Draft Coal Policy: A Stepping Stone
Saleque Sufi
Energy & Mineral Resources Division (EMRD) of the Ministry of Power, Energy &
Mineral Resources (MOEMR) entrusted the task of formulating Coal Policy for
Bangladesh upon Infrastructure Investment Facilitation Centre (IIFC). They have
accomplished their primary task and had let out the draft Coal Policy on website
seeking email comments in an effort to supplement and refine the draft. The
revised draft policy has been circulated among EMRD and other related agencies
for comments and opinions for incorporation in the draft policy.
The latest version of the draft policy (version-2) is to be circulated among the
civil society, academia and other ministries, inviting them to a workshop. IIFC
will organize the workshop, receive, review and collate all the comments arising
from workshop and incorporate in the revised coal policy (version-3). The draft
policy will then be circulated among potential coal investors, business leaders,
chambers of commerce inviting them to a second workshop. IIFC will receive,
review and collate all the comments arising from the workshop and incorporate
them into another revision of draft coal policy (version-4).
IIFC will circulate version-4 among various agencies of EMRD for final opinion
and comments which upon review would form the part of version-5 of the draft
coal policy. EMRD will process the draft for approval of relevant authority.
Given the political reality, bureaucracy, very limited hands on experience and
exposure to coal industry and business EMRD will be very lucky to formulate and
place the draft policy for approval during the currency of present government.
However, undersigned accessed the IIFC website, downloaded the draft policy,
thoroughly examined and reviewed the policy side by side with the coal policies
of Australia, India, South Africa and Sri Lanka. Dr Nafis Ahmed our course mate
in Chemical Engineering Department of BUET, now based in Jakarta as UNESCO
consultant, obtained his PhD from London School of Mines and served for several
years in New Castle University of Engineering, Sydney, Australia in the capacity
of Dean of Faculty of Engineering. We exchanged views over email as he studied
the mining options of Bangladesh during his post graduate study and got deeply
involved in Australian coal industry. His wife Farjana by the way served in
Australian office of BHP, which worked in Bangladesh coal exploration at
Phulbari. Farjana now works for ADB in Jakarta.
Undersigned also obtained opinion of Dr Nishantha Nanayakkra of Sri Lanka who
has extensive experience of world trading of coal. Several references were
obtained from various websites. Based on above and after extensive study over
the last four weeks undersigned attempts to anatomize the current version of the
draft coal policy.
One must bear in mind that Bangladesh energy industry is dominated by indigenous
natural gas, imported liquid petroleum and imported coal. Only 8 percent of the
people have direct access to natural gas and about 30 percent have access to
electricity. The quality of electricity supply is diabolic to speak the least.
Due to resource constraint and bare minimum exploration activities proven and
probable reserve of natural gas may run out soon if we fail to embark upon
extensive exploration on both onshore, offshore frontiers without any further
delay.
Reliable power supply is the essential prerequisite of industrial growth and
economic development. To sustain the present GDP growth rate quality power at
affordable cost must be made available to our majority population. Otherwise all
our efforts for achieving Millennium Development Goal (MDG) towards poverty
allegation will blow with the wind. 90% dependence of power generation on
natural gas may prove disastrous if we cannot reschedule our power generation
fuel mix as soon as possible. Bangladesh reportedly has a total estimated mine
able reserves of 1400 Mt of high heating value, low ash bituminous coal which
upon aggressive mining can comfort our overstressed natural gas and concurrently
add a very valuable item in the export basket.
Basics of Coal
Considering our limited exposure, experience and knowledge of coal it is
considered prudent to refresh our knowledge on coal. Coal is a fossil fuel
extracted from underneath the surface by deep mining, coal mining (open-pit
mining or strip mining). It is composed primarily of carbon and hydrocarbons,
along with assorted other elements, including sulfur. Often associated with the
Industrial Revolution, coal remains an enormously important fuel and is the most
common source of electricity worldwide. Even in the United States, coal accounts
for more than fifty percent of electricity.
