Ohmium International, a US-based developer of electrolyser systems for green hydrogen production, announced plans to double its manufacturing capacity in Karnataka, India, from 2 GW to 4 GW by 2026. The company recently opened a new giga factory in Dodaballapura, near Bengaluru.
Ohmium specializes in Proton Exchange Membrane (PEM) electrolysers, which are essential for producing green hydrogen. This process involves splitting water into oxygen and hydrogen using electricity from renewable sources, helping to reduce carbon emissions in various industries.
The company has two R&D centers in India, located in Chennai and Bengaluru, along with its manufacturing facility in Karnataka. CEO and Co-founder Arne Ballantine stated that as orders increase, the new factory will initially be about 10% full, with expectations to grow as project sizes increase to 100-200 MW.
Ohmium plans to use India as a hub for operations and engineering, with strong connections to IIT Madras and its tech park. The current manufacturing facility has a capacity of 500 MW. The new gigafactory is Ohmium’s second in India and the first to integrate key manufacturing, assembly, quality assurance, testing, warehouse, and shipping operations under one roof.
COO Ashwin Varma highlighted that Ohmium’s PEM electrolysers are designed for mass production and easy assembly. According to Ballantine, 2 GW of electrolyzers can reduce CO2 emissions by four million tons annually, equivalent to the CO2 captured by 180 million trees. The new gigafactory represents a significant investment in local real estate, equipment, and talent.
Ohmium has a strong track record in India, including a 400 MW deal with NTPC in 2023, a strategic partnership with Tata Projects in 2024, and selection for the Ministry of Renewable Energy’s SIGHT Incentives program. The company collaborates with CSIR-Central Electrochemical Research Institute and IIT Madras Research Park to rapidly transfer innovations into production to meet the growing demand for green hydrogen.
