New generation of pressurized alkaline electrolysis for large-scale platforms (multi-MW/GW)

McPhy is supporting the transition of the industry, mobility and energy sectors towards a low-carbon economy, allowing customers to move away from fossil energies by mass production of zero-carbon hydrogen at competitive prices. To this purpose, as a true breakthrough technology, our “Augmented McLyzer” electrolyzers combine the reliability and the maturity of pressurized 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.

As the most mature hydrogen generation process, a robust and proven technology, showing the longest track record on an industrial basis, alkaline electrolysis appears to be the cornerstone required for the mass production of zero-carbon hydrogen and the decarbonation of the markets.

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

This technology has been selected to equip the “Djewels” project: the largest zero-carbon hydrogen production unit, first on this scale (20 MW), to be implemented in Europe.

McPhy launched in 2018 its breakthrough “Augmented McLyzer” technology, a unique combination of our core expertise of high-pressure alkaline electrolysis and the integration of 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.

The solution is fully modularized and based on a 4 MW module design (McLyzer 800-30), used as a “building block”. Our systems produce zero-carbon hydrogen directly at 30 bar, and are designed to scale up with your operating rhythm.

Djewels project

Our 20 MW Augmented McLyzer platform selected to equip this pioneering project in Europe! Zero-carbon hydrogen will be used in a chemical process to produce e-methanol. With 3,000 tons of H2 produced per year and up to 27,000 tons of CO2 emissions abated, Djewels is a true stepping-stone for the future upscaling of clean hydrogen production via electrolysis from renewables [Read the release]

Focus on the technology

Augmented McLyzer, a breakthrough pressurized alkaline electrolysis technology

  • INNOVATIVE TECHNOLOGY
    A real technological breakthrough, thanks to a unique combination between our high-pressure alkaline electrolysis technology (30 bar, directly at process pressure) and the advanced high current density electrodes co-developed with 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
    Very rapid dynamic response time, offering the required flexibility for the power-market led operation, suitable with primary leveling market requirements, pointing towards a totally optimized investment
  • ECONOMIC COMPETITIVENESS
    Best TCO (Total Cost of Ownership) in its category, with a delivery pressure (30 bar) that significantly decreases the energy demand for further compression
    “Bigger scale, lower costs”: the extensive roll-out of hydrogen applications will result in mass marketing of the electrolysis technology and a drastic reduction in costs
  • SCALABILITY
    A modularized and scalable architecture based on a 4 MW core module
    Industrial size: 20 MW (and more: 100 MW up to GW) units already on the market
    Associated with a manufacturing plan of “scaling up” (100 MW +) to meet the huge needs of the Industry sector in the medium and long term
  • ROBUSTNESS
    An angle stone for industrial players
  • SAFETY
    Consistent model simulations to bring the quality and safety of our equipment to a level never achieved
  • 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

Cluster 20 MW | Hydrogen production: 4,000 Nm3/h, compact footprint  < 900m2

Application areas

This multi-MW range is specifically designed towards the large-scale decarbonation of the industry, mobility & energy sectors:

  • 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?

“CCU”

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!
