Underground Coal Gasification (UCG) is in the news because the Ministry of Coal has recently launched a significant pilot project in Jharkhand’s Jamtara District. This initiative aims to harness UCG technology, which converts unmineable coal into valuable gas for energy production.
More context:
The pilot project’s success could pave the way for broader adoption of UCG technology in India, contributing to more sustainable and efficient use of coal resources.
Underground Coal Gasification (UCG) is a process that allows for the extraction of energy from coal deposits that are otherwise difficult or impossible to mine using traditional methods.
Concerns
Concern: The creation of voids in the coal seam during UCG can lead to subsidence, causing deformation in both the remaining coal and surrounding rocks.
Solutions:
Concern: Chemicals produced during UCG, such as phenols, benzene, and carbon dioxide, may migrate and contaminate groundwater sources.
Solutions:
Concern: The technology for converting India’s coal to syngas is not well-established, which affects the cost and viability of UCG projects.
Solutions:
Concern: UCG processes are inherently unsteady due to variables like cavity growth, coal properties, water influx, and ash buildup, which affect reaction rates.
Solutions:
Indian government has introduced several initiatives to advance coal gasification

Way Ahead
Attract Investment: Financial incentives, tax breaks, and subsidies can help make UCG projects more appealing to investors and companies, facilitating the development of new technologies and infrastructure.
