What is underground coal gasification?
Underground Coal Gasification (UCG) is a gasification process applied to non-mined coal seams, using injection and production wells drilled from the surface, which enables the coal to be converted in-situ into product gas for both chemical processes and power generation. The company plans to design and test processes to prevent or minimise the traditional environmental impacts on air, soil and water. The process is planned to be conducted in such a way that gasification pressure in the gas seams is always slightly less than the hydrostatic pressure of fluid in the coal seam and surrounding strata. As a result, flow from the gasifer into the surroundings is minimised, thereby preventing both the loss of valuable product and contamination of the underground environment. UCG can be a more environmentally friendly and energy-efficient technology for producing competitively priced gaseous or liquid fuels.
