Summary on Grant Application Form |

There is almost no information on yields of biohydrogen from continuous fermentative processes operating on mixed microflora on any substrate. Hydrogen yields from biomass by such a process will be established and optimised.With the help of ADAS, a suitable starch-based and lignocellulose-based biomass will be selected for experimentation. A mixed microflora will be operated continuously on non-sterile starch-based feed-stock at the maximum total so/ids giving stable operation, and process conditions giving optimal H2 yield established. Our previous studies on glucose substrate show H2 yield could be increased 68% by sparging with N2. Technically feasible strategies for lowering dissolved hydrogen levels and increasing H2 yield will be investigated. On-/ine instrumentation for process monitoring and optimisation includes novel use of a fuel cell to measure H2 in the off-gas, which will be evaluated. This work extends collaboration with a Japanese group in Tohoku University, Sendai, who are investigating photosynthetic H2 production. We propose the H2 fermentation stage be considered as part of a holistic system, where the effluent (rich in acetic acid) passes to well understood anaerobic digestion technology. The CH4 IH2 mix gives a cleaner bum than CH4 alone in conventional engines, or the gases can be used in fuel cells.
