VONEN Hydrogen Purification and Dehumidification Systems

VONEN Hydrogen Purification and Dehumidification Systems

The VONEN H2-PRF / MHS Hydrogen Purification and Dehumidification System Allows continuous purification, storage and use of hydrogen gas. The system is based on the use of the H2-MHS VONEN hydrogen storages’ metal hydride, which only absorbs hydrogen and rejects most contaminants like oxygen, water and nitrogen. These contaminants are purged out from the H₂ storage vessel.

VONEN H₂ PRF/MHS

• H₂ purity (99.99973% according to our latest tests) complies with the SAE standard for Hydrogen Fuel Quality for Fuel Cell Vehicles;
• Low storage pressure – only 2-4 bar;
• Ideal technical solution for hydrogen dehumidification after water electrolysis;

Since only hydrogen is stored in the metal hydride, the H₂ gas purity at the outlet is above 99.999% (99.99973%) in our latest tests).
Since the VONEN H2-MHS storage units do not suffer from self-discharge, hydrogen can, if necessary also be stored in the purification system for years without any loss of energy.
