The Alpha 50 plant is a skid-mounted, prefabricated electrolyser system designed to minimise construction and civil works.

Based on ITM’s PEM Trident stack technology, the system includes the entire balance-of-plant (BOP) and requires only ‘tap water’ and electricity to operate.

The UK-based manufacturer said the plant’s “compact footprint” would allow it to be integrated into larger, multi-hundred-megawatt systems.

ITM said the €50m “full-scope” price covers the complete plant – including water purification, all electrolyser skids, BOP, and control systems – but excludes site-specific costs such as shipping, installation, and civil works.

The stated price of around $1,166/kW places it highly competitively against Western systems currently being marketed at $2,000–$2,500/kW, according to some reports.

CEO Dennis Schulz told H2 View the Alpha 50 would outperform comparable PEM, alkaline, and even Chinese systems on total installed cost.

ITM will produce the core skid including stacks at its factory in Sheffield, while the remaining BOP skids will be assembled in selected module yards, depending on project location. “This is a proven approach in the EPC world,” Schulz said.

The plant’s skidded modularity is based on a system allowing each 40ft skid to be easily put together on site, H2 View was told.

Furthermore, the plant can be scaled up or down in 10MW increments, allowing the firm to meet a range of project requirements.

“Alpha 50 is optimised for maximum hydrogen output and maximum plant availability,” Schulz said, explaining the plant features duplicates of failure-prone components like pumps.

“Critical components are redundantly designed so that if something fails, the plant will keep running while you can exchange certain parts.”

Such modular, factory-built approaches are increasingly being adopted across the sector as OEMs look to reduce project complexity and costs.

Other electrolyser OEMs like Longi, Electric Hydrogen, and Nel have launched large-scale standardised plants aimed at cutting EPC costs. However, this is the first with a public price tag attached.

It comes as the company’s second public price reveal, after it launched its 5MW containerised system last May at a price of €5m ($5.82m) – around $1,166/kW.

Schulz told H2 View the company’s desire to break industry norms in revealing pricing was a sign of its confidence in both its competitiveness and its delivery capability.

And he believes it will help industrial customers and developers break the final investment decision (FID) barrier.

“I still see a lot of projects that are struggling to take FID,” he told H2 View. “And if we can give them a route to a more competitive solution, this will unlock many of them.”
