L&T Energy GreenTech Ltd will set up India’s largest green hydrogen plant at IOCL’s Panipat Refinery, Haryana. With an annual supply of 10,000 tonnes of green hydrogen for the next 25 years, this project is a major step forward in realizing the National Green Hydrogen Mission.

L&T Energy GreenTech Ltd (LTEG), a wholly owned subsidiary of Larsen & Toubro (L&T), is set to establish India's largest green hydrogen plant at Indian Oil Corporation Ltd's (IOCL) Panipat Refinery in Haryana.

The facility, developed on a build-own-operate (BOO) basis, will supply 10,000 tonnes of green hydrogen annually to IOCL for 25 years, aligning with the Government of India's National Green Hydrogen Mission. Operating round the clock using renewable energy, the plant aims to decarbonise IOCL's refining operations and contribute to India's net-zero goals.

Green hydrogen production will utilise high-pressure alkaline electrolysers manufactured at L&T Electrolysers Ltd's state-of-the-art facility in Hazira, Gujarat. This initiative underscores L&T's leadership in delivering sustainable, scalable clean energy infrastructure.

LTEG's involvement marks a significant milestone in India's energy transition, setting a precedent for industrial-scale adoption across refineries and other hard-to-abate sectors.

The project reflects L&T's end-to-end green energy capabilities, from electrolyser manufacturing to execution and operation. With cutting-edge technology and a skilled team, LTEG aims to deliver a high-performance, zero-emission plant that sets new industry benchmarks.

This development also supports India's Aatmanirbhar Bharat mission by deploying indigenous technology and resources.
