L&T to build India’s largest green hydrogen plant for IOCL
L&T Energy GreenTech Ltd (LTEG), a wholly-owned subsidiary of Larsen & Toubro (L&T), will set up India’s largest green hydrogen plant at Indian Oil Corporation Ltd’s (IOCL) Panipat Refinery in Haryana.
L&T Energy GreenTech will set up India’s largest green hydrogen plant at IOCL’s Panipat Refinery, supplying 10,000 tonnes annually for 25 years.
Powered by renewable energy and using L&T-made electrolysers, the BOO-based project supports India’s Green Hydrogen Mission and net-zero goals, marking a major step in clean industrial energy transition.
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 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 Ltd’s state-of-the-art facility in Hazira, Gujarat.
The initiative marks a significant milestone in India’s energy transition and reinforces L&T’s leadership in delivering sustainable, scalable clean energy infrastructure. With this development, LTEG becomes a pioneer in India’s green hydrogen ecosystem, setting a precedent for industrial-scale adoption across refineries, fertiliser plants, and other hard-to-abate sectors.
Commenting on this, Mr Subramanian 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.”
Complementing him, Mr Derek Shah, Head – Green Manufacturing & 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.”
