The plant has begun pilot operation of an on-site hydrogen system using the Enapter
AEM Nexus 1000
– producing hydrogen exactly where it is needed and feeding it directly into the process.

 

This is not a simple fuel switch. Heat treatment is one of the most sensitive operations in steel production. It depends on a stable, continuous energy supply.

Here, that supply is no longer external. Hydrogen is produced on site – powered by hydropower from the Dora Baltea river and a rooftop solar installation. Which means one thing: Energy input is no longer constant. It follows real renewable availability. The system has to handle that variability without impacting the process. That’s where system design becomes critical.

 

The AEM Nexus 1000 operates as a modular setup:

• multiple independent stack units
• flexible load response from 1–100%
• built-in redundancy to maintain continuous operation

So instead of relying on a single large unit, the system behaves as a distributed, controllable source of hydrogen.

This project is part of Italy’s PNRR Hydrogen Valley initiative – bringing hydrogen into existing industrial environments.

But the real shift is operational: Hydrogen is no longer supplied to the plant. It is produced, managed, and used as part of the plant’s own energy system.

That’s what industrial decarbonization looks like in practice.