Coal is primarily used as a solid fuel to produce heat through combustion. World
coal consumption is about 5,800 million short tons annually of which about 75
percent is used for electricity generation. China and India uses about 1,700
million tons annually, forecasted to exceed 3,000 million tons in 2025. Coal is
the fastest growing energy source in the world, with coal use increasing by 25
percent for the three year period ending in December 2004 (BP statistical Energy
Review June 2005).
When coal is used in electricity generation, it is generally pulverized and then
burned. The heat produced is used to create steam, which is then used to spin
turbines to turn generator and produce electricity. About 40 percent of world’s
current electricity production is powered by coal, and the total known deposits
recoverable by current technologies are sufficient for 300 years’ use at current
rates.
Coal Gasification
High prices of Oil and Natural Gas are leading to increased interest in “Btu
Conversion” technologies such as Coal Gasification, Methanation and
Liquefaction. In the past coal was converted to make coal gas, which was piped
to customers to burn for illumination, heating and cooking. Natural gas has
almost knocked out coal gas. South Africa still uses gasification of coal for
much of its petrochemical needs. Gasification generally burns hotter and cleaner
than conventional coal, can spin a more efficient gas turbine rather than a
steam turbine and makes carbon dioxide for sequestration much easier.
Coal liquefaction
Coal can also be converted into liquid fuels like gasoline or diesel by several
different processes. The Fischer-Tropsch process of indirect synthesis of liquid
hydrocarbons was first used by Nazi Germany, and for many years by Sasol in
South Africa – because those regimes were politically isolated and unable to
purchase crude from the open market. Coal would be gasified to make Syngas (a
balanced purified mixture of Co and H2 gas) and the Syngas condensed using
Fischer –Tropsch catalyst to make light hydrocarbons, which are further
processed into gasoline via the Mobil-M-gas process. A direct liquefaction
process Bergius process (liquefaction by hydrogenation) is also available but
has not been used outside Germany, where the process was developed during World
War 1 and world war 2. SASOL in South Africa has also experimented with direct
hydrogenation. Several other processes have been developed, among these being
the SRc-1, and SRC-2 (Solvent Refined Coal) processes developed by Gulf oil.
Another process to manufacture of liquid hydrocarbon from coal is Low
Temperature Carbonization (LTC coal liquefaction is one of the backstop
technologies that limit escalation of oil prices. Among commercially mature
technologies, advantage for indirect coal liquefaction over direct coal
liquefaction are reported by Williams and Larson. Estimates are reported for
sites in China where break-even cost for coal liquefaction may be in the range
between 25 to 35 US$/barrel of oil.
Cooking and Use of Coke
Coke is a solid carbonaceous residue derived from low-ash, low sulfur bituminous
coal from which the volatile constituents are driven off by baking in an oven
without Oxygen at temperatures as high as 1000oc (200o/f) so that the fixed
carbon and residual ash are fused together. Coke is used as a fuel and as
reducing agent in smelting iron ore in a blast furnace. Coke from coal is gray,
hard and porous and has a heating value of 24.8 million Btu/to (29.6 Mj/kg). By
products of this conversion of coal to cake include coal tar, ammonia, light
oils and coal gas.
Underground Coal Gasification
Underground coal gasification (UCG) is the in situ gasification of coal in the
seam. It is achieved by injecting oxidants, gasifying the coal and bringing the
product gas to surface through boreholes drilled from the surface. The gas is
used for power generation, industrial heating or as chemical feedstock. UCG or
CBM has developed as large scale gas production process in the former Soviet
Union and trial schemes have been evaluated in many countries including United
States, Chinas Australia and the U.K.
World Coal Reserves
As of 2003 it was estimated that one hexagram (1x10 15 kg) of total coal
reserves economically accessible using current mining technology. The energy
value of all the worlds coal is well over 100,000 quadrillion Btu (100
zettajoules). There probably has enough coal to last for 300 years, considering
no rise in world population and no in creased use of coal to attempt to
compensate for depletion of natural gas and petroleum.
