Lignite coal presents opportunities as well as challenges as a feedstock for an integrated gasification combined cycle power plant. It is relatively inexpensive, easily accessible for mining, highly reactive and thus readily converted to syngas, and it is abundant—accounting for nine percent of demonstrated coal reserves (EIA, 2007).

IGCC and Gasification Background • Coal gasification first used for streetlights in 1792. • Late 1800's widely used for lighting and industrial applications in Europe and US. • By the 1920's there were over 1200 gas plants operating in the US. Post WW II discoveries of natural gas led to demise of these plants.
