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.

The plant will operate round the clock using renewable energy. It will produce the green hydrogen using high-pressure alkaline electrolysers manufactured at L&T Electrolysers’ facility in Hazira, Gujarat.

Subramaniam Sarma, deputy managing director & 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.'
