Hydrogen Fueling Systems

Proton OnSite' patented proton exchange membrane (PEM) electrolysis technology can provide the solution to meet global hydrogen needs.

Hydrogen is more than a low carbon fuel - it is a zero carbon fuel made from a dependable and readily available source: water. When generated using renewable energy sources, hydrogen fuel holds the promise of zero emissions as well as energy independence and security in the transportation sector.

Our FuelGen® hydrogen fueling system is a fully-integrated, packaged electrolysis system that produces medium pressure, high purity hydrogen -H2Go®-from water and electricity. The system includes the following components and features:

  • Electrolyzer cell stacks
  • Outdoor-rated enclosure with shrouds
  • Integrated vent stack with automatic drain trap
  • Support and safety systems for regulating electrolyzing operations
  • On-board feed water purification system
  • Automated tank-topping option
  • Power conservation during stand-by
  • Remote monitoring
