Larsen & Toubro installs its first electrolyser — made in-house in India using licensed McPhy technology




The EPC firm commissions pressurised alkaline equipment at heavy engineering yard in Gujarat


Indian engineering company Larsen & Toubro (L&T) has announced that it has commissioned its first electrolyser made in India at the A M Naik Heavy Engineering Complex at the port of Hazira in the state of Gujarat.


This 1MW electrolyser was manufactured under L&T’s licensing agreement with French firm McPhy for its pressurised alkaline technology, although the Indian engineering company highlighted that it worked with domestic partners throughout the supply chain.


L&T also confirms that it plans to develop a previously announced electrolyser gigafactory in Hazira.


The engineering firm had in January only been allocated subsidies for 63MW of the 300MW of annual manufacturing capacity it had bid for.


However, a revised list of tender winners published at the end of February now awards L&T up to 4.44 billion rupees ($53.5m) for the full 300MW/year over the next five years.


L&T had previously installed a pilot green hydrogen plant at the A M Naik complex in 2022, pre-dating its agreement with McPhy, with volumes blended into the engineering yard’s existing natural gas consumption.


However, it is unclear which electrolyser supplier was used for the first pilot project — nor even how much production capacity the facility has.


While L&T has described the pilot as designed for 800kW of electrolysers, it only announced 380kW of alkaline electrolysis capacity, with no further update on whether it ever installed the planned 420kW of proton exchange membrane (PEM) technology.
