INTRODUCTIONINTRODUCTION

It is well known that the main source for the

production of electricity is fossil fuels.

But it is becoming extinct day by day and hencehydrogen is found to be suitable source.

Hydrogen on burning releases energy and easily

generates electricity through fuel cells.

CONCLUSIONCONCLUSION

The process of Hydrogen production from wasteThe process of Hydrogen production from waste

water can minimize the waste disposal problem and ifwater can minimize the waste disposal problem and if

this process is integrated with waste treatment processthis process is integrated with waste treatment process

then the cost of production of Hydrogen will bethen the cost of production of Hydrogen will befurther reduced.further reduced.

Thus production of Hydrogen from solar poweredThus production of Hydrogen from solar powered
