COAL GASIFICATION AND RECENT ADVANCES IN CARBON REDUCTION EMISSION: A REVIEW

Global warming and the change in the climate with limited availability and increase in the cost of energy are posing challenges for the sustainability of the global digital- economy. As due to the increase in energy consumption the carbon dioxide emission has increased several times especially in the developing countries which are undergoing the development of industrialization. Coal gasification has emerged out to be as a clean coal technology, it utilizes coal more effectively for power generation thus, meeting the stringent environmental regulations. Coalgas technologies are bound to be adopted for electricity generations which in turn reduces the level of CO2 emission and finally in the reduction of global warming. In addition to the this, various technologies are used in the reduction of the carbon emission to the atmosphere likecarbon capture, geoengineering schemes, biological carbon dioxide mitigation, reduction techniques adopted by various industrial, building and agricultural.Wide range of literature is available on the carbon emission reduction and in this paper an attempt has been made to compile about the various technologies used in the reduction of carbon dioxide emission.
