Smoltek Hydrogen's Iridium-Saving Technology Gains Endorsement from Dr. Felix Büchi
Smoltek Nanotech Holding AB (publ) ("Smoltek") announced that its subsidiary, Smoltek Hydrogen, has released a filmed interview featuring Dr. Felix Büchi, a leading expert in PEM electrolyzers. Dr. Büchi evaluated Smoltek's innovative Porous Transport Electrode (PTE) technology, which drastically reduces iridium usage without compromising performance.
Dr. Büchi highlighted the groundbreaking nature of Smoltek Hydrogen's PTE solution, which achieves industry-standard performance with just 0.1–0.2 mg of iridium per square centimeter. This represents up to a 95% reduction in iridium usage compared to conventional PEM electrolyzers, addressing the critical challenge of limited global iridium supplies, estimated at only 7 tons annually.
Smoltek's method grows carbon nanofibers directly on a porous titanium substrate, increasing the catalytic surface area. Iridium particles are applied as a thin layer on these nanofibers, ensuring efficient use and high performance while significantly cutting costs, as iridium prices exceed those of gold.
Dr. Büchi, who has over 20 years of experience in electrolyzer research at the Paul Scherrer Institute and has authored 50 scientific articles on PEM technology, affirmed the market potential of Smoltek’s solution. He stated that this advancement could enable scalable, cost-effective green hydrogen production essential for achieving carbon neutrality.
Ellinor Ehrnberg, CEO of Smoltek Hydrogen, emphasized that the evaluation validates their technology as a revolutionary step for the hydrogen industry.
