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.

水电解产生的氧气作为化学合成的饲料
来自可再生能源的氢对实现气候目标至关重要,水电解是一项关键技术。这个过程还会产生副产品氧气,已经在各种应用中使用。本研究评估了利用电解衍生氧合成环氧乙烷(EO)和醋酸乙烯单体(VAM)的技术经济潜力。根据电价的不同,如果以市场价格出售氧气,氢气的生产成本可以降低6 - 12%。如果免费提供氧气,EO和VAM的成本可以降低4.5%。融入产业集群增强了氢氧利用的协同效应。
