Coal India Unveils ₹69,346-Crore Diversification Push, Targets Gasification, Renewables and Critical Minerals – Indian PSU

Coal India Limited (CIL) is embarking on one of its most significant business diversification drives, expanding beyond conventional coal mining into coal-to-chemicals, thermal power, renewable energy, battery storage, critical minerals, advanced materials and technology-led research.

The state-owned coal major has structured its Business Development portfolio around five mutually reinforcing platforms — coal gasification and coal-to-chemicals; thermal power; renewable energy and storage; critical minerals and advanced materials; and diversified minerals, including iron ore. The strategy is aimed at creating new growth engines while supporting energy and mineral security, import substitution and indigenous technology development.

₹69,346 crore coal-to-chemicals portfolio

The biggest component of the diversification programme is coal gasification and coal-to-chemicals, with four major projects involving an estimated ₹69,346 crore.

The portfolio includes Talcher Fertilizers Ltd, with a 1.27 million tonne annual urea capacity and an estimated project cost of ₹19,062.22 crore; Bharat Coal Gasification & Chemicals Ltd, with 0.66 million tonne annual ammonium nitrate capacity and a project cost of ₹25,015.89 crore; Coal Gas India Ltd, targeting 633.6 million Nm³ of synthetic natural gas annually at an estimated cost of ₹13,052.81 crore; and the CIL-BPCL Chandrapur coal-to-SNG initiative, also targeting 633.6 million Nm³ annually at an estimated cost of ₹12,214.86 crore.

Coal gasification converts coal into synthesis gas, or syngas, which can then be used to manufacture products including synthetic natural gas, ammonia, urea, ammonium nitrate and methanol.

The strategy is particularly significant because it seeks to extract greater chemical value from coal rather than limiting its use to conventional combustion.

CIL enters large-scale power generation

CIL is also moving deeper into power generation.

The company and Damodar Valley Corporation are pursuing a 2×800 MW ultra-supercritical brownfield expansion at Chandrapura, through a proposed 50:50 joint venture. The project would add 1,600 MW of generation capacity to CIL’s broader business portfolio.

Renewable energy and battery storage

The diversification strategy also has a substantial renewable-energy component.

CIL has already commissioned approximately 550 MW of solar capacity and is pursuing utility-scale, captive and floating solar projects. The company is simultaneously entering grid-scale Battery Energy Storage Systems (BESS).

Its portfolio includes an 80 MW/320 MWh BESS programme in Odisha, spread across four locations with a four-hour storage duration. Capacity has been secured through SECI and the EPC tender has been issued.

The Ministry of Coal has set a broader target of 9.5 GW of renewable-energy capacity for CIL by 2029-30, as part of a combined 22.5 GW renewable target for CIL, NLCIL and SCCL.

Critical minerals become a new frontier

Perhaps the most strategically significant part of CIL’s diversification is its entry into critical minerals and advanced materials.

CIL is pursuing domestic opportunities involving graphite assets in Madhya Pradesh and Chhattisgarh, along with rare-earth-element and rare-metal opportunities in Andhra Pradesh and Maharashtra.

The company is looking beyond mining alone and examining the entire graphite value chain — from resource definition and beneficiation to purification, spheronisation, coating and downstream product development.

Such materials are critical to batteries, electric vehicles, renewable-energy systems, electronics, advanced manufacturing, aerospace and defence.

Underground coal gasification enters pilot phase

CIL is also testing a technology that could potentially unlock coal resources that are difficult or uneconomic to mine conventionally.

A phased Underground Coal Gasification (UCG) pilot is underway at the Kasta West Block of Eastern Coalfields Ltd. The technology converts deep-seated or otherwise unmineable coal into syngas underground.

However, the Ministry has made it clear that UCG has not yet demonstrated commercial viability globally. CIL is therefore following a phased approach, with wider replication dependent on operating data and commercial performance.

Technology becomes the backbone

CIL’s diversification strategy is not confined to acquiring assets. The company is simultaneously building a technology and R&D ecosystem around the new businesses.

The focus areas include adaptation of technologies to high-ash Indian coal, process optimisation, localisation of critical equipment, advanced process controls, digital twins, predictive maintenance and improved water, ash and emissions management.

Its 2026 R&D framework also gives greater emphasis to artificial intelligence, machine learning, IoT-based smart mining, clean coal technologies, waste-to-wealth, renewable energy, mineral processing and technology indigenisation.

CIL-supported Centres of Excellence include facilities at IIT Madras, IIT Hyderabad and IIT (ISM) Dhanbad, covering sustainable energy, clean coal, Mining 4.0, smart mines, automation and innovation.

Diversification with financial discipline

Importantly, CIL’s strategy does not envisage diversification at any cost.

The company says projects will be assessed for commercial sustainability and risk-adjusted returns, with stage-gate mechanisms, measurable outcomes, technology validation and risk management built into the decision-making process. Emerging technologies are expected to be replicated only after operating and commercial performance has been validated.

That approach will be particularly important for capital-intensive ventures such as coal gasification, BESS and advanced-material manufacturing, where technological and commercial risks can be materially different from conventional mining.

From coal miner to diversified energy and minerals company

CIL’s latest portfolio marks a significant broadening of its business architecture.

Coal will remain at the centre of the company’s operations, but the new strategy seeks to build additional businesses around coal conversion, power generation, renewables, energy storage, critical minerals, advanced materials and technology.

The immediate challenge will be execution — converting a large pipeline of projects and technology initiatives into commercially viable businesses.

If successfully executed, however, the diversification programme could give Coal India a substantially broader business footprint, with new revenue platforms extending well beyond the conventional coal-mining value chain.
