DRDO’s Fuel Cell-based Air Independent Propulsion system

In News
  • In a major boost to ‘Aatmanirbhar Bharat’, Fuel Cell-based Air Independent Propulsion (AIP) system of DRDO’s Naval Materials Research Laboratory (NMRL) will soon be fitted onboard INS Kalvari.
About AIP
  • The AIP has a force multiplier effect on lethality of a diesel electric submarine as it enhances the submerged endurance by several folds.
  • It has merits in performance compared to other technologies and is unique as the hydrogen is generated onboard.
  • AIP can augment or replace the diesel-electric propulsion system of non-nuclear vessels.
  • This technology has been successfully developed by NMRL with the support of Indian industry partners.
  • The land-based prototype of the NMRL’s AIP has been tested successfully.
Significance
  • This new endeavour will be a significant step towards the detailed design certification of the energy module, which will be performed by NMRL along with Indian industry and design of the platforms impacted by the integration of the indigenous AIP inside the Indian submarine by Naval Group.
  • These actions will seamlessly lead the way to start of localisation and industrialization of AIP including the hull fabrication by the Indian industry for future fitment on-board the submarines.
  • Only a few countries in the world have access to this unique technology.
