Innovation through hydrogen purification
An alternative to producing hydrogen is through the electrolysis of water. If the power source for the electrolysis is renewable electricity from wind or solar power, then it can be classified as “green hydrogen” producing significantly fewer emissions overall.
Removing impurities at the source
Regardless of the power source, electrolysis produces hydrogen-rich gases that contain moisture and traces of oxygen and nitrogen. Honeywell Technologies UOP purification technologies effectively increase hydrogen product concentration to prepare it for transportation and use.

Polybed™ Pressure Swing Adsorption (PSA)
Honeywell Technologies UOP’s Polybed™ Pressure Swing Adsorption (PSA) technology can be used to purify hydrogen from more complex gas streams. The Polybed PSA is commercially proven, leveraging technology developed by UOP in 1966.
Honeywell technologies purification process
Green hydrogen is produced through water electrolysis using renewable power. It contains impurities that need to be separated to obtain a cleaner byproduct. Green H2 purification takes care of the impurities to make it on-spec.
