In 2025, proton exchange membrane (PEM) technologies accounted for more than half of Europe's total water electrolyser manufacturing capacity, reaching **** GW per year. Alkaline electrolysis technologies represented roughly ** percent of total capacity, correspoinding to **** GW per year. Both technology types dominated European water electrolyser manufacturing capacity in 2025.Â
