Capacity values retain their recorded units and scope. MW, kt H₂/y and Nm³ H₂/h are different measures; this page does not convert or add them without a shared operating basis. “Other Electrolysis” and “Unknown PtX” are recorded classifications, not a specific electrolyzer design or power-to-X route.
