Summary: Different pretreatment methods, including lyophilization, hydrothermal pretreatment, and ultrasound combined with dilute alkali post-cooking, were investigated to enhance the efficiency of enzymatic saccharification and biohydrogen production of wheat straw. All methods effectively removed lignin and hemicellulose while retaining cellulose, improving biomass accessibility. Ultrasound combined with dilute alkali cooking produced a reducing sugar concentration of 13.18 g/L and a sequential fermentative hydrogen yield of 133.6 mL/g total solids.

Summary: This study examined the working mechanisms of acetic acid inhibition on dark fermentative hydrogen production. The results showed that undissociated acetic acid concentration was the critical factor in acetic acid inhibition. Acetic acid inhibited hydrogen production by altering the dominant microbial community and regulating the metabolic pathways. Controlling the undissociated acetic acid concentration would be an effective strategy to alleviate acetic acid inhibition.

Summary: The most critical development in conventional underwater applications in recent years is the use of hydrogen energy systems, particularly Air Independent Propulsion (AIP) systems powered by Proton Exchange Membrane (PEM) fuel cells. These systems have gained worldwide interest due to their advantages in terms of longer endurance time, silent operation, environmental friendliness, high efficiency, and low thermal dissipation. However, the storage of hydrogen presents a significant challenge in terms of quality, weight, and volume. Different hydrogen storage techniques are required for unmanned underwater vehicles with varying volume and weight requirements.
