The plant, to be developed on a build-own-operate (BOO) basis, will supply 10,000 tonnes of green hydrogen annually to IOCL for 25 years, supporting Government of India’s National Green Hydrogen Mission, the company said in a statement.
The plant will operate round the clock using renewable energy, aligning with IOCL’s broader strategy to decarbonise its refining operations and contribute to India’s net-zero ambitions. It will produce the green hydrogen using high-pressure alkaline electrolysers manufactured at L&T Electrolysers’ state-of-the-art facility in Hazira, Gujarat.
Commenting on the development, Subramaniam Sarma, Deputy Managing Director and President, L&T, said, “The decision to set up India’s maiden green hydrogen plant validates our strategy to lead the nation’s energy transition. This long-term project not only deepens our partnership with IOCL but also reinforces our capability to deliver large-scale clean energy solutions. As a first mover in India’s green hydrogen space, we are proud to lay the foundation for cleaner industrial processes at scale.”
Derek Shah, Head – Green Manufacturing and Development, L&T, added, “This project reflects our end-to-end green energy capabilities — from electrolyser manufacturing to execution and operation. With cutting-edge technology and a skilled team, we are confident of delivering a high-performance, zero-emission plant that sets new industry benchmarks. The initiative also supports India’s Aatmanirbhar Bharat mission by deploying indigenously manufactured electrolysers — central to self-reliant clean-tech solutions and long-term decarbonisation goals.”
