🔴 In News: Union Cabinet approves ₹37,500 crore Coal Gasification Scheme — one of India’s most significant energy policy decisions in recent years
⚡ Quick Answer — What is Coal Gasification?
Coal gasification is a thermo-chemical process that converts coal or lignite into syngas (synthesis gas) — a mixture of carbon monoxide (CO) and hydrogen (H₂) — under high temperature and pressure in the presence of oxygen and steam. Unlike direct combustion, it is a cleaner method of using coal. Syngas can produce power, fertilisers (urea, ammonia), chemicals (methanol, DME), liquid fuels, and hydrogen. India aims to gasify 100 million tonnes of coal by 2030. The Union Cabinet recently approved a ₹37,500 crore scheme to gasify approximately 75 million tonnes of coal and lignite, targeting investments of ₹2.5–3 lakh crore and 50,000 jobs.
What is Coal Gasification?
Coal gasification is a thermo-chemical process that converts coal or lignite into synthesis gas (syngas) — primarily a mixture of carbon monoxide (CO) and hydrogen (H₂). It is fundamentally different from burning coal directly (combustion), in that it converts coal into a gaseous form that can be used as a cleaner, more versatile industrial feedstock.
The key distinction from direct combustion is controlled conversion: rather than simply releasing energy as heat, gasification transforms the carbon-rich material into usable gas that can be further processed into chemicals, fuels, and electricity — with significantly lower direct emissions than coal burning.

How Does Coal Gasification Work?
The coal gasification process involves a series of chemical reactions under specific conditions. Coal or lignite is fed into a gasifier where it reacts with controlled quantities of oxygen (or air) and steam under high temperature (700–1,600°C) and elevated pressure. This breaks down the carbon-rich coal into its constituent gaseous elements.

Key Chemical Reactions in Gasification
| Reaction | Equation | Significance |
|---|---|---|
| Partial Oxidation | C + ½O₂ → CO | Main reaction generating carbon monoxide |
| Water Gas Reaction | C + H₂O → CO + H₂ | Steam reacts with carbon to produce syngas components |
| Water Gas Shift | CO + H₂O → CO₂ + H₂ | Increases hydrogen yield; used to adjust syngas composition |
| Methanation | CO + 3H₂ → CH₄ + H₂O | Converts syngas to synthetic natural gas (SNG) |
Key distinction for UPSC: Coal Gasification ≠ Coal Combustion. Combustion burns coal directly to produce heat/electricity with high emissions. Gasification converts coal into syngas — a versatile feedstock with significantly fewer direct emissions — which can then be used for power, chemicals, or fuels. This makes gasification a cleaner way to use coal, though still carbon-intensive compared to renewables.
Applications of Syngas — What Can It Produce?
Syngas (CO + H₂) is one of the most versatile industrial feedstocks in the world. It can be converted into a wide range of end products through downstream chemical processes, making it a strategic raw material for multiple industries.
| Product Category | Specific Products | Strategic Relevance to India |
|---|---|---|
| Power & Energy | Electricity, Synthetic Natural Gas (SNG) | Reduces LNG imports; dispatchable baseload power |
| Fertilisers | Urea, Ammonia, Ammonium Nitrate | India imports ~₹50,000 Cr+ of fertilisers annually — gasification can substitute |
| Chemicals | Methanol, Dimethyl Ether (DME) | Methanol as fuel additive; DME as LPG substitute |
| Liquid Fuels | Synthetic petrol, diesel (via Fischer-Tropsch) | Reduces crude oil import dependence |
| Hydrogen | Industrial hydrogen (Blue Hydrogen) | Foundation for India’s hydrogen economy; feedstock for refineries and steel |
UPSC Note — Blue Hydrogen Connection: When coal gasification is combined with Carbon Capture and Storage (CCS), the hydrogen produced is classified as Blue Hydrogen — a lower-emission alternative to hydrogen produced from fossil fuels without CCS (Grey Hydrogen). This connects coal gasification to India’s National Green Hydrogen Mission and broader climate policy debates.
Why Coal Gasification is Strategically Important for India
India’s decision to invest heavily in coal gasification is not arbitrary — it is grounded in a convergence of energy security concerns, import substitution imperatives, and industrial policy goals.
- 🔋 Energy Security: India holds approximately 401 billion tonnes of coal and 47 billion tonnes of lignite — among the world’s largest. Coal contributes more than 55% of India’s energy mix. Gasifying this abundant domestic resource reduces dependence on imported LNG, coking coal, and fossil fuel-based chemicals.
