Ohmium halves iridium use in its PEM electrolyzer

Ohmium has reached an 18 GW per ton iridium utilization rate in its proton exchange membrane (PEM) electrolyzer, surpassing the industry’s 2030 target of 10 GW per ton.

 

The company said it has made significant technological advancements that have resulted in reducing iridium usage by 50% in its Lotus electrolyzer, Mark 2. This supports the cost-competitiveness of green hydrogen production by lowering the overall cost of PEM electrolyzers.

 

Dr Chock Karuppiah, Chief Science and Technology Officer, said: “We’ve made significant strides in reducing iridium usage in our PEM electrolyzers, exceeding the 2030 industry target of 10 GW per ton. We’ve achieved a utilization rate of 18 GW per ton. This innovation is crucial, as iridium is one of the most expensive materials in electrolyzer manufacturing.”

 

Chief Executive Officer Dr Markus Tacke added: “We’re 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.”

 

The company aims to double utilization efficiency to 36 GW per ton or less within another year, a step it said will move it closer to its goal of near-zero iridium usage within a decade.
