a technology that aims to capture carbon dioxide (CO2) emissions from industrial processes and store them underground, preventing them from being released into the atmosphere. The process involves capturing the CO2 emissions at the source, such as power plants or factories, and then transporting and storing them in geological formations deep underground. CCS is considered a key technology in the fight against climate change, as it allows for the reduction of greenhouse gas emissions while still utilizing fossil fuels.
The process of CCS involves three main steps: capture, transport, and storage. In the capture phase, CO2 is separated from other gases emitted during industrial processes. This can be done through various methods, such as post-combustion capture, pre-combustion capture, or oxy-fuel combustion. Once the CO2 is captured, it needs to be transported to a suitable storage site. This can be done through pipelines or by shipping it in liquid form. Finally, the CO2 is stored underground in geological formations such as depleted oil and gas fields or deep saline aquifers.
