DuPont introduces first IEX for green hydrogen production

DuPont has launched AmberLite P2X110 ion exchange resin (IEX) to support the production of hydrogen from water, for the chemistry of electrolyser loops.

“Green hydrogen [is] well-positioned to reduce global carbon emissions,” said Alan Chan, Dupont Water Solutions global vice-president and general manager. “AmberLite P2X110 IEX supports the trends toward electrification and decarbonisation.”

Hydrogen can be produced by several methods from different feedstocks. Green hydrogen, which is produced from water by renewable energy-powered electrolysis, contributes to the decarbonisation of transportation, heat and energy, and as greener feedstock. Electrolysis is the process of electrically splitting the water molecules into hydrogen and oxygen gas, and while there are various types of electrolysers, they rely on high-purity water as the feedstock to produce hydrogen.

“Our portfolio can help create the high purity water that electrolysers require with ultrafiltration (UF), IEX, biofouling prevention, reverse osmosis (RO) and electro-deionisation (EDI) solutions,” said its global market leader Verónica Molina.

The AmberLite P2X110 IEX is designed to endure the thermal and chemical challenges of an electrolyser to prevent contaminant buildup in the electrolyser loop. These customised features and improved removal capacity are said to offer more service time than industry generic resins.

DuPont water technologies is said to help purify more than 50 million gallons of water every minute around the world. It offers solutions for industrial water users and water treatment municipalities with its membranes, resins and systems including nanofiltration (NF), membrane bioreactor systems (MBR), membrane aerated biofilm reactors (MABR), and closed-circuit RO (CCRO) systems.
