Life-Cycle Impact Assessment of Fossil Power Plants with and without Co2 Capture Evaluating the Possibility of Co2 Utilization

The CO2 emission is more than 36 billion tons per year in global scale. As carbon dioxide raises temperature by trapping solar energy the atmosphere, research ongoing to facilitate capture of with high efficiency. While footprint Bangladesh relatively low, upcoming coal-based power plants (>17000 MW) next decade, fossil will increase significantly. To understand underlying benefit process, cradle-to-gate life cycle impact assessment (LCIA) using sources (e.g. natural gas, coal) can provide an in-depth insight. This paper aims conduct on gas and coal (sub critical supercritical) fired without facility for comparison overall environment. An open source software titled OpenLCA was used carry out LCIA study different parameters (i.e. green-house emission, toxicity ozone layer depletion). It found that from super-critical pulverized (SCPC) sub-critical (Sub-PC) could be brought down 80% facility. Along capture, it equally important ensure proper sinks this captured CO2. has no dedicated geological reservoir storage, potential sink immediate utilization after capture. also presents preliminary results utilizing through mineralization during preparation alternative admixture construction materials. Due ever-growing real-estate sector Bangladesh, there great capturing activities.
