Nornickel introduces new tech for carbon-free energy industry at Chinese conference

27 march 2024

Norilsk Nickel has showcased its cutting-edge developments in utilizing palladium for carbon-free energy generation, including hydrogen, at a major energy conference in China.

Following the conference, the company was accepted into the China Hydrogen Alliance.

Nornickel noted that its scientists are focusing on the research and development of new palladium-based solutions capable of significantly enhancing the efficiency of fossil-free technologies in areas such as hydrogen and solar energy, chemical synthesis, and microelectronics.

The company expects the electrolyzer market to grow rapidly over the next 10 years. Hence, Nornickel is engaged in research and development in this area, offering innovative palladium-based solutions that could reduce costs and improve hydrogen production efficiency.

Additionally, the company is developing new palladium materials for solar power, which could increase generation efficiency and support a technological breakthrough in the solar sector.

Anna Karzhavina, head of new product commercialization at Nornickel, commented: “Nornickel reaffirms its commitment to innovation and sustainable development by investing significant resources into the research and development of new palladium-based products. These efforts are aimed not only at enhancing current technologies in hydrogen and solar energy but also at discovering new applications for palladium in the future.”

The company’s scientific developments have shown promising results. Specifically, replacing iridium with palladium in proton exchange membrane (PEM) electrolyzers promises a significant reduction in cost while simultaneously increasing catalyst activity. This breakthrough could radically transform the hydrogen industry, making it more accessible and efficient.

The results of palladium-based catalyst tests conducted in Russia showed a threefold increase in activity while maintaining high stability and degradation rates comparable to iridium oxide. In 2024, Nornickel anticipates a report from an independent laboratory, which will allow presenting innovative solutions for hydrogen generation on the global market.

Metals Focus, an independent precious metals research consultancy, forecasts a rise in palladium consumption in hydrogen energy to 1.25 million troy ounces in the near future. Nornickel is confident that the company’s developments can capture 25-40% of this market by offering efficient solutions across the entire hydrogen production chain.
