Techno-economic Assessment of Indian Power Plant Retrofitted with Calcium Carbonate Looping Capture Method

Abstract

The increase in concentration of carbon dioxide (CO₂) into the atmosphere has now become a serious threat to the world. Agriculture is now getting badly affected due to changes in weather pattern which is caused by the presence of huge amount of CO₂, a potential greenhouse gases (GHG). Developing country like India where agriculture and services play a major role in the GDP is more concerned about the global warming. Major source of CO₂ emission in India is thermal power plant, which accounts for almost 65% of CO₂ being emitted into the atmosphere. So implementation of CO₂ capture unit with minimum cost in thermal power plant is very necessary in order to cut the emission of CO_2. In this paper, techno-economic assessment of carbon capture unit in thermal power plant of India is performed using IECM software developed by the Department of Energy, Carnegie Mellon University, USA. It is estimated that the implementation of calcium carbonate looping combustion method of carbon capture will increase the total amount by almost Rs. 2687/MWh. This amount can be reduced by utilizing and selling the stored CO₂ to different industries.
