Electrolysers

The Ansaldo Green Tech AEM electrolyser portfolio, available in 1 MW and 6 MW configurations, is designed for industrial‑scale hydrogen production, combining high efficiency, operational flexibility and long‑term reliability. Both systems adopt next‑generation Anion Exchange Membrane technology, innovative catalysts and FEM/CFD‑optimized internal geometries that ensure stable, high‑purity hydrogen generation with minimal gas crossover and reduced membrane stress.

Efficiency is maximized through optimized electrochemical cell design, accurate materials selection and proper sizing of auxiliary equipment to minimize overall energy consumption. Continuous monitoring of key process parameters—such as temperatures, pressures, gas purity and crossover phenomena—ensures safe and reliable operation, supported by advanced electrical protection systems for rapid emergency response. Mechanical and thermal strategies contribute to limiting membrane deformation and extending component lifetime. Additional optimizations include reduced dependency on critical raw materials, low‑molarity electrolytes, minimized water consumption and excellent partial‑load performance.

The electrolysers offer fast and efficient load transitions and are engineered to operate with variable power input, enabling seamless integration with intermittent renewable sources such as solar and wind. Both 1 MW and 6 MW units can be installed in greenfield or brownfield sites and support remote monitoring, unmanned operation and automated control through PLC/SCADA systems. Predictive diagnostics further enhance performance and reduce maintenance requirements.

The standard 1 MW system is delivered as an outdoor containerized module and can be configured into multi‑MW architectures.

The 6 MW solution builds on this platform by integrating multiple 1 MW stacks, auxiliary subsystems and dedicated power conversion units on a modular process skid. This approach enables scalable configurations beyond 20 MW, making the system suitable for large‑scale hydrogen production.

Additional optimizations include reduced dependency on critical raw materials, low‑molarity electrolytes, minimized water consumption and excellent partial‑load performance.

Both models are designed for high availability, with minimal maintenance needs and dedicated service packages supported by remote monitoring and diagnostic tools.
