Coal Gasification Concerns

The Future Of Cheap Energy: Underground Coal Gasification ...

Concerns and impacts of underground coal gasification Underground coal gasification is an experimental mining technology with a track record of failure, polluting the air, groundwater and soil. The process of burning coal underground for gas is difficult to control and produces many byproducts which are highly toxic.
