“…Waste lignocellulosic biomass requires different pretreatment technologies for enhancing biohydrogen production through dark fermentation by reducing the crystallinity of cellulosic and enhancing the access of microbial enzymes to ferment the sugars leading to biohydrogen production [129]. Various pretreatment processes involving physical, chemicals and biological agents have been adapted for biomass pretreatment prior to biohydrogen production [130]. In addition, pretreatment of inoculum also has the potential towards net biohydrogen production to destroy the hydrogen-consuming bacteria like hydrogenotrophic methanogens, homoacetogens, propionate producers, and sulfate-reducing bacteria [131][132][133].…”

Waste organic biomass is regarded as the most suitable renewable source for conversion to produce biofuels and biochemicals. Owing to its high‐energy potential and abundancy, lignocellulosic biomass can be utilized to produce alternative energy in the form of gaseous and liquid biofuels. Microbial conversion of waste biomass is the most successful technology for the generation of biohydrogen through dark fermentation. Different biological hydrogen production technologies along with process parameters are described in this review paper with the focus on dark fermentation. The production of biohydrogen from various substrates is summarized along with the integrated mode of dark fermentation and photofermentation. Hydrogen generation through biological water‐gas shift reaction is also highlighted.

Summary Renewable energies play a vital role in the economic and social development and progress of many countries. As one of the most significant sources of renewable energy, solar energy has been used due to its availability in many regions. Generating electricity for hydrogen production is one of the applications of solar energy. In petrochemical complexes, hydrogen is often used for producing fertilizers, especially urea fertilizers. The present study aims at investigating five major Iranian petrochemical complexes in terms of their suitability for the construction of a solar plant to produce electrolysis‐based green chemical fertilizers. To this end, a multicriteria decision‐making model is proposed, which includes the fuzzy analytic hierarchy process (AHP) and extended TODIM method of multicriteria decision making (including crisp, interval, and fuzzy numbers). The present research investigates 10 criteria for prioritizing petrochemical complexes, classified into four general categories, namely, climatic, geographic, environmental, and probability of natural disaster occurrence categories. Having calculated the weight of the criteria using the fuzzy AHP method, the alternatives are prioritized using the extended TODIM method. The methods of simple additive weighting (SAW), Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS), and VIKOR were then used for validation of the results. Results showed that the Shiraz Petrochemical Complex has the highest priority and Khorasan Petrochemical Complex has the lowest priority for producing green fertilizer via solar energy–assisted water electrolysis. By using the solar system, Shiraz Petrochemical Complex can emit over 1900 tons less pollutants in the environment per day and provides up to 8% of its annual total production through clean energy.

“…Hydrogen production by dark fermentation has great potential, because it does not require sunlight to operate, allowing full‐time operation and reducing complexity of the bioreactor setup. In addition, through dark fermentation, other value‐added by‐products can be produced concomitantly with hydrogen, for example, volatile fatty acids (acetic and butyric acid) and alcohols …”

Summary Different types of sludge pretreatments were tested, with thermal shock at 90°C to 95°C for 60 minutes plus a 6‐hour rest period achieving the best results for inhibition of methanogen microorganisms and inoculum enrichment with H2‐producing bacteria, which produced a H2‐rich biogas (up to 65% mol/mol) without the presence of CH4. Wastewater from biodiesel production (WBP), containing mainly methanol (128 g/L) and glycerol (4 g/L), was evaluated as a potential substrate to produce H2 through dark fermentation. Both methanol‐based solutions and methanol‐rich wastewater were not suitable for hydrogen production; however, these effluents showed a strong potential for CH4‐rich biogas production. A fractional factorial design was employed to evaluate the effect of six substrate‐related variables (glycerol content, 25% and 75%; COD content, 4 and 50 g/L, COD:VSS ratio, 1:1 and 5:1; COD:N:P ratio, 350:0:0 and 350:5:1; NaCl content, 0.5 and 12.0 g/L; and pH, 4.0 and 5.5) on the H2 production from glycerol‐methanol–based synthetic solutions (synthetic WBP). Some substrate‐related variables had a crucial impact on the hydrogen production potential from WBP, which was significantly affected by the COD and salinity content in the substrate. WBP containing high glycerol (representing until 75% of the COD) and salinity (up to 12 g/L as NaCl) content could be turned into a potential substrate for H2 production through dark fermentation as long as specific fermentation conditions are maintained, such as pH 5.5 to 5.7 and a substrate COD content up to 50 g/L. Using this condition, glycerol conversion, H2 productivity, and H2 yield of 81.3 ± 8.9%, 102.8 ± 18.2 mL H2/L.d, and 24.5 ± 4.4 mL H2/g CODapplied, respectively, were obtained.
