The GreenHyScale project aims to accelerate largescale production of green hydrogen by building and operating the first 100 MW green electrolysis plant. The plant will be erected in GreenLab at Skive, Denmark, and replicable in the rest of the world for greater impacts. The partners will use pressurised alkaline electrolysis to enable large-scale production of green hydrogen – which will make the establishment of a commercially viable hydrogen infrastructure possible.
