Background

For ensuring energy security, country is exploring harnessing of all possible energy source.

There is also an impetus on the development of clean energy resources.

Related synergic field of CBM, CMM, UCG and Shale Gas etc. fits in this ambit.

Development of these energy resource will be beneficial for coal industry in safety and fiscal terms as well as on environment front.

CMPDI has developed technical expertise in these fields and has established itself as a premier consultancy organization, nationally and internationally

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. .

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 : 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

Shale Gas

Shale gas is natural gas occurring within shale formation, which acts

as source as well as reservoir.

Shale Gas mainly constitutes of methane and originates from

organic constituents present in shale rock.

Presently, USA is the only country producing commercial shale gas and

several other countries are pursuing its development.

Government of India is also actively considering for the development of

shale gas potentiality in India.

CMPDI is having state of art CBM lab which is capable in taking up all the parametric tests for evaluating CBM resource viz. Desorption studies, Gas composition & Adsorption Isotherm.

In Sept. 2011, an Adsorption Isotherm equipment capable of generating pressure up to 20 Mpa (approx 2000m depth) has been installed in the lab. Probably only equipment of such capacity in India.

Mine air analysis is also carried out and during 2011-12, 1100 samples were tested.

The lab is in process of acquiring shale gas testing equipments so that shale gas specific tests could be carried out.

yFuture Perspective

To implement commercial projects on development of CMM in CIL areas keeping in view overall advantages on account of: Making future mining safe Harnessing of Environment friendly clean energy resource Revenue generation

Implementation of UCG projects is also a priority area.

These are also in line with the strategic plan of Ministry of Coal, Government of India, wherein the following recommendations have been made:

1. CIL to take lead for commercial exploitation of CMM from its leasehold areas

2. CIL to concentrate on areas like CBM and UCG in their leasehold.

Conclusion

Renewable energy resource and other coal based non-conventional energy resource viz, CBM, CMM, UCG, shale gas etc needed to bridge the gap of demand- supply demand of energy in India.

Development of CMM is an area which requires serious consideration, as it will give fresh impetus in coal mining as well as provide environmental benefits. Addressal of issues particularly matters related to operationalisation needs early resolution.

To encourage development of CMM, several countries like China, Ukraine etc have announced several fiscal incentives and also issued legislations. Such incentives may be considered in our country also.

There is also need for initiating development of other resources viz VAM, Shale Gas ,UCG,etc.
