What is CCS ?

Global warming is one of the greatest challenges humanity has ever faced, and urgent measures are necessary to achieve the magnitude of CO2 emissions reduction required to stabilize and reduce atmospheric concentrations of greenhouse gases (GHGs).

Stabilization of CO2 emissions can be best achieved through the development of a portfolio of solutions, including energy efficiency measures; increased use of renewable energy sources and the decarbonisation of power generation from fossil fuels through CO2 capture and storage (CCS).

 

Carbon capture and storage (CCS) is a process whereby CO2 emitted from large stationary emission sources is captured and stored safely underground.

Capturing CO2 means separating it from the other components of the exhaust from sources such as coal-or gas fired power plants.
Storing CO2 involves compressing the CO2 gas and then transporting it by pipeline or ship to a suitable location where it can be stored deep underground in a variety of geological settings.

 

There are several types of storage sites that are well suited for CO2 storage. The most important characteristics of a good geological storage site are the presence of porous rock in which the CO2 can be stored (much like water is held in a sponge), and an impermeable seal that prevents the escape of CO2. The most common types of site will be old oil and gas fields and deep, water-filled formations.
