What We Do
Ohmium's mission is to accelerate the adoption of green hydrogen to decarbonize hard-to-abate sectors and enable a low-carbon future. Ohmium designs, manufactures and deploys modular, scalable proton exchange membrane (PEM) electrolyzer systems that enable cost-competitive green hydrogen production. Ohmium’s systems are vertically-stackable and integrate advanced power electronics, delivering superior value for a wide range of commercial and industrial applications in terms of safety, energy density, scalability and ramp rate. The human-scale electrolyzers are efficient to manufacture, quick to transport and easy to maintain. This versatility enables cost-effective plug-and-play operations that can scale rapidly. Ohmium has a global green hydrogen project pipeline across the U.S., Mexico, Europe and Asia.
