Hydrogen as an energy source has been identified as an optimal pathway for mitigating climate change by combining renewable electricity with water electrolysis systems. Proton exchange membrane (PEM) technology has received a substantial amount of attention because of its ability to efficiently produce high-purity hydrogen while minimising challenges associated with handling and maintenance. Another hydrogen generation technology, alkaline water electrolysis (AWE), has been widely used in commer

Hydrogen energy became the most significant energy as the current demand gradually starts to increase. Hydrogen energy is an important key solution to tackle the global temperature rise. The key important factor of hydrogen production is the hydrogen economy. Hydrogen production technologies are commercially available, while some of these technologies are still under development. This paper reviews the hydrogen production technologies from both fossil and non-fossil fuels such as (steam reformin

The present study investigates the alumina particle size effect on hydrogen production from ammonia decomposition by dielectric barrier discharge plasma (DBD). Two different alumina particle diameters of 1 mm and 2 mm were used as a catalyst activation material. A low NH3 concentration of 0.5% was fed into the catalytic reactor at flow rates range of 0.1-1 L/min and dielectric barrier discharge plasma (DBD) voltage range of 12–18 kV. The decomposed gas samples were collected and measured by gas

This study describes the fundamentals of hydrogen-separation membranes and H2 separation modeling through Pd-based membranes. Furthermore, an assessment of hydrogen separation through a Pd-Cu 40% membrane was performed using two different feed gas concentrations (99.999% H2 and 75% H2−25% N2) and a dielectric barrier discharge (DBD) plasma in a cylindrical type reactor (CTR). The plasma was applied by combining zeolite catalyst materials (SA-600A and 330-HUDIA) in two different hydrogen concentr

The interest of hydrogen separation using palladium-based membranes has been raised due to their high permeability and selectivity. In this study, the performance of hydrogen permeation using dielectric barrier discharge (DBD) plasma in a microchannel plate reactor (MPR) was investigated. Pure hydrogen gas was injected into the MPR reactor at H2 flow rate of 0.1 L/min. The effect of plasma only, plasma-catalyst, plasma-heating, and the electrode gap distance (EGD) on the performance of H2 permea
