Context:
• The Union Government highlighted the ₹8,500 crore Coal Gasification Incentive Scheme as part of India’s roadmap to reduce dependence on imported petroleum, ammonia, and fertilizers.
Key Highlights:
Government Initiative / Policy Details:
• Approved on January 24, 2024.
• Aims to promote coal and lignite gasification projects across public and private sectors.
• Total financial outlay: ₹8,500 crore.
• Target: Achieve 100 million tonnes of coal gasification by 2030.
• Forms part of India’s clean coal transition strategy.
Categories of Projects:
• Category I: PSU-led projects
• Category II: Joint/private + PSU participation
• Category III: Demonstration & small-scale projects
Scientific Principle – Coal Gasification:
• A thermo-chemical process converting coal into syngas.
• Syngas composition: Carbon Monoxide (CO), Hydrogen (H₂), Carbon Dioxide (CO₂), Methane (CH₄), Water Vapour (H₂O).
• Occurs at 1000–1400°C using limited oxygen and steam.
Process Steps:
• Preparation: Coal is crushed to increase surface area
• Gasification: Reaction with oxygen/steam in reactor
• Chemical Conversion: Partial oxidation produces syngas
• Gas Cleaning: Removal of tar, sulfur, and particulates
Stakeholders Involved:
• Ministry of Coal
• Public Sector Undertakings (PSUs)
• Private sector companies
• Energy and fertilizer industries
Significance / Applications:
• Reduces reliance on imported fossil fuels and fertilizers
• Enhances energy security
• Enables production of cleaner fuels and chemicals
• Promotes industrial growth and technological innovation
• Potentially lowers environmental impact compared to direct coal burning
Relevant Prelims Points:
• Coal gasification produces syngas, not liquid fuel directly.
• Operates under limited oxygen (partial oxidation) conditions.
• Temperature range: 1000–1400°C.
• Target: 100 million tonnes by 2030.
• Scheme outlay: ₹8,500 crore.
• Includes PSU-led, private participation, and pilot projects.
• Syngas can be used to produce:
- Methanol
- Ammonia (fertilizer)
- Hydrogen fuel
• Supports India’s Atmanirbhar Bharat and energy transition goals.
Relevant Mains Points:
- Role in Energy Security:
- Reduces dependence on crude oil imports, improving trade balance
- Utilizes abundant domestic coal reserves efficiently
- Industrial and Economic Impact:
- Promotes downstream industries (fertilizers, chemicals, fuels)
- Encourages private sector investment and PPP models
- Boosts Make in India and manufacturing ecosystem
- Environmental Considerations:
- Cleaner than conventional coal combustion but still carbon-intensive
- Requires integration with Carbon Capture, Utilisation and Storage (CCUS) for sustainability
- Helps reduce particulate pollution
- Challenges:
- High capital costs and technological complexity
- Need for advanced gas cleaning infrastructure
- Environmental concerns if carbon emissions are not managed
- Water-intensive process
- Strategic Importance:
- Supports green hydrogen mission through syngas conversion
- Enhances self-reliance in fertilizers (ammonia production)
- Aligns with India’s net-zero goals (with mitigation technologies)
- Way Forward:
- Integrate CCUS technologies to reduce emissions
- Provide policy stability and incentives for private players
- Promote R&D in cleaner coal technologies
- Ensure environmental safeguards and water efficiency
- Align with renewable energy transition for balanced energy mix
