Power to Hydrogen (P2H2), a developer of anion exchange membrane (AEM) electrolyzer systems, has begun commercial green hydrogen production at the NextGen District of the Port of Antwerp-Bruges, Belgium.

The 500 kW system, built from two 250 kW stacks and delivered to the site in August 2026, is described by P2H2 as the first commercial deployment of 250 kW AEM stacks – more than ten times larger than the stacks used in conventional AEM systems, which typically range from 2 kW to 25 kW.

Now operational, the system will initially produce up to 70 tonnes of green hydrogen per year. Regional gas supplier Holthausen is named as the primary offtaker, with additional industrial and mobility customers in the area. The system’s 10–100% operating range allows it to follow Belgium’s day-ahead electricity prices, ramping up when renewable power is cheapest.

P2H2 said it plans to use operational data from the Antwerp deployment to support a move toward larger platforms, including multi-megawatt systems. A second commercial order – a 500 kW dual-250 kW stack system supporting the EU-funded PYROCO2 green-chemicals project – will be delivered to Norwegian research institute SINTEF later in 2026. The Antwerp project has received partial support from the European Regional Development Fund and the Flemish innovation and entrepreneurship fund administered by VLAIO, with total EU and Flemish investment reported at close to €900,000.

Paul Matter, Chief Executive Officer of Power to Hydrogen, said: “Bringing this system online in one of Europe’s most demanding industrial environments is how we answer the skepticism around AEM: not with claims, but with hardware on the ground. Antwerp is the first step in showing that AEM can be real, durable and repeatable, and that it can help bring down the cost of green hydrogen where it matters most.”

Carl Holthausen, Director and CTO of Holthausen, said: “We have been selling hydrogen long enough to know that the demand for zero-emission hydrogen is real. What continues to hold the market back is access to reliable supply at a price customers can plan around. A dedicated local source gives us the confidence to quote our customers against a known cost and dependable volume, rather than being exposed to changing market conditions.”
