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.
Project Details and Impact
This pioneering plant will operate on a build-own-operate (BOO) basis, supplying 10,000 tonnes of green hydrogen annually to IOCL for a period of 25 years. This significant initiative directly supports the Government of India’s National Green Hydrogen Mission.
The facility will run using renewable energy, aligning with IOCL’s broader strategy to decarbonize its refining operations and contribute to India’s ambitious net-zero emissions targets. The green hydrogen will be produced using high-pressure alkaline electrolysers manufactured at L&T Electrolysers Ltd’s advanced facility in Hazira, Gujarat.
A Milestone for India’s Energy Transition
This project marks a crucial milestone in India’s energy transition, solidifying L&T’s leadership in delivering sustainable and scalable clean energy infrastructure. With this development, LTEG emerges as a trailblazer in India’s green hydrogen ecosystem, establishing a precedent for widespread industrial-scale adoption across various sectors, including refineries, fertilizer plants, and other hard-to-abate industries.
Leadership Comments
Subramanian Sarma, Deputy Managing Director & President, L&T, emphasized the strategic importance of the project: “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.”
Adding to this, Derek Shah, Head – Green Manufacturing & Development, L&T, highlighted the comprehensive capabilities involved: “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.”
