Ohmium designs, manufactures and deploys modular, scalable proton exchange membrane (PEM) electrolyzers aimed at cost-competitive green hydrogen production. The company emphasizes proprietary power electronics, a hyper-modular design and standardized manufacturing to optimize pairing with renewables and drive efficiency and high output. Ohmium reports a global green hydrogen project pipeline of more than 2 GW across three continents and operates worldwide, with manufacturing facilities in India and headquarters in the United States. In April 2023 Ohmium raised $250 million in a Series C led by TPG Rise Climate, strengthening its capital base for scale-up. In July 2024 3M completed a strategic investment and the companies intend to collaborate on advanced materials and catalysts to further enhance electrolyzer performance. Ohmium targets decarbonization of hard-to-abate industrial sectors such as steel manufacturing and fertilizer production through its PEM electrolyzer products. Ohmium develops modular PEM electrolyzers that produce pressurized, high‑purity hydrogen and can be stacked to scale from megawatts to gigawatts. The company emphasizes dynamic ramping, high current density, scalability, and safety to pair with renewable electricity and serve hard‑to‑abate industries. Ohmium is headquartered in the United States, with manufacturing in India and operations worldwide. The company reports a growing global customer pipeline and says it is on track to deliver systems to customers across multiple sectors in 2023. Ohmium is investing in R&D to reduce the cost of green hydrogen production and to accelerate its technology development. The firm highlights a standardized, modular design intended to reduce installation and maintenance costs and enable rapid scaling. Ohmium International designs, manufactures, and deploys Proton Exchange Membrane (PEM) electrolyzers that produce pressurized high‑purity hydrogen. The company manufactures standardized interlocking modular electrolyzers that can be stacked to reduce installation and maintenance costs while enabling flexible deployment sizes. Ohmium's proprietary electrolyzer stack technology can sustain a differential pressure across the membrane without compromise, supporting more cost‑effective operations. Its suite of electrochemical products targets industrial, transportation, and energy projects. Ohmium operates R&D facilities in the United States and India and has manufacturing operations in India. The company closed a $45M Series B and plans to use the funds to increase manufacturing capacity from 500 MW annually to approximately 2 GW by the end of 2022.
