Ohmium International, a leader in high-efficiency, modular Proton Exchange Membrane (PEM) electrolyzers, has shattered industry expectations by achieving an 18 GW-per-ton iridium utilization rate—far surpassing the 2030 target of 10 GW per tonne.

The breakthrough comes with the launch of the Lotus Electrolyzer Mark 2, which cuts iridium usage by 50%, dramatically lowering the cost of green hydrogen production. Iridium, one of the rarest and most expensive metals in electrolyzer manufacturing, has long been a barrier to cost-effective hydrogen solutions.

Dr. Chock Karuppaiah, Ohmium Chief Science and Technology Officer, emphasized the significance of the milestone: “We've exceeded the 2030 industry target of 10 GW per tonne, achieving 18 GW per tonne. This innovation is critical, given the high cost of iridium, and it positions green hydrogen as a more affordable energy solution.”

Ohmium CEO Dr Markus Tacke praised the team’s efforts, noting that the company’s high system efficiency—48 kWh per kilogram of hydrogen—combined with reduced iridium usage, is making green hydrogen more cost-competitive than ever. “This is a major step forward in lowering the cost of green hydrogen and advancing our mission for sustainable energy,” he said.

The company isn’t stopping there. Ohmium plans to double its iridium utilization efficiency to 36 GW per tonne within a year and aims for near-zero iridium usage within a decade. These ambitious goals are expected to accelerate the adoption of PEM electrolyzers and help drive the global transition to a low-carbon economy.

Ohmium’s breakthrough represents a critical milestone for the green hydrogen industry, addressing both economic and resource constraints. By improving the efficiency and affordability of PEM electrolyzers, the company is paving the way for wider adoption of green hydrogen, a key component in achieving global climate targets.