- 💰 Import Substitution: India’s import bill for LNG, urea, ammonium nitrate, ammonia, coking coal, methanol, and DME stood at approximately ₹2.77 lakh crore in FY2025. Coal gasification can domestically produce all of these, saving foreign exchange and reducing current account pressure.
- 🌍 Geopolitical Resilience: The ongoing West Asia conflict has demonstrated the vulnerability of global supply chains for LNG and petrochemicals. Domestic coal gasification insulates India from price volatility and supply disruptions caused by geopolitical events.
- 🌱 Cleaner Coal Utilisation: Gasification produces significantly fewer particulate emissions and sulphur dioxide compared to direct coal combustion. It also enables carbon capture more efficiently, offering a potential pathway to lower-emissions use of India’s vast coal reserves during the energy transition.
- 🏭 Industrial Diversification: Coal-bearing regions (Jharkhand, Odisha, Chhattisgarh, Madhya Pradesh) currently have limited economic activity beyond coal extraction. Gasification-based industries can transform these regions into chemical and energy production hubs.
- 🇮🇳 Atmanirbhar Bharat Alignment: Coal gasification directly supports the Atmanirbhar Bharat initiative by substituting imports with domestically produced syngas derivatives, strengthening industrial self-reliance in chemicals, fertilisers, and fuels.

Financial Incentives & Caps — Scheme Architecture
To ensure equitable distribution of incentives and prevent concentration of benefits, the scheme has established clear caps at three levels:
₹5,000 Cr
Maximum incentive per single project
₹9,000 Cr
Maximum per single product category (excl. SNG and Urea)
₹12,000 Cr
Maximum per single entity or group across all projects
Additionality Principle: The incentives under this scheme are additional to — and do not restrict access to — other Central or State Government schemes, including those under the commercial coal mining regime. This stacking principle is designed to maximise the attractiveness of investment in coal gasification projects.
30-Year Coal Linkage — Structural Reform
A critical accompanying structural reform is the extension of coal linkage tenure to 30 years under the “Production of Syngas leading to Coal Gasification” sub-sector in the Non-Regulated Sector (NRS) linkage auction framework. This addresses one of the most significant investment barriers in coal-based industries — long-term feedstock security. Without a guaranteed coal supply over a 30-year horizon, private investors cannot justify the capital expenditure required for gasification plants. This reform provides the policy certainty necessary to unlock large-scale private investment.
Strategic & Economic Benefits of the Coal Gasification Scheme
Import Substitution — The Economic Case
India’s import dependency in key chemical and fuel categories represents a major structural vulnerability. The scheme directly targets substitution of the following imports:
| Import Category | Current Import Scenario | How Coal Gasification Helps |
|---|---|---|
| LNG (Liquefied Natural Gas) | India is one of the world’s largest LNG importers; exposed to global price spikes | Synthetic Natural Gas (SNG) from coal gasification substitutes LNG domestically |
| Urea (Fertiliser) | India imports significant urea volumes; fully subsidised by government | Ammonia/urea from syngas reduces import bill and fertiliser subsidy burden |
| Ammonia | Raw material for multiple industries; import-dependent | Syngas directly produces ammonia for fertilisers and industrial use |
| Methanol | India has a Methanol Economy Programme but limited domestic supply | Methanol produced from syngas supports fuel blending and chemical industries |
| Coking Coal | India imports ~50 MT of coking coal annually for the steel sector | Syngas-based steelmaking (DRI process) can reduce coking coal dependence |
| Dimethyl Ether (DME) | Emerging LPG substitute; limited domestic supply | DME from syngas as a cooking fuel for rural and industrial use |
India’s combined import bill for LNG, urea, ammonium nitrate, ammonia, coking coal, methanol, and DME stood at approximately ₹2.77 lakh crore in FY2025. The scheme targets significant reduction in this import exposure over a 10–15 year horizon.
Geopolitical Context: The ongoing West Asia conflict has repeatedly disrupted global LNG and petrochemical supply chains, causing price spikes and supply shortages. For India — heavily dependent on these imports — the vulnerability is significant. Coal gasification using domestic reserves directly addresses this geopolitical supply chain risk, a theme that connects to GS Paper II (International Relations) and GS Paper III (Energy Security).

Frequently Asked Questions — Coal Gasification UPSC
What is coal gasification?▾
Coal gasification is a thermo-chemical process that converts coal or lignite into synthesis gas (syngas) — a mixture primarily composed of carbon monoxide (CO) and hydrogen (H₂) — by reacting it with oxygen and steam under high temperature and pressure. Unlike direct combustion (which burns coal to produce heat), gasification converts coal into a versatile gaseous feedstock that can be used to produce power, fertilisers, chemicals, liquid fuels, and hydrogen. It is considered a cleaner method of utilising coal compared to direct combustion.
