L&T Energy GreenTech (LTEG), a wholly-owned subsidiary of Larsen & Toubro (L&T), will build India’s largest green hydrogen plant at Indian Oil Corporation’s (IOCL) Panipat Refinery in Haryana.

The plant will be developed on a build-own-operate (BOO) basis and will supply 10,000 tonne of green hydrogen annually to IOCL for 25 years, supporting the National Green Hydrogen Mission. The plant will operate round the clock using renewable energy, aligning with IOCL’s strategy to decarbonise its refining operations and contribute to India’s net-zero targets. The green hydrogen will be produced using high-pressure alkaline electrolysers manufactured at L&T Electrolysers’s facility in Hazira, Gujarat.

This initiative marks a significant step in India’s energy transition and reinforces L&T’s leadership in building sustainable and scalable clean energy infrastructure. Mr 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. We are proud to lay the foundation for cleaner industrial processes at scale.”
