What is Coking Coal?

• About:
  • Also known as metallurgical coal, it is a naturally occurring sedimentary rock found within the earth’s crust.
  • A type of bituminous coal, it typically contains more carbon, less ash, and less moisture than thermal coal, which is used for electricity generation.
  • It is a vital raw material for steel production (constituting 42% of steel costs), making it indispensable for infrastructure and industrial growth.
• Application in steel production:
  • Coke/ metallurgical coke, which is created through the high-temperature carbonisation of coking coal, plays a crucial role in steelmaking.
  • Coke is used in blast furnaces to produce pig iron, serving as both a reducing agent for iron ore and structural support for the furnace charge.
• The largest producers of coking coal in the world: China (676 million tons in 2022-62%), Australia (169 million tons in 2022-15%), Russia (96 million tons in 2022-9%), USA (55 million tons-5%), and Canada (34 million tons-3%).
• Case of India:
  • Despite India’s vast reserves, reliance on imports remains at a staggering 85%.
  • For example, India’s coking coal imports for the first six months of the current fiscal (April – Sept) were at a six-year-high at 29.6 million tonnes (mt) with shipments from Russia witnessing a substantial rise of over 200% during this period.

Current Challenges in Domestic Production of Coking Coal:

• Inefficiency in coal washeries:
  • Public Sector Undertaking (PSU) washeries operate at less than 32% capacity, with washed coal yields of only 35–36%.
  • In contrast, private washeries achieve over 75% capacity utilisation and higher yields, showcasing the need for improved efficiency in PSU washeries.
• High import dependency: Integrated Steel Plants (ISPs) imported 58 MT of coking coal at an enormous cost of ₹1.5 lakh crore in FY 2023-24, despite significant domestic reserves.

Key Recommendations from the NITI Aayog Report:

• Recognising coking coal as a critical mineral:
  • This will align India with global practices such as in the European Union, which recognises coking coal as critical.
  • Designating it as critical can justify policy support to boost domestic production and ensure security for India's steel sector.
• Leveraging domestic reserves:
  • India holds 5.13 billion tonnes of prime coking coal and 16.5 billion tonnes of medium-quality reserves.
  • These resources should be fully utilised, considering the country’s Net Zero 2070 commitments and economic needs.
• Policy and structural changes:
  • Amending the Coal Bearing Areas (CBA) Act, 1957: To ensure that Special Purpose Vehicles (SPVs) under public-private partnership (PPP) arrangements retain operational rights, even after majority ownership shifts to the private sector.
  • Facilitating byproduct sales: The Ministry of Coal must enable joint ventures to sell byproducts (middling and tailings) from washeries, benefitting steel plants with lower coking coal expenses. 

What are Critical Minerals?

• Meaning:
  • A mineral is critical when the risk of supply shortage and associated impact on the economy is (relatively) higher than other raw materials.
  • These (such as lithium, graphite, cobalt, titanium, and rare earth elements) form part of multiple strategic value chains, including
    • Clean technologies,
    • Information and communication technologies (including semiconductors) and
    • Advanced manufacturing inputs and materials.
• Identification of 30 critical minerals by the Indian Govt: This was done by the Ministry of Mines on the basis of a 3-stage assessment -
• In the first stage, a total of 69 elements/ minerals were identified on the basis of the strategies of various countries such as Australia, USA, Canada, UK, Japan and South Korea.
• In the second stage, an inter ministerial consultation was carried out with different ministries to identify minerals critical to their sectors.
• In the third stage, taking cognisance of the EU methodology (that considers two major factors - economic importance and supply risk), an empirical formula for evaluating minerals criticality was derived.
• • Based on this process, a total of 30 minerals were found to be most critical for India:

Conclusion: Boosting domestic coking coal production is critical for securing India’s energy and industrial future.
