Electrolyzer Manufacturers — United Kingdom
135 electrolyzer companies in United Kingdom. European electrolyzer capacity needs to scale from ~1 GW installed (2024) to 100 GW by 2030 per REPowerEU targets. Three dominant technologies compete: PEM (fast response, high cost), alkaline (mature, lower cost), and SOEC (highest efficiency, least mature). Stack costs dropped 40% since 2020 but remain at €500-1,200/kW.
