Life cycle assessment of carbon capture and storage in saline aquifers for coal-fired power generation: An Indian scenario

Human activity is causing an increase in the atmospheric concentration of greenhouse gases (GHGs) resulting in global climate change. The use of carbon capture and storage (CCS) in energy supply systems is one method of reducing GHG emissions. Three pulverized coal-fired power stations near the Krishna-Godavari basin with and without CCS have been evaluated using the life cycle assessment and economical approach. Mono-ethanolamine (MEA) postcombustion CO2 capture, compression, transportation with the pipeline, and storage in the Krishna-Godavari basin are all part of the CCS system. Up to 89% of power plants' CO2 emissions can potentially be reduced. The retrofitting of a CO2 capture unit into a power plant adds the most to emissions and the cost of the CCS system. There is a 66% rise in the electricity cost when CCS is implemented in an existing power station, with a capital cost of about US$3.4billion.
