Containerized Alkaline Hydrogen Generators: 150 to 300 Nm³/h

Nel Hydrogen’s AC150 and AC300 containerized alkaline hydrogen generators wrap electrolyzer technology in containers, enabling quick and robust outdoor or indoor installations.

The A Series electrolyzers feature a cell stack power consumption down to 3.8 kWh/Nm3 of hydrogen gas produced, up to 2.2 MW per stack. They can generate up to 3,880 Nm3/hour of hydrogen or just above 8 ton per day. This advanced, compact design offers an excellent turnkey solution, delivering an output pressure of 30 barg/200 barg (435 psig/2,900 psig).

Common applications include on-site hydrogen gas supply for industrial processes and fueling stations.

Features

  • Pure hydrogen at process pressure—up to 200 barg (2,900 psig) hydrogen and 99.99 to 99.999% purity
  • Cost-effective hydrogen supply – tracks electric costs
  • 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
