Defence Research and Development Organisation (DRDO) has developed an Air Independent Propulsion (AIP) System by proving the land-based prototype on 8 March 2021.
- The plant was operated in endurance mode and max power mode as per the user requirements.
- The system is being developed by Naval Materials Research Laboratory (NMRL) of DRDO.
- AIP has a force multiplier effect on lethality of a diesel electric submarine as it enhances the submerged endurance of the boat, several folds. Fuel cell-based AIP has merits in performance compared to other technologies.
- While there are different types of AIP systems being pursued internationally, fuel cell-based AIP of NMRL is unique as the hydrogen is generated onboard.
