A system for using carbonaceous material includes a steam reformer, a hydrocarbon reformer, and at least one gas-cleanup system. Also described are methods of producing liquid fuel and/or chemicals from carbonaceous material.

Combining multiple subsystems involving biomass processing, biomass gasification of the processed biomass where a synthesis gas is produced then converted to hydrogen fuels or other transportation fuels for use in coupled transportation systems sized to consume all the transportation fuel produced. Carbon in the biomass is converted to CO.sub.2 in the conversion process and a portion of that CO.sub.2 is captured and sequestrated for long term storage.
