New Catalyst Cuts The Cost Of Green Hydrogen

The article highlights a significant advancement in reducing the cost of green hydrogen production through a new catalyst developed by a collaboration between US startup Plug Power, Dutch firm VSParticle, and the University of Delaware. Green hydrogen, produced by splitting water using renewable electricity, typically relies on iridium-based catalysts, which are highly efficient but expensive and scarce. VSParticle’s innovation uses 90% less iridium than conventional catalysts by employing a novel dry deposition manufacturing process instead of traditional spray coating. This method not only optimizes iridium usage but also eliminates the need for harmful PFAS-based polymers and solvents, resulting in a more sustainable and cost-effective catalyst. The new catalyst features a uniform, nanoporous structure that significantly increases the active surface area of iridium, enhancing efficiency while reducing material costs. VSParticle reports achieving high efficiency with just 0.4 milligrams of iridium per square centimeter, compared to the usual 1-2 milligrams, and aims to bring the cost of green hydrogen down to $
