Abstract
Hydrogen from renewable sources is crucial for climate goals, with water electrolysis as a key technology. This process also produces oxygen as a by-product, already used in various applications. This study evaluates the techno-economic potential of utilizing electrolysis-derived oxygen for the synthesis of ethylene oxide (EO) and vinyl acetate monomer (VAM). Depending on electricity prices, hydrogen production costs can be reduced by 6–12 % if oxygen is sold at market value. EO and VAM costs can decrease by up to 4.5 % if oxygen is provided for free. Integration into industrial clusters enhances synergies for hydrogen and oxygen utilization.
