Heraeus Precious Metals and Sibanye-Stillwater are partnering to explore new applications for platinum-group metals (PGM) in the hydrogen economy, specifically how existing or new applications could profit from the unique traits of palladium. The joint aim is to develop alternative markets for palladium and support the emerging hydrogen sector with technical innovations. The project will be equally funded by both parties.
Palladium has a very high selectivity for hydrogen and thus can be used in a broad range of applications. The increasing demand for the purification of hydrogen during blue hydrogen production is one possible example of a palladium-based application. Further examples include the cracking of hydrogen carriers and the semiconductor industry, where high-purity hydrogen is needed as a process gas.
As a market-leading player in technology development for PGMs and their recycling, Heraeus Precious Metals is contributing its technical expertise and experience in scaling up and optimizing catalytic processes. Sibanye-Stillwater, one of the world’s largest producers of PGMs continues to seek innovative applications and develop new markets for PGMs. Previous joint projects have already shown impressive results, such as the recent development of a stable ruthenium-based catalyst for PEM (Proton Exchange Membrane) Water Electrolysis.
