| Abstract | In India, about 59% of electricity is generated using coal. As coal acts as a primary source of energy in India as well as in Andhra Pradesh, power plants release huge harmful emissions into the atmosphere which leads to global warming. So, there is a need to mitigate these emissions, one of the technology is to capture carbon and store geologically. This study evaluates the suitable CO2 storage location near the power plant so that captured CO2 from the power plant can be transported easily and stored under geological formations permanently. Saline Aquifers were selected as the best option in permanently storing the CO2 due to mineral and carbon dioxide interactions. KG basin is the suitable area for storing the captured CO2 from the selected power plant which has huge CO2 storage potential. This study evaluates the appropriate carbon dioxide capture system for the coal based power stations in Andhra Pradesh. The study is based on various specifications like energy penalty, efficiency, price of electricity, cost of capture system etc. IECM software version 9.1 is used for simulating the base power plant and to carry out calculations such as energy penalty, the price of carbon capture and incremental price of electricity. Depending on different carbon capture technologies the net plant efficiency varies. The plant efficiency is reduced from 29% of the base plant to 21%, 19%, 17% and 10% if the plant is retrofitted with the amine, ammonia, oxy-fuel and membrane based capture technologies respectively. The energy penalties with installation of CCS will be low for the power plants with less age i.e. below 15 years and CCS system also works with better pace. The retrofitting of power station with various capture systems will decrease the net electricity yield of the power station. The values of incremental cost of electricity (COE)for various capture systems are estimated to be varying between INR 1.7-11.9/kWh. The incremental costs of electricity for amine, ammonia, membrane and oxy-fuel capture systems are 1.7Rs/kWh, 4.3Rs/kWh, 11.9Rs/kWh and 3.06Rs/kWh respectively. Thus, it is worthy to investigate on the carbon capture system suitable for installing in power plant and nearest possible CO2 storage location sites. |
