Present and future cost of alkaline and PEM electrolyser stacks
We incorporate bottom-up with top-down costing approaches for stacks. Current stack cost range from 242 to 388 €/kW (AE) and 384–1071 €/kW (PEM). Stack costs may reduce to 52–79 €/kW (AE) and 63–234 €/kW (PEM) by 2030. Cost reductions are driven by higher current density (AE&PEM) and lower catalyst loading (PEM).
