The burning of fossil fuels for energy is the main cause of human induced Climate change. The carbon stored within coal, gas and oil is released into the atmosphere when burnt to generate energy. A potential alternative to releasing the carbon dioxide into the air is to capture at stationary power sources and store in underground geological formations including disused oil wells. Along with other options of sequestrating within carbon sinks in forests and oceans. This approach is called Carbon, Capture and Storage (CCS).
The potential of this type of technology is immense. Coal provides high amounts of energy on combustion; reserves are widely and easily distributed all over the world. Also, as coal combustion is a very large source of human induced carbon dioxide emissions, the imperative to get this technology past demonstration into commercial scale is high.
Post-combustion capture (PCC) can capture CO2 emissions from pulverised fuel stations using a chemical solvent.[1] The 'scrubbed' gas is released into the atmosphere and the CO2 is transported for storage.[2]
