Li M.M., 2024, Efficiency and condition optimization of biohydrogen production using marine algae, Journal of Energy Bioscience, 15(5): 301-313 (doi: 10.5376/jeb.2024.15.0028)

This study optimizes the efficiency and conditions for biohydrogen production using algae, with a focus on enhancing the efficiency of the hydrolysis step during dark fermentation and improving photobiological hydrogen production. The study identifies macroalgae as an efficient biomass source for biohydrogen production, emphasizing the importance of pretreatment to enhance hydrolysis. Detoxification techniques are crucial to control inhibitory substances formed during pretreatment. Additionally, the use of oxygen scavengers such as sodium sulfite, sodium metabisulfite, and sodium dithionite significantly improves photobiological hydrogen production in Chlorococcum minutum, with sodium sulfite showing the highest efficiency. The review also highlights the potential of green algae and cyanobacteria as sustainable sources for biohydrogen, bioethanol, and biodiesel, and discusses the economic and environmental benefits of these methods. The findings suggest that optimizing pretreatment methods and using effective oxygen scavengers can significantly enhance biohydrogen production from marine algae. This not only provides a sustainable and clean energy source but also supports the transition to a circular bioeconomy. Further research into the economic feasibility and commercialization potential of these methods is recommended.
