Power to Hydrogen (P2H2), a developer of anion exchange membrane (AEM) electrolyzer systems, today began commercial green hydrogen production at the NextGen District of the Port of Antwerp-Bruges. The 500 kW system, built from two 250 kW stacks, is the first commercial deployment of 250 kW AEM stacks.
Now operational, the system will initially produce up to 70 tonnes of green hydrogen per year for regional gas supplier Holthausen and other customers in the area. The hydrogen will be used mainly for mobility customers with other industrial use-cases as an additional potential offtake. Local hydrogen production strengthens European energy resilience and gives the region's fuels, chemicals, and mobility sectors a cost-effective lower-carbon hydrogen supply.
Because electricity is the largest cost in green hydrogen production, P2H2's systems are designed to produce when renewable power is cheapest. The Antwerp system's 10–100% operating range lets it follow Belgium's day-ahead prices, ramping up when power is cheap and ramping down when it is not. As a result, the Antwerp system is able to deliver locally-produced hydrogen that is cost-competitive to other hydrogen sources.
The commissioning comes as P2H2 prepares data from the Antwerp deployment to support a move toward larger platforms, including multi-MW systems. A second commercial order for 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 this year.
The deployment is a milestone in moving AEM electrolysis from the laboratory into industrial operation. AEM has long demonstrated PEM-like performance at a cost closer to alkaline, but durability has remained a key barrier. P2H2 has solved the core durability problem.
P2H2's proprietary hybrid AEM-alkaline cell design places an alkaline separator between the membrane and the oxygen-producing electrode, which protects the membrane and extends its life. The system uses low-cost, iridium-free catalysts, a simpler balance of plant than conventional alkaline (including a single electrolyte loop), and mechanical membrane support that enables 30 bar output pressure with minimal hydrogen crossover, cutting downstream compression.
On September 8, P2H2 announced the results of a 1,250-hour pilot with Repsol, one of Europe's leading energy companies, which measured irreversible degradation of about 2 mV/kHr — 5–10x better than the AEM targets published by the US Department of Energy and the EU Clean Hydrogen Partnership — and projected stack life beyond 50,000 hours. Using Repsol-specific inputs and the U.S. Department of Energy's H2A-Lite analysis framework, P2H2 projects a levelized cost of hydrogen of approximately €3.86/kg, a ~16% reduction versus incumbent electrolyzer technologies.
The Antwerp project is supported in part by the European Regional Development Fund (ERDF/EFRO) and the Flemish innovation and entrepreneurship fund administered by VLAIO.
Power to Hydrogen (P2H2) makes industrial-scale electrolyzer systems that produce green hydrogen from renewable electricity. Its anion exchange membrane (AEM) platform is designed to deliver dynamic performance — including sub-50-millisecond load response and 30 bar hydrogen output — using a lower-cost, iridium-free materials pathway that avoids the scarce inputs that have historically constrained electrolyzers at scale. P2H2's systems are engineered for direct integration with variable renewable power and are designed to scale to repeatable multi-megawatt deployments, with multiple commercial projects underway globally. P2H2 is backed by AEP, EDP, E.ON, ESB, Air Liquide, JERA and Asahi Kasei, and is a 2026 World Economic Forum Technology Pioneer.
