The new report from ISPT is the culmination of the Hydrohub Gigawatt Scale Elektrolyser project, and presents a detailed design for an advanced, GW-scale green hydrogen plant. The greenfield design could be up-and-running in a Dutch port area by 2030, and would have total investment cost levels of 730 €/kW for alkaline water electrolysis, or 830 €/kW for PEM water electolysis. This translates to about half the CAPEX required for a state-of-the-art design from 2020.
A raft of technological optimisations make the impressive cost drop possible, but the authors note that a significant amount of R&D, pilot projects and demonstrations are required to put all the optimisation pieces together. Speed and haste are also required: 2030 is presented in the report’s foreword as a deadline, not an aspiration.
