The objective of OUTFOX is to eliminate the scale restriction in the implementation of Solid Oxide Electrolysis (SOEL) technologies and demonstrate their potential as the preferred option for producing green hydrogen. Through the integration of experimental findings up to the 80kW scale and the identification of optimal cell and system designs, OUTFOX plans to equip SOEL for large-scale industrial systems of over 100MW with a reduced Levelized Cost of Hydrogen of €2.7/kg H2 and suitability for mass manufacturing lines. The industrially driven consortium will pool its expertise in cell, stack, and module development, along with manufacturing and full system evaluation, to advance the maturity of SOEL and contribute to the objectives of the Clean Hydrogen JU SRIA. The overall sustainability will be enhanced by reducing overall material requirements, where OUTFOX will achieve current densities of at least 0.85 A/cm2 using cells that are 25% thinner than the current state-of-the-art cells.
Scaling up will be approached from two angles:
1. Developing and validating cells with geometrical areas of up to 900 cm2 that are compatible with large-scale manufacturing techniques; and
2. Validating optimized design concepts up to the full module level for commercial scale implementation
The partners will test high current density operation with reference scale (144 cm2), industrial scale (>300cm2), and next-generation (900cm2) cells in single repeating units, short stacks of 15 cells, and 80kW prototype systems, resulting in over 10,000h of SOEL operation. To provide comprehensive validation of the OUTFOX technology, 2 distinct 80 kW testing campaigns with 2 different stack configurations will be conducted at the Shell facilities in Amsterdam, with over 4000 operating hours in total. This will offer crucial data for designing a 100+ MW SOEL system, including module configuration and balance of plant requirements, enabling a multi-MW demonstration after the project's conclusion.
