With increasing concern on energy security and energy efficiency, automobile industry has been conducting many research on technologies aimed at reducing weight and reducing fuel consumption thereby reducing carbon footprint of the vehicle without compromising safety, efficiency and operational ability. Alternative fuel vehicles such as Compressed Natural Gas (CNG), Liquefied Petroleum Gas (LPG), Hydrogen, Hydrogen-CNG (HCNG) blends and Liquefied Natural Gas (LNG) vehicles are some of the best solutions to minimize the dependence on fossil fuels which are depleting fast. Gas cylinders are the heavier portion of alternative fuel systems which adds more weight to vehicle unladen weight. In search of innovative materials for gas cylinders, composite materials have been the front runner in reducing weight of the vehicle, thereby reducing fuel consumption significantly.

There are no Indian and International standards on load bearing elements. There is a British Standard which specifies only the load requirements of Headboard, side walls and rear gate in case of sudden braking. This paper specifies in detail the load bearing elements and through Computer Aided Engineering (CAE) simulation, the percentage of load that can be borne by the load bearing elements under different types of load shifting has been determined.