What is syngas and what can it be used for?▾
Syngas (synthesis gas) is a mixture of carbon monoxide (CO) and hydrogen (H₂) produced from coal gasification. It is an extremely versatile industrial feedstock that can be used to produce: (1) Power and Synthetic Natural Gas (SNG); (2) Fertilisers — urea, ammonia, ammonium nitrate; (3) Chemicals — methanol, dimethyl ether (DME); (4) Liquid fuels through Fischer-Tropsch synthesis; and (5) Hydrogen — for industrial use and as the foundation for Blue Hydrogen (when combined with Carbon Capture and Storage). This versatility is a key reason for India’s strategic interest in coal gasification.
What is India’s coal gasification target by 2030?▾
India has set a target to gasify 100 million tonnes of coal by 2030. The recently approved Cabinet scheme — “Scheme for Promotion of New Surface Coal/Lignite Gasification Projects” — directly contributes to this target by supporting gasification of approximately 75 million tonnes of coal and lignite across 25 projects, with a government outlay of ₹37,500 crore to catalyse private investment of ₹2.5–3 lakh crore.
What are the key features of India’s new Coal Gasification Scheme 2025?▾
The Union Cabinet-approved Coal Gasification Scheme 2025 has the following key features: Total outlay of ₹37,500 crore; target of 75 million tonnes of coal/lignite gasification; financial incentive of up to 20% of plant and machinery costs (disbursed in 4 milestone-linked instalments); project selection through competitive bidding; incentive caps of ₹5,000 crore per project, ₹9,000 crore per product category, and ₹12,000 crore per entity/group; a structural reform extending coal linkage tenure to 30 years; expected private investment of ₹2.5–3 lakh crore; 50,000 jobs; and ₹6,300 crore in annual coal revenue.
How is coal gasification different from coal combustion?▾
Coal combustion burns coal directly in the presence of air/oxygen to produce heat and electricity, generating large amounts of CO₂, sulphur dioxide (SO₂), nitrogen oxides (NOx), and particulate matter. Coal gasification, by contrast, converts coal into syngas through a controlled chemical reaction with limited oxygen and steam — it does not burn the coal directly. Gasification produces fewer direct particulate emissions and sulphur dioxide; the syngas can be cleaned before use; and if Carbon Capture and Storage (CCS) is added, it can produce Blue Hydrogen with significantly reduced net CO₂ emissions. Gasification also produces a versatile feedstock (syngas) rather than just heat.
Why is coal gasification important for India’s energy security?▾
Coal gasification is important for India’s energy security for several reasons: India has massive domestic coal reserves (401 billion tonnes of coal + 47 billion tonnes of lignite) but imports ₹2.77 lakh crore worth of LNG, urea, ammonia, methanol, coking coal, and DME annually. Coal gasification can substitute these imports with domestically produced syngas derivatives, reducing foreign exchange outflow and insulating India from global price volatility. The ongoing West Asia conflict has highlighted how geopolitical events disrupt India’s energy supply chains. With domestic coal, India controls the resource, the supply chain, and the pricing — a fundamental shift in energy security.
What are the challenges of coal gasification in India?▾
The key challenges of coal gasification in India are: (1) Carbon emissions — gasification is still a fossil fuel process; without Carbon Capture and Storage (CCS), it generates significant CO₂, creating tension with India’s climate commitments; (2) Water intensity — gasification requires large volumes of water/steam, problematic in water-stressed coal-bearing regions; (3) High capital cost — large upfront investment requirements with long gestation periods; (4) Technology dependence — India lacks mature indigenous gasification technology and may need to import equipment; (5) Economic viability — dependent on import price of alternatives; cheaper global LNG or urea prices could undermine the economic case for domestic gasification.
How is coal gasification connected to the Methanol Economy and Blue Hydrogen?▾
Coal gasification connects to two of India’s major industrial policy initiatives: (1) Methanol Economy — India has a national programme to blend methanol in petrol and use it as a cooking fuel substitute. Methanol is produced from syngas, making coal gasification a key feedstock source for India’s methanol ambitions. (2) Blue Hydrogen — when the hydrogen component of syngas is separated and the CO₂ from the process is captured using Carbon Capture and Storage (CCS), the result is “Blue Hydrogen” — a lower-emission form of hydrogen. This connects coal gasification to India’s National Green Hydrogen Mission and the broader global hydrogen economy debate.
