India’s Green Leap: L&T to Build Nation’s Largest Green Hydrogen Plant at IOCL Panipat Refinery
India is taking a massive stride towards a cleaner, greener future. In a historic development, L&T Energy GreenTech (LTEG), a subsidiary of Larsen & Toubro (L&T), has announced plans to build India’s largest green hydrogen plant at the Indian Oil Corporation’s (IOCL) Panipat refinery in Haryana. This isn't just another infrastructure project; it's a clear reflection of India’s growing commitment to sustainable industrial transformation.What Makes This Project Special?L&T’s new green hydrogen plant at the IOCL Panipat Refinery in Haryana is set to become India’s largest. It will produce 10,000 tonnes of green hydrogen every year for the next 25 years under a Build-Own-Operate (BOO) model. The plant will be powered entirely by renewable energy, making it a clean and sustainable solution for reducing emissions. It will use high-pressure alkaline electrolyzers, which are being manufactured locally at L&T Electrolysers Ltd. in Hazira, Gujarat. This project is a major step toward cutting carbon emissions from one of India’s biggest refineries and supports the country’s goal of becoming a global leader in green hydrogen production.Green Hydrogen: Fuel of the FutureUnlike traditional hydrogen, which is produced using fossil fuels, green hydrogen is made using renewable energy sources like solar or wind power through a process called electrolysis. It emits zero carbon during production, making it one of the cleanest fuels on Earth. By integrating green hydrogen into its operations, IOCL will reduce its reliance on conventional fuels and significantly cut down its carbon footprint, especially in hard-to-abate sectors like refining.This initiative is aligned with the Government of India’s National Green Hydrogen Mission, which aims to make India a global hub for green hydrogen production, usage, and export. It’s part of a larger national goal to achieve net-zero carbon emissions by 2070, and projects like this are vital stepping stones. By deploying indigenously manufactured electrolyzers and leveraging domestic engineering capabilities, this project also supports the Aatmanirbhar Bharat (Self-Reliant India) initiative.Made in India, for the WorldA major highlight of this project is the use of locally manufactured high-pressure alkaline electrolyzers from L&T’s Hazira facility in Gujarat. These electrolyzers are key to splitting water into hydrogen and oxygen using electricity. While much of the conversation around energy is filled with technical aspects, the human angle of this project cannot be ignored. Every tonne of green hydrogen produced will help reduce air pollution, lower carbon emissions, and preserve the environment for future generations. It could also open up new job opportunities, foster innovation, and create a cleaner industrial ecosystem that benefits both local communities and the broader nation. L&T Energy GreenTech: Leading from the FrontL&T Energy GreenTech is rapidly emerging as a central player in India's green energy transition. Operating under three pillars Development, Manufacturing, and EPC (Engineering, Procurement, and construction)—LTEG is uniquely positioned to deliver integrated solutions. With its strong in-house R&D capabilities, strategic global partnerships, and focus on high-quality manufacturing, LTEG is not just keeping up with the world; it's setting new benchmarks. India is currently one of the world's largest energy consumers, and transitioning to clean fuel alternatives is not a choice—it’s a necessity. This Panipat green hydrogen plant is an example for future refineries, a blueprint for the kind of innovation and investment needed to meet global climate goals. It also sends a strong signal to the international community: India is serious about leading the clean energy race, not just following it. As climate challenges grow and the demand for clean energy intensifies, projects like the L&T IOCL green hydrogen plant offer not just solutions but hope. Hope for a more sustainable planet, for a resilient economy, and for cleaner skies.
