Abstract

World is facing a problem of energy crises and air pollution because of industrialization, increasing populations, transportation, etc. and this has become a burning problem for today and it will continue to become graver in future. It is all because of over-exploitation of natural resources of energy like wood, coal, kerosene, petrol, diesel, etc. being supported by deforestation due to construction activities like buildings, roads, etc. We have reached an alarming situation and if proper action is not taken at this stage, we are bound to face many unwanted situations like rising of sea level due to melting of glaciers, rising temperature of atmosphere, ozone layer depletion, etc. This is all because of global warming caused by all these anthropogenic activities. This will result into natural catastrophes such as flood in many areas while draught in the other areas, hot summer, and chilling winter. One has to find solution to these undesired problems and therefore, efforts are to be made to search an alternate fuel, which will resolve the scarcity of fuels as well as control the global warming. Here, hydrogen enters the scene.
