Larsen and Toubro has commissioned its first indigenously manufactured hydrogen electrolyser at the green hydrogen plant in Hazira, Gujarat.

The company said this signifies L&T Electrolyser Ltd's foray into the domestic electrolyser manufacturing.

"Featuring a rated power capacity of 1 MW (expandable to 2 MW), this electrolyser can produce 200 Nm3/Hr of hydrogen. It is equipped with two stacks and an electrolyser processing unit ML-400, and offers exceptional flexibility and thermal stability," the company said in a stock exchange filing, adding that in the coming weeks, the electrolyser would be undergoing rigorous testing to optimise its performance.

Hydrogen is made by splitting H2O (water) into two molecules -- hydrogen and oxygen — via electrolysis, which is an electrical process. The method requires electrolysers, and if the same is powered by renewable energy, then the product formed is green hydrogen — a fuel that is free of greenhouse emissions.
