Coal gasification is the process of converting coal into synthesis gas (also called syngas), which is a mixture of hydrogen (H2), carbon monoxide (CO) and carbon dioxide (CO2). The syngas can be used in a variety of applications such as in the production of electricity and making chemical products, such as fertilisers.

India has the fourth largest reserves of coal in the world. Indian coal reserves as per the latest estimate of Geological Survey of India, including coal and lignite up to a depth of 1200 m, are 327 Billion tonne (Bt) (GSI, 2011), out of which coal is 286 Bt and lignite 41 Bt in two important geological horizons of Permian (250300 million years) and Tertiary Periods (65180 million years).
![[Indepth] [Updated] Coal Sector in India IAS EXPRESS](/cud8b96/175.jpg)
The coal reserves in India are some of the largest in the world (5th biggest reserve). Most of the coal deposits in India is of the bituminous type. These are mostly noncoking coal. This is the reason for our import dependence in the sector. Most of the coal deposits in India is of the Gondwana type (about 99%).
