Coalbed Methane: A Clean Energy Source Coalbed Methane is a hydrocarbon and a by-product of coalification process. CBM and its subsets, viz. ,CMM, AMM, VAM are globally an emerging environment-friendly alternate energy resource. Utilization of CBM resource will be very environment friendly as harnessing methane ahead of mining (CMM) : Ensures future mining safe for gassy mines, Prevents release of methane to the atmosphere Provides additional energy from the otherwise wasted resource.
CBM Development in India - A historical account • In India CBM activities started in early 90’s. • CMPDI on behalf of M/s AMOCO, USA examined the prospect of CBM in Damodar Valley CF. The matter however did not proceed further due to operational difficulties perceived by AMOCO. • The real thrust in development of CBM came with the announcement of CBM Policy in1997 by the Govt of India. • MoP&NG has been made the administrative ministry for CBM development in the country. • Several investor friendly fiscal incentives were announced in the CBM policy which attracted international attention • As per CBM policy, blocks for global competitive bidding were to be carved out in consultation with MoC.
Block delineation under CBM Policy : CMPDI’s role • Govt. of India has so far allotted 33 CBM blocks covering an area of about 17366 Sq. Km with prognosticated resource of 1.78 TCM in 4 rounds of global bidding. • Going by an estimate, the ultimate production potential in the allotted blocks is about 45 MMSCMD, which may support power generation of about 8300 MW. • Data dossiers for most of these blocks have been prepared by CMPDI. • CMPDI is preparing Data Dossiers for forthcoming 5th Round of allotment of CBM blocks • Commercial production has already started in few blocks and at present over 2.5 lac cubic metre of CBM is produced per day. .
Implementation of Commercial CBM Projects by CMPDI CIL-ONGC CBM Collaborative Project Govt has allotted 2 CBM blocks (Jharia and Raniganj) for commercial development. CMPDI/CIL carried out exploratory drilling and all related tests while ONGC undertook appraisal drilling. On the above studies, these fields have been found to be commercially viable Commercial Development Plan for both the CBM Blocks submitted for approval of the Govt.
CBM specific data generation • CMPDI is generating CBM related data under PRE programme of MoC for enlarging CBM resource base • Studies have been carried out in 71 boreholes(CMPDI 51;GSI 21) during X and XI plan • In XII plan :CBM studies in 40 boreholes to be carried out by CMPDI, 5 completed
Commercial development of CMM: A Priority area CMM is harnessing of methane from active/projectised coal mining areas. In terms of methane emissions, India ranks 6th globally with 1 BCM (14.3 MT CO2e) of CMM emissions (2005) CMM constitutes a significant global source of anthropogenic methane emissions. Harnessing and gainful utilization of CMM and VAM is a priority area both at Govt and industry level. GOI has made CMPDI a Nodal Agency for development of CMM in India.

Commercial Development of CMM in CIL Areas • CMPDI has identified five blocks, 3 in Jharia and 2 in East Bokaro coalfield, within CIL command areas for commercial development of CMM through a R&D initiative.
Commercial Development of CMM : Opportunities & Challenges • CMPDI on behalf of CIL floated tender for selection of suitable developer. • Certain issues regarding operationalization were raised by MoP&NG and the matter is under deliberation between MoC and MoP&NG. • MoP&NG agreed to facilitate development of CMM by CIL in its mining leasehold areas in a meeting held on 17/8/2012 between Adviser, MoC and Secretary, MoP&NG and necessary steps for the purpose is being taken by MoP&NG. • CMPDI on behalf of CIL will float a fresh tender after resolution of the issue.
Underground Coal Gasification (UCG) Offers potential means of extracting energy from coal deposits which are not amenable for physical extraction economically at present by conventional methods. The low heat value gas produced from UCG can be used for power generation and can as well be used as a feedstock for chemical industry. Environmental advantages in application of UCG are: Minimum surface disturbances No problem for ash or slag disposal Reduced CO2 emission No production of pollutant. It gives green energy.
UCG Development: Recent Initiatives To expedite development of UCG, the following activities were taken up by CMPDI as part of the MoC initiatives: Fixation of criteria for selection of suitable UCG reserves in consultation with GSI, DGMS, SCCL and NLC Selection of suitable lignite / coal blocks in consultation with NLC, GSI, SCCL. Accomplishments: Criteria arrived at in consultation with other organizations. A list of 7 blocks (5 lignite and 2 coal) identified in consultation with NLC, GSI, SCCL after getting it examined by standing committee of CMPDI. The list forwarded to MoC for taking further necessary action for development of UCG
Development of UCG in CIL Areas • Development of UCG with ONGC • CMPDI on behalf of CIL is pursuing development of UCG in Kasta Block in RCF under collaborative regime with ONGC. • Additional UCG specific data through exploratory drilling generated and being assessed for examining pilot scale studies. • Report based on the aforesaid data has been sent to ONGC for examination by Russian experts engaged by ONGC.
