1. A method for selective production of hydrogen and methane from a biomass feedstock in a reactor vessel maintained under anaerobic conditions, the method comprising:

  • a) introducing a biomass feedstock into a reactor vessel maintained under anaerobic conditions;

    b) introducing a bacterial inoculum into the reactor vessel to facilitate digestion of the biomass feedstock;

    c) setting a moisture concentration of contents of the reactor vessel at a first moisture level; and

    d) collecting hydrogen gas from the reactor vessel.
