SOE+ 20 MW

Overview

The SOE+ 20 MW is a modular industrial Solid Oxide Electrolyser System designed for large-scale hydrogen production. Powered by Dynelectro’s proprietary AC:DC architecture, it delivers industry-leading efficiency, ultra-low degradation and dynamic operation in a scalable containerised platform. Enabling industry-leading SOEC stack lifetimes of 7–10 years under industrial operating conditions.

Engineered with precision

Each 20 MW system is designed for seamless integration into existing industrial plants and scalable installation for multi-MW configurations.

Documented performance

• Low stack degradation – enable 5x SOEC stack lifetime extension due to alternating AC/DC operation – <0.05% 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
