US materials firm DuPont has announced the launch of its first product dedicated to the production of green hydrogen – the DuPont AmberLite P2X110 ion exchange resin. To support the production of hydrogen from water, this newly available ion exchange resin is designed for the unique chemistry of electrolyser loops.
Hydrogen can be produced by several methods from different feedstocks. Green hydrogen, which is produced from water by renewable energy-powered electrolysis, can play several major roles in the energy transformation—contributing 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 all rely on high-purity water as the feedstock to produce hydrogen.
“Our multi-tech portfolio can help create the high-purity water that electrolysers require with our ultrafiltration, ion exchange, biofouling prevention, reverse osmosis and electrodeionisation solutions,” said Verónica Garcia Molina, Global Market Leader, Industrial Water & Energy, DuPont Water Solutions.
Designed to endure the thermal and chemical challenges presented in an electrolyser, the resin’s recipe offers durable and reliable water quality that helps prevent contaminant build-up in the electrolyser loop. These customised features, and improved removal capacity, present a differentiated option for electrolysers with more service time than industry generic resins.
DuPont’s water technologies help purify more than 50 million gallons of water every minute around the world, enable water reuse and recycling, desalination, and the safe access of both ground and surface water.
DuPont offers solutions to a variety of water and sustainability challenges faced by industrial water users and water treatment municipalities through a broad portfolio of membranes, resins and systems (including reverse osmosis (RO) membranes, ion exchange resins (IEX), ultrafiltration (UF), electrodeionisation (EDI), nanofiltration (NF), membrane bioreactor systems (MBR), membrane aerated biofilm reactors (MABR), and closed-circuit reverse osmosis (CCRO) systems).
