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).
Projects & Track Record
Ohmium has established a robust global project pipeline exceeding 2 GW, demonstrating its reliability in extreme conditions (source: ohmium.com). Among its notable projects is the supply of a 10 MW PEM electrolyzer for Croatia's INA Rijeka Refinery, which aims to decarbonize operations and fuel transport, supported by the EU Recovery and Resilience Facility (source: advancedbiofuelsusa.info). 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). Ohmium's partnerships include collaborations with Invenergy for turbine cooling at the Nelson Energy Center and involvement in India's first green methanol plant (source: cbinsights.com).
Recent Developments
In 2023, Ohmium successfully raised $250 million in Series C financing led by TPG Rise Climate, aimed at scaling manufacturing to 2 GW annual capacity and expanding R&D efforts (source: esgtoday.com). This followed a $45 million Series B round in April 2022, bringing total funding to $311.2 million by late 2025 (source: cbinsights.com). The company also inaugurated a PEM electrolyzer gigafactory in India, which is expected to abate 4 million tons of CO2 annually (source: ohmium.com). In 2024, Ohmium secured a term sheet for a 300 MW project in Southern Europe and partnered for India's first green methanol plant, showcasing its commitment to expanding its footprint in the green hydrogen sector (source: canvasbusinessmodel.com). By 2025, Ohmium achieved UL Solutions' first industrial certification for hydrogen generators using water electrolysis, further solidifying its position in the market (source: ohmium.com).
