As India navigates the twin imperatives of energy security and net-zero commitments, coal gasification has emerged as a compelling transition technology; one that leverages existing resource abundance while moderating environmental costs.

The Process

Coal gasification converts solid coal into synthetic gas (syngas) – a mixture of hydrogen and carbon monoxide – through reaction with steam and oxygen, yielding urea, ammonia and methanol as downstream products.

The Case for Gasification

• India holds 401 billion tonnes of coal and 47 billion tonnes of lignite, yet imports one-fifth of its urea, nearly all its ammonia, and 80–90% of its methanol requirements.
• Coal gasification directly resolves this paradox by enabling indigenous production of fertilisers, chemicals, and synthetic fuels from domestic reserves, thus reducing import dependence.
• The National Coal Gasification Mission targets 100 MT of gasified coal by 2030, signalling strong policy intent.

Challenges in the Indian Context

• India's coal suffers from high ash content, variable calorific value, and complex mineral matter, making fluidised-bed gasification the more viable pathway.
• Projects face high capital intensity and long gestation periods, deterring private investment.
• Even at maturity, dependence on technological imports exposes a structural gap in India’s indigenous capability.
