High Purity Hydrogen Generation

Proton OnSite is a global leader in hydrogen energy and innovative gas solutions. Since 1996, they have been developing and applying hydrogen technology that best meets the diverse customer’s requirements.

Proton PEM (Proton Exchange Membrane Technology) HOGEN with high purity to 99.9998%, on-demand hydrogen generators are a safe and cost effective approach to providing high purity hydrogen for industrial applications.

The advanced proton exchange membrane (PEM) electrolysis systems coupled with uncompromising attention to excellence and quality enables us to deliver, install and support gas generation units on every continent.

With more than 1200 systems installed in 56 countries, HOGEN hydrogen generators are creating value worldwide, whilst offering customers rapid payback. The HOGEN units dramatically improve plant safety by minimising storage and handling

Proton OnSite's hydrogen generation systems use a platinum catalyst and Proton Exchange Membrane (PEM) technology to split deionized water into its constituent parts.

When a DC voltage is applied to the electrolyzer, water molecules at the anode are oxidized to oxygen and protons, while electrons are released. The protons (H+ ions) pass through the PEM to the cathode where they meet electrons from the other side of the circuit, reducing to hydrogen gas. 


Proton product range includes hydrogen control systems, nitrogen generators and air generators, packaged solutions incorporating tanks, compressors and other ancillary equipment.

The generators are modular, field-upgradeable and designed to compete with delivered hydrogen anywhere in the world. A single H6 unit will supply the equivalent of one and one-half jumbo tube trailers every month. Multiple H-systems may be combined for additional capacity at no extra integration cost

The product and service pack allow us to cover a broader commercial set of markets:

  • Power plants (electric generator cooling, Nitrogen blanketing)
  • Heat treatment
  • Semiconductor
  • Laboratory
  • Nano-Technology
  • Metal Injection Molding (MIM)
