Propelling the Hydrogen Economy in India
Propelling the Hydrogen Economy in India
The creation of a novel nano-material for the storage of hydrogen gas via physisorption mechanisms in order to achieve efficient, reliable and fast kinetics of adsorption and desorption
Introduction
Introduction
Ever-growing energy consumption
Depletion of conventional fossil fuels
Increasing global pollution.
Demands for an efficient alternative to meet the energy, the pollution and the climate challenges.
Hydrogen has been considered as a promising bidder.
Developing safe, reliable, compact, and cost-effective hydrogen storage technologies is one of the most technically challenging barriers to the widespread use of hydrogen as a form of energy.

Current scenario
With current technology, 5 Kg of hydrogen can run fuel cell cars for 500 Km.
And 5Kg of hydrogen gas is currently stored in high compression cylinder at 700 bar.
On board cylinders at such high pressure is a safety risk, and also requires release systems that can handle these extreme pressure (valves, pipes, connectors, etc. ).
Thus, there is an issue of safety and reliability of these storage systems
We are targeting to fabricate a small high-pressure cylinder with a maximum working pressure of 100 bar with 200L capacity storing ~1Kg of gas.
In this storage system, solid state materials developed through our investigations will be added to improve its storage capacity.

Thinnest material & practically transparent (97.7%)
Stiffest & strongest (E ~ 1 TPa, σ ~ 130 GPa)
Largest surface-to-weight ratio (~ 2,700 m2/gram)
Very stretchable (up to 20%)
Conducts heat and electricity better than any metal.
