Introduction
With the rapid development of modern civilization, the widespread use of fossil
fuels within the current energy infrastructure is considered as the largest source of
anthropogenic emissions of CO2, which is largely responsible for global warming
and climate change
The International Panel on Climate Change (IPCC) predicts that, by the year 2100,
the atmosphere may contain up to 570 ppm CO2, causing a rise in the mean global
temperature of around 1.9 C
CCS is not the „silver bullet‟ that in and of itself will solve the climate change
problem, it is powerful addition to the portfolio of technologies that will be needed
to address climate change

Fossil fuels will continue to be used in absence of any fast and easy alternatives
used at large scale
CCS enables to continue use of fossil fuels with reduced emissions while other
alternatives are being developed
CO₂ capture technologies are commercial and widely used in industrial processes
mainly in petroleum industries, ammonia processing and natural gas refining
Applied to several gas fired and coal fired boilers but at smaller scales than current
power plants

• Small Scale: Demonstrated in several industrial applications but not yet at a modern
electric power plant of capacity of as high as 500 MW
• Energy Penalty & High costs involved for the implementation of CCS (CO₂separation, compression, delivery in pipeline and injection of compressed CO₂ in
geologic reservoirs)
