Larsen & Toubro (L&T) has recently commissioned a new green hydrogen plant at its AM Naik Heavy Engineering Complex in Hazira, Gujarat. Expected to produce 45 kg of green hydrogen daily, the facility’s first phase comprising 380 kW alkaline electrolyzer has been installed, while the PEM electrolyzer along with solar plant capacity augmentation will be installed in the future.

Mumbai/India – Larsen & Toubro (L&T) recently announced the commissioning of a green hydrogen plant at its AM Naik Heavy Engineering Complex in Hazira, Gujarat. The plant was inaugurated by Shrikant Madhav Vaidya, Chairman – Indian Oil Corporation. The production of green hydrogen based on an alkaline electrolysis process has recently begun. The plant will produce 45 kg of green hydrogen daily, which will be used for captive consumption in the company’s Hazira manufacturing complex.

The green hydrogen plant is designed for an electrolyzer capacity of 800 kW comprising both alkaline (380 kW) and PEM (420 kW) technologies and will be powered by a rooftop solar plant of 990kW peak DC capacity and a 500kWh Battery Energy Storage System (BESS). As part of the first phase of the project, 380 kW alkaline electrolyzer has been installed, while the 420 kW PEM electrolyzer along with solar plant capacity augmentation to 1.6 MW peak DC, will be part of future expansion.

The plant is spread across 3000 sq. meters, and the first phase of the project has been installed, tested, and commissioned. The scope involves the generation of high purity green hydrogen (99.99 %) and oxygen, and their captive consumption in the manufacturing shops. A blend of 15 % hydrogen with natural gas will be used as a fuel, and oxygen will supplement the existing usage in cutting and welding applications.

To ensure safe operation and production, the plant design incorporates both active and passive safety systems and will be operated through state-of-the-art control systems with remote monitoring functionality. In addition, an integrated data analytics platform designed by L&T will provide insights into the performance of the electrolyzers and the overall plant.
