The Hydrohub GigaWatt-Scale Electrolyzer project has produced an advanced design for such a 1-GW green hydrogen plant, which would use alkaline water electrolysis (AWE) and polymer electrolyte membrane (PEM) water electrolysis, and which could start up in 2030. This project shows that anticipated total investment cost levels of 730 €/kW or 1580 €/(kg/d) for AWE and 830 €/kW or 1770 €/(kg/d) for PEM are within reach. The CAPEX required will be about half of what would be required for the 2020 state-of-the-art design. This advanced design builds on a previous state-of-the-art 2020 baseline design, and foresees a considerable drop in […]
