Larsen & Toubro (L&T) India has commissioned its first green hydrogen plant at its AM Naik Heavy Engineering Complex in Hazira, Gujarat. The plant will produce 45 kilogram/day of green hydrogen, and it will be used for captive consumption in the company’s Hazira manufacturing complex. The production of green hydrogen is based on an alkaline electrolysis process, Kallanish notes.
“L&T is at the forefront of providing innovative and sustainable solutions that will help meet the energy needs of the future,” says L&T whole-time director and senior executive vice president Subramanian Sarma. “We are proud that our engineers have set up the green hydrogen generation plant at Hazira complex and integrated it with the existing manufacturing shops for use of the green hydrogen. This initiative is in line with L&T’s climate leadership targets of ‘Lakshya-2026’ that will help reduce greenhouse gases footprint for us as well as our clients by approximately 300 tonnes/year. We believe that green hydrogen is a promising alternative fuel, and this plant is a testimony that we are committed to creating a greener tomorrow."
According to L&T, the green hydrogen plant is designed for an electrolyser capacity of 800 kilowatts, comprising both alkaline (380 kW) and PEM (420 kW) technologies. It will be powered by a rooftop solar plant of 990 kW peak DC capacity and a 500 kWh battery storage system. As part of the first phase of the project, a 380 kW alkaline electrolyser has been installed, while the 420 kW PEM electrolyser along with solar plant capacity augmentation to 1.6 megawatt peak DC will be part of a future expansion, L&T says.
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.
