Nel Hydrogen is a world leader in large-scale electrolszers. Its A Series units provide for smooth capacity upsizing from medium to large-scale hydrogen plants based on water electrolysis technology.
Nel Hydrogen’s expertise in large-scale plants is demonstrated through historical plants surpassing 30,000 Nm³/h, as well as the latest installation of new plants with an energy capacity of over 60 MW.
The A Series, which features the most energy-efficient electrolyzers in the world, features a cell stack power consumption down to 3.8 kWh/Nm3 of hydrogen gas generated, up to 2.2 MW per stack.
The A Series electrolyzers can generate up to 3,880 Nm3/hour of hydrogen or just above 8 ton per day. Users can containerize this powerful system, which has one of the world’s smallest footprints for high-capacity electrolyzer plants at 200 barg.
Features
- Pure hydrogen at process pressure – up to 200 barg (2,900 psig) hydrogen and 99.99 to 99.999% purity
- Cost-effective hydrogen supply – tracks electric costs
- Virtually zero stored hydrogen – removes the hazard of flooding the space
- Large capacity with minimal footprint – only a fraction of space needed compared to storing large volumes of gas or liquid hydrogen
- Dependable supply of hydrogen – field-proven reliability
- Modular skid-based design – versatile plant configurations
- Automated – safe operation without manual involvement
- Containerization is available – easy installation
