| Term | Meaning |
|---|---|
| Coal Gasification | Thermo-chemical conversion of solid coal into gaseous synthesis gas (Syngas) through controlled partial oxidation with oxygen/air and steam at high temperature & pressure |
| Syngas | Synthesis Gas — primary output; mixture of CO + H₂ + CO₂ + CH₄ + H₂O vapour |
| Gasifier | High-temperature, high-pressure reactor vessel where gasification reactions occur |
| Partial Oxidation | Coal is NOT fully combusted; oxygen is limited → gasification, not burning |
| Autothermal | Coal heated by its own exothermic reactions within the gasifier |
| Allothermal | External heat source used to heat coal for gasification |
| Type | Description | Key Feature |
|---|---|---|
| Surface Coal Gasification (SCG) | Coal mined, brought to surface & gasified in a reactor | Conventional; more control; high capital cost |
| Underground Coal Gasification (UCG) | Coal converted in-situ within the seam; syngas extracted via wells | No surface mining; accesses deep/unmineable coal; lower capex |
| IGCC | Integrated Gasification Combined Cycle — syngas powers gas turbine + steam turbine | Higher power efficiency; cleaner power generation |
| Gasifier | Coal Type | Notable Feature |
|---|---|---|
| Fixed Bed (Moving Bed) | Lumpy coal; low ash melting | Simplest design; Lurgi/Sasol use this |
| Fluidized Bed | Low-rank, high-ash coal (suits India) | Invented 1922 by Winkler (BASF); uniform temperature; good for high ash |
| Entrained Flow | Pulverized coal slurry | Highest temp; cleanest syngas; Shell, Texaco designs; large-scale |
| Reaction Name | Equation | Type |
|---|---|---|
| Combustion (partial) | C + O₂ → CO₂; 2C + O₂ → 2CO | Exothermic; provides heat |
| Water-Gas Reaction | C + H₂O → CO + H₂ | Endothermic; primary syngas producer |
| Boudouard Reaction | C + CO₂ → 2CO | Endothermic; uses CO₂ |
| Methanation | CO + 3H₂ → CH₄ + H₂O | Produces SNG (Synthetic Natural Gas) |
| Water-Gas Shift | CO + H₂O → CO₂ + H₂ | Adjusts H₂:CO ratio for downstream use |
| Component | Symbol | Approx. Share |
|---|---|---|
| Carbon Monoxide | CO | 30–60% |
| Hydrogen | H₂ | 25–40% |
| Carbon Dioxide | CO₂ | 5–15% |
| Methane | CH₄ | 1–10% |
| Water Vapour | H₂O | Variable |
Indian coal has a characteristically high ash content of 30–45%, which is the single biggest technical challenge for domestic gasification — most global gasification technologies are designed for low-ash coal.
Coal Gasification ≠ Coal Combustion. In gasification, coal is not burned — it undergoes partial oxidation to produce syngas. Pollutants (SO₂, NOₓ) are captured before energy use, unlike in combustion where they are released post-burning. UPSC often tests this distinction.

| Parameter | UCG | SCG |
|---|---|---|
| Location of gasification | In-situ within coal seam (underground) | Surface reactor after mining |
| Mining required? | No — eliminates conventional mining | Yes — coal mined first |
| Coal seam access | Deep, thin, unmineable seams | Near-surface, mineable seams |
| Process | Inject oxidants (O₂/air/steam) → syngas rises through wells | Coal in gasifier reactor; controlled environment |
| Capital Cost | Lower (no mining infrastructure) | Higher |

| Step | Process |
|---|---|
| 1. Gasification | Coal + O₂ + Steam → Syngas (in gasifier) |
| 2. Gas Cleanup | Remove sulfur (H₂S), particulates, mercury from raw syngas |
| 3. Gas Turbine | Cleaned syngas combusted in gas turbine → electricity (primary use) |
| 4. Heat Recovery | Exhaust heat from gas turbine generates steam |
| 5. Steam Turbine | Steam drives steam turbine → additional electricity (combined cycle) |
IGCC efficiency advantage: Uses coal gases twice — first in gas turbine, then steam from exhaust heat in steam turbine. This "double use" gives higher thermal efficiency (45%+) vs conventional coal-fired plants (~35%). Also enables pre-combustion CO₂ capture.
