Several carbon capture and sequestration (CCS) processes hold much promise, and there are challenges yet to be met A number of post-combustion carbon capture technologies have the capability to reduce the amount of carbon dioxide emitted to the atmosphere from fossil-fuel-fired industrial and utility-power plants. Further interest has been placed in this technology in light of growing concerns about climate change. This article investigates a few of the more promising post-combustion carbon capture processes, including amine-based absorption, ammonia-based absorption, solid sorbent adsorption, membrane filtration and algae. This article also considers some of the challenges associated with compression, transportation and storage of carbon dioxide. Carbon dioxide in the atmosphere is a greenhouse gas that most scientists consider to be largely responsible for climate change. Among the most significant sources of atmospheric CO2 is fossil-fuel-fired power generation. For many years, technologies for carbon capture and sequestration (CCS) have been under investigation and development as a means of mitigating CO2 emissions while still allowing industries to burn fossil fuels. Currently, three of the most promising techniques for CCS are…
