The project is advancing high-temperature electrolysis through the development and ongoing assembly of a 1 MW solid oxide system designed for dynamic operation, high electrical efficiency and industrial integration. This represents a step change from conventional electrolysis technologies such as alkaline and PEM, which typically offer lower efficiency and limited thermal integration potential.
Dynelectro’s system incorporates several key innovations:
(i) solid oxide stacks with proven ultra-low degradation rates (less than 0.1% per 1,000 hours) based on over 23,000 hours of extended stack performance testing;
(ii) proprietary AC:DC power electronics platform that enables rapid power ramping while maintaining stable operation;
(iii) and a system architecture engineered for integration with CO2-rich gas streams, supporting the production of renewable methane and other e-fuels.
Once completed, the 1 MW system will push the performance frontier of solid oxide electrolysis and demonstrate its potential within Europe’s emerging hydrogen economy - particularly within industrial hubs, synthetic fuel production and sector-coupled fully integrated energy systems.
To enable full commercial deployment, several key enablers must be addressed. Large-scale demonstrations will be necessary to validate the technology’s economics, thermal integration and grid responsiveness at industrial scale. Strong partnerships with offtakers and system integrators, such as Yara and Fremsyn, will be critical for deploying the technology in operational environments. Access to green finance and the development of robust power-to-gas business models are also essential to support widespread adoption.
Further success will rely on a supportive regulatory framework, particularly in the areas of renewable gas certification, hydrogen blending and CO2 accounting. Continued progress on standardisation for system safety, integrated operations and performance certification will help streamline scale-up efforts.
Robust intellectual property protection will also be key to securing the competitiveness of European innovation in global markets. The progress made so far in this project highlights the potential of solid oxide electrolysis to support decarbonisation efforts and strengthen Europe’s energy independence.