| Impurity Removed | Method | Significance |
|---|---|---|
| Sulfur (as H₂S) | Desulfurization; Claus process; Rectisol process | 99.7% sulfur recovery as saleable elemental sulfur |
| Particulates (dust) | Cyclones, filters, scrubbers | Clean gas for turbines/chemical synthesis |

| CO₂ | Physical/chemical absorption (CCUS integration) | Pre-combustion CO₂ capture for blue hydrogen |
UPSC 2025 Prelims asked about products derivable from syngas via coal gasification (Statement-based). Key: Syngas → Ethanol (via fermentation or catalytic synthesis) ✅; Syngas → Ammonia ✅ (Haber-Bosch); Syngas does NOT produce Nitroglycerine ❌ (Nitroglycerine is from glycerol + nitration). Always verify exact syngas products.
| Linked Concept | Connection to Coal Gasification | Key Term / Article |
|---|---|---|
| Climate Change / NDC | Coal gasification = bridge technology; pre-combustion capture reduces GHG vs direct combustion; India's NDC: Net Zero 2070 | Paris Agreement 2015; NDC; Article 48A |
| CCUS (Carbon Capture, Use & Storage) | Gasification + CCUS → Blue Hydrogen (low-carbon); CO₂ captured pre-combustion from syngas stream; NTPC CO₂ borewell Jharkhand 2025 | CCS; CCU; CCUS; Blue Hydrogen |
| Atmanirbhar Bharat | Reduces import of LNG, urea, ammonia, methanol — ₹2.77 lakh crore FY25 import bill substitutable | Make in India; Aatmanirbhar Bharat |
| Methanol Economy (NITI Aayog) | 15% methanol blend in petrol → 1–5% crude import reduction; 20% DME in LPG → ₹6,000 Cr savings/yr; syngas primary methanol feedstock | DME; Methanol Economy |
| Hydrogen Economy | Syngas → Hydrogen extraction; coal gasification = 18% of world's hydrogen; with CCUS = Blue Hydrogen (cleaner) | Green Hydrogen vs Blue Hydrogen |

| Aspect | Advantage | Concern / Limitation |
|---|---|---|
| CO₂ emissions | Pre-combustion capture easier; CCUS integration possible → Blue Hydrogen | Gasification itself still produces CO₂; 18–20 kg CO₂ per kg H₂ produced (no CCUS) |
| SO₂ / NOₓ | 99.7% sulfur recovered as saleable product; NOₓ lower vs combustion | High ash Indian coal complicates sulfur removal |
| Air Quality | Local air quality improved vs direct combustion | Process energy-intensive; may offset some gains |
| Water Use | Modern IGCC uses less water per unit energy vs traditional coal-fired plants | Water treatment of ash/slag streams needed |
| UCG-specific | No surface mining; reduced land disturbance | Groundwater contamination risk; ground subsidence; carcinogen risk in aquifers |
| Net-Zero 2070 | Bridge technology — delays full transition cost | Critics: "fossil fuel lifeline"; not aligned with 1.5°C pathway without CCUS |
UPSC often links coal gasification to energy security, Methanol Economy, and NDC goals. Remember: Coal gasification is India's "bridge technology" — it does NOT directly replace renewables but reduces import dependence during the energy transition. Also: Blue Hydrogen = coal gasification + CCUS; Green Hydrogen = electrolysis with renewable energy — a common confusion tested in Prelims.
