Hydrogen is vital for the chemical and petrochemical industries and as an energy source, but its current production from fossil fuels leads to significant carbon emissions. Biomass-derived resources, such as bio-oil and bioethanol, offer an eco-friendly alternative to fossil-based production. Bioethanol, generated from sugar fermentation, possesses favorable attributes including a high octane number, low greenhouse gas emissions and compatibility with existing infrastructure. It not only reduces dependence on fossil fuels but also lowers net CO2 emissions significantly. Ethanol steam reforming (ESR) technologies, particularly in membrane reactors (MR), provide high-purity H2 production by integrating catalysis and selective separation . Pd-based membranes excel at extracting H2 from gas mixtures.
