Ohmium International Inc., a provider of high-efficiency and modular proton exchange membrane (PEM) electrolysers, has surpassed the electrolyser industry's 2030 target of 10 GW/t to attain an 18 GW/t iridium utilisation rate. Ohmium has made significant technological advancements which have resulted in reducing its iridium usage by 50% in its Lotus electrolyser, Mark 2.
This enhances the cost-competitiveness of green hydrogen production by reducing the overall cost of its PEM electrolysers, which have been impacted by the cost of the precious metal, iridium.
Dr Chock Karuppiah, Chief Science and Technology Officer at Ohmium, said: "We have made significant strides in reducing iridium usage in our PEM electrolysers, exceeding the 2030 industry target of 10 GW/t. We have achieved a utilisation rate of 18 GW/t. This innovation is crucial, as iridium is one of the most expensive materials in electrolyser manufacturing.”
Dr Markus Tacke, Chief Executive Officer at Ohmium, added: "We are proud of the team's hard work and achievements. By reducing iridium usage and leveraging our high system efficiency (48 kWh/kg), Ohmium is lowering the cost of green hydrogen production and enhancing the overall cost-efficiency of our green hydrogen solutions.”
Ohmium endeavours to further optimise its technology, with goals to double the utilisation efficiency to 36 GW/t or less within another year. This progress is expected to move Ohmium closer to its target of near zero iridium usage within a decade. The company's achievement represents a significant milestone in the development of PEM electrolyser technology, paving the way for more widespread adoption of green hydrogen solutions and supporting the global transition to a low-carbon economy.
