Mattiq and Heraeus Precious Metals have entered into a partnership to jointly develop and commercialise low-iridium catalysts for Proton Exchange Membrane (PEM) electrolysers in a bid to lessen dependence on the rare metal. The collaboration aims to expedite the transition from prototype to industrial-scale solutions, addressing the limitations posed by current iridium loading requirements in PEM electrolysers. With iridium being a scarce natural resource, the partnership seeks to optimize its usage to keep pace with the rising need for hydrogen production. Mattiq's proficiency in electrochemical systems design will complement Heraeus' expertise in precious metals reclamation and catalyst manufacturing. Philipp Walter, from Heraeus Precious Metals, highlighted the significance of the partnership in reinforcing their position in electrocatalysis innovation and supporting the energy transition. Jeff Erhardt, CEO of Mattiq, emphasized the collaborative effort to develop high-performance, low-iridium catalysts that can drive down electrolyser manufacturing costs. Moreover, Mattiq recently unveiled a new range of durable iridium alternatives that promise enhanced performance at a reduced cost. The scarcity of iridium, crucial for PEM electrolysis that produces green hydrogen, poses a challenge for achieving the projected electrolyser capacities for the hydrogen economy. Efforts to thrift iridium and recycle untapped sources are essential to sustain the growth of PEM electrolysis. The article underscores the critical role of innovative catalyst development in ensuring the scalability and cost-effectiveness of hydrogen production, crucial for decarbonizing heavy industries in the future.
