Smoltek – groundbreaking iridium solution for green hydrogen verified by leading expert
Smoltek Nanotech Holding AB (publ) (“Smoltek” or “the Company”) announces that its subsidiary Smoltek Hydrogen has published a filmed interview with Dr. Felix Büchi, a leading expert in PEM electrolyzers. The interview is about Dr. Büchi’s evaluation of Smoltek Hydrogen’s iridium solution. In the interview, Dr. Büchi confirms that the company’s technology for porous transport electrodes (PTE) in PEM electrolyzers is groundbreaking, as it requires significantly less iridium to achieve the same performance as conventional electrolyzers in hydrogen production.
Dr. Felix Büchi, a leading expert in PEM electrolyzer technology, emphasizes that Smoltek’s porous transport electrode (PTE) solution represents a breakthrough in electrode design for electrolyzers. In an interview with Smoltek Hydrogen’s President, Ellinor Ehrnberg, he shares insights into the technology’s groundbreaking benefits and market potential.
Dr. Felix Büchi, says :
The unique thing about Smoltek’s technology is that it enables the same performance as competing technologies, but with a much smaller amount of iridium on the electrode.
“Smoltek’s PTE uses only 0.1–0.2 mg of iridium per square centimeter without compromising performance,”
For electrolyzer manufacturers, reducing the use of iridium represents a significant opportunity to reduce costs and address supply constraints. Felix Büchi attests that Smoltek Hydrogen’s technology matches industry standards for performance while minimizing the need for precious metals, making it an attractive solution for commercial implementation.
By reducing the amount of iridium by up to 95 percent compared to conventional technology, Smoltek Hydrogen addresses the critical challenge of the severely limited global supply of iridium, which only amounts to about 7 tons per year. A reduced consumption of iridium is a prerequisite for the technology in PEM electrolyzers to be able to be scaled up to the extent required to produce fossil-free (green) hydrogen in the amount required by the carbon-neutral energy transition. In addition, costs are significantly reduced, as the price of iridium already far exceeds the price of gold.
Smoltek’s groundbreaking iridium solution
Smoltek Hydrogen has developed a unique method to grow carbon nanofibers directly onto the porous titanium substrate (PTL), dramatically increasing the catalytic surface area of the electrode. Iridium particles are then deposited in a thin layer onto the corrosion-protected carbon nanofibers. This enables the efficient use of iridium catalysts, even with minimal coating, providing high performance while significantly reducing iridium usage.
Dr. Felix Büchi, says :
What makes Smoltek Hydrogen’s solution unique is that, using their nanostructure, they create a large surface area on the electrically conductive titanium substrate, which ensures that essentially all of the iridium is in electrical contact
Ellinor Ehrnberg, President of Smoltek Hydrogen, says :
By using a technology that so radically reduces the use of iridium, we are addressing the central problem that the entire hydrogen industry is concerned about.
“Dr. Büchi’s evaluation not only confirms that our technology works, but that it is also a key to cost-effective production of green hydrogen that can revolutionize the industry,”
