The emission of greenhouse gases (GHGs) has escalated to unprecedented levels due to the extensive use of fossil fuels for industrial development and population growth. Consequently, the transition to clean and renewable energy sources is critical for mitigating climate change. Hydrogen is considered a promising energy carrier that can be produced from both conventional (fossil fuels) and renewable resources (biofuels and water). Among renewable sources, ethanol is favored over other bioalcohols because it has a high energy content and is less toxic than hydrocarbon fuels. In addition, ethanol reforming represents a viable method of efficiently producing renewable hydrogen. To enhance this process, innovative technologies have been developed, particularly through the use of a membrane reactor (MR) technology. In MRs, the reaction and separation processes occur simultaneously, which improves the selectivity and yield while reducing operating conditions and preventing coke formation. This study aims to highlight recent advancements in ethanol reforming reactions�including steam reforming, partial oxidation, and autothermal reforming reactions�to produce renewable, low-carbon hydrogen using MR technology. In particular, the central focus is to provide a comprehensive analysis of the performance of different MRs, shedding light on their efficacy, scalability, and potential limitations in the context of renewable hydrogen production from ethanol reforming. By exploring these aspects, this study attempts to inform strategic decisions and advancements in sustainable energy technologies, facilitating the transition toward a greener, more resilient energy landscape.

Hydrogen separation has significant importance in diverse applications ranging from clean energy production to gas purification. Membrane technology stands out as a low-cost and efficient method to address the purpose. The development of efficient gas-sensitive materials can further bolster the membrane's performance. In this pursuit, bimetallic PdPt nanoparticles were synthesized using a wet chemical approach and were strategically decorated onto poly(ether sulfone) (PES) membranes. The fibrous morphology of the PES membranes provided an ideal platform for the decoration of nanoparticles, promising enhanced gas transport properties. Prior to the attachment of nanoparticles, the membranes were pretreated under UV light to enhance their surface properties and facilitate improved adhesion. The synthesized bimetallic nanoparticles were characterized by using transmission electron microscopy and X-ray photoelectron spectroscopy for their morphological and elemental analysis. Furthermore, the engineered membranes were characterized using various techniques, such as Fourier transform infrared (FTIR) spectroscopy, Raman spectroscopy, and field emission scanning electron microscopy (FESEM) with rigorous scrutiny to ensure a comprehensive understanding of their structural, chemical, and morphological properties. The membranes were examined for their separation performance using pure H 2 , N 2, and CO 2 gases, and the results revealed a 30% increment in H 2 permeability and 40 and 42% increments in H 2 /CO 2 and H 2 /N 2 selectivity, respectively. These findings confirmed the critical role of tailored material design and synthesis strategies in advancing membrane technologies for H 2 separation applications.
