The X-SEED project is focused on developing a supercritical, membrane-less electrolysis technology to produce hydrogen more efficiently. Operating at 374°C and over 220 bar, this design eliminates membrane-related energy losses and lowers maintenance costs.
The project aims for system-level energy consumption to be less than 42 kWh per kg of hydrogen, with a target levelized cost under 3 €/kg. Currently, X-SEED is validating materials and processes, including Inconel substrates and various catalysts, and has made significant progress in scaling from single-cell to short-stack configurations.
The consortium plans to implement gas and energy management strategies to ensure safe and efficient operations. Achieving the project's goals could significantly enhance the economic viability of green hydrogen production across multiple sectors.
