ABSTRACT:
A method for hydrogen production from biodegradable feedstocks in which a feedstock having at least one biodegradable solid is introduced into a first stage anaerobic bioreactor operating at thermophilic conditions to form a liquid effluent which includes fatty acids. The liquid effluent is transferred through a plurality of hollow semipermeable fibers disposed in a second stage anaerobic bioreactor having a light transmitting wall, which hollow semipermeable fibers have an outer surface coated with a biofilm of photosynthetic bacteria, which photosynthetic bacteria, using the nutrients in the hollow fibers and the incoming light, generates hydrogen.
