From Coal-Fired Power Plants Using Calcium Looping

105 Atmospheric carbon dioxide (CO2) levels have risen from about 280 to 390 ppm following the industrial revolution and rapid progress since then. This increase along with changing weather patterns has caused some alarm and subsequent thrust in research activities in the fields exploring the role of CO2 in climate change as well as strategies to reverse the increasing trend in atmospheric CO2 concentration. Global energy demand is predicted to increase by about 50% in the next 20 years and carbon-intensive fossil fuels (such as coal, oil, and natural gas) will continue to supply the majority of this energy. Consequently, CO2 emissions are also predicted to rise considerably, and thus, it is necessary to develop effective and economical methods of controlling the same.
