Larsen & Toubro (L&T) has signed a contract with DRDO for realisation of two Air Independent Propulsion (AIP) System Modules for Kalvari Class of Submarines of the Indian Navy. These Modules constitute the core of the fuel cell based AIP System, indigenously developed by Naval Materials Research Laboratory (NMRL) of DRDO with L&T as prime industry partner, an association spanning more than a decade. The Energy Modules (EMs) comprising Fuel Cells produce the required power, along with on-board Hydrogen generation. The technology of this indigenous AIP system is a unique one that generates hydrogen on demand thereby obviating the need for carrying hydrogen onboard which is a major safety concern for a submarine.
On realisation and integration of these modules in the submarines, India will join an elite club of a handful of nations who have indigenously developed fuel cell based submarine AIP technology which is critical for increasing the endurance of conventional submarines. It is pertinent to mention here that principally this technology is a green one since the by-product of the reaction is non-polluted water which can be released into the oceans.
L&T is an Indian multinational engaged in technology, engineering, construction, manufacturing and financial services.
