The Social Cost of Carbon Evaluation Based on Carbon Capture and Storage Technologies for Power Generation Plants

Abstract

Power plants produce electricity using high amounts of fossil fuels such as coal. Using these fossil fuels releases very high emissions into the atmosphere. Carbon capture and storage (CCS) applications have been developed to reduce these emissions. Thus, by capturing 96% of the CO<sub>2</sub> formed from the burning of fuels in power plants, the global warming potentials emitted by conventional electricity generation can be reduced by up to 80%. The study investigated applications of CCS options to reduce emissions during electricity generation, CO<sub>2</sub> emissions, pre-combustion, post-combustion, and oxyfuel coupled global warming potentials. The reCiPe midpoint method has been taken into account for CO<sub>2</sub> emission. CCS options calculate the reduction in global warming potential. The study accepts that hard and brown coal is used as fuel in power plants that produce electricity. Finally, for the three cities with the highest electricity consumption in Turkey, the global warming potential emission in conventional electricity generation power plants burning brown coal is calculated as 43.4 kilotons for plants burning brown coal. It has been calculated as 6.2 kilotons in power plants using oxyfuel CCS and burning hard coal. Ten-year life for Istanbul, for hard coal burning and pre-combustion related discount rate of 1% and 3 $/ton social cost of carbon; The social cost of carbon is calculated as $102.8 million.
