Coal gasification is a process that converts coal into syngas (a mixture of hydrogen, carbon monoxide, and carbon dioxide) through high-temperature reactions with oxygen and steam. The combustion of this gas is cleaner and more efficient than coal combustion since emissions are trapped at the gasification stage..This technology enhances energy security by utilising abundant domestic coal resources and aligns with environmental sustainability goals, balancing economic growth with ecological responsibility.

Impact of Coal Gasification on India’s Energy Security and Environmental Sustainability:

Energy Security:

• Diversification of Energy Sources: Coal gasification offers an alternative to conventional coal usage, reducing reliance on oil and natural gas imports, thereby enhancing energy diversity and security.
  For example: The government has launched the National Coal Gasification Mission to achieve coal gasification and liquefaction of 100 MT of coal by 2030.
• Domestic Coal Utilisation: Utilising India’s vast coal reserves through gasification ensures a stable, domestic energy supply, decreasing dependence on fluctuating international energy markets.
  For example: India has the second-largest coal reserves after China, providing a substantial resource base for energy security through coal gasification projects.
• Production of Syngas: Syngas from coal gasification can be used in various industries, providing a versatile and reliable energy source for electricity, chemicals, and fuel production.
  For instance: Syngas can be used in the production of active pharmaceutical ingredients (APIs) and methanol as a solvent,  reducing dependence on imports from China .
• Enhanced Fuel Production: Coal gasification facilitates the production of cleaner fuels like hydrogen and methanol, supporting a diversified and secure energy portfolio.
  For instance: India heavily depends on crude and natural gas imports for methanol, ammonia, ammonium nitrate, and olefins, which can be easily substituted by by-products of syngas.
• Energy Independence: By reducing the need for imported fuels, coal gasification contributes to national energy independence, safeguarding against geopolitical risks.
  For instance: India imports approximately 50% of its natural gas, highlighting dependence on foreign energy sources, which impacts national energy security and economic stability.
• Reliability in Energy Supply: The stable output from coal gasification plants ensures a consistent energy supply, critical for industrial and economic stability.
  For example : The Jindal Steel and Power Limited (JSPL) plant in Angul, Odisha, effectively uses local coal reserves for gasification, ensuring a steady local energy supply.
• Economic Growth: Enhanced energy security through coal gasification can drive industrial growth and economic development by providing reliable energy at competitive costs.
  For instance: Coal gasification can contribute to India’s vision of Aatmanirbhar Bharat and create a surge in employment opportunities.

Environmental Sustainability:

• Emission Reductions: Coal gasification emits fewer pollutants compared to traditional coal burning, contributing to improved air quality and reduced greenhouse gas emissions.
  For example: Initiatives under coal gasification support the National Clean Air Programme (NCAP) which  aims to reduce PM2.5 and PM10 levels by 20-30% by 2024. 
• Carbon Capture and Storage (CCS): Integrated CCS in coal gasification plants can significantly reduce carbon emissions, aligning with climate change mitigation goals.
  For example : It supports NITI Aayog’s vision for a sustainable future  which includes the implementation of Carbon Capture, Utilisation, and Storage (CCUS) technologies in coal gasification projects.
• Efficient Use of Resources: By converting low-grade coal and waste into valuable energy, coal gasification maximises resource efficiency and minimising waste.
  For instance: With India’s projected power demand set to increase coal needs from nearly one billion to 1.5 billion tonnes by 2029-30, efficient coal gasification can help meet this rising demand and optimise resource use.
• Cleaner Fuel Production: The process produces cleaner fuels like hydrogen, reducing the environmental impact of energy consumption and supporting clean energy transitions.
  For instance: Coal gasification plants produce no scrubber sludge, reducing the environmental burden of waste disposal associated with conventional coal plants.
• Water Management: Although water-intensive, advancements in water recycling and management can mitigate the environmental impact of water use in coal gasification.
  For instance:The majority of the wash water is reprocessed, and residual wastewater from gasification plants can be treated effectively, mitigating environmental impact.
• Reduced Land Degradation: Coal gasification can utilise less land compared to traditional mining and combustion methods, reducing land degradation and ecological impact.
• Support for Renewable Integration: By providing a stable energy source, coal gasification can complement renewable energy sources, ensuring a balanced and sustainable energy mix.
  For example : Coal gasification provides a reliable energy source that supports the National Solar Mission, ensuring a stable and balanced energy supply.

India’s focus on coal gasification aligns with its long-term goal of reaching net-zero emissions by 2070. This approach underscores the nation’s dedication to innovative energy solutions that foster sustainable development and address environmental challenges effectively.
