Produce your hydrogen on-site, on demand, according to your specifications

Thanks to the fast dynamic response of our electrolyzers, the on-site hydrogen production is guaranteed, ensuring our customer the complete control of their processes and costs.

Piel and McLyzer: two complementary ranges of electrolyzers to cover all your needs

McPhy proposes the widest range of electrolyzers on the market.
From 0,4 to 800 Nm3/h, and above thanks to multi-MW designs, over a range of pressures from 1 to 30 bar, our electrolyzers are designed to cover all your needs in terms of flow rate, pressure and purity; from light applications (f.e.: jewellery) to multi MW designs (f.e.: heavy transportation or heavy industry).

Hydrogen production by alkaline electrolysis:
the most mature technology on the market

With more than 1.000  installations, our equipment is recognized among the market leaders

Among the various hydrogen generation methods, McPhy has specialized in hydrogen production by alkaline electrolysis, which offers the following advantages:


  • Reliability: an industrialized, mature process
  • Rapid response time / Dynamic response: perfectly adapted to couple with renewable energies, for the continuous automated adaptation to fluctuating electricity
  • High-pressure production: up to 30 bar
  • High energy efficiency
  • Robustness: up to 80.000 hours of life for the stack
  • Performances:
    Low electricity consumption: 4.5 kWh/Nm3 or 50 kWh/kg at the level of the stack at rated speed (100 %)
    0 to 100% in less than 30 seconds and 100 to 0% in less than 5 seconds
    Potential to deliver up to 130% of rated speed
  • Plug and play system: easy installation and function for an automatic operation and a low maintenance
  • Compact: integration facilitated to your infrastructure
  • Economic competitiveness
  • Low carbon footprint: in particular for coupling configurations with renewable energies
  • Supervision and continual improvement management


Augmented McLyzer, 

  • A modularized and scalable architecture: 20, 100 MW and more
  • A real technological breakthrough, thanks to a unique combination between our high-pressure alkaline electrolysis technology (30 bar) and the advanced electrodes of De Nora, which makes possible to:
    Double the quantity of hydrogen produced
    With the same stack size (reduced footprint)
    And the same specific energy consumption
    High energy efficiency
    Drastic improvement of competitiveness.
  • Easy to install: stacks and BOP are manufactured by McPhy, on-site assembly is limited to interconnections


All of our products bear the CE marking and McPhy relies on organizations such as TüV for certifications.
