Our solutions
Modular AEM electrolysis for on-site hydrogen production – from the H2i-AEM-Core and the H2i-POWERPACK to the ready-to-install H2iVE-SKID.
One technology, three levels: from the H2i-AEM-Core to the power unit to the ready-to-install platform – each level built for series production and easy integration.
H2i-AEM-Core – the technology
H2i-AEM-Core
The heart of our technology: AEM water electrolysis with around 70% voltage efficiency (LHV) – iridium-free, with PFAS-free membrane and seals. Designed for automated series production to automotive standards and for refurbishment at end of life.
H2i-POWERPACK – the power unit
H2i-POWERPACK
Four H2i-AEM-Cores on one manifold block: the H2i-POWERPACK delivers 26 kg of green hydrogen per day at up to 60 kW – as the core of the H2iVE-SKID. Additional power ratings are in development.
H2iVOLT – the interface for real-time condition monitoring of every H2i-AEM-Core and the basis for adaptive load distribution.
H2iVE – system architecture meets operating strategy
H2iVE
H2iVE combines our modular system architecture with our unique operating strategy: the load is adaptively distributed across six independent modules.
The result: availability by design – 520 kg/d even during module service – and minimized levelized cost of hydrogen over the entire lifetime.
H2iVE-SKID – the ready-to-install platform
H2iVE-SKID
520 kg of green hydrogen per day from a single 20-ft platform, for container or indoor installation. 24 H2i-POWERPACKs in six independent modules deliver 1.25 MW of electrolysis power and hydrogen at 30 bar(g) and 99.9% purity (3.0), DeOxo-ready.
Integrated KOH loop, hydrogen dryer, safety systems and a central utility unit with defined interfaces for water, heat, H2, O2 and purge gas. Power electronics and controls are included in the scope of supply and installed separately.

FAQ
More about our solutions
When will H2i products be available?
Our technology is being validated on our own DemoC3 test facility. From 2027, we will install the first reference plants at customer sites.
Which electrolyte is used?
Dilute potassium hydroxide. The closed KOH loop is fully integrated into the H2iVE-SKID.
What water quality does an H2iVE-SKID require?
Tap water treated by reverse osmosis, or deionized water available on site. Demand at rated load: approx. 280 kg/h of tap water or 194 l/h of purified water.
What interfaces does an H2iVE-SKID provide?
The H2iVE-SKID is designed for container and indoor installation. Standardized connections for fresh water, heat recovery (supply/return, 50 °C), hydrogen, oxygen and purge gas. Electrical: 400 V AC / 50 Hz, 1.5 MVA. Power electronics and controls use common industrial standards and integrate into higher-level control systems.
Can an H2iVE-SKID be combined with other electrolysis technologies?
Yes. The KOH loop is fully integrated into the H2iVE-SKID; only fresh water, a cooling medium and a 400 V AC connection are required. This allows the SKID to complement existing alkaline or PEM plants, e.g. for dynamic load shares.
How dynamically can an H2iVE-SKID operate?
Load range 10–100% (24–240 Nm³/h), load changes of up to 5%/s during operation. H2iVE load distribution across six independent modules keeps low operating points efficient.
How does the system scale beyond 1.25 MW?
Multiple H2iVE-SKIDs are combined into a multi-SKID plant (n × 1.25 MW). Water treatment, gas purification and nitrogen supply are shared, and H2iVE load distribution runs across all modules.
How are service and maintenance handled?
Modules are replaced individually while the remaining modules continue to produce. The H2i-AEM-Cores are designed for refurbishment.
What gas purity is achieved?
99.9% (3.0) at 30 bar(g). Higher purities are available as an option via a central DeOxo stage, not included in the H2iVE-SKID scope of supply.
