Larsen & Toubro's subsidiary, L&T Energy GreenTech Ltd (LTEG), is set to build India's largest green hydrogen plant at the Indian Oil Corporation's Panipat refinery in Haryana. The project, developed on a Build-Own-Operate (BOO) model, will have a production capacity of 10,000 tons of green hydrogen annually using high-pressure alkaline electrolysers. With a 25-year contract, the plant aims to support the Government of India's National Green Hydrogen Mission and reinforces the country's decarbonization efforts. The bidding process saw L&T winning the contract at a competitive rate of ₹397 per kg, signaling cost-effectiveness and investor appeal. Additionally, the project showcases L&T's full-stack integration, from manufacturing to operation, boosting its profile in the low-carbon infrastructure sector. This initiative not only marks a significant step towards green energy transition but also enhances India's position in the global hydrogen economy, fostering sustainable industrial practices and green technology adoption.