Methods of Extraction
The method of extraction of coal from coal seams depends on the depth and
quality of the seams, and also the geology and environmental factors of the area
being mined. If the coal seams are near the surface the coal is extracted by one
of the two methods. One method, strip-mining, exposes the coal by the
advancement of an open pit or strip. As the coal is exposed and extracted, the
overburden from the still covered coal fills the former pit, and strip
progresses most open cast mines in the USA extract bituminous coal. In South
Wales open casting for steam coal and anthracite is the preferred option.
Most modern coal in British Colombia, Canada, and Queensland, Australia are open
pit mines. It is preferred for lesser cost, safer mining and much greater
recovery. It is more appropriate for faulted coal seams, which are twisted and
bent. It makes underground mining very difficult. Underground tunnels which has
to follow crooked seams can be dangerous. It will require lot of money and time
still recovery will be minimum In open pit mines, employees do not have to work
in small dangerous areas where there could be harmful or explosive gases. There
is also no danger of cave ins in open-pit mines.
However, most coal seams are too deep underground for open cast mining. In deep
mining the Roof and Pillar method progresses along the Mammoth coal vein seam,
while pillars and timber are left standing to support the coal mine roof. This
is a dangerous method of operation in deep mining and is dubbed the term
“Robbing the Pillars” This method of mining was in use in the United States and
caused many fatalities in the early history of coal mining.
Long wall mining method is conducted along the seam. With the use of self
advancing hydraulic roof supports known as “Chocks” or “shields” These supports
are placed in a line (up to 400 meters long) known as “long wall” and as coal is
removed from in front of the long wall, the support are advance. As the long
wall advances, the cavity created behind the long wall known as the “goaf” caves
in, Long wall mining is the principal method in case of Underground mining in
Australia.
Finally, High Wall Mining is a form of coal mining in which a continuous miner
is controlled from outside the mine, and is guided along the seam straight back
drilling holes in excess of 500 feet. A high wall is the unexcavated face of
exposed overburden and coal in a surface mine. As the coal is sheered off the
face of the seam, it falls below to a conveyor belt that transports the coal to
the surface.
Other methods of mining include High Wall Auger Mining generally applied in an
open cast mine, once is becomes uneconomical.
Dangers to Miners
Coal mining historically, has been a very dangerous activity. Open cut hazards
are principally slope failure, underground mining roof collapse and gas
explosions. Most of these risks can be greatly reduced in modern mines, and
multiple fatality incidents are now rare in the developed world. Improvements in
mining methods (i. e long wall mining), gas drainage safety lamps, and
ventilation have reduced many of these risks. In less developed countries,
however, thousands still die in coal mines.
China in particular is the world leader in coal mining related deaths, with
official estimates of around 6,000 in 2004. Unofficial estimates place the
figure much higher, at around 20,000 deaths. China is also the world leader in
coal production and consumption. Chronic lung diseases, such as pneumoconiosis
are common to miners, causing a reduced life expectancy for those in the
occupation. Black damp, a mixture of carbon dioxide and nitrogen in a mine can
cause suffocation.
Types of Coal
As geological processes apply pressure to peat over the time it is transformed
successively into:
Lignite: also referred as brown coal, is the lowest category of coal and used
almost exclusively as fuel for steam electric power generation. Jet is a compact
form of lignite that is sometimes polished and has been used as an ornamental
stone since Iron Age.
• Sub-bituminous coal: whose properties range from those of lignite to those of
bituminous coal and are used primarily as fuel for steam electric power
generation.
• Bituminous Coal: A dense coal, usually black sometimes dark brow, often with
well defined bands of bright and dull material, used primarily as fuel in steam
electric power generation, with used for heat and power application in
manufacturing and to make coke.
• Anthracite: the highest category, used primarily for residential and
commercial space heating.
The author has thought it prudent to deliberate on the basics of coal for
brainstorming of all stakeholders to come to an appropriate conclusion on our
coal policy.
