Indian multinational engineering group, Larsen & Toubro, has commissioned a green hydrogen plant in Gujarat as part of its efforts to play a major role in accelerating an ecosystem around green hydrogen.

The 380 kW of an 800 kW green hydrogen plant at its AM Naik Heavy Engineering Complex in Hazira, Gujarat, is spread across 3,000 square metres and will produce 45 kg of green hydrogen per day for self-consumption. 

It said the operational 380 kW capacity uses an alkaline electrolysis process. The remaining 420 kW capacity will be based on PEM electrolysis technology. 

“The green hydrogen plant is designed for an electrolyser capacity of 800 kW comprising both alkaline (380 kW) and PEM (420 kW) technologies,” said Larsen & Toubro. “It will be powered by a rooftop solar plant of 990 kW peak DC capacity and a 500kWh battery energy storage system. The 420 kW PEM electrolyser, along with solar plant capacity augmentation to 1.6 MW peak DC, will be part of future expansion.” 

Larsen & Toubro set up the green hydrogen generation plant and integrated it with the existing manufacturing facilities to use the high-purity green hydrogen (99.99 per cent) and oxygen that is produced. The manufacturing facility will use a blend of 15 per cent hydrogen with natural gas as a fuel. Oxygen will supplement the existing usage in cutting and welding applications. 

The plant design incorporates both active and passive safety systems to ensure safe operation and production. It will be operated through control systems with remote monitoring functionality, the company said. 

In addition, an integrated data analytics platform designed by Larsen & Toubro will provide insight into the performance of the electrolyzers and the overall plant.
