Facts from India Coal Market Watch – August 2011
Domestic coal production target for 2011-12 is 554 mt
India adds 1660 MW generation capacity in July (all Thermal Power)
Indian plants exceed power generation target in July 2011
Coal India Ltd (CIL) reported a 64.06% rise in profit after tax (PAT) during the first quarter (April-June) of 2011-12
So far so good……………..
Facts from India Coal Market Watch Out! – August 2011
India’s coal import in 2011-12 likely at 137.03 mt
The import of coking coal through Paradip port on the eastern coast of India surged by almost 4,10,095 tons in July 2011 to 6,68,574 tons as compared to 2,58,479 tons in June 2011
Imports of PCI coal through Vizag port in July 2011 stood at 1,13,467 tons, which was higher by 86,764 tons than 26,703 tons imported in June 2011
The imports of Low Ash Metallurgical (LAM) coke through Paradip port in the month of July 2011 rose sharply to 60,590 tons compared with 6000 tons in June 2011
171 coal mining proposals involving 28,862 hectares of forest land are awaiting forestry clearance as on June 30, 2011
44 projects of Coal India Ltd (CIL) stuck under Comprehensive Environment Pollution India (CEPI) norms introduced by MoEF
Question?
Can the most efficient users of coal in India’s
Steel Sector help -
increase India’s Energy Self-Sufficiency,
meet it’s Climate Change Commitments,
and also save some Forests in the bargain?

Energy Efficiency measures
Process efficiency – sinter plant heat recovery, coal moisture control
Optimized energy use - pulverized coal injection, coke dry quenching and recovering waste heat
Fuel Shift
Substituting coke used in BF/BOF furnaces with fuel based on biomass (charcoal)
Replacing 10% of coke as the primary blast furnace tool
Technology Changes
Direct smelting remove need for coking plants Challenge – Issues with technologies need to be resolved
Scrap based steel making 1/3 energy required by standard blast furnace Challenge – if 10% of the total production moved to this system
70% of India’s steel would need to be recycled which involves a economic cost
Gas based direct reduced iron Challenge: Availability of gas to steel plants
Cogeneration – gas from the BOF/BF process is recovered, cleaned and used for power generation
Energy Self-Sufficiency and Indian Steel Sector
Coking coal prices at $225 a ton for the second quarter beginning July 2010 compared with $129 a ton level in 2009-10
Very high dependency on Australia for coking coal
Energy Self-Sufficiency: India would need 2.4 billion tonnes of steel/yr by 2030 which would assume India would need to import 40% of its coal needs
Learnings and Way Forward Best practice gap in terms of GHG Intensity of Production from Coal for
Cement Industry: increased from ratio of 13.4 to 15.7 in 3 years.
Best Practice Technology (BPT) replication achievable realistically using off-the-shelf technologies in India
BPT replication in Steel Industry alone can yield 36 million tons of coal saving and reduce India’s imports dramatically
BPT replication from merely this sector can help India achieve more than 100% of its GHG Emissions commitment to COP15 (reducing GHG intensity of the GDP by 20%-25% by 2020)
Thus, despite being a proactive environmental research and outreach body – not anti-coal as a fuel – but a rational promoter of the roadmap to do more with the lessening coal we have in India and globally.
Need of the hour – process optimisation technology sharing amongst the Steel Industry and active promotion and incentivisation of efficient users of coal and low-GHG intensity steel on platforms such as coaljunction and metaljunction.
