Ohmium opens a new gigafactory in Doddaballapura, near Bengaluru, India.
This 14,000-square-meter facility will produce up to 2 gigawatts (GW) of PEM electrolyzers to meet the growing need for green hydrogen.
Since 2022, Ohmium has placed considerable emphasis on the development of hydrogen energy.
The company is also stepping up its projects abroad, such as the collaboration with Green Mining in Chile.

Strategic Expansion

Ohmium inaugurates its new gigafactory, capable of producing 2GW of PEM electrolyzers.
Arne Ballantine, Ohmium’s CEO, points out that this capacity will reduce 4 million tonnes of CO2 per year, the equivalent of 180 million trees capturing CO2.
This expansion marks a crucial step in the company’s global strategy.
The plant integrates manufacturing, assembly, quality control, testing, storage and shipping processes all under one roof.
Ashwin Varma, COO, explains that Ohmium’s hyper-modular electrolyzers are designed for mass production and easy assembly, ensuring superior performance at a competitive cost.
Production can be rapidly scaled up to meet growing demand, generating economies of scale.

Investments and Partnerships

The Gigafactory represents a significant investment in real estate, equipment and local talent.
This project is part of a series of successes for Ohmium in India, including a 400 MW agreement with NTPC in 2023 and a strategic partnership with Tata Projects in 2024.
Ohmium has also been selected for incentives from the Ministry of Renewable Energy as part of strategic interventions for the transition to green hydrogen.
Collaborations with CSIR-Central Electrochemical Research Institute and IIT Madras Research Park facilitate the rapid transfer of innovations to production, meeting the growing demand for green hydrogen projects.
