New generation alkaline electrolysis for large-scale platforms (multi-MW)

A true breakthrough technology, our “Augmented McLyzer” electrolyzers combine the reliability and the maturity of alkaline technology with great flexibility. They are integrated into our large-scale (multi-MW) electrolysis platforms, specifically designed for use in the industry and heavy-duty transport sectors.

Augmented McLyzer: 20, 100 MW and more (GW) architectures

New generation alkaline electrolysis

Based on a 4 MW module design (McLyzer 800-30), producing hydrogen directly at 30 bar, our systems are created to scale up with your operating rhythm.
They use new generation electrodes with high current density (doubled compared to standard electrodes) that significantly increase the performance of our equipment, all within a compact design.

Focus on the technology

Augmented McLyzer

  • A modularized and scalable architecture based on a 4 MW ELY module: 20, 100 MW and more (GW)
  • 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 fuel cell 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

Our 20 MW cluster:

  • 30 bar: high pressure production
  • Nominal H2 capacity: 4,000 Nm3/h
  • Fast dynamic response time
  • High energy efficiency
  • A compact footprint < 900 m2
  • Nominal O2 capacity: 2,000 Nm3/h

Our 100 MW platform:

  • 25 modules of 4 MW
  • Based on the same architecture as the 20 MW clusters
  • A total footprint below 4,500 m2
  • 20,000 Nm3/h of hydrogen, more than 42 tons per day
  • 30 bar: high pressure production
  • Fast dynamic response time
  • High energy efficiency
  • 10,000 Nm3/h of by-product O2, 342 tons per day

Application areas

This multi-MW range is specifically designed to address the large-scale (and decarbonized!) industrial and mobility needs.

  • Petrol and gas refineries: fuel desulfurization, e-fuels, etc.
  • Chemical processing: methanol, synthesis of ammonia for fertilizers, etc.
  • And also: steel mills, coal-fired plants, thermal power stations (cooling system for alternators), metallurgy, glass production, electronic components, etc.
  • Large-capacity hydrogen stations : not only for large captive fleets (utility vehicles or public stations for passenger cars), but also to refill heavy-duty transport modes (such as buses, trucks, trains, boats, etc.).

Did you know?


Thanks to “Carbon-Capture Utilization”, even industrial pollutant emissions can be valorized. Captured before being ejected into the atmosphere, then added to hydrogen, the CO2 emissions help to create synthetic molecules that can be applied to new uses: methanol, biodiesel, e-fuel, and more!
