The available electrolysis-technologies (AEL, PEMEL, SOEL) are assessed concerning their development status and future potential (electric energy demand, stack life time etc.). Furthermore, the future hydrogen demand in Germany is predicted by the use of the REMod-D-tool in a scenario analysis and the installation of the necessary electrolysis-capacity is evaluated concerning potential challenges. The technology development and production processes of electrolysers are not identified as bottlenecks. Water-electrolysis is ready for market roll-out - solely the resource use and regulatory frameworks hamper the predicted development. The depicted roadmap for the industrialization of water-electrolysis supplies an overview about necessary measures for supporting the market roll-out of the technology.enWasserstofftechnologieWasserstofferzeugung durch Elektrolysechemische EnergiespeicherungElectrolysisdemandroadmapBundesrepublik Deutschlanderneuerbare EnergieSektorkopplungSkalierungWasserelektrolyse621697presentation
