What They Do

Ohmium specializes in the production of green hydrogen through advanced Proton Exchange Membrane (PEM) electrolyzers. These electrolyzers utilize water and renewable energy sources to generate high-purity hydrogen without relying on fossil fuels (source: ohmium.com). Their flagship product, the Lotus Mark 2 electrolyzer, features a hyper-modular design that includes a centralized water purification unit, glycol-based cooling, and proprietary power electronics, all integrated into a compact footprint that allows for vertical stacking and deployment in various climates (source: ohmium.com). The company offers services such as global remote monitoring and maintenance, ensuring scalability from megawatt to gigawatt levels through standardized designs manufactured in India (source: ohmium.com). Target markets include industrial applications, power generation, and transportation fuels, focusing on sectors that are challenging to decarbonize across the U.S., Europe, India, and the Middle East (source: ohmium.com). Ohmium's competitive edge lies in its high current density, dynamic ramping capabilities, and superior iridium utilization, positioning it favorably against industry competitors like ITM Power and Siemens Energy (source: ohmium.com).

In Spain, Ohmium has committed to supplying up to 52 tons of green hydrogen annually for the EFFI SOLAR GREENH2 PORTUARIO project, which will replace methane in gas flares, significantly reducing CO2 emissions (source: ohmium.com). Additionally, the company signed a term sheet for 300 MW PEM electrolyzers for the OFFSET offshore floating green hydrogen and ammonia project in Southern Europe, with production expected by 2029 (source: canvasbusinessmodel.com).
