Coal Gasification: India’s Strategic Path to Energy Sovereignty

Context

India has been taking the initiative to speed up the development of coal gasification for boosting its energy security by decreasing dependency on natural gas and chemical feedstock imports from abroad, as well as minimizing the effect of global supply chain disruptions. The government has set a target of 100 MT of coal gasification by 2030, which will help to reduce the dependence on foreign coal and improve the country’s environmental sustainability, especially for high-ash domestic coal. 

Context: Global Disruptions & India’s Energy Scene

• Crude oil dependency: India is importing more than 80% of crude oil and natural gas is more than 50%. 
• Supply Volatility: India’s global price hikes (from $177 to $435 per ton from 2021 to 2022) highlight the need to cut down on import dependence on coal. 
• Domestic Consumption: Coal will continue to be the main source of energy in India, accounting for 55% of energy consumption, and demand is projected to increase to 1.5 billion tonnes of coal by 2030. 

What is Coal Gasification?

Thermo-chemical process that converts solid coal into syngas (mixture of hydrogen, carbon monoxide and carbon dioxide) without burning the coal. It can be used to make chemical products such as methanol, fertilizers and hydrogen, providing a cleaner alternative to the traditional burning of coal to produce these products. 

Why Gasification? Advantages for India

• Lower import dependence: It helps to reduce the dependence on methanol, ammonia, natural gas imports. 
• High Ash Coal: Coal is available with high ash content in India which is difficult for combustion directly. Gasification is a more efficient utilization method. 
• Energy Security & Strategic Shift: It contributes to the mission of “Aatmanirbhar” and helps in risk reduction of the Geopolitical environment. 
• Environmentally Cleaner: emits less pollutants such as SOx and NOx than direct coal combustion. 

Government Initiatives & Targets

• National Coal Gasification Mission: Gasification capacity of 100 MTPA by 2030.
• Incentive Framework: ₹8,500 crore Viability Gap Funding (VGF) will be provided for both the private and the public sectors.
• Private Sector Involvement: The coal sector is opened to the private sector and private investment in the gasification is encouraged (Commercial Mining Policy 2020).

Challenges & Future Outlook

• High Capital Initial Costs: Gasification plants are expensive.
• Reduced Conversion Efficiency: Solid to gas conversions may be energy intensive.
• Environmental Concerns: The process is cleaner, but is still emitting CO2, which needs to be captured effectively.
