Electrolysers

With a capacity of 1 MW of electrical input, the new Ansaldo Green Tech electrolyser is conceived for applications with large hydrogen production volumes. The Ansaldo Green Tech 1MW electrolyser is based on last generation Anion Exchange Membrane and innovative formulation for the anodic and cathodic catalysts, which enable efficient and high-purity hydrogen production, limiting gas crossover, even at large scales.

In addition to high hydrogen production rate, the electrolyser is also designed to optimize efficiency, flexibility, safety, and reliability. 

High efficiency is ensured by an accurate selection of catalyst materials and deposition techniques, FEM based internal geometry optimization, electrolyte flow design based on CFD calculations and proper sizing of the auxiliary equipment to limit the plant energy consumption.

Safety and Reliability are ensured by an extensive monitoring of all the critical parameters that are proof of proper operating regime, which are, among others, process temperatures and pressures, output gas quality and crossover phenomena. The electrical supply is managed with all appropriate safety systems for the quickest and safest emergency actions. The unit features advanced methods to limit membrane deformation and stress, decreasing its degradation rate.
The control system allows fast and efficient transients, with full monitoring of all relevant process parameters.
