A Review on Hydrogen Energy

Abstract

In the age of over increasing demand of energy, hydrogen may play a major role as an alternative fuel. Hydrogen can be used as transportation fuel, whereas neither nucleazr nor solar energy can be used directly. Hydrogen has very special property as a transportations fuel, including rapid burning speed, a high effective octane number and no toxicity or ozone forming potential. A stoichiometric hydrogen-are mixture has very minimum ignition energy of 0.02MJ. Combustion product of hydrogen is clean, which consist of water & a little amount of nitrides of oxygen (NOx). The main drawback of using hydrogen as a transportations fuel are huge on - board storage tank. Hydrogen stores approx. 2.6 times more energy per unit mass than gasoline. The disadvantage is that it need an estimated 4 times more volume than gasoline to store that energy. The production and storage of hydrogen are not yet standardized. This paper review the different production technique and storage system of hydrogen to be used as a I C Engine fuel. The desirable and undesirable properties of hydrogen as a I C engine fuel have also been discussed.

Keywords: Alternative fuel hydrogen, Production, Storage.