Cabinet approves ₹37,500 crore Coal Gasification Scheme (13 May 2026): Union Cabinet chaired by PM Modi cleared India's largest-ever coal-to-chemical push — the "Scheme for Promotion of New Surface Coal/Lignite Gasification Projects." The scheme incentivises gasification of ~75 MT of coal/lignite; provides up to 20% of plant & machinery cost; caps per-project incentive at ₹5,000 crore; per-group at ₹12,000 crore. Expected to attract ₹2.5–3 lakh crore investment across ~25 projects and generate ~50,000 jobs. Background: India's import bill for LNG, urea, ammonia, methanol, DME, ammonium nitrate, and coking coal stood at ₹2.77 lakh crore in FY25. The scheme is technology-agnostic but promotes indigenous tech and allows incentives to be clubbed with existing commercial coal mining schemes.
Rajya Sabha update — 7 projects listed (March 2026): Rajya Sabha proceedings on 23 March 2026 listed 7 coal gasification projects planned across Maharashtra, Odisha, and West Bengal with a total investment of ₹640 billion (₹64,000 crore). The flagship Talcher Fertiliser plant (JV: CIL-GAIL-RCF-FCIL) in Odisha is now expected to be commissioned by 2027–28. The Rajya Sabha session also highlighted persistent gaps — lack of a robust domestic business model, low JV participation from industry, and absence of tailored feedstock matching for high-ash Indian coal.
BCGCL–MCL land lease agreement signed (April 2026) — India's first indigenous coal gasification project: Bharat Coal Gasification & Chemicals Limited (BCGCL, JV of CIL + BHEL) signed a landmark land-leasing agreement with Mahanadi Coalfields Limited (MCL) for its coal-to-Ammonium Nitrate project at Lakhanpur, Odisha. Total investment: ₹11,768 crore; capacity: 0.66 MMTPA ammonium nitrate. This is the first time indigenous BHEL gasification technology will be deployed at commercial scale in India. Union Minister G Kishan Reddy described it as a "game-changer" for reducing import dependence and conserving foreign exchange.
NTPC enters coal gasification (November 2025): NTPC announced plans to enter coal gasification to produce clean fuel and fertiliser feedstocks from its captive coal mines. Target: produce 5–10 MT of gas by FY2026 at a production cost of USD 10–12/MMBtu. Tenders for technical consultants being prepared. The move aligns with NCGM's 100 MT by 2030 goal. Separately, a committee was constituted on 10 September 2025 to study feasibility of converting an existing gas-based power station to IGCC technology.
MMDR Amendment 2025 + High-Ash Coal Workshop: The MMDR Amendment Act 2025 (effective 01 Sep 2025) formally recognised coal gasification as a mining operation for the first time. On 02 Sep 2025, NITI Aayog hosted a workshop on High-Ash Coal Gasification Technology, chaired by Dr V K Saraswat. Separately, on 12 Dec 2025, the Ministry of Coal proposed amendments to MMDR recognising coal gasification as a mining operation (further regulatory strengthening), along with revision of mining area limits and lease tenure. CSIR-CIMFR submitted norms for coal-to-syngas conversion (June 2025) and UCG norms were finalised. China's Zhongshi Chemical Engineering (1st ever DPIIT registration, Oct 2025) allowed to participate as technology licensor in India.
14th Commercial Coal Mine Auction with UCG provisions (Oct 2025) + Ministry of Coal Year-End Review 2025: Ministry of Coal launched the 14th round of commercial coal mine auctions (29 Oct 2025) with 41 mines including UCG provisions for the first time — enabling use of deep-seated coal reserves through Underground Coal Gasification. Year-end review: Coal production from captive/commercial mines in 2025 = 203.70 MT (vs 180.66 MT in 2024 — growth of 12.75%). Coal supply assured for all 7 gasification projects under VGF Scheme I. Coking coal notified as Critical & Strategic Mineral under MMDR Act on 29 Jan 2026.
