A Series

Atmospheric Alkaline Electrolyser

485 Nm³/h | 1,047kg/day

Elevate your industrial processes with one of the world's most energy-efficient electrolysers, designed to meet the demands of the future.
  • Unprecedented Efficiency: The A Series boasts a remarkable cell stack power consumption as low as 4.5 kWh/Nm³, setting a new standard for energy efficiency in hydrogen production.
  • Strategic Product Lineup: Responding to market dynamics, Nel has streamlined its product offerings. The A150 and A300 have been retired, leaving the powerhouse A485 as the sole building block for large-scale installations.
  • Scalability Redefined: Combine multiple A485 electrolysers to meet any required production capacity. For instance, the A4000 seamlessly integrates 8 electrolysers, achieving an impressive production capacity of 3880 Nm³/h of hydrogen.
  • Unmatched Safety Standards: Operating at atmospheric pressure, the A Series ensures an exceptionally safe environment. Leakages are highly unlikely, and in the rare case of a leak, the volumes are minimal.
  • Comprehensive System Design: Downstream of gas separator modules, our technology ensures thorough cleaning and cooling of hydrogen before delivery. The gas holder maintains a slight overpressure, serving as a buffer for the compressor.
  • Complete Solution Package: Nel provides a standard package, including the process and safety control system for the atmospheric part of your hydrogen production system.
  Your hydrogen production journey deserves the expertise of Nel. While we deliver the standard atmospheric components, our extensive knowledge in hydrogen system design positions us to offer unparalleled engineering support for your specific needs. Nel: Proven technology, trusted partner.

PSM Series

PEM Electrolyser – PSM Series

2,020 Nm³/h | 4,300 kg/day

The PSM is a proton exchange membrane (PEM) based water electrolyser module that integrates eight 1.25 MW cell stacks to generate hydrogen from deionized (DI) water and four DC electrical power inputs. The PSM includes the PEM cell stacks, associated piping, DC power connections, and related critical monitoring instrumentation.

The PSM employs a modular approach to hydrogen production designed to offer guaranteed, repeatable performance per module to provide a cost-effective solution for hydrogen production at all scales.
  • Plug and play containerized electrolyser stack module for easy plant integration
  • Site ready design eliminates the need for a building and reduces construction cost
  • Pre-integrated stacks reduce installation time and risk
  • Instrumentation for critical process and safety monitoring included in package
  • Assembled and pre-tested at factory to assure quality control

M Series Containerized

Containerized PEM Electrolyser

492 Nm³/h | 1,062 kg/day

In situations where plant space is at a premium, customers may want to site their electrolysers outside. At other times customers may want to configure an electrolyser for a more turnkey operation. To satisfy those needs, we suggest containerization. MC electrolysers deliver the M Series platform in a containerized form for easy outdoor installations. The M Series PEM Technology makes for a reliable and turnkey solution with minimal maintenance. Typical applications include renewable energy storage, industrial process gas, and hydrogen fueling.
