Reduction and Utilization of Emitting CO2 by Using Molten Carbonate Fuel Cell (MCFC) Stack for Sustainable Development in Bangladesh

Abstract

Reduction of the CO2 emission from the existing natural gas and coal based power plant is a great challenge. Existing power plants of Bangladesh emit CO2 at a concerning rate. Meanwhile, that causes serious greenhouse effect. But Bangladesh government cannot afford to simply stop producing power from the existing power plants just because they are harmful to the environment. In this research work molten carbonate fuel cell implementation with the existing power plant has been proposed. This proposed hybrid power supply system not only reduces CO2 emission but also produces power by utilizing that CO2. Meanwhile, it makes the existing power plant environment friendly as well. After observation from MATLAB Simulink and COMSOL results it can be concluded that this proposed hybrid power plant is able to reduce CO2 emission by 70% from existing power plant and at the same time by using the reduced CO2, MCFC stack can produce power with an efficiency of 41.19% for a cell number of 1000. In the inverter section for discrete time operation, the maximum efficiency was found to be 59.81%. Again, from the mathematical analysis it was seen that Ghorashal and Ashuganj have the capability of producing 53.46 MW and 16.16 MW respectively. Meanwhile, considering 1 KW to be the maximum demand of each house it is possible to supply 53000 and 16000 houses respectively by using CO2 from both Ghorashal and Ashuganj power plant. Finally, this proposed hybrid power supply system would be a solution to ensure CO2 reduction, utilization and sustainable development in Bangladesh.
