HOW CCS WORKS
 

Energy generated from fossil fuels such as coal, oil and natural gas releases CO2 to the atmosphere as a by-product.To reduce CO2 emissions to the atmosphere, CO2 capture technology can be applied to any large–scale emission process, including coal–fired power generation, gas and oil production, and manufacture of industrial materials such as cement, iron, steel and paper pulp. In fact, large CO2 emitting industries around the world have applied the capture technology for decades. Captured CO2 is used, for example, in the food and beverage as well as fertilizer industries.

In systems where the coal is pulverized to a powder, which makes up the vast majority of coal–based power plants in North America, Australia, Europe and China, the CO2 must be separated at fairly diluted concentrations from the balance of the combustion flue gases (gas exiting via a chimney or ‘flue’). In other systems, such as coal gasification, the CO2 can be more easily separated.

 

CCS Process

·         Instead of being released into the atmosphere, CO2 is captured from emission sources and is compressed.

·        The compressed carbon dioxide is pumped through a network of pipelines, some new and some formerly used for other purposes, to a suitable well.

·         The carbon dioxide is pumped through the well into geological formations with porous rocks that can contain the CO2 permanently

·        The carbon dioxide filters into the porous geological formation where typically is trapped by the cap rack which is a solid impermeable type of rocks (seal).
