X-SEED Project: Supercritical membrane-less electrolysis

under development

X-SEED is a European research initiative developing supercritical, membrane-less electrolysis technology to advance renewable hydrogen production. The project aims to improve efficiency, durability, and cost competitiveness of electrolysers by operating at higher pressures and temperatures without a membrane, using controlled water flow to separate gases. The technology is validated at laboratory scale with a five-cell electrolysis stack and targets system-level energy consumption and cost reductions to support Europe's renewable hydrogen goals.
