Abstract

This chapter delves into the environmental and economic analysis of integrating oxygen liquefaction with green hydrogen production, utilizing renewable energy sources to enhance economic feasibility. The study focuses on a 50 MW electrolysis plant with an integrated oxygen liquefaction unit, powered by a mix of solar photovoltaic and wind energy. The life cycle analysis (LCA) reveals significant reductions in global warming potential (GWP) when compared to traditional methods, with the best-case scenario showing an 81% reduction. The economic analysis demonstrates that using a higher ratio of solar energy can lower the levelized cost of hydrogen (LCOH) and liquid oxygen (LCOLO2), making the process more cost-effective. The chapter also provides a detailed breakdown of the materials and energy requirements for the oxygen liquefaction unit, offering a holistic view of the environmental and economic impacts of this integrated system. The results underscore the potential of renewable energy sources in promoting sustainable green hydrogen production and a cleaner environment.
