Featured Product Technologies
Regardless of the electrolyzer type, Parker’s Water Purification technologies are essential to protect the process, to maintain efficiency and to purify the hydrogen gas stream to the high standards required.
Demineralizer System
Parker’s demineralizer technology is a combination of Reverse Osmosis and Electro-Deionization capable of producing demineralized water up to 18 MΩ-cm from any feed water source.
Refinement Loop Mixed Bed Resin System
Electrolyzer Water Filtration
The two most established processes for green hydrogen production are alkaline water electrolysis and proton exchange membrane (PEM) electrolysis. Electrolysis involves using an electrical current to break down the water molecule into oxygen and hydrogen by electrodes. Water is the feedstock for green hydrogen production, and it must be treated to ultrapure quality. Inadequate water treatment can jeopardize the operation and damage the electrolyzer. Parker’s wide range of water purification solutions provide innovative ways to filter, purify, discharge, recapture, recondition or reuse industrial and process water. Our proven industrial and customized membrane and filtration systems blend superior performance with full compliance to deliver optimum reliability in pretested, packaged skids or turnkey containerized solutions for electrolyzer applications.
Hydrogen Production by PEM Electrolysis of Water
In green hydrogen production, electrolysis is used to break down water into its individual elements; hydrogen (H2) which is compressed and sent to storage, and oxygen (O2) which is either also stored or vented to the atmosphere. There are several different electrolysers that can be used. The one shown here highlghts Proton Exchange Membrane (PEM) electrolysers which use a solid polymer electrolyte that only allows hydrogen ions (protons) to pass through to form hydrogen gas on the cathode side.
