IOC - IIT Kharagpur develop special type of cylinder to store hydrogen in vehicles

Hydrogen is a very reactive element, which is why you'd never find it by itself in Nature. When you put it in a cylinder, in order to store it, it causes "embrittlement".

To overcome embrittlement, Indian Oil Corporation, India's largest, state-owned refinery, has been working with the Indian Institute of Technology, Kharagpur, to develop a special type of cylinder material.

The research has yielded success and the material is currently undergoing tests. 



The cylinders that will be producing using the material will be used for automotive applications--store vehicles in buses and trucks to feed fuel cells.

The prototypes have been developed. The idea is to be able to produce either type-III (carbon composite with metal liner) or a type-IV (carbon composite with polymer liner) cylinder that can withstand hydrogen at 650 bars pressure. 

Since the currently permitted pressure is 300 bars, IOC has applied to the Petroleum and Explosives Safety Organisation (PESO), of the government of India, to make cylinders for 650 bars, according to sources in IOC.
