The Union Cabinet’s approval of a ₹37,500 crore scheme to promote surface coal and lignite gasification — explicitly citing the West Asia (Strait of Hormuz) crisis as part of its rationale and targeting 100 million tonnes of annual coal gasification capacity by 2030 — marks a significant strategic pivot in India’s energy security architecture. This development, discussed extensively in a Hindu editorial by Dr. R.A. Mashelkar, former Director General of the Council of Scientific and Industrial Research (CSIR), frames the recent Hormuz disruption as a structural lesson: while India’s refining sector demonstrated remarkable resilience by diversifying crude oil sourcing during the crisis, its Liquefied Petroleum Gas (LPG) supply chain remains dangerously concentrated among a handful of Gulf and Atlantic Basin producers.
This topic sits squarely at the intersection of energy security, environmental policy, industrial strategy, and technological self-reliance — themes of central importance to India’s developmental trajectory. As India targets net-zero emissions by 2070 and energy self-reliance by 2047 (as outlined in policy briefs discussed elsewhere in this newspaper), the coal gasification push represents a fascinating policy tension: leveraging India’s most abundant domestic fossil fuel resource (coal) to reduce import dependence on a cleaner but externally-sourced fuel (LPG), even as the country simultaneously pursues decarbonisation goals.

For UPSC and SSC aspirants, this topic offers rich material spanning energy economics, technological innovation policy, environmental trade-offs, and India’s institutional response to geopolitical shocks — precisely the kind of multi-dimensional theme that UPSC Mains GS Paper III frequently tests.
Background and Context
Five Important Key Points
- The Union Cabinet has approved a ₹37,500 crore scheme to promote surface coal and lignite gasification, targeting 100 million tonnes of annual coal gasification capacity by 2030, explicitly motivated by the Strait of Hormuz supply disruption.
- India’s LPG import infrastructure had roughly doubled over the preceding decade, but during the Hormuz closure, the bottleneck was refining capacity rather than import terminals, prompting a five-day surge in domestic LPG production from 35,000 to 54,000 tonnes per day under the LPG control order.
- The Bureau of Indian Standards has approved blending up to 20% Dimethyl Ether (DME) — a coal-derived, clean-burning gas — with LPG, with industry estimates suggesting a 20% blend could displace 6.3 million tonnes of LPG imports annually, saving nearly ₹34,000 crore in foreign exchange.
- The scheme provides incentives of up to 20% of plant and machinery costs, separate from the DME blending ratio incentive, and extends coal linkage tenure to 30 years to provide long-term capital certainty for capital-intensive gasification projects.
- The core technology for converting methanol into DME was developed years earlier at CSIR’s National Chemical Laboratory, illustrating how sustained public investment in scientific research can convert into strategic national assets during unexpected crises.
Understanding Coal Gasification and DME as an LPG Substitute
Coal gasification is a chemical process that converts coal into syngas (a mixture of carbon monoxide and hydrogen), which can subsequently be converted into various downstream chemical products, including methanol and Dimethyl Ether (DME). DME is chemically similar enough to LPG that it can be blended directly into existing LPG cylinders and distribution infrastructure without requiring new pipelines or distribution networks — a critical practical advantage that dramatically lowers the implementation barrier compared to entirely new energy carriers like hydrogen, which require dedicated infrastructure.
Given that India possesses among the world’s largest coal reserves — concentrated substantially in states like Jharkhand, Odisha, Chhattisgarh, West Bengal, and parts of Bihar’s coal-belt-adjacent regions — leveraging domestic coal to produce a clean-burning, LPG-compatible fuel represents a rare instance where India’s most criticised domestic resource (coal, associated with pollution and climate concerns) can be repurposed to reduce a different, more geopolitically vulnerable, import dependence.
The Refinery Flexibility Precedent
Dr. Mashelkar’s editorial draws an important analytical distinction between two forms of energy resilience demonstrated during the Hormuz crisis: crude oil resilience achieved through refinery flexibility (the ability to process crude from diverse geographies including the Americas, West Africa, and Russia), versus LPG vulnerability, which persisted because the LPG molecule itself is geographically concentrated in sourcing regardless of refining capability. This distinction is crucial: India’s refining sector’s success in adapting crude sourcing from 55% to 70% non-Hormuz supply within weeks demonstrated that engineering flexibility built through two decades of sustained investment, workforce training, and process innovation can absorb sudden geopolitical shocks. However, this flexibility model does not automatically extend to LPG, since the molecule cannot be “engineered” from 40 different countries the way crude oil processing capability can be diversified — necessitating a fundamentally different solution: domestic production of a substitute molecule (DME) rather than merely diversifying import sourcing.
Economic and Fiscal Dimensions
The financial case for coal gasification is compelling on paper: potential annual foreign exchange savings of nearly ₹34,000 crore from a 20% DME-LPG blend, set against a ₹37,500 crore capital incentive scheme — suggesting the investment could pay for itself within roughly 18 months of full-scale implementation, assuming import substitution targets are met. However, the scheme’s success depends critically on execution capacity, given that India’s coal has historically had higher ash content than coal used in comparable coal-to-chemicals industries internationally (notably China’s dominant coal-to-chemicals sector), requiring further technological adaptation to achieve commercially viable gasification at scale.
Environmental and Climate Policy Tensions
This coal-based strategy sits in evident tension with India’s broader decarbonisation commitments, including its Nationally Determined Contributions (NDCs) under the Paris Agreement and its 2070 net-zero target. Critics may reasonably question whether incentivising coal gasification — even as a transitional bridge fuel strategy — risks entrenching coal-dependent infrastructure and capital investment that could become stranded assets as India accelerates renewable energy deployment. Proponents counter that DME-blended LPG substitutes for imported LPG rather than expanding overall fossil fuel consumption, and that the alternative — continued deep dependence on imported LPG from a handful of geopolitically volatile Gulf suppliers — carries its own strategic and economic risks that domestic coal gasification can mitigate during the transition period.
From Innovation to Execution: Institutional Lessons
A noteworthy institutional lesson from this episode is the speed with which India’s Centre for High Technology, under the Ministry of Petroleum and Natural Gas, approved scaling up an indigenous CSIR-developed DME pilot technology during the crisis — demonstrating that investments in foundational scientific research made years earlier can convert into strategic national assets when unexpected crises create urgent policy windows. This underscores a broader lesson for India’s innovation ecosystem: sustained public investment in research institutions like CSIR’s National Chemical Laboratory, even without immediate commercial application, builds latent national capability that can be rapidly mobilised when circumstances demand.
Way Forward
To fully realise this strategic opportunity, India must address the technical challenge of India’s higher-ash coal through continued research investment in gasification process optimisation. The government should also establish clear, time-bound targets and transparent monitoring mechanisms to track progress toward the 100 million tonnes annual gasification target by 2030, ensuring the scheme does not become another underutilised industrial policy instrument. Coordination between the coal, petroleum, and environment ministries will be essential to ensure gasification expansion aligns with broader emissions and environmental commitments, potentially incorporating carbon capture, utilisation, and storage (CCUS) technologies to mitigate the carbon footprint of coal-based DME production. Finally, sustained investment in indigenous research capability — following the CSIR-NCL model — should be scaled across other strategic technology domains to build similar crisis-resilience in other critical import-dependent sectors.
