PEM electrolyzers

• 1-10 MW capacity, cascadable

• 200 - 2000 Nm3/h H2

• Extremely small footprint

• Ready for connection (grid, water)

• For all environments

• Ready for operation

Sustainable. Durable: Green Electrolyzer

The plants are based on cascadable PEM stacks, each of which generates up to 200 Nm³/h of hydrogen. The PEM stacks can be regulated to between 10 and 100 percent of the nominal power and quickly adapted to load changes.

The systems can be powered up from standstill to full load operation (nominal power) within a very short time. Similarly, the PEM electrolyzers can be switched off from full-load operation or switched to stand-by operation without a time-consuming shutdown.

Thanks to their modular design, the Green Electrolyzers can be coupled to produce a total output of up to 100 MW. The plants are also characterized by the fact that they produce an output pressure of up to 40 bar for the hydrogen. This is the most economical prerequisite for further compression for H2 refueling purposes.

The PEM electrolyzers are available as “indoor” and “outdoor” versions, are completely assembled at the factory by default, and ready for operation in any environment. This allows customer-specific plants to be planned and implemented efficiently.

Flexible &

The Green Electrolyzers are individually designed according to customer-specific requirements regarding pressure ranges, flow rates and gas quality. An intensive sharing of experience with end customers regarding the operation of our plants is reflected in the development.

Hence, our electrolyzers are known for maximum availability, low investment and operating costs, low maintenance and servicing costs, as well as a sophisticated control and monitoring concept for fully automated production without operating personnel.

  • Safety:
    Physical separation of H2 and O2 production, in compliance with the ATEX directive.
  • Efficiency:
    Low maintenance, high system efficiency, < 5 kWh / Nm³ H2.
  • Adjustment range:
    10% to 100% of nominal power
  • Reliability:
    Designed for more than 80,000 operating hours for electrolysis.
  • Environmentally friendly:
    In accordance with environmental and emission standards – no hazardous substances.
