Naval Group to Integrate Indian-made Air Independent Propulsion onto P75 Submarines

Our Bureau 553 INS Kalvari, first of India s Scorpene Class Submarine. MoD Image Naval Group will commence detailed studies on the integration of an Indian DRDO - developed Air Independent Propulsion (AIP) system into the P75 Scorpene submarine platform. India’s DRDO proved the land-based prototype of a fuel-cell based AIP system as recently as 8 March 2021. The AIP system is being developed by Naval Materials Research Laboratory (NMRL) of DRDO with the support of industry partners L&T and Thermax. It has now reached the stage of maturity for fitment into target vessels, DRDO had announced last month. The AIP will be integrated into project P75 submarines during retrofitting, Naval Group asserted in a release.

IIT Hyderabad develops dual carbon alternative to lithium-ion batteries

IIT Hyderabad develops dual carbon alternative to lithium-ion batteries The breakthrough model, developed by a team led by Dr Surendra Kumar Martha, eliminates the requirement of toxic, costly, and heavy transitional metals. By IANS|   Posted by Minhaj Adnan  |   Published: 5th April 2021 2:56 pm IST Hyderabad: The Electrochemical Energy Storage Lab at the Indian Institute of Technology Hyderabad (IITH), has developed a 5V Dual Carbon Battery utilising self-standing carbon fibre mats as both electrodes – cathode and anode. The breakthrough model, developed by a team led by Dr Surendra Kumar Martha, eliminates the requirement of toxic, costly, and heavy transitional metals. This more sustainable and low-cost Dual carbon battery may find potential uses in high-voltage applications, sophisticated battery-run medical devices, regenerative braking systems in electric vehicles, and stationary grids.
