1. it is plentiful
   when you burn it, it makes water

   problems are that except at extremely low temperatures (close to absolute zero) it is a gas and that such gas is explosive (in college we used to make hydrogen balloons and set the string on fire. when the flame reached the balloon we’d get a nice fireball)

2. When it is burnet to produce energy, hydrogen produces water (H2O), unlike CO2, which is a polluting gas.

3. when H bonds to OH in a fuel cell it releases a good deal of energy and its only biproduct are heat and H2O. . . pure water so its very clean

4. Hydrogen does not produce any carbon dioxide when burned or used in a fuel cell – just water. So it is clean and efficient. Unfortunately, carbon monoxide is produced when hydrogen is produced from natural gas (in the steam reformation of methane), so it isn’t really that green if it produced from fossil fuels, which is how it is done currently on an industrial scale.

5. As previous posters have probably said, it’s not an alternative energy but an energy storage device. Nothing wrong with this; it’s a decent way to store alternative energy for use at a later time when the alternative energy source might not be working (dark, no wind…). Until batteries or super capacitors are improved, it’s a cheap way of storing energy and can be used in many different ways.

6. dude by using hydrogen we can reduce our carbon emission and save the mother earth.but problem is that we don’t have enough amount of hydrogen.

7. the only way hydrogen can be produced with little impact is if a nuclear power plant is built near an ocean to desalinate water and produce hydrogen.

8. None. If there were a benefit, we’d be using it.
