IMI’s PEM electrolyser test centre: Confidence you can see, before we install
Written By IMI Publications
January 22, 2026
Across Europe, the shift to green hydrogen is accelerating fast. For you, the engineers, project leaders and decision-makers delivering these projects, that momentum brings opportunity, but also real pressure. We understand that systems must work first time. Safety is non-negotiable. And delays or surprises are simply not an option.
That’s why success in hydrogen today isn’t just about megawatts. It’s about confidence. Confidence that your electrolyser will perform reliably, predictably and safely from day one.
Built around your project needs
At IMI, we know there’s no margin for error when an electrolyser arrives at your site. Downtime is expensive, commissioning windows are tight, and your people’s safety comes first. So, we don’t wait until installation to find out if everything works as it should.
Our dedicated PEM electrolyser test centre in Sardinia is where we prove it, before your system leaves our factory. Here, your electrolyser is fully assembled and functionally tested under conditions that closely reflect real operation. You’re invited in, side by side with our engineers, to see your system run, ask questions, and gain real assurance, not just paperwork.

Why this testing makes a difference for you
PEM electrolysers are complex systems that combine power electronics, high-pressure hydrogen, digital controls, and multiple safety layers — often connected to intermittent renewable energy sources. Small uncertainties can quickly become big problems on site.
Our test centre exists to remove those uncertainties because we test the full system:
Instrumentation and control logic.
Operating modes, start-up, shutdown and electrostatic discharge (ESD).
Hydrogen purity and pressure management.
Safety interlocks and protective systems.
By identifying and resolving issues early, we help you avoid delays, reduce commissioning effort and eliminate costly work at your facility. The result? A smoother start-up and confidence that your electrolyser will perform exactly as you expect it to.
Faster throughput with a focus on quality
Our facility is designed for scale, with the capacity to test up to 4 PEM electrolysers simultaneously. Each week follows a continuous, efficient flow:
One system is being installed.
One is undergoing detailed checks and pressure testing.
One is completing factory acceptance testing with you.
One is being dismantled and prepared for shipment.
This approach allows us to test one electrolyser every week, keeping pace with growing demand across markets in Italy, Germany, Lithuania, Portugal and the United Kingdom, and while maintaining the same high standards for every project.
Transparency, collaboration and trust
We designed the test centre with one goal in mind: to support you. By involving you early, we turn testing into a collaborative experience rather than a final hurdle. You gain direct insight into your system, a clear understanding of how it performs, and a trusted relationship with the engineers who built it.
That transparency builds trust. And trust builds confidence.
Confidence that gives you an edge
As green hydrogen moves from pilot projects to large-scale deployment, the winners will be those who deliver reliably, safely and on schedule. Confidence in system performance is becoming a competitive advantage.
With confirmed orders across multiple countries and delivery schedules stretching into 2027, predictability matters more than ever. Our PEM electrolyser test centre plays a key role in delivering it, ensuring every system is validated, proven and ready for installation.
More than a test facility, it’s a promise: that when your electrolyser arrives on site, it’s ready to perform. Learn more about IMI VIVO or contact us for a site visit.
