Carbon capture and storage, or sequestration (CCS), is the long-term isolation of carbon dioxide from the atmosphere through physical, chemical, biological, or other engineered processes. This includes a range of approaches including soil-carbon sequestration (e.g., through no-till farming), terrestrial-biomass sequestration (e.g., through planting forests), direct injection of CO 2 onto the deep seafloor or into the intermediate depths of the ocean, injection into deep geological formations, and even direct conversion of CO 2 to carbonate minerals. All these processes are considered in the 2005 special report by the Intergovernmental Panel on Climate Change (IPCC, 2005). Anthropogenic activities like industrialisation, deforestation, forest degradation and burning of fossil fuel, has caused an increase in the level of carbon in the atmosphere and disrupted the global carbon cycle (Solomon and Srinivasan, 1996). Climate change or global warming due to the rise in greenhouse gases, primarily carbon dioxide (CO2), is one of the most urgent global problems. If not addressed properly can cause irreversible and disastrous damage to the whole biosphere. Therefore, varieties of strategies are needed to reduce CO 2 emissions and remove carbon
