2. ENERGY: WHY INDIGENOUS TECHNOLOGIES?
Independent Indians possess Unassuming DEPENDENCE on e-gadgets : ADDICTION
(Modern youngsters – typical example)(Modern youngsters – typical example)
Nation’s self sufficiency in FOOD, WATER & ENERGY – Debatable……..
Life without FOOD - 1 week
Life without WATER - 1 day 118 Cr (91.7% of Population) – Mobile users
Life without AIR - 1 minute
LIFE without e– gadgets: IMPOSSIBLE (fraction of minute /seconds)
Today’s e-tools: Ornaments / (communication) Vehicles / Outlet / Asset
EnvironmentEnvironment : Biological & “e-enviro” ; Waste:Waste: Bio & e-waste [Bio sphere vs. e-sphere?]
ENERGY - Indigenous Energy - MANTRA of the current e-society
Industrial Conclave - Platform to showcase CSIR & CECRI’s contributions
towards CLEAN, GREEN & SUSTAINABLE ENERGY

3.  Reduction in Carbon intensity (as per COP 21 & 22) – NEED OF THE HOUR
(E-mobility & Conversion of CO2 to value added products)
 300 million have no access to Electricity - Power for all in an Environment-friendly way
(Mapping/Tapping of energy & Waste-to-wealth: Electrochemistry offers Greener Strategies )
 Capability building for national self-sufficiency on Energy Generation, Conversion & Storage
(National Mission for Electric Mobility & CSIR’s ENERGY MISSION - Solution providers)
 Generation: Fuel Cells; Conversion: DSSC/ OPV; Storage: Batteries & Supercapacitors
 Fuel CellsFuel Cells: Adequate, affordable and clean energy for all
 Lithium Technology & Beyond LithiumLithium Technology & Beyond Lithium : e-gadgets & e-mobility
 Redox Flow BatteriesRedox Flow Batteries : Large scale storage and distribution applications
 SupercapacitorsSupercapacitors: Hybrid electric vehicles
 Lead acid batteriesLead acid batteries: Stationary and hybrid electric vehicle applications
ENERGY: NATIONAL PRIORITY & CSIR / CECRI’s CONTRIBUTION
CECRI’s CORE STRENGTH
