L&T Energy GreenTech to set up India's largest green hydrogen plant for Indian Oil refinery

L&T Energy GreenTech Ltd will set up India's largest green hydrogen plant at Indian Oil Corporation Ltd’s (IOCL) Panipat Refinery in Haryana, the company announced on Monday.

The plant will operate 24/7 using renewable energy, supporting IOCS's strategy to decarbonise its refining operations and contribute to country's net-zero ambitions.




The green hydrogen plant will be developed on a build-own-operate (BOO) basis. It 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 produce green hydrogen using high-pressure alkaline electrolysers manufactured at L&T Electrolysers Ltd’s facility in Hazira, Gujarat, as per company release.

The initiative marks a significant milestone in India’s energy transition and reinforces L&T’s leadership in delivering sustainable, scalable clean energy infrastructure, the company 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," said Subramaniam Sarma, Deputy Managing Director & President, L&T.

"This project reflects our end-to-end green energy capabilities — from electrolyser manufacturing to execution and operation," Derek Shah, Head – Green Manufacturing & Development, L&T added.
