Innovation Through Hydrogen Purification

Removing impurities at the source

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. 

Regardless of the power source, electrolysis produces hydrogen-rich gases that contain moisture and traces of oxygen and nitrogen. Honeywell UOP purification technologies effectively increase hydrogen product concentration to prepare it for transportation and use.

Honeywell UOP’s Hydrogen Temperature Swing Adsorption (TSA) technology is a commercially proven, cost-effective solution to purify hydrogen from water electrolysis. With flexible turndown and operations, the Hydrogen TSA is equipped to handle intermittent power, which can come from renewable energy sources like solar or wind. Honeywell UOP’s Hydrogen TSA is most appropriate for gas streams containing oxygen and water. 

Honeywell 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
