“…Depending on the type of feedstock, pretreatment is used to enhance the accessibility of cellulose in the lignocellulosic feedstock to enzymes that convert carbohydrate polymers into fermentable sugars (Mosier et al, 2005). The pretreated feedstocks (WS, SSS) are further broken down into fermentable sugars using commercial enzymes such as cellulase, glucoamylase (AMG 300), and thermamyl (Claassen and de Vrije, 2006). It should be mentioned that under the same conditions of enzyme loading, the amounts of enzyme required for SPP, SSS, and WS at the same feedstock flow rates differ because the feedstock materials contain different amounts of polysaccharide (starch and cellulose).…”

“…In such an integrated process, carbohydrates are converted to hydrogen, carbon dioxide, and intermediates during dark fermentation which is followed by a consecutive photofermentation during which all the intermediates are converted to hydrogen and carbon dioxide. As a result the overall hydrogen yield is maximized [3,4].…”

“…During dark fermentation, maximum hydrogen yield is obtained when all sugars are fermented to acetate (C3 mol of hydrogen/hexose sugar); production of more reduced fermentation by-products like lactate, butyrate, propionate, and ethanol results in lower hydrogen yields (1-2 mol of hydrogen/hexose) [3,5].…”

Photofermentative production of hydrogen is a promising and sustainable process; however, it should be coupled to dark fermentation to become cost effective. In order to integrate dark fermentation and photofermentation, the suitability of dark fermenter effluents for the photofermentative hydrogen production must be demonstrated. In this study, thermophilic dark fermenter effluent (DFE) of sugar beet thick juice was used as a substrate in photofermentation process to compare wild-type and uptake hydrogenase-deficient (hup (-)) mutant strains of Rhodobacter capsulatus by means of hydrogen production and biomass growth. The tests were conducted in small-scale (50 mL) batch and large-scale (4 L) continuous photobioreactors in indoor conditions under continuous illumination. In small scale batch conditions, maximum cell concentrations were 0.92 gdcw/L c and 1.50 gdcw/L c, hydrogen yields were 34 % and 31 %, hydrogen productivities were 0.49 mmol/(L c·h) and 0.26 mmol/(Lc·h), for hup (-) and wild-type cells, respectively. In large-scale continuous conditions, maximum cell concentrations were 1.44 gdcw/L c and 1.87 gdcw/L c, hydrogen yields were 48 and 46 %, and hydrogen productivities were 1.01 mmol/(L c·h) and 1.05 mmol/(L c·h), for hup (-) and wild-type cells, respectively. Our results showed that Rhodobacter capsulatus hup (-) cells reached to a lower maximum cell concentration but their hydrogen yield and productivity were in the same range or superior compared to the wild-type cells in both batch and continuous operating modes. The maximum biomass concentration, yield and productivity of hydrogen were higher in continuous mode compared to the batch mode with both bacterial strains.

“…The combustion process of hydrogen itself is free of CO 2 emission and can therefore be a part of a low-carbon energy system. It is important to note that there is still some research required to meet the challenges regarding the storage of hydrogen and the production from renewable energy sources [2].…”

Hydrogen is used as an important feedstock for the chemical industry. Common production technologies for the production of hydrogen from fossil fuels today cause relevant CO 2 emissions. Hydrogen from renewable energy sources is discussed as an alternative option to replace traditional feedstock and can therefore be part of a low-carbon energy system. This paper describes the results of a simulation of a concept for the production of hydrogen with biomass as feedstock. The described investigations include a possible process design, the process simulation using the software IPSEpro, a description of the operation characteristics, and a profitability analysis of the applied hydrogen production concept. The simulation result shows that 61 MW of hydrogen can be produced from 100 MW wood chips and 6 MW of electricity. As a result, hydrogen production costs of 54 €/MWh can be estimated. For the investigated concept, the wood chip price is the most important factor for the hydrogen production cost followed by investment costs for the plant and the realized plant operation time per year.
