Case study of a site-specific design and operation optimization of a wind farm co-located PEM electrolyzer and BESS including degradation

Short summary

Neglecting electrolyzer degradation and part-load efficiency in hybrid wind-hydrogen systems can overestimate annual operational profits by 35% and underestimate the levelized cost of hydrogen (LCOH) by EUR 1.2/kg. Including battery storage reduces electrolyzer degradation by 20% and increases annual profit by 7%.
