Promising electrolyser development: 200 times less iridium needed

Produced via electrolysis using electricity from the sun and wind, green hydrogen has a crucial role to play in the energy transition. Iridium is a scarce material that is presently essential to electrolysers working with the commonly used Proton Exchange Membrane (PEM) technology. Researchers at TNO have been the first to develop a method that will require 200 times less iridium where a performance of 25% - 46% of the current generation of electrolysers can already be achieved. A patent application has been made for this method.
