hydrogen energy

My presentation is on hydrogen energy and how it is a more efficient way of using a natural resource as an enviornmental friendly item instead of polluting the community and the air using fossil fuels that cause the ozone layer to thin out and global warming. However hydrogen is very expensive and can be difficult to store in small places. Hydrogen releases water vapor instead of all the other fossil fuels that release pollutants that hurt the enviornment. They are now making cars that run on hydrogen fuel instead of fossil fuels. Although we may run out of fossil fuels we still need them to survive so it would be better to have an alternative resource to expand our uses for fuel and other things. This is why i think we should use hydrogen fuel and reduce the use of fossil fuels so we wont have to deal with global warming and thinning the ozone layer.