Anatomy of Draft Coal Policy
Vision statement of policy in its initial paragraphs have stated that 1400Mt of
mine able coal reserves in the north western part of Bangladesh represents
approximately 37Tcf of natural gas in terms of heating value.
Comments
This statement is premature and not too professional. . Extensive study is
required about the composition, mining methods, useable options to make such a
qualified statement. On the other hand it tends to give wrong signal to policy
makers. Such a sweeping statement in the introductory paragraph is not very
intelligent given the fact that the committee obviously did not many mining or
energy experts who have extensive hand on experience of coal mining.
Regarding mining technology opencast is definitely the answer as our mining
areas have poor roof supports, big aquifer and we need to extract the maximum
amount of coal. Underground mining is risky and can recover very little at a
very high cost. Bangladesh must have learnt a bitter lesson from Chinese
adventurism at Barapukuria.
The author aggress with the observation of the draft policy in that coal assets
under the ground have much higher economic value to ensure our longer term
energy security compared to the resettlement expenses of local population, the
price of crops, impact on environments. Modern opencast technologies ensure
simultaneous refilling of open pit as the mining progress with the over burden
of already recovered coal pits. Only the final section may be ultimately turned
into a sweet water lake.
The export and domestic use ratio has to be decided upon mutual discussion and
agreement with mine developers on case to case basis.. In free open market, the
market forces will decide options. Policy can have a general pricing formula for
coal in case of domestic use and export. But it won’t be justified to cap
production rate or control export. Otherwise potential investors won’t risk
their huge investment in a regulated domain.
When the investment risk, marketing risk, exploration and development risks
would be shouldered exclusively by private sector developers what role the
dormant Bureau of Mineral Development would play. Rather the competent
accomplished mining experts of BMD may be included in BERC after amending the
Act and incorporating the provisions for regulating coal mining as well as its
trading. Creating too many cooks will end up in fiasco. The author agrees that
GSB should of a development fund for human resource development of GSB. It
should be strengthened with visionary and dynamic professionals.
Bangladesh must not permit any further natural gas based large power plants
after 2010. That will give incentive to coal mine developers to set up coal
based power plants in the vicinity of the mines. Coal for power generation will
relieve the over stressed and fund constrained natural gas sector from
subsidized gas supply to power plants. However, if the coal mine developers set
up power plants then the transmission facility from west to east will require
substantial up-gradation. Coal price for power generation and price of power
from coal based plants should not be subsidized but regulated by independent
regulator here in this case off course Bangladesh Energy Regulatory Commission (BERC).
The BERC Act 2003 should be amended to cover coal mining leasing issues, coal
pricing etc. Another new body in a human resource restricted country will only
create another white elephant.
Vision Statements in the Coal Sector
The author strongly supports the statements of draft policy that North-western
Bangladesh may be declared as coal zone through which it can become power house
for Bangladesh. It will definitely have a long term all round impact on the
entire region from Foreign Direct Investment (FDI) is the only way out for coal
mining as all other initiatives exercised so far brought little tangible
benefits. Suppliers credit utilized in Barapukuria has become a pair in the neck
for poor Bangladesh. It has met several disasters and may encounter few more.
Flooding, poisonous gas and now running the mine mouth or mine top power plant
may have to use imported coal. Mine developers would be made to take appropriate
actions to relocate and rehabilitate affected landowners and restore income
generation. New employment opportunity, Satellite Township with modern amenities
of life can change the world for the downtrodden neglected population of the
area. Entire region from Dinajpur to Khulna would become new economic hub. Monga
prone Rangpur people may have round the year work opportunity. Mongla Port can
become lively and vibrant.
Potential investors of such huge dimension must be given due incentives and
governments must demonstrate strong political will and commitment to overcome
criticism of narrow vision theoreticians who always oppose any development
initiatives to create storm over the cup of tea.
Open cast mining would cause relocation, rehabilitation reemployment of affected
people. Considering the huge potential of high quality of expensive coal which
can not only ensure our energy security but also earn huge foreign exchange we
have to act prudently and rationally.
