Containerized PEM Hydrogen Generators: 246 to 492 Nm³/h

In sites where plant space is at a premium, customers may choose to install their electrolyzers outside. In other cases, customers may prefer to configure an electrolyzer for a more turnkey operation. To fulfill those requirements, Nel Hydrogen recommends containerization.

The M Series MC250 and MC500 units are supplied and placed in free-standing containers for ultimate flexibility.

Containerized M Series electrolyzers can generate up to 492 Nm3/hour of hydrogen gas at 99.9995% purity on-demand. Common applications include industrial process gas, renewable energy storage, and hydrogen fueling.

Features

  • Pure hydrogen at process pressure – up to 30 barg (435 psig) hydrogen and 99.9995% purity
  • Cost-effective hydrogen supply – tracks electric costs
  • Increased safety – caustic chemicals are not used
  • Virtually zero stored hydrogen – removes the hazard of flooding the space
  • Large capacity with minimal footprint – only a fraction of space needed compared to storing large volumes of gas or liquid hydrogen
  • Dependable supply of hydrogen—field-proven reliability
  • Containerized design – versatile plant configurations
  • Automated – safe operation without manual involvement
