US-based renewable energy start-up, Ohmium International, has established India’s first green hydrogen electrolyzer gigafactory at Bengaluru through its India subsidiary. The move comes at a time when the industry majors like Reliance Industries, Adani Group, state-run Indian Oil Corporation (IOC), NTPC and Gail India have all shown interest in becoming part of India’s green hydrogen roadmap.
The gigafactory will manufacture India-made Proton Exchange Membrane (PEM) hydrogen electrolyzers with an initial manufacturing capacity of about 500 megawatt (MW) per year and will scale it up to 2 gigawatt (GW) per year.
While blue hydrogen is created from fossil sources, where the carbon emissions are captured and stored, green hydrogen is made from non-fossil sources. To produce green hydrogen through any process, electrolysis is required. Electrolysis is the process used to split water into oxygen and hydrogen. An electrolyser is the system in which electrolysis is done, making it the most vital part in terms of making hydrogen economically viable.
According to the company press release, the PEM hydrogen electrolyzer is the main equipment for the production of green hydrogen as it uses power generated from renewable resources to break water into hydrogen and oxygen.
“Our products are modular, high performance, and high value. This ensures that they can be utilised to achieve levelized costs of hydrogen which support the growth of India’s economy,” said Arne Ballantine, chief executive officer, and co-founder, Ohmium.
The start-up has developed technology that can be both distributed and scaled-up. “We are firmly aligned to India’s vision. By further boosting the production of green hydrogen within India, we aim to make the nation an export hub for green fuel,” said Pashupathy Gopalan, an Ohmium Investor. The company said that it would ensure availability of an end-to-end solution within the country and cut down dependence on imports for this key equipment.
