Dynamic Electrolyser Unit – 250 kW
Our 250-kW solid oxide electrolyser (SOE) is a high-efficiency system designed for scalable clean hydrogen production. Operating at high temperature, SOE technology requires less electricity than conventional electrolysis technologies, making it one of the most energy-efficient solutions available.

The 250 kW Dynelectro SOEC Dynamic Electrolyser System is a solid oxide electrolyser (SOE) module engineered for industrial-scale hydrogen production. Built on proprietary SOE+ technology, it achieves a 500 % extended stack lifetime through dynamic AC/DC operation and a 20 % reduction in the Levelized Cost of Hydrogen (LCOH).
Engineered with precision
Each 1 MW module is designed for seamless integration into existing industrial plants and scalable installation up to multi-MW configurations.
Documented performance
Tested for 25,000 hours at ultra-low degradation rates (<0.2 % per 1,000 h), Dynelectro’s technology delivers proven performance, long-term cost advantages, and a scalable pathway to net-zero industrial operations.
- Low stack degradation – enable 5x SOEC stack lifetime extension due to alternating AC/DC operation – <0.2% stack degradation per 1,000 hours
- Increase H2 output – 50% higher hydrogen output per power unit vs. Alkaline / PEM electrolysis
- Reduced cost – 20% lower LCOH vs. other PtX technologies
- Dynamic operation / Variable Load Following – ideal for fluctuating renewable input
- Ancillary Grid Service offering possible – flexible operation enables availability for FFR / FCR / FRR capacity offerings
Applications
Hydrogen production for:
- Synthetic fuel synthesis (e-fuels, methanol, ammonia)
- Industrial process integration (chemicals, steel, refineries)
- Distributed heat and power applications