With UPSC Prelims 2026 on 24 May 2026 — just days after the ₹37,500 Cr Cabinet approval (13 May 2026) — this is extremely high-probability for a current affairs statement-type MCQ. Be ready for: amounts (₹37,500 Cr, 75 MT, 20% incentive cap), ministry (Ministry of Coal), target year (2030, 100 MT), products (urea, ammonia, methanol, LNG), and the distinction between VGF Scheme I (Jan 2024, ₹8,500 Cr) vs the new scheme (May 2026, ₹37,500 Cr).
| Statement | T/F | Reason |
|---|---|---|
| Coal gasification involves complete combustion of coal to produce syngas | ❌ FALSE | Gasification uses partial oxidation — coal is NOT fully burned. Complete combustion produces only CO₂ and H₂O. |
| Syngas produced by coal gasification can be used to produce Ethanol | ✅ TRUE | Syngas → Ethanol via catalytic synthesis or fermentation (UPSC 2025 Prelims — Statement I was correct) |
| Syngas can be used to produce Nitroglycerine | ❌ FALSE | Nitroglycerine is produced from glycerol (nitration of glycerol), NOT from syngas. (UPSC 2025 Prelims — Statement II was incorrect) |
| Syngas can be used to produce Urea (fertiliser) | ✅ TRUE | Ammonia (from H₂ in syngas via Haber-Bosch) + CO₂ → Urea. Core purpose of Talcher plant. |
| Underground Coal Gasification (UCG) requires conventional surface mining | ❌ FALSE | UCG converts coal to syngas in-situ within the seam — no conventional surface mining required. |
| India is the world's largest coal producer | ❌ FALSE | India is the 2nd largest coal producer (after China). Also 2nd largest consumer, 4th largest reserves. |
| NCGM targets 100 MT of coal gasification by 2025 | ❌ FALSE | NCGM target is 100 MT by 2030, not 2025. |
| The ₹37,500 crore coal gasification scheme was cleared by the Cabinet in January 2024 | ❌ FALSE | January 2024 Cabinet cleared the ₹8,500 crore VGF Scheme I. The ₹37,500 crore scheme was approved on 13 May 2026. |
| IGCC plants use syngas both in a gas turbine and a steam turbine, achieving higher efficiency | ✅ TRUE | IGCC = Integrated Gasification Combined Cycle; syngas powers gas turbine → exhaust heat makes steam for steam turbine = dual use → 45%+ efficiency. |
| Indian coal is low in ash content making it ideal for gasification | ❌ FALSE | Indian coal has high ash content (30–45%) — the single biggest challenge. Most global gasification tech designed for low-ash coal. |
Coal gasification is "cleaner than coal combustion" — NOT zero-carbon or renewable. Without CCUS, gasification still emits CO₂ (18–20 kg CO₂ per kg H₂ produced). Only coal gasification + CCUS = Blue Hydrogen (low-carbon). Never call gasification "clean energy" in absolute terms.
India has the 4th largest coal reserves globally (after USA, Russia, Australia). However, India is the 2nd largest coal consumer and 2nd largest coal producer. Students often mix up reserves rank vs producer/consumer rank.
Products derivable from Syngas (CO + H₂): Methanol, Ammonia, Urea, DME, SNG, Ethanol, Hydrogen, Olefins, Fischer-Tropsch diesel. Products NOT from Syngas: Nitroglycerine (glycerol-based), Biodiesel (transesterification of oils). UPSC 2025 tested this directly.
UCG = Underground Coal Gasification (in-situ, within seam, no mining). SCG = Surface Coal Gasification (coal mined first, then gasified above ground). India's Talcher, Lakhanpur, Dankuni = SCG. India's Kasta block, Jamtara = UCG pilot.
Coal Gasification = Ministry of Coal (not Ministry of Environment, not Ministry of Petroleum & Natural Gas, not Ministry of New & Renewable Energy). The NCGM is under the Ministry of Coal. NITI Aayog plays advisory role (Methanol Economy, steering committee). Ministry of Petroleum governs DME/methanol blending separately.
UPSC tests coal gasification via: (1) Statement-based MCQs on syngas products, process steps, types; (2) Scheme details — amounts, targets, ministry; (3) Match the following — project-location-product; (4) Current affairs hooks — latest Cabinet decisions, new policy terms (CGPDPA, UCG, VGF); (5) Linkage questions — coal gasification + Methanol Economy + Blue Hydrogen. The 2026 Prelims is likely to have at least one direct question given the 13 May 2026 Cabinet decision.
