“…Despite the huge effort to shift the hydrogen economy to the clean energy sector, the majority of hydrogen is still produced via steam methane reforming (SMR), which stands as the predominant industrial process, utilizing high-temperature steam to react with methane, yielding hydrogen and substantial amounts of carbon-based emissions. Therefore, the growing interest in alternative hydrogen production methods is emphasized due to the transition towards sustainable energy systems, including electrolysis, solar water splitting, biomass gasification, thermochemical water splitting, or hydrolysis reaction [ 4 , 5 , 6 , 7 , 8 ]. While these methods have their own advantages and disadvantages, the hydrolysis reaction stands out from others due to unique characteristics, such as: (i) the process avoids external high temperatures or electricity provision; (ii) the hydrogen can be produced on-board; (iii) due to the exothermic reaction origin, it generates heat, which can be used as an additional reaction outcome; (iv) the reaction requires a reductant and water only; and (v) there are no carbon-based emissions during the reaction [ 9 , 10 , 11 ].…”

This study investigates the low-temperature hydrogen plasma treatment approach for the improvement of hydrogen generation through waste aluminum (Al) reactions with water and electricity generation via proton-exchange membrane fuel cell (PEM FC). Waste Al scraps were subjected to ball milling and treated using two different low-temperature plasma regimes: Diode and magnetron-initiated plasma treatment. Hydrolysis experiments were conducted using powders with different treatments, varying molarities, and reaction temperatures to assess hydrogen generation, reaction kinetics, and activation energy. The results indicate that magnetron-initiated plasma treatment significantly enhances the hydrolysis reaction kinetics compared to untreated powders or those treated with diode-generated plasma. Analysis of chemical bonds revealed that magnetron-initiated hydrogen plasma treatment takes advantage by promoting a dual procedure: Surface cleaning and Al nanocluster deposition on top of Al powders. Moreover, it was modeled that such H2 plasma could penetrate up to 150 Å depth. Meanwhile, electricity generation tests demonstrate that only 0.2 g of treated Al powder can generate approximately 1 V for over 300 s under a constant 2.5 Ω load and 1.5 V for 2700 s with a spinning fan.

This study evaluates the potential of several biomasses differing in nature and composition for their valorization by pyrolysis and in‐line oxidative steam reforming. The first task involved the fast pyrolysis of the biomasses in a conical spouted bed reactor at 500ºC, in which product yields were analyzed in detail. Then, the oxidative steam reforming of pyrolysis volatiles (gases and bio‐oil) was approached in a fluidized bed reactor. The reforming experiments were performed at 600 ºC, with an steam/biomass (S/B) ratio of 3 and catalyst (Ni/Al2O3) space times of 7.5 and 20 gcat min gvol‐1. Concerning equivalence ratio (ER), a value of 0.12 was selected to ensure autothermal operation. Remarkable differences were observed in H2 production depending on the type of biomass. Thus, pine wood led to a H2 production of 9.3 wt%. The lower productions obtained with rice husk (7.7 wt%) and orange peel (5.5 wt%) are associated with their higher ash and fixed carbon content, respectively, which limit the efficiency of biomass conversion to bio‐oil. However, in the case of the microalga, the poor performance observed is due to the lower conversion in the reforming step toward gases due to the composition of its pyrolysis volatile stream.
