UK’s ITM Power has concluded a technical milestone in electrolyzer technology development, having validated an additional 40% iridium loading reduction whilst maintaining stack performance and longevity.
The manufacturer shared that the development of its next-generation stack platform, CHRONOS, is proceeding to plan, adding that the platform will be a vehicle for adopting several technology improvements from the company’s development roadmap.
“As testing progresses, the validation of several features will be completed, many of which will also be implemented into the current TRIDENT stack platform. The step change reduction in iridium loading will be the first to be triggered for adoption for both platforms,” ITM Power revealed.
Dennis Schulz, CEO of ITM Power, commented: “As part of a structured validation process, we have successfully reduced iridium loading by a further 40% without detriment to performance or degradation. As a costly raw material, reducing iridium benefits stack costs significantly. This loading reduction and our catalyst recovery and reuse processes will substantially reduce our consumption of critical raw materials and further lower our cost.”
To note, the company already lowered loading by over 80% in the past years and met the EU’s 2030 precious metal loading target for PEM electrolyzers in 2019.
In 2024, ITM Power signed a 500 MW capacity reservation with an undisclosed global industrial customer and was appointed by UK’s Hygen Energy as a preferred supplier of PEM electrolyzers for hydrogen projects within the UK and across wider Europe.
Furthermore, in collaboration with Japan’s Sumitomo Corporation, the company completed the delivery and installation of a NEPTUNE electrolyzer at Tokyo Gas’ Yokohama Techno Station.
