The DOE Working Group for an Assessment of Coal-Gasification Research Needs (COGARN - coal gasification advanced research needs) has reviewed and evaluated US programs dealing with coal gasification for a variety of applications. Cost evaluations and environmental-impact assessments formed important components of the deliberations. We have examined in some depth each of the following technologies: coal gasification for electricity generation in combined-cycle systems, coal gasification for the production of synthetic natural gas, coal gasifiers for direct electricity generation in fuel cells, and coal gasification for the production of synthesis gas as a first step in the manufacture of a wide variety of chemicals and fuels. Both catalytic and non-catalytic conversion processes were considered. In addition, we have constructed an orderly, long-range research agenda on coal science, pyrolysis, and partial combustion in order to support applied research and development relating to coal gasification over the long term. The COGARN studies were performed in order to provide an independent assessment of research needs in fuel utilization that involves coal gasification as the dominant or an important component. The findings and research recommendations of COGARN are summarized in this publication.
