Smoltek Nanotech Holding AB's subsidiary, Smoltek Hydrogen, based in Göteborg, Sweden, has initiated a strategic collaboration with Heraeus Precious Metals to enhance the functional efficiency of porous transport electrodes in proton exchange membrane (PEM) electrolyzers. The focus of the partnership is on developing advanced iridium-based catalyst solutions for PEM electrolyzers to drive the next generation of green hydrogen production. By leveraging Smoltek's nanostructure technology and Heraeus' expertise in catalyst formulations, the aim is to significantly reduce the iridium content in PEM electrolyzers, thereby lowering production costs and resource usage. The innovative approach involves combining a porous transport layer that acts as both an electrode and a catalytic carrier, coated with ultra-thin iridium and platinum layers. This unique concept aims to decrease the reliance on platinum group metals, particularly iridium, to accelerate green hydrogen production while ensuring cost-effectiveness. Smoltek has already achieved a low iridium loading of 0.1 mg/cm² in PEM electrolyzers, with expectations to further reduce iridium usage through the partnership with Heraeus. The collaboration highlights the synergy between Smoltek's carbon nanotechnology solutions and Heraeus' industrial expertise, emphasizing the importance of reducing iridium dependency in the hydrogen industry. While the agreement is non-binding and does not immediately generate revenue, it is viewed as a strategic opportunity for Smoltek Hydrogen to expand its market access and customer base through its partners. The partnership signifies a commitment to sustainability and the global energy transition, demonstrating the potential for significant advancements in catalyst efficiency in the growing hydrogen market.
