What Does UCG Stand For?

UCG stands for Underground Coal Gasification

UCG, or Underground Coal Gasification, is a process that converts coal into gas while it remains underground. By injecting air or oxygen into coal seams, UCG facilitates the in-situ conversion of solid coal into synthesis gas (syngas), a mixture primarily composed of hydrogen, carbon monoxide, and minor amounts of other gases. This technology enables the efficient extraction of energy from coal deposits without the need for traditional mining, reducing surface environmental impacts and allowing for the utilization of low-quality or inaccessible coal resources. UCG has potential applications in energy production, chemical manufacturing, and carbon capture efforts.
