“…Hence, among the numerous H2 production routes, the anaerobic DF process happens to be more efficient and significant since it has higher productivity and yield [17,18]. Additionally, DF produces H2 from numerous renewable biomass such as crop residues [19], lignocellulosic biomass [20], waste from organic material [21], and biomass algae [22,23]. Therefore, the production of H2 by DF is promising as it gives a higher H2 yield, and lower production and capital costs as compared to the PF process [24].…”

Biohydrogen production from renewable resources using dark fermentation has become an increasingly attractive solution in sustainable global energy supply. So far, there has been no report on the controllability analysis of biohydrogen production using dark fermentation. Process controllability is a crucial factor determining process feasibility. This paper presents a new criterion for assessing biohydrogen process controllability based on PI control. It proposes the critical loop gain derived via Routh stability analysis as a measure of process controllability. Results show that the dark fermentation using the bacteria from anaerobic dairy sludge and substrate source from sugarcane vinasse can lead to a highly controllable process with a critical loop gain value of 4.3. For the two other cases, an increase of substrate concentration from 10 g/L to 40 g/L substantially reduces the controllability. The proposed controllability criterion is easily adopted to assess the process feasibilty based on experimental data.
