The hydrogen, methane, carbon monoxide and CO2 are then siphoned off through a second borehole. Decision in this regard was taken by Union Cabinet Committee meeting chaired by the Prime Minister Narendra Modi in New Delhi. Syngas from UCG can be used as a feed stock for CTL for production of clean synthetic liquid fuels using Fischer Tropsch process. Integrated coal gasification combined cycle is a promising and a high efficiency power generation technology which gasifies coal and makes use of this gas and waste heat to make the turbines run and thereby improve thermal efficiency. • Gas can be used to produce synthetic natural gas. The usage of locally available coal for making fertilizers would help reduce the import of LNG. Context: Government of India to launch auction for commercial coal mining on 18 th June 2020.. • In UCG process, ash/ slug removal is not required as they remain in the cavities. To access the same, a google account is a must. The syngas can be used in a variety of applications such as in the production of electricity and making chemical products, such as … Most Important UPSC IAS topics for UPSC Exam 2021:... UPSC Mains Test Series ! CH4 and CO2 are the other two major products and their content goes up with increasing pressure and H2+CO content going down. In News- Recently, the Government of India(GOI) opened commercial coal mining for the private sector through auctions of 41 coal mines which are designed to boost production, reduce imports and raise state revenues. FREE. Transporting gas is a lot cheaper than transporting coal. • Cost of production for this energy resource could be as low as US$ 1.0-1.5 per MMBTU. 8) Unlike coal-bed methane, therefore, the actual coal is converted from a solid state into gas. Recently Odisha’s Talcher fertilizer plant was awarded a contract for starting a coal gasification unit for the production of urea and Ammonia. CIL, NLC, SCCL, GMDC and GIPCL. ; The government had announced that it would remove the government monopoly on coal mining by introducing commercial mining on a revenue sharing basis. Commercial coal mining. Case study: cougar energy plant Queensland (Australia) exploded and subsequently benzene was found in ground water. • Compared to traditional coal mining and processing, the underground coal gasification eliminates surface damage and solid waste discharge, and reduces sulfur dioxide (SO2) and nitrogen oxide (NOx) emissions.What are the disadvantages of UGC? Extraction is complicated because of environmental issues. The decision is geared towards reducing India’s reliance on imports and helping the country meet its CoP-21 Paris Agreement commitments. • UCG produces insignificant surface disruption and brings no solid waste to the surface. Coal gasification is the process of converting coal into synthesis gas (also called syngas), which is a mixture of hydrogen (H2), carbon monoxide (CO) and carbon dioxide (CO2). • ONGC has taken Skochinsky Institute of Mining, Russia, and world’s foremost leaders in UCG Technology, as its technical collaborator. From UPSC perspective, the following things are important : Mains level : Benefits of Coal Gasification. • UCG reduces capital investment, operating costs, and the output gases cost by 25 to 50% as compared to surface gasification. India is well positioned to take up UCG for extracting energy from isolated geographical locations. Coal gasification is the process of converting coal into synthesis gas (also called syngas), which is a mixture of hydrogen (H2), carbon monoxide (CO) and carbon dioxide (CO2). What is Underground coal gasification? Ƒ. The oxygen and water within the coal seam react with the coal to produce syngas, which is withdrawn through a production well. What is underground coal gasification process? • UCG offers an environmentally clean way to harness energy from coal. The Union Cabinet has approved a policy framework for development of Underground Coal Gasification (UCG) in unexplored coal and lignite bearing areas in the country. This was stated by Sh. India’s CBM potential is estimated at 450 tcf.
