The use of fossil fuels is required to create pure hydrogen. APEX!
Burning ethanol releases greenhouse gases.
Well the major use of Hydrogen is in the manufacture of ammonia (NH3), which is used as a fertilizer or converted into other nitrogen-containing fertilizers.
Because if released in the air(oxygen) the mixture becomes explosive. Remember in the lab. to test for hydrogen is the 'pop' test. This is hydrogen igniting with oxygen.
^ Good effort with the question phrasing. Hydrogen is a key component of all the major biological molecules of our bodies (carbohydrates, proteins, lipids etc..) and it's an essential component of water which is our transport mechanism for oxygen via the blood. Hydrogen is life. Life is hydrogen. Without each other they are nothing.

Hydrogen is a major component of carbohydrates, which our bodies use as an energy source.
You can use the hydrogen in fuel cells for power generation for a two wheeler motorcycle.
A drawback is a negative aspect in contrast to a positive change. Example : "The drawback to increased crop production was a drop in the price for farmers."
The Hydrogen bomb was a major fear that people in postwar America had about the use of nuclear weapons.
