L&T Energy GreenTech to Build India's Largest Green Hydrogen Plant

L&T Energy GreenTech Ltd, a wholly-owned subsidiary of Larsen & Toubro, announced plans to establish India's largest green hydrogen plant at Indian Oil Corporation Ltd's Panipat Refinery in Haryana. The facility will produce 10,000 tonnes of green hydrogen annually under a 25-year supply contract with IOCL.

The plant will operate on a build-own-operate basis and will run continuously using renewable energy sources. Production will utilize high-pressure alkaline electrolysers manufactured at L&T Electrolysers Ltd's facility in Hazira, Gujarat. The project aligns with IOCL's strategy to reduce carbon emissions from its refining operations and supports India's net-zero emission goals.

The initiative represents a development in India's green hydrogen sector and supports the Government of India's National Green Hydrogen Mission. Green hydrogen, produced through electrolysis using renewable energy, generates no carbon emissions during production and can replace conventional hydrogen in industrial processes.

Subramaniam Sarma, Deputy Managing Director and President of L&T, stated the project validates the company's approach to leading India's energy transition. He noted the development deepens L&T's partnership with IOCL while demonstrating the company's capacity to deliver large-scale clean energy solutions.

Derek Shah, Head of Green Manufacturing & Development at L&T, emphasized the project showcases the company's integrated green energy capabilities spanning electrolyser manufacturing to plant operation. He highlighted the use of indigenously manufactured electrolysers supports India's Aatmanirbhar Bharat self-reliance initiative.

The project positions L&T Energy GreenTech as a pioneer in India's green hydrogen ecosystem and could establish a model for adoption across refineries, fertiliser plants, and other industrial sectors that are difficult to decarbonise. The development marks L&T's entry into commercial-scale green hydrogen production in India's emerging clean energy market.

L&T Energy GreenTech operates as part of the USD 30 billion Larsen & Toubro conglomerate and focuses on sustainable energy solutions including green hydrogen, derivatives, and electrolyser manufacturing. The subsidiary's business model encompasses development, manufacturing, and engineering procurement construction services across the green energy value chain.
