Biomass and/or fossil fuels, together with hydrogen from an external source, are fed to a hydrogasification reactor.

The system includes a hydrogasification reactor, a pressurized feed system, a hopper system, a hydrogen gas source, and a carrier gas source.

Molten salt loops are used to transfer heat from the hydro-gasification reactor, and Fischer-Tropsch reactor if liquid fuel is produced, to the steam generator and the steam pyrolytic reformer.

The method allows control of the H2/CO syngas ratio by adjusting the hydrogen feed and the water content of feedstock into a steam hydro-gasification reactor that supplies the SMR.
