Context
Recently, the Union Cabinet has approved a substantial ₹37,500-crore financial package to incentivize and accelerate surface coal gasification projects across India. This initiative aims to utilize India’s vast coal and lignite reserves more sustainably while reducing the massive import bill for critical products like urea, methanol, and natural gas. The government has set an ambitious target to gasify 100 million tonnes (MT) of coal by 2030.
1. Financial and Policy Incentives
- CAPEX Subsidy: The government will provide financial incentives of up to one-fifth (20%) of the cost of plant and machinery.
- Project Caps:
- For a single project, the maximum financial incentive is capped at ₹5,000 crore.
- For a single product-centred project, the incentive limit is generally capped at ₹5,000 crore.
- However, projects related to:
- Synthetic Natural Gas (SNG) and Urea production can receive incentives up to ₹9,000 crore.
- A single entity/company can avail a maximum cumulative incentive of ₹12,000 crore across all project categories.
- Investment Certainty: To provide long-term stability, coal linkage tenures have been extended up to 30 years for gasification units.
- Target Capacity: The current package targets the gasification of approximately 75 million tonnes of coal and lignite, contributing to the broader 100 MT target for 2030.
2. Understanding Coal Gasification Technology
- Coal Gasification is a thermo-chemical process that converts coal into a gaseous mixture called Syngas (a mixture primarily composed of carbon monoxide and hydrogen) instead of burning it directly.
- The Process:
- The process occurs by reacting coal with a controlled amount of oxygen, steam, and heat under high temperature and pressure.
- Unlike direct burning, coal is partially oxidized, not completely combusted.
- Syngas Formation: Produces CO and H₂-rich gas.
- Gas Cleaning: Removal of impurities like sulfur, ash, and particulates.
3. Advantages over Direct Combustion
- Higher efficiency than conventional coal combustion
- Lower emissions of pollutants
- Can produce cleaner fuels and chemicals
- Helps reduce crude oil and natural gas imports
4. Uses in Modern Industries
· Power Generation: Syngas produced from coal gasification is used in Integrated Gasification Combined Cycle (IGCC) plants for efficient electricity generation.
· Fertilizer Industry: Hydrogen obtained from syngas is used in the production of ammonia and urea fertilizers.
· Chemical Industry: Used to manufacture chemicals such as methanol, ammonia, hydrogen, acetic acid, and synthetic natural gas (SNG).
· Steel Industry: Syngas and hydrogen can act as reducing agents in steel production, helping reduce coke consumption.
· Hydrogen Production: Coal gasification is an important source of industrial hydrogen for refineries and clean energy applications.
· Synthetic Fuel Production: Used to produce synthetic diesel, petrol, and aviation fuels through Fischer–Tropsch technology.
· Refinery Operations: Syngas is used in petroleum refining and upgrading low-quality fuels.
· Methanol Economy: Supports green and alternative fuel initiatives through methanol production for transport and marine fuel.
· City Gas & Industrial Fuel: Synthetic natural gas generated from coal gasification can be used for domestic cooking and industrial heating.
· Waste-to-Energy Applications: Integrated gasification technologies can process low-grade coal and industrial waste for energy recovery.
5. Why Coal Gasification is Important?
- Coal contributes over 55% of India’s energy mix. Coal gasification converts coal into syngas for producing fuels and chemicals domestically, reducing import dependence and exposure to global price volatility.
- The technology supports economic independence by utilizing India’s nearly 400 billion tonnes of coal reserves (fifth largest) to produce critical industrial feedstocks.
- Gasification is a “High Efficiency Low Emissions” (HELE) technology that acts as a bridge toward India’s Net Zero 2070 goal.
Consider the following statements regarding Coal Gasification:
1. Coal gasification converts coal into a gaseous mixture called syngas through partial oxidation.
2. Syngas mainly consists of carbon monoxide and hydrogen.
3. Coal gasification technology is primarily promoted for reducing India’s dependence on crude oil, urea, and natural gas imports.
Which of the statements given above are correct?
(a) 1 and 2 only
(b) 2 and 3 only
(c) 1 and 3 only
(d) 1, 2 and 3
Answer: (d) 1, 2 and 3
Explanation:
• Statement 1 is correct: Coal gasification converts coal into syngas using controlled oxygen, steam, and heat under high temperature and pressure.
• Statement 2 is correct: Syngas mainly contains carbon monoxide (CO) and hydrogen (H₂).
• Statement 3 is correct: The technology supports import substitution by enabling domestic production of methanol, urea, and synthetic natural gas (SNG).
