• LIGNITE GASIFICATION TESTING AT THE POWER SYSTEMS ...

    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).
