H2U Technologies, a next-generation electrolyzer developer, has performed durability tests on new, lower-cost, iridium-free catalyst materials that demonstrate a projected lifetime of 25,000 hours. This groundbreaking durability milestone represents a significant breakthrough and addresses supply chain bottlenecks for sustainable hydrogen production with Proton Exchange Membrane (PEM) electrolyzers, the H2U Technologies said.
For perspective, the best iridium-free catalysts known to date offer lifetimes of approximately 1,000 to 1,400 hours. With a baseline of over 4,000 hours of continuous operation thus far, H2U’s iridium-free catalysts, tested at 10x higher current density, are demonstrating projected lifetimes of over 25,000 hours. H2U catalysts are projected to last at least six years for targeted applications, such as in PEM electrolyzers paired with curtailed renewables.