Considering the emerging coal mining activities and lack of exposure, experience
and expertise Bangladesh must without delay introduce Mining Engineering in BUET
and other Engineering Universities. Potential investor must also recruit
Bangladeshi fresher (Mechanical, Electrical, Chemical, Civil Engineers,
Geologist) and train them abroad in mining institute and active mines to create
technical base.
Whether or not Jamalganj coal mine is suitable for Coal Bed Methane (CBM) has to
be assessed on in depth analysis and review of coal composition, recovery
potential and overall economics. These days coal gasification, coal liquefaction
technologies have over ridden CBM. Jamalganj the author apprehends may not be an
ideal candidate for CBM.
Developing peat potentials may be given serious thoughts. The author agrees with
the most of the high lights of 20years coal sector goal which are:
I. To undertake exploration activities in unexplored frontiers and also in
identified coal basins to discover new coal fields.
II. To develop coal deposits in a planned manner to maximize coal recovery
maintaining best engineering and health, safety and environmental practices.
III. To regulate yearly production of coal to 30Mtpa however is neither
consistent nor prudent in the context of the vision. Why should FDI flow in a
restricted market? Potential investors won’t risk capital if they don’t get
economic return within envisioned period. We should let it be decided by BERC on
case to case basis, always ensuring that developers are committed to ensuring
energy security of Bangladesh prior to export.
IV. To attract private investors both for exploration and exploitation. The iii
and iv contradicts. If we cap annual production to bare 30Mtpa competent foreign
investors will fast loose focus.
V. To minimize coal mine related environmental and safety hazards and to ensure
compliance of mitigation measure and reclamation procedures.
This must be meticulously observed, monitored and regulated by the coal HSE
staffs of BERC. Safety and environment should not be compromised like the
ongoing Barapukuria coal mine.
Other goals have already been commented upon. Part B of the drafts policy
defines terms, section-3 elaborates Energy Security by coal development which
has very little to argue other than regulation of coal production and export.
The way the regulation of coal sector production has been articulated it will
give wrong signal to potential investors. In dynamic domain capping production
for maintaining a 50year reserve to production ratio may end up in same fiasco
as of natural gas. Not the Bureau of Mines but BERC after amendment of BERC Act
2003 should be the sole authority to issue mining license. BMD should be
absorbed in BERC.
The target of annual production will depend on economic feasibility of
individual mines, capacity of local market to absorb and also recovery of
investment of the investors. BERC may review it on case to case basis and ensure
to protection of resources of Bangladesh. The author agrees with the
Environmental aspects/ considerations enumerated in the draft policy.
Community participation, ground water management and aquifer structure, mine
water management, environment management plan, environment costs and environment
impact research have been correctly articulated in the drafts policy.
Land utilization and reclamation has also been dealt with properly. Private and
private sector investments to carry forward coal sector master plan have also
been correctly identified. Draft Policy also includes exploration options,
process of investor selection which requires intensive interaction among stake
holders. Report also includes other options of awards of mining which encompass
coal basin for captive mining possibly for Tata projects and projects of similar
dimensions. Peat blocks are an interesting option and can be explored. Coal Bed
Methane is still under research and development. Production sharing contracts
for our Coal sector may not be appropriate option. Bangladesh coal sector public
companies do not have credibility for any reputed international company to even
bother about joint venture. It has almost non existent technical and financial
capability. It has been also systematically destroyed by corrupt public sector
and local business syndicates.
Coal policy formulation is courageous initiative of EMRD of MOEMR. The committee
has done an excellent base policy. Extensive interaction of knowledgeable civil
society, academia, professional groups, potential investors, other stake holders
would further refine, update it and make it time tested and appropriate for
energy hungry Bangladesh. Emotions of non practicing environmentalist and
politically ill motivated so called intellectuals with negative mindset will
continue to oppose any and every development initiative. But government must
remain committed to its Millennium Development Goal, PRSP and Energy Security
vision without bothering for petty group interests. Draft coal policy is a noble
initiative and good stepping stone. |
